Abstract
The indications for bone block augmentation of the glenoid following recurrent anterior shoulder instability are expanding. Arthroscopic anatomic glenoid reconstruction (AAGR) is an evolving technique with similar clinical results to the Latarjet procedure and other open bone block procedures. Multiple types of bone grafts and fixation techniques have been described, with varying results on bony integration, resorption, articular congruity, and recurrence rates. This review focuses on biomechanics, patient workup, indications, current evidence, and the authors' preferred surgical technique for AAGR.

Abstract
Background The Chinese unique inlay Bristow (Cuistow) procedure is a modified Bristow surgery in which an inlay (mortise-and-tenon) structure is added to the contact surface between the coracoid tip and the glenoid. Patients who have undergone the Cuistow procedure have had satisfying clinical performance and excellent postoperative bone healing rates (96.1%). Purpose To compare the clinical and radiographic outcomes after the arthroscopic Cuistow procedure and the arthroscopic Bristow procedure. Study Design Cohort study; Level of evidence, 3. Methods A total of 91 patients who underwent either the Cuistow or Bristow procedure between January 2017 and March 2018 were selected, and 69 patients (70 shoulders; 35 in the Cuistow group and 35 in the Bristow group) were included. Clinical assessment at minimum 24 months postoperatively, including the visual analog scale for pain and instability, American Shoulder and Elbow Surgeons score, Rowe score, subjective shoulder value score, and active range of motion, was completed by independent observers and compared with values collected preoperatively. Assessment with 3-dimensional computed tomography scans was performed preoperatively; immediately after the operation; at 3, 6, and 12 months postoperatively; and at the final follow-up. Results A total of 69 patients (70 shoulders) were included, with a mean follow-up duration of 34.41 ± 5.99 months (range, 24-50 months). Both groups saw significant improvement in visual analog scale for pain and instability, American Shoulder and Elbow Surgeons, Rowe, and subjective shoulder value scores at the final follow-up compared with the preoperative values (P < .001 for all), with no significant between-group differences on any clinical outcomes at the final follow-up. The 3-month postoperative graft union rate on computed tomography was significantly higher in the Cuistow group compared with the Bristow group (82.9% vs 51.4%, respectively, P = .003), although the graft union rate at the final follow-up was not significantly different (94.3% vs 85.7%, respectively; P = .449). Conclusion Patients receiving the Cuistow procedure had equivalent clinical outcomes and a significantly higher bone union rate at 3 months postoperatively than those in the Bristow group. The inlay structure used in the Cuistow procedure was found to be associated with accelerated bone union.

An assessment of the clinical relevance of coracoid graft osteolysis following the Latarjet procedure: a clinical and radiological review. JSES Int 2024; 8:719-723. [PMID: 39035664 PMCID: PMC11258820 DOI: 10.1016/j.jseint.2024.03.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 07/23/2024] Open
Abstract
Background The Latarjet procedure was developed for the treatment of anterior shoulder instability in young, high-demand patients with attritional glenoid bone loss, whose risk of redislocation following primary dislocation may exceed 90%. Coracoid graft osteolysis and prominent screws are commonly observed in late computed tomography (CT) scans of patients who re-present following the procedure, but the clinical relevance of osteolysis in the overall Latarjet cohort is undetermined. We aimed to evaluate clinical and radiological outcomes in patients who underwent the Latarjet procedure, and to determine if severe coracoid graft osteolysis compromised clinical outcomes. Methods This was a retrospective analysis of patients who underwent the open Latarjet procedure. Patients were invited via an e-questionnaire that contained a Western Ontario Shoulder Instability Index (WOSI), and queried about redislocation and reoperation since index surgery. Preoperative glenoid bone loss was calculated on CT using the best-fit circle method. Osteolysis was graded (0, screw head buried in graft; 1, screw head exposed; 2, threads exposed; 3, complete resorption/severe osteolysis) at the level of the proximal and distal screws respectively, on axial CT scans performed ≥ 12 months postoperatively. Results Between 2011 and 2022, a single surgeon performed 442 Latarjet procedures. One hundred fifty eight patients responded to the questionnaire at median (interquartile range [IQR]) 44 (27-70) months postoperatively, among whom the median (IQR) WOSI score was 352 (142-666) points (0 = best, 2100 = worst). Recurrent anterior instability occurred in 3/158 (2%) patients. One patient required reoperation for this indication. Among patients who had CT scans ≥ 12 months postoperatively (median [IQR] 40 [29-69] months), 1 patient developed severe osteolysis around both screws (WOSI = 90), 17/62 (27%) patients developed severe osteolysis around 1 screw, all of which were proximal (median [IQR] WOSI = 235 [135-644]), and 44/62 (71%) patients did not develop severe osteolysis around either screw (median [IQR] WOSI = 487 [177-815]). There were no statistically significant differences in WOSI scores between groups based on the presence of severe osteolysis. Conclusion The Latarjet is reliable procedure that has a low rate of redislocation and reoperation. Severe coracoid graft osteolysis occurs with time, and always affects the proximal graft first. The presence of severe osteolysis did not compromise clinical outcomes.

Arthroscopy 2024; 40:1894-1896.

Abstract
Orthopaedic suture buttons have been increasingly used in a variety of procedures, such as syndesmosis stabilization, coracoclavicular ligament repair, anterior cruciate ligament graft fixation, and Lisfranc injury treatment. In many instances, suture-button fixation constructs have shown equivalent, if not superior, outcomes to screw fixation. More recently, suture buttons have been suggested for osseous fixation of the coracoid during the Latarjet procedure, as well as other anterior (or posterior) bone block reconstruction of the glenoid using distal tibial allograft, tricortical iliac crest, or distal clavicle in cases of complex shoulder instability. Suture buttons offer several unique advantages, including the ability to tension and retension graft fixation, smaller driller paths with bone preservation, less osteolysis, lower risk of hardware removal, and greater ease of hardware revision and/or secondary surgery. However, certain disadvantages also exist, such as higher implant costs, less time-zero implant rigidity, technical difficulty, and, potentially, less mediolateral stability of the bone graft. Time will tell if these suture-button constructs will supplant traditional screw fixation for the Latarjet procedure in terms of clinical and cost-effectiveness.

Abstract
Background The success of glenoid augmentation procedures depends on accurate placement and healing of the graft to the glenoid. Different glenoid augmentation techniques have been described, but no comparative studies between them exist. Purpose To assess the bone graft position, healing, and resorption in a group of patients treated with 1 of 4 procedures: arthroscopic anterior bone-block procedure using either (1) fresh-frozen iliac crest allograft or (2) iliac crest autograft, (3) open Latarjet, or (4) arthroscopic Latarjet. Study Design Cohort study; Level of evidence, 3. Methods A total of 40 patients (87.5% men; mean age, 29.5 ± 7.9 years) were included, with 10 patients in each of the procedure groups. The graft position in the axial and sagittal planes was assessed on postoperative computed tomography (CT). Graft healing and resorption were assessed in a second CT scan performed 1 year postoperatively. Qualitative variables were compared between the 4 procedures using the chi-square test, and quantitative variables were compared with the Student t test or Mann-Whitney U test. Results No differences were found between the procedures in the axial or sagittal position. The healing rate was significantly lower in the allograft bone-block group (20%) compared with the autograft bone-block (80%), open Latarjet (90%), and arthroscopic Latarjet (90%) groups (P < .001). Graft resorption developed in 17 of 40 (42.5%) cases overall. Osteolysis occurred in 100% of cases in the allograft bone-block group compared with 50% in the autograft group, 20% in the open Latarjet group, and 0% in the arthroscopic Latarjet group (P < .001). The glenoid surface area on 1-year CT scan was significantly lower in the allograft bone-block group compared with the autograft bone-block, open Latarjet, and arthroscopic Latarjet groups (P < .001). Conclusion Arthroscopic bone-block, open Latarjet, and arthroscopic Latarjet procedures provided accurate bone graft positioning. However, very high rates of osteolysis and nonunion were observed in the iliac crest fresh-frozen allograft bone-block procedure when compared with the other procedures.

Abstract
BACKGROUND Several arthroscopic glenoid bone augmentation techniques have been introduced to treat patients affected by anterior shoulder instability associated with critical bone loss. The efficacy of the different arthroscopic bony procedures has not been compared yet. PURPOSE To compare the recurrence, complication, and reoperation rates of the arthroscopic Latarjet (AL) and arthroscopic free bone block (ABB) procedures for anterior shoulder instability. STUDY DESIGN Meta-analysis and systematic review; Level of evidence, 4. METHODS A systematic search was conducted in MEDLINE/PubMed, Web of Science, and Embase to identify clinical studies reporting the outcomes of the AL and ABB procedures. The following search phrases were used: "Arthroscopic" AND "Bone Block" OR "Bone Graft," and "Arthroscopic" AND "Glenoid Augmentation" OR "Glenoid Reconstruction," and "Arthroscopic" AND "Latarjet" OR "Coracoid Graft" OR "Coracoid Transfer." Exclusion criteria were <24 months of minimum follow-up, sample size <10 cases, revision after previous glenoid bone grafting, epilepsy, and multidirectional instability. Data regarding the study design, patient characteristics, surgical technique, and outcomes were extracted and analyzed. A proportional meta-analysis was conducted to compare the complication, recurrence, and reoperation rates between the 2 groups. Multiple subgroup analyses were performed to analyze the incidence of each complication and assess the weight of different fixation methods (in the whole cohort) or different graft types (in the ABB group). The modified Coleman Methodology Score was used to assess the risk of bias. RESULTS Of 5010 potentially relevant studies, 18 studies regarding the AL procedure (908 cases) and 15 studies regarding the ABB procedure (469 cases) were included. The 2 groups were comparable in age (P = .07), sex (P = .14), glenoid bone loss (P = .14), number of preoperative dislocations (P = .62), proportion of primary and revision procedures (P = .95), length of follow-up (P = .81), modified Coleman Methodology Score (P = .21), and level of evidence (P = .49). There was no difference in the recurrence (P = .88), reoperation (P = .79), and complication (P = .08) rates. The subgroup analyses showed a higher rate of hardware-related complications for screw fixation compared with flexible fixation (P = .01). CONCLUSION The AL and ABB procedures had similar recurrence, reoperation, and complication rates. Screw fixation of the bone graft was related to an increased risk of complications compared with flexible fixation. REGISTRATION CRD42022368153 (PROSPERO).

Abstract
PURPOSE OF REVIEW This paper aims to analyze and compare the existing research on open and arthroscopic Latarjet procedures for treating anterior shoulder instability. The review will assess different factors such as graft positioning, functional outcomes, complications, and return-to-play rates for both approaches. The study's primary goal is to establish which technique yields superior outcomes. RECENT FINDINGS Recent studies have suggested that arthroscopic Latarjet surgery can produce outcomes similar to open surgery regarding functional scores and patient satisfaction. Some research indicates that arthroscopy may even provide slightly better results. Both techniques have similar complication rates, but arthroscopy requires a longer learning curve and operating time. It is crucial to ensure the proper placement of the graft, and some studies suggest that arthroscopy may be better at achieving accurate positioning. Both open and arthroscopic Latarjet procedures are equally effective in treating shoulder instability. While arthroscopy offers a faster recovery time and causes less soft tissue damage, it requires surgeons to undergo a steeper learning curve. The optimal graft position for both techniques is still debated. More long-term data is needed to establish superiority. Future research should compare approaches in larger cohorts and identify outcome-affecting factors to improve the treatment of shoulder instability. Both techniques are promising, but arthroscopy may be a better option as the procedure evolves into a less invasive reconstruction.

Abstract
PURPOSE To analyze radiographic outcomes by conventional radiography, computed tomography (CT), or both and complication rates of open coracoid transfer at a minimum of 12-months follow-up. METHODS A literature search was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, using PubMed, Medline (Ovid), and EMBASE library databases. Inclusion criteria were clinical studies reporting on open Latarjet as the primary surgical procedure(revision coracoid transfer after failed prior stabilization excluded) with postoperative radiographic outcomes at a minimum mean 1-year follow-up. Patient demographics, type of postoperative imaging modality, and radiographic outcomes and complications including graft union, osteoarthritis, and osteolysis were systematically reviewed. Data were summarized as ranges of reported values for each outcome metric. Each radiographic outcome was graphically represented in a Forest plot with point estimates of the incidence of radiographic outcomes with corresponding 95% confidence intervals and I2. RESULTS Thirty-three studies met inclusion criteria, with a total of 1,456 shoulders. The most common postoperative imaging modality was plain radiography only (n = 848 [58.2%]), both CT and radiography (n = 287 [19.7%]), and CT only (n = 321 [22.1%]). Overall, the reported graft union rate ranged from 75% to 100%, of which 79.8% (n = 395) were detected on plain radiography. The most common reported postoperative radiographic complications after the open coracoid transfer were osteoarthritis (range, 0%-100%, pooled mean 28%), graft osteolysis (range, 0%-100%, pooled mean 30%), nonunion (range, 0%-32%, pooled mean 5.1%), malpositioned graft (range, 0%-75%, pooled mean 14.75%), hardware issues (range, 0%-9.1%, pooled mean 5%), and bone block fracture (range, 0%-8%, pooled mean 2.1%). Graft healing was achieved in a majority of cases (range, 75%-100%). CONCLUSION Postoperative radiographic outcomes after open coracoid transfer vary greatly in definition, classification, and imaging modality of choice. Greater consistency in postoperative radiographic outcomes is essential to evaluate graft healing, osteolysis, and nonunion. LEVEL OF EVIDENCE Level IV, systematic review of Level III-IV studies.

A case-control study with computed tomography scan data. J Shoulder Elbow Surg 2024; 33:e223-e230.

Abstract
BACKGROUND The Latarjet procedure is commonly performed in the treatment of recurrent shoulder instability and is also indicated as a salvage procedure for recurrence after failed arthroscopic Bankart repair. Although this procedure has shown success, there has been an increased awareness of complications in recent studies, especially graft osteolysis. Most relevant research has focused on the pathophysiology, incidence, or location of graft osteolysis or the risk factors for graft osteolysis; however, the data are limited to primary Latarjet procedures. This study aimed to investigate the effect of previous arthroscopic Bankart repair surgery on coracoid bone graft osteolysis in the Latarjet procedure. METHODS This retrospective case-control study analyzed data from patients who underwent primary Latarjet procedures or revision Latarjet procedures following failed arthroscopic Bankart repair. Clinical outcome measures included range of motion, the Subjective Shoulder Value, and the Rowe score. Volumetric analysis of each transferred coracoid graft was performed using early postoperative and late postoperative computed tomography scan data, and the amount of graft osteolysis was then calculated as the percentage of volume reduction of each graft. RESULTS A total of 32 patients who met the inclusion criteria were included in this study, with 24 patients in the primary Latarjet group (group I) and 8 patients in the revision Latarjet group (group II). The mean age of the patients was 32.5 ± 7.7 years, and the mean follow-up duration was 52.1 ± 8.9 months. Both study groups showed significant improvement in the Subjective Shoulder Value compared with baseline (P < .05). Comparison of postoperative clinical outcome measures showed no significant difference in any outcome parameter between the 2 study groups (P > .05). No recurrence was observed during the follow-up period. A positive apprehension sign was present in 6 patients (25%) in group I and 4 patients (50%) in group II (P > .05). Analysis of radiologic data revealed that all patients underwent some degree of graft osteolysis, with varying osteolysis ratios between 12% and 98%. The mean osteolysis ratio of the coracoid graft was 67.3% ± 22.6% in group I and 69.4% ± 25.6% in group II, with no significant difference between the 2 groups (P > .05). CONCLUSION The findings of this study suggest that a considerable amount of coracoid graft osteolysis is observed after both primary Latarjet procedures and revision Latarjet procedures following failed arthroscopic Bankart repair. Previous arthroscopic Bankart repair did not seem to have a significant influence on the amount of graft osteolysis, and both primary and revision Latarjet procedures showed satisfactory clinical outcomes.

Abstract
BACKGROUND The use of a distal tibial allograft (DTA) for reconstruction of a glenoid defect in anterior shoulder instability has grown significantly over the past decade. However, few large-scale clinical studies have investigated the clinical and radiographic outcomes of the DTA procedure. PURPOSE To conduct a systematic review and meta-analysis of clinical studies with data on outcomes and complications in patients who underwent the DTA procedure for recurrent anterior shoulder instability with glenoid bone loss. STUDY DESIGN Systematic review and meta-analysis; Level of evidence, 4. METHODS A comprehensive search of major bibliographic databases was conducted for articles pertaining to the use of a DTA for the management of anterior shoulder instability with associated glenoid bone loss. Postoperative complications and outcomes were extracted and compiled in a meta-analysis. RESULTS Of the 8 included studies with 329 total participants, the mean patient age was 28.1 ± 10.8 years, 192 (83.8%) patients were male, and the mean follow-up was 38.4 ± 20.5 months. The overall complication rate was 7.1%, with hardware complications (3.8%) being the most common. Partial graft resorption was observed in 36.5% of the participants. Recurrent subluxation was reported in 1.2% of the participants, and recurrent dislocation prompting a reoperation was noted in 0.3% of the participants. There were significant improvements in clinical outcomes, including American Shoulder and Elbow Surgeons score (40.9-point increase; P < .01), Single Assessment Numeric Evaluation (47.2-point increase; P < .01), Western Ontario Shoulder Instability Index (49.4-point decrease; P < .01), Disabilities of the Arm, Shoulder and Hand (20.0-point decrease; P = .03), and visual analog scale (2.1-point decrease; P = .05). Additionally, postoperative shoulder range of motion significantly increased from baseline values. CONCLUSION The DTA procedure was associated with a low complication rate, good clinical outcomes, and improved range of motion among patients with anterior shoulder instability and associated glenoid defects.

[PMID: 38435255 PMCID: PMC10907962 DOI: 10.1016/j.eats.2023.10.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/01/2023] [Accepted: 10/27/2023] [Indexed: 03/05/2024] Open
Abstract
The Buford complex is an anatomic variation defined as the association of a cordlike middle glenohumeral ligament (MGHL) and an absent anterosuperior labrum. It can be challenging to properly identify on preoperative imaging and remains mostly an arthroscopic finding. It may, however, lead to problematic situations when encountered during an arthroscopic soft-tissue stabilization procedure, as the treatment of choice in such cases is a bone block. Moreover, reattaching the MGHL to the anterior border of the glenoid rim has traditionally not been recommended because it theoretically leads to severe restriction in external rotation. This technical note describes arthroscopic stabilization for anterior traumatic glenohumeral instability associated with the Buford complex. The cordlike MGHL is used to reconstruct a neo-labrum, associated with an anteroinferior glenohumeral ligament plication. Glenohumeral stabilization using the cordlike MGHL of the Buford complex may be an efficient alternative to a bone block procedure.

J Orthop Sci 2023:S0949-2658(23)00324-X. [PMID: 38030446 DOI: 10.1016/j.jos.2023.11.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/31/2023] [Revised: 11/08/2023] [Accepted: 11/14/2023] [Indexed: 12/01/2023]
Abstract
BACKGROUND The Bristow procedure has been shown to be a reliable method to prevent recurrent anterior shoulder instability by compensating for glenoid bone loss and producing the sling effect. The degree of postoperative morphological change in the coracoid bone graft is speculated to influence glenohumeral joint stability; however, the details of these changes after the Bristow procedure remain unknown. This study was performed to quantify the postoperative change in the coracoid bone graft volume as assessed by three-dimensional computed tomography (3D-CT). METHODS The Bristow procedure was performed on 17 shoulders in 17 patients from August 2018 to January 2020. All patients were men, and their mean age at surgery was 17.9 years. The mean follow-up duration was 21.4 months. Within the first week after the operation (Time 0) and at the final follow-up, 3D-CT was used to determine the total coracoid bone graft volume. The clinical outcomes were evaluated using the Japanese Orthopaedic Association (JOA) shoulder score, the University of California Los Angeles (UCLA) shoulder score, and the Western Ontario Shoulder Instability Index (WOSI). RESULTS The mean volume of the total coracoid bone graft was 1.26 ± 0.29 cm3 at Time 0 and 1.90 ± 0.36 cm3 at the final follow-up (p < 0.0001). The mean JOA score, UCLA score, and WOSI were significantly better at the final follow-up than preoperatively (p < 0.001). No postoperative infection, neurovascular injury, or recurrent instability of the glenohumeral joint occurred. CONCLUSIONS In the Bristow procedure, the volume of the total coracoid bone graft as shown by 3D-CT was significantly greater at the final follow-up than at Time 0, and bone formation of the coracoid bone graft was found after the Bristow procedure.

Remodeling process and clinical outcomes following all-arthroscopic modified Eden-Hybinette procedure using iliac crest autograft and 1-tunnel double Endobutton fixation system. J Shoulder Elbow Surg 2023; 32:1825-1837. [PMID: 36907316 DOI: 10.1016/j.jse.2023.01.041] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/15/2022] [Revised: 01/25/2023] [Accepted: 01/27/2023] [Indexed: 03/14/2023]
Abstract
BACKGROUND Arthroscopically modified Eden-Hybinette procedures for glenohumeral stabilization have been used for a long time. With the advancement of arthroscopic techniques and the development of sophisticated instruments, a double Endobutton fixation system has been used clinically to secure bone graft to the glenoid rim placed through a specifically designed guide. The purpose of this report was to evaluate clinical outcomes and serial glenoid remodeling process following all-arthroscopic anatomical glenoid reconstruction using autologous iliac crest bone grafting technique through 1-tunnel fixation. METHODS Forty-six patients with recurrent anterior dislocations and significant glenoid defects greater than 20% underwent arthroscopic surgery with a modified Eden-Hybinette technique. Instead of firm fixation, autologous iliac bone graft was fixed to the glenoid by double Endobutton fixation system through 1-tunnel placed in the glenoid surface. Follow-up examinations were performed at 3, 6, 12, and 24 months. The patients were followed up for a minimum of two years using the Rowe score, the Constant score, the Subjective Shoulder Value, and the Walch-Duplay score; patient satisfaction with the procedure outcome was also rated. Graft positions, healing, and absorption were evaluated postoperatively with computed tomography imaging. RESULTS At a mean follow-up of 28 months, all patients were satisfied and had a stable shoulder. The Constant score improved from 82.9 to 88.9 points (P < .001), the Rowe score, improved from 25.3 to 89.1 points (P < .001), the Subjective Shoulder Value improved from 31% to 87% (P < .001), and the Walch-Duplay score improved from 52.5 to 85.7 points (P < .001). One donor-site fracture occurred during the follow-up period. All grafts were well-positioned and achieved optimal bone healing with zero excessive absorption. The preoperative glenoid surface (72.6% ± 4.5%) increased significantly immediately after surgery to 116.5% ± 9.6% (P < .001). After a physiological remodeling process, the glenoid surface remained significantly increased at the last follow-up (99.2% ± 7.1%) (P < .001). The glenoid surface area appeared to decrease serially when compared between the first 6 months and 12 months postoperatively, while there was no significant interval change between 12 and 24 months postoperatively. CONCLUSION Patient outcomes were satisfactory following the all-arthroscopic modified Eden-Hybinette procedure using an autologous iliac crest grafting technique through one-tunnel fixation system with double Endobutton. Graft absorption mostly occurred on the edge and outside the ''best-fit'' circle of the glenoid. Glenoid remodeling occurred within the first year after all-arthroscopic glenoid reconstruction with an auto iliac bone graft.

Abstract
BACKGROUND Glenohumeral joint contact loading before and after glenoid bone grafting for recurrent anterior instability remains poorly understood. PURPOSE To develop a computational model to evaluate the influence of glenoid bone loss and graft positioning on graft and cartilage contact pressures after the Latarjet procedure. STUDY DESIGN Controlled laboratory study. METHODS A finite element model of the shoulder was developed using kinematics, muscle and glenohumeral joint loading of 6 male participants. Muscle and joint forces at 90° of abduction and external rotation were calculated and employed in simulations of the native shoulder, as well as the shoulder with a Bankart lesion, 10% and 25% glenoid bone loss, and after the Latarjet procedure. RESULTS A Bankart lesion as well as glenoid bone loss of 10% and 25% significantly increased glenoid and humeral cartilage contact pressures compared with the native shoulder (P < .05). The Latarjet procedure did not significantly increase glenoid cartilage contact pressure. With 25% glenoid bone loss, the Latarjet procedure with a graft flush with the glenoid and the humerus positioned at the glenoid half-width resulted in significantly increased humeral cartilage contact pressure compared with that preoperatively (P = .023). Under the same condition, medializing the graft by 1 mm resulted in humeral cartilage contact pressure comparable with that preoperatively (P = .097). Graft lateralization by 1 mm resulted in significantly increased humeral cartilage contact pressure in both glenoid bone loss conditions (P < .05). CONCLUSION This modeling study showed that labral damage and greater glenoid bone loss significantly increased glenoid and humeral cartilage contact pressures in the shoulder. The Latarjet procedure may mitigate this to an extent, although glenoid and humeral contact loading was sensitive to graft placement. CLINICAL RELEVANCE The Latarjet procedure with a correctly positioned graft should not lead to increased glenohumeral joint contact loading. The present study suggests that lateral graft overhang should be avoided, and in the situation of large glenoid bone defects, slight medialization (ie, 1 mm) of the graft may help to mitigate glenohumeral joint contact overloading.

Abstract
BACKGROUND Nonrigid fixation techniques have been recently introduced in free bone block (FBB) procedures to treat substantial glenoid bone loss in patients with anterior shoulder instability. However, the radiological and histological effectiveness of nonrigid fixation versus conventional rigid fixation have not been comprehensively understood in vivo. PURPOSE To (1) explore the radiological and histological characteristics of nonrigid fixation for FBB procedures in a rabbit model of glenoid defects and (2) further compare them with those of conventional rigid fixation. STUDY DESIGN Controlled laboratory study. METHODS Unilateral shoulder glenoid defects were created in 36 mature New Zealand White rabbits, of which 24 underwent FBB procedures using allogenic iliac crest bone and were randomly divided into rigid fixation (RF) and nonrigid fixation (N-RF) groups, with the remaining divided into 2 control groups: 6 with sham surgery for glenoid defects (GD group) and 6 native glenoids (normal group). In the RF and N-RF groups, 6 rabbits were sacrificed at 6 or 12 weeks postoperatively for radiological and histological analyses of the reconstructed glenoid, and all rabbits in the GD and normal groups were sacrificed at 12 weeks. The radiological glenoid morphology was evaluated via micro-computed tomography. Moreover, the graft-glenoid healing and graft remodeling processes were determined using histological staining. RESULTS At 6 weeks, both the N-RF and RF groups had similarly improved radiological axial radian and en face area of the glenoid compared with the GD group, but the N-RF group showed superiority in restoration of the glenoid radian and area compared with the RF group at 12 weeks, with the native glenoid as the baseline. Histologically, the bone graft in both groups was substantively integrated into the deficient glenoid neck at 6 and 12 weeks, showing similar osseous healing processes at the graft-glenoid junction. Moreover, the bone graft histologically presented similar regenerated vascular density, total graft bone, and integrated graft bone in both groups. In contrast, the N-RF group had a different remodeling profile on radiological and histological analyses regarding regional bone resorption, mineralization, and fibrous tissue replacement during osseointegration. CONCLUSION Compared with rigid fixation, nonrigid fixation resulted in superior reconstructed glenoid morphology radiologically and similar graft-glenoid osseous healing histologically, showing different graft remodeling profiles of regional bone resorption, mineralization, and fibrous tissue replacement. CLINICAL RELEVANCE The nonrigid fixation technique can be feasible for FBB procedures to treat glenoid bone loss in anterior shoulder instability. More clinical evidence is required to determine its pros and cons compared with conventional rigid fixation.

Abstract
HYPOTHESIS The aim of this study was to evaluate the osteolysis rate, graft remodeling, and risk factors for osteolysis at the 1-year threshold after an arthroscopic Latarjet procedure with double-button fixation. METHOD In this multicenter, retrospective study, postoperative computed tomography scans obtained after an arthroscopic Latarjet procedure with double-button fixation to treat anterior shoulder instability were analyzed at 15 days and at 3, 6, and 12 months. Graft volume, dimensions, and morphologic remodeling were analyzed. RESULTS Twenty-seven patients were included (mean age, 26 years). At 1 year, osteolysis occurred in 19 of 27 patients (70%). The volume initially decreased until 6 months' follow-up (-35%; range, -75% to +26%) and then increased until our last follow-up. At 1 year, the graft volume decreased by 17% (range, -61% to +56%) compared with the immediate postoperative volume. In multivariate analysis, the rate of osteolysis was inversely associated with an unhealed graft at 3 months (P = .02; β coefficient = -44.50 [95% confidence interval, -81 to -8]). The maximal height of the graft significantly grew 0.2 cm (range, -55 to +124 mm) (P = .015). In the sagittal plane, osteolysis occurred in the superior part in 100% of patients (27 of 27) whereas bone formation occurred in the inferior part. In the axial plane, osteolysis occurred in the anterior part whereas bone formation occurred in the posterior part. In the articular part, the observed remodeling was aimed to obtain a new anatomic and congruent glenoid. CONCLUSIONS At 1 year after an arthroscopic Latarjet procedure with double-button fixation, osteolysis occurred in 70% of patients. The rate of osteolysis was 17% of the initial volume. Osteolysis occurred mainly during the first 6 months, in the anterior and superior parts. Remodeling led to a circular anatomic glenoid. This osteolysis did not cause any recurrence of instability or require revision surgery.

Abstract
BACKGROUND Posterior open-wedge osteotomy and glenoid reconstruction using a J-shaped iliac crest bone graft showed promising clinical results for the treatment of posterior instability with excessive glenoid retroversion and posteroinferior glenoid deficiency. PURPOSE To evaluate the biomechanical performance of the posterior J-shaped graft to restore glenoid retroversion and posteroinferior deficiency in a cadaveric shoulder instability model. STUDY DESIGN Controlled laboratory study. METHODS A posterior glenoid open-wedge osteotomy was performed in 6 fresh-frozen shoulders, allowing the glenoid retroversion to be set at 0°, 10°, and 20°. At each of these 3 preset angles of glenoid retroversion, the following conditions were simulated: (1) intact joint, (2) posterior Bankart lesion, (3) 20% posteroinferior glenoid deficiency, and (4) posterior J-shaped graft (at 0° of retroversion). With the humerus in the Jerk position (60° of glenohumeral anteflexion, 60° of internal rotation), stability was evaluated by measuring posterior humeral head (HH) translation (in mm) and peak translational force (in N) to translate the HH over 25% of the glenoid width. Glenohumeral contact patterns were measured using pressure-sensitive sensors. Fixation of the posterior J-graft was analyzed by recording graft micromovements during 3000 cycles of 5-mm anteroposterior HH translations. RESULTS Reconstructing the glenoid with a posterior J-graft to 0° of retroversion significantly increased stability compared with a posterior Bankart lesion and posteroinferior glenoid deficiency in all 3 preset degrees of retroversion (P < .05). There was no significant difference in joint stability comparing the posterior J-graft with an intact joint at 0° of retroversion. The posterior J-graft restored mean contact area and contact pressure comparable with that of the intact condition with 0° of retroversion (222 vs 223 mm2, P = .980; and 0.450 vs 0.550 MPa, P = .203). The mean total graft displacement after 3000 cycles of loading was 43 ± 84 µm, and the mean maximal mediolateral graft bending was 508 ± 488 µm. CONCLUSION Biomechanical analysis of the posterior J-graft demonstrated reliable restoration of initial glenohumeral joint stability, normalization of contact patterns comparable with that of an intact shoulder joint with neutral retroversion, and secure initial graft fixation in the cadaveric model. CLINICAL RELEVANCE This study confirms that the posterior J-graft can restore stability and glenohumeral loading conditions comparable with those of an intact shoulder.

Abstract
PURPOSE To retrospectively evaluate clinical and radiologic outcomes and return to sport and to work of patients after arthroscopic Latarjet stabilization for primary instability or revision surgery; factors influencing and determining results and potential predictors for clinical outcomes also were evaluated. METHODS This is a retrospective study including patients older than 18 years old who underwent arthroscopic Latarjet stabilization for recurrent anterior glenohumeral instability with off-track lesions, or for cases of recurrence after previous surgery, from 2011 to 2017. Patients were assessed preoperatively and at a minimum 3 years of follow-up using the Rowe score, the University of California at Los Angeles Shoulder Score and Simple Shoulder Test score; the range of motion, satisfaction rate, return to work and sport, perception of discomfort during sporting and daily activities, and complications and recurrence after surgery were also evaluated. The integration of the coracoid graft and the position of the screws were examined by computed tomography scan. RESULTS At a mean follow-up time of 6 ± 2 years, 93 patients (95 shoulders) showed significant improvement of all scale scores (P < .001), 97.8% of the patients had returned to the same working condition as before surgery, and all the patients who practiced sports preoperatively (85; 91.4%) returned to sport after surgery; 97.9% of patients were satisfied with surgery. The complication rate was 5.4%, and 2 cases (2.1%) of recurrence occurred, both after high-energy trauma. At an average of 17 ± 13 months postoperatively, computed tomography scans showed 4 (6.6%) stable nonunions, 9 (14.8%) superior, and 1 (1.6%) inferior lyses of the graft; a correct positioning of the graft was observed in 86.9% of the cases. Greater satisfaction, fewer complications, less pain during daily activities, and a lower number of reoperations were associated with a shorter time between the first dislocation episode and surgery (P = .019, P < .001, P = .014, and P = .005, respectively). Complications were directly associated with older patient age at operation (P = .001). A greater number of nonunions was found in patients with increased angle between the line linking the posterior and anterior glenoid rim and the screw axis (P = .040) and a medial axial position or a lower coronal position of the graft (both P = .010). A lower age at the time of surgery predicted better Rowe scores at follow-up (P < .001), and a lower age at the time of the first episode of dislocation predicted better postoperative Simple Shoulder Test scores (P = .026). CONCLUSIONS At a mean 6-year follow-up time, excellent clinical outcomes, and radiological results, with few complications, high rates of satisfaction and return to work and sport and low sports anxiety can be expected after arthroscopic Latarjet procedure. A shorter time between the first dislocation episode and surgery was associated with higher satisfaction, fewer complications, less pain during daily activities and lower reoperations; a lower age at the operation was associated with lower complications.

Validation of a Novel Patient Specific CT-Morphometric Technique for Quantifying Bone Graft Resorption Following the Latarjet Procedure. J Clin Med 2022; 11:jcm11195514. [PMID: 36233382 PMCID: PMC9571787 DOI: 10.3390/jcm11195514] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2022] [Revised: 08/09/2022] [Accepted: 09/20/2022] [Indexed: 11/16/2022] Open
Abstract
Bone graft resorption following the Latarjet procedure has received considerable concern. Current methods quantifying bone graft resorption rely on two-dimensional (2D) CT-scans or three-dimensional (3D) techniques, which do not represent the whole graft volume/resorption (i.e., 2D assessment) or expose patients to additional radiation (i.e., 3D assessment) as this technique relies on early postoperative CT-scans. The aim of the present study was to develop and validate a patient-specific, CT-morphometric technique combining image registration with 3D CT-reconstruction to quantify bone graft resorption following the Latarjet procedure for recurrent anterior shoulder instability. Pre-operative and final follow-up CT-scans were segmented to digitally reconstruct 3D scapula geometries. A virtual Latarjet procedure was then conducted to model the timepoint-0 graft volume, which was compared with the final follow-up graft volume. Graft resorption at final follow-up was highly correlated to the 2D gold standard-technique by Zhu (Kendall tau coefficient = 0.73; p < 0.001). The new technique was also found to have excellent inter- and intra-rater reliability (ICC values, 0.931 and 0.991; both p < 0.001). The main finding of this study is that the technique presented is a valid and reliable method that provides the advantage of 3D-assessment of graft resorption at long-term follow-up without the need of an early postoperative CT-scan.

Comparison of two coracoid process transfer techniques on stress shielding using three-dimensional finite-element model. J Orthop Surg Res 2022; 17:371.

Abstract
Background We created patient-based 3D finite-element (FE) models that simulate the congruent-arc Latarjet (CAL) and traditional Latarjet (TL) procedures and then compared their stress distribution patterns with different arm positions and glenoid defects. Methods The computed tomography data of 10 adult patients (9 men and 1 woman, ages: 18–50 years) were used to develop the 3D FE glenohumeral joint models. Twenty-five and 35% bony defects were created on the anterior glenoid rim, and the coracoid process was transferred flush with the glenoid by the traditional and congruent-arc techniques using two half-threaded screws. A load was applied to the greater tuberosity toward the center of the glenoid, and a tensile force (20 N) was applied to the coracoid tip along the direction of the conjoint tendon. The distribution patterns of the von Mises stress in the traditional and congruent-arc Latarjet techniques were compared. Results The mean von Mises on the graft was significantly greater for the TL technique than for the CAL. While the von Mises stress was greater in the distal medial part of the graft in the TL models, a higher stress concentration was observed in the distal lateral edge of the coracoid graft in the CAL models. The proximal medial part of the graft exhibited significantly lower von Mises stress than the distal medial part when compared according to technique, defect size, and arm position. Increasing the glenoid defect from 25 to 35% resulted in a significant increase in stress on the lateral side of the graft in both models. Conclusion The stress distribution patterns and stress magnitude of the coracoid grafts differed according to the procedure. Due to placing less stress on the proximal–medial part of the graft, the CAL technique may lead to insufficient stimulation for bone formation at the graft–glenoid interface, resulting in a higher incidence of graft osteolysis. Clinical relevance The CAL technique may lead to a higher incidence of graft osteolysis. Level of evidence Basic Science Study; Computer Modeling.

Abstract
Arthroscopic Latarjet has evolved as a reproducible procedure to address significant anterior glenoid bone loss in recurrent anterior instability of the shoulder joint. While arthroscopic Bankart procedure for anterior shoulder instability has changed from metal anchors to absorbable or soft all-suture anchors to avoid metal-ware and subsequent abrasion in cases of osteolysis or backout, Latarjet procedure, until recently couple of titanium screws were used to fix the coracoid bone to the anterior glenoid. Arthroscopic techniques for Latarjet procedure of coracoid bone transfer have shown results similar to the open technique in many recent studies. We use an all-arthroscopic technique that is different and easier from the currently described technique using FiberTape cerclage loops, with 2 ultrabraid tapes fixing the coracoid bone to the prepared anteroinferior glenoid surface. The repair is completed using all-suture anchors to fix the anterior capsule over the attached coracoid, thus exteriorizing the transferred bone and preventing contact with the moving humeral head.

Implant-free iliac crest bone graft procedure shows anatomic remodelling without redislocation in recurrent anterior shoulder instability after short-term follow-up. Arch Orthop Trauma Surg 2022; 142:1047-1054.

Abstract
INTRODUCTION With the help of a J-shaped bicortical iliac crest bone graft, the morphology of the glenoid can be augmented without having to use screws to achieve glenohumeral stability. The aim of this retrospective clinical study was to evaluate the clinical stability and function of the shoulder joint as well as the radiological remodelling process and arthropathic outcomes following the J-bone graft technique. MATERIALS AND METHODS 34 patients with recurrent shoulder dislocations and bony glenoid defects were treated with the J-bone graft technique between 2010 and 2018 at our level-I trauma centre. 15 patients (18 shoulders) could be recruited for the study. Pain levels, ASES, UCLA, SST, DASH, Rowe and WOSI Scores were collected using questionnaires. In 13 patients (16 shoulders) the Constant Score, ROM, CT with 3D reconstruction of the glenoid to assess the graft remodelling and X-rays were performed additionally. RESULTS None of the patients suffered subluxations or recurrent dislocations during the follow-up period. The overall complication rate was 11%. The evaluation using objective and subjective shoulder function scores yielded good-to-excellent results. Radiological assessment at follow-up showed a low rate of moderate-to-severe arthritis (12%) and a high rate of shoulders without any signs of arthritic degeneration (53%). The CT scans all revealed an almost complete restoration of the glenoid with none of the grafts being resorbed. A rise in the average glenoid circumference and glenoid area could be demonstrated between preoperative measurements (81.6 and 82.4%, respectively) and follow-up measurements (104 and 102.5%, respectively). CONCLUSION The results of this study show a successful stabilisation of the shoulder joint and a low complication rate following the J-bone graft technique. Remodelling of the bone graft could be demonstrated, which in turn led to an almost perfect glenoid surface area of 100%.

Abstract
Recurrent instability associated with glenoid bone loss is a commonly encountered problem after anterior shoulder dislocation. Surgical management with bony augmentation can be achieved with several allograft or autograft options. Fixation strategies also vary, including screw, suture button, or suture anchor fixation. Concerns exist regarding screw fixation because of the technical difficulty of a medial portal establishment, as well as the potential for graft osteolysis. Suture button fixation for osteochondral graft fixation has been previously described. However, no description of graft fixation using suture anchors exists. We describe an arthroscopic technique for glenoid augmentation using distal tibial allograft with suture anchor fixation.

Abstract
BACKGROUND Bony Bankart lesions can perpetuate chronic anterior glenohumeral instability. When surgical treatment is pursued, several factors need to be considered to obtain optimal outcomes. PURPOSE To (1) quantitatively describe patterns of bone fragment resorption and associated risk factors for developing glenoid bone loss (GBL) and (2) to compare clinical and radiological results of attritional bone loss treated with either the arthroscopic Bankart or the open Latarjet procedure. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS A retrospective analysis of prospectively collected data was conducted for patients who underwent arthroscopic stabilization (group A1, 10%-20% GBL; group A2, >20% GBL) or open Latarjet (group B, >10% GBL) for recurrent shoulder instability with bony Bankart lesion. Patient characteristics, number of dislocations, and Western Ontario Shoulder Instability Index (WOSI) scores were obtained. Pre- and postoperative computed tomography imaging was used to quantitatively describe patterns of bone fragment resorption. RESULTS A total of 120 consecutive patients (group A1, 40; group A2, 23; group B, 57) were included in the study, with a mean age of 25.6 years (range, 19-35 years). The average follow-up was 5.0 years for all groups (range, 4.83-5.16 years in group A1, 4.58-5.41 years in group A2, and 4.33-5.67 years in group B). The mean times between dislocation event and surgery were 12.8 months (range, 6-32 months) and 13.6 months (range, 6-38 months) for groups A and B, respectively. Redislocation rates were 7.5% in group A1 versus 13.0% in group A2, and only occurred in patients with ≥13.5% GBL. There were no redislocations for group B (0%). Patients had better WOSI scores in group B (234.1 ± 126.9) than in group A (576.1 ± 224.6) (P < .0001). In group A, smaller preoperative bone fragment size displayed a higher percentage of resorption after surgery (r = -0.64; P < .05). CONCLUSION A significant inverse relationship exists between preoperative bone fragment size and percentage of postoperative resorption. Patients treated with arthroscopic bony Bankart repair who had final GBL ≥13.5% had worse outcomes. When planned GBL approaches 13.5% in high-demand patients, a smaller fragment size can result in worse clinical outcomes because of resorption. In these cases, choosing the open Latarjet procedure leads to better clinical results.

Abstract
BACKGROUND Traumatic anterior shoulder dislocations can cause bony defects of the anterior glenoid rim and are often associated with recurrent shoulder instability. For large glenoid defects of 20-30% without a mobile bony fragment, glenoid reconstruction with bone grafts is often recommended. This review describes two broad categories of glenoid reconstruction procedures found in literature: coracoid transfers involving the Bristow and Latarjet procedures, and free bone grafting techniques. METHODS An electronic search of MEDLINE and PubMed was conducted to find original articles that described glenoid reconstruction techniques or modifications to existing techniques. RESULTS Coracoid transfers involve the Bristow and Latarjet procedures. Modifications to these procedures such as arthroscopic execution, method of graft attachment and orientation have been described. Free bone grafts have been obtained from the iliac crest, distal tibia, acromion, distal clavicle and femoral condyle. CONCLUSION Both coracoid transfers and free bone grafting procedures are options for reconstructing large bony defects of the anterior glenoid rim and have had similar clinical outcomes. Free bone grafts may offer greater flexibility in graft shaping and choice of graft size depending on the bone stock chosen. Novel developments tend towards minimising invasiveness using arthroscopic approaches and examining alternative non-rigid graft fixation techniques.

Abstract
PURPOSE To report clinical and radiologic outcomes of arthroscopic Eden-Hybinette using 2 cortical suture buttons in a series of patients with previous failed Latarjet and persistent glenoid bone loss. METHODS Between 2015 and 2019, patients with recurrent anterior instability after failed Latarjet underwent arthroscopic Eden-Hybinette procedure using 2 cortical buttons for graft fixation. Exclusion criteria were open and primary Eden-Hybinette and less than one year follow-up. Functional assessment was performed using Rowe and Walch-Duplay scores, subjective shoulder value, visual analog scale, and degree of satisfaction. Iliac crest bone graft placement and healing were assessed postoperatively with computed tomography imaging. RESULTS A total of 17 patients with a mean age of 28 years (range, 21-43 years) at time of revision were included. The mean glenoid bone loss was 23% (range, 18%-42%). Medium or deep Hill-Sachs lesion (Calandra 2 and 3) was present in 65% of cases. At a mean follow-up of 3 ± 1.6 years, all but 1 patient (94%) considered their shoulder stable, and 15 patients (88%) were satisfied or very satisfied. The subjective shoulder value increased from 51% to 87% (P < .05), the Walch-Duplay increased from 23 to 86 points (P < .05), and Rowe scores improved from 30 to 92 points (P < .05). Apprehension was still positive in 3 patients (17.6%), with this percentage being greater in the presence of Hill-Sachs Calandra 3 (P = .02). Postoperative computed tomography scans showed optimal bone autograft position in all patients (below the glenoid equator and flush to the glenoid rim). Iliac crest bone graft healed to the anterior glenoid neck in 16 shoulders (94%). The rate of recurrent instability was 11.7% but only 1 patient required revision surgery (5.8%). CONCLUSIONS Arthroscopic Eden-Hybinette using 2 cortical buttons leads to satisfactory clinical outcomes and a low recurrence rate after failed Latarjet, allowing successful reconstruction of the anterior glenoid rim and simultaneous treatment of capsular deficiency and humeral bone loss. LEVEL OF EVIDENCE Therapeutic, level IV, retrospective case series.

Free bone grafting improves clinical outcomes in anterior shoulder instability with bone defect: a systematic review and meta-analysis of studies with a minimum of 1-year follow-up. J Shoulder Elbow Surg 2022; 31:e190-e208.

Abstract
BACKGROUND Evidence on the efficacy and safety of the free bone grafting in treating anterior shoulder instability is limited. The purpose of this study was to systematically evaluate the clinical and imaging results of free bone grafting in treating anterior shoulder instability with glenoid bone defect and to explore the incidence of complications in clinically relevant subgroups. METHODS This systematic review was conducted per PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines. The PubMed, Embase, and Cochrane Library databases were searched up to January 29, 2021, for studies that had reported on free bone grafting in treating anterior shoulder instability with glenoid bone defect with a minimum of 1-year follow-up. Two researchers independently screened studies and extracted data. A random-effects model was used to pool data on clinical function scores, imaging results, and incidence of complications (recurrent instability and non-instability-related complications). Meta-regression analysis was used to evaluate the incidence of complications in different subgroups and investigate the sources of heterogeneity. RESULTS A total of 29 studies were included in the meta-analysis, comprising 840 patients (845 shoulders) with average ages ranging from 21 to 34.6 years. Compared with preoperatively, free bone grafting increased the postoperative Rowe score, American Shoulder and Elbow Surgeons score, Constant score, Subjective Shoulder Value, and Oxford Shoulder Instability Score by 53.16, 31.80, 20.81, 38.63, and 4.07 points, respectively, and reduced the visual analog scale pain score by 3 points on average. During the postoperative follow-up period, the rates of return to sport and return to preoperative levels were 84.2% and 73.1%, respectively. The imaging results showed that the free bone healing rate was 98.9% and the incidence of osteoarthritis was 10.9%. The incidence rates of recurrent instability and non-instability-related complications were 3.4% and 5.6%, respectively. Meta-regression analysis showed no evidence of effect modification by the year, follow-up time, proportion of male patients, autograft or allograft, and arthroscopy or open surgery on the incidence of complications. Subgroup analysis showed that the incidence rates of recurrent instability for open surgery, arthroscopy, allograft, autograft, Latarjet revision, and non-bone block revision were 4.1%, 2.3%, 1.5%, 4.4%, 10.3%, and 3.5%, respectively. CONCLUSION The application of free bone grafting in treating anterior shoulder instability with glenoid bone defect can effectively improve shoulder joint function and is associated with a high return-to-sport rate and a low overall recurrence rate, but there were some differences in the complications of recurrent instability and non-instability-related complications among the subgroups. Given that these results need to be confirmed via head-to-head comparisons, we recommend that future clinical and biomechanical studies focus on comparing and investigating the advantages and disadvantages of different surgical approaches, thus providing a basis for orthopedic surgeons to make reliable choices.

Revision Shoulder Instability Surgery After Failed Latarjet: Glenoid Reconstruction Using Distal Tibial Allograft and Humeral Head Reconstruction Using Osteochondral Allograft. Arthrosc Tech 2022; 11:e591-e599.

Abstract
Revision surgery for a failed Latarjet procedure is rare and technically demanding with few viable options. Similarly, massive defects to the articular humeral head require thoughtful techniques to recreate a congruent joint. Revision options for failed Latarjet have been studied, but there is yet to be a consensus on graft options. Distal tibial allograft has shown favorable outcomes in midterm data. Humeral head osteochondral allograft has also shown favorable outcomes for very large humeral head defects. However, there is a paucity of literature to demonstrate efficacy of combining the 2 aforementioned techniques. Revision shoulder instability surgery with glenoid reconstruction using distal tibial allograft and humeral head reconstruction using osteochondral allograft restores the glenohumeral articulation while preserving the remaining native bone stock.

Abstract
BACKGROUND Glenohumeral instability caused by bone loss requires adequate bony restoration for successful surgical stabilization. Coracoid transfer has been the gold standard bone graft; however, it has high complication rates. Alternative autologous free bone grafts, which include the distal clavicle and scapular spine, have been suggested. STUDY DESIGN Controlled laboratory study. PURPOSE The purpose of this study was to determine the percentage of glenoid bone loss (GBL) restored via coracoid, distal clavicle, and scapular spine bone grafts using a patient cohort and a cadaveric evaluation. METHODS Autologous bone graft dimensions from a traditional Latarjet, congruent arc Latarjet, distal clavicle, and scapular spine were measured in a 2-part study using 52 computed tomography (CT) scans and 10 unmatched cadaveric specimens. The amount of GBL restored using each graft was calculated by comparing the graft thickness with the glenoid diameter. RESULTS Using CT measurements, we found the mean percentage of glenoid restoration for each graft was 49.5% ± 6.7% (traditional Latarjet), 45.1% ± 4.9% (congruent arc Latarjet), 42.2% ± 7.7% (distal clavicle), and 26.2% ± 8.1% (scapular spine). Using cadaveric measurements, we found the mean percentage of glenoid restoration for each graft was 40.2% ± 5.0% (traditional Latarjet), 53.4% ± 4.7% (congruent arc Latarjet), 45.6% ± 8.4% (distal clavicle), and 28.2% ± 7.7% (scapular spine). With 10% GBL, 100% of the coracoid and distal clavicle grafts, as well as 88% of scapular spine grafts, could restore the defect (P < .001). With 20% GBL, 100% of the coracoid and distal clavicle grafts but only 66% of scapular spine grafts could restore the defect (P < .001). With 30% GBL, 100% of coracoid grafts, 98% of distal clavicle grafts, and 28% of scapular spine grafts could restore the defect (P < .001). With 40% GBL, a significant difference was identified (P = .001), as most coracoid grafts still provided adequate restoration (congruent arc Latarjet, 82.7%; traditional Latarjet, 76.9%), but distal clavicle grafts were markedly reduced, with only 51.9% of grafts maintaining sufficient dimensions. CONCLUSIONS The coracoid and distal clavicle grafts reliably restored up to 30% GBL in nearly all patients. The coracoid was the only graft that could reliably restore up to 40% GBL. CLINICAL RELEVANCE With "subcritical" GBL (>13.5%), all autologous bone grafts can be used to adequately restore the bony defect. However, with "critical" GBL (≥20%), only the coracoid and distal clavicle can reliably restore the bony defect.

Abstract
BACKGROUND The Latarjet procedure involves initial dissection through a longitudinal split of the subscapularis tendon with only a final partial closure to accommodate the transferred coracoid bone. Furthermore, by transferring the coracoid bone block to the anterior glenoid, the surgeon completely alters the resting and dynamic route of the attached conjoint tendon. The eventual structural and functional integrity of the subscapularis and conjoint tendons is currently unknown. PURPOSE To examine the structural and functional integrity of the subscapularis and the conjoint tendon after the Latarjet procedure at an 8-year average follow-up. STUDY DESIGN Case series; Level of evidence, 4. METHODS Twenty patients with anterior shoulder instability at a mean age of 30 years (range, 19-50 years) underwent the open Latarjet procedure. Clinical examination at the final follow-up included quantitative isometric measurement of abduction and internal rotation strength compared with the nonoperative side. Patients were assessed via radiograph examination and preoperative computed tomography. Final position and healing of the transferred coracoid bone block were evaluated using standard radiographs. At follow-up, the subscapularis and conjoint tendon were evaluated via magnetic resonance imaging (MRI) with metal artifact reduction techniques and via ultrasound. RESULTS Nineteen of the 20 shoulders remained stable at the final follow-up; there was 1 redislocation (5%) after 14 months. The mean Rowe score was 83 points (SD, 17.9 points), the mean Constant score was 85 points (SD, 8.1 points), and the Subjective Shoulder Value was 80% (SD, 18%). The mean abduction strength of the operative shoulder was 7.41 ± 2.06 kg compared with 8.33 ± 2.53 kg for the nonoperative side (P = .02). The mean internal rotation strength at 0° for the operative shoulder was 8.82 ± 3.47 kg compared with 9.06 ± 3.01 kg for the nonoperative side (P = .36). The mean internal rotation strength in the belly-press position for the operative shoulder was 8.12 ± 2.89 kg compared with 8.50 ± 3.03 kg (P = .13). Four of 20 shoulders showed mild tendinopathic changes of the subscapularis tendon but no partial or complete tear. One patient exhibited fatty degeneration Goutallier stage 1. Conjoint tendon was in continuity in all 20 shoulders on MRI scans. CONCLUSION Abduction, but not internal rotation strength, was slightly reduced after the Latarjet procedure at a mean of 8 years of follow-up. The subscapularis tendon was intact based on ultrasound examination, and the conjoint tendon was intact based on MRI scans. Subscapularis muscle girth relative to the supraspinatus muscle remained intact from preoperative measurements based on MRI scans.

Abstract
OBJECTIVE To evaluate the effectiveness of arthroscopic Pushlock anchor fixation with iliac creast bone autograft in the treatment of recurrent anterior shoulder instability with critical bone defect. METHODS The clinical data of 80 patients with recurrent anterior shoulder instability with critical bone defect treated by arthroscopic Pushlock anchor fixation with iliac creast bone autograft between January 2016 and January 2019 were retrospectively analyzed. The patients were all male; they were 18-45 years old at the surgery, with an average of 25 years old. The disease duration ranged from 3 months to 5 years, with an average of 2 years. The shoulder joint dislocated 3-50 times, with an average of 8 times. X-ray films, MRI, CT scans and three-dimensional reconstruction of the shoulder were performed before operation. The area of the anterior glenoid defect was 25%-45%, with an average of 27.3%. The shoulder mobility (forward flexion and external rotation in abduction at 90°), the Constant-Murley score, and the Rowe score were used to evaluate the shoulder function before operation and at last follow-up. RESULTS Patients were followed up 1-3 years, with an average of 2 years. No shoulder dislocation occurred again during follow-up. All partial graft absorption occurred after operation, CT scan showed that the graft absorption ratio was less than 30% at 1 week and 3 months after operation. CT three-dimensional reconstruction at 1 year after operation showed that all grafts had healed to the glenoid. The anterior glenoid bone defect was less than 5% (from 0 to 5%, with an average of 3.2%). At last follow-up, the shoulder mobility (forward flexion and external rotation in abduction at 90°), the Constant-Murley score, and the Rowe score significantly improved when compared with preoperative ones ( P<0.05). The shoulder mobility of external rotation in abduction at 90° of the affected side limited when compared with the healthy side [(6.7±5.1)°]. CONCLUSION Arthroscopic Pushlock anchor fixation with iliac creast bone autograft has a good effectiveness in the treatment of recurrent anterior shoulder instability with critical bone defect. The method is relatively simple and the learning curve is short.

Abstract
BACKGROUND While 2 screws are traditionally used for coracoid bone block fixation, no gold standard technique has yet been established when using cortical buttons. PURPOSE To compare anatomic and clinical outcomes of the arthroscopic Latarjet procedure using either 2 or 4 buttons for coracoid bone block fixation. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS A total of 23 patients with 4-button fixation (group 4B) were matched for age at surgery, sex, and follow-up to 46 patients who had 2-button fixation (group 2B). All patients underwent guided arthroscopic Latarjet (using coracoid and glenoid guides), and a tensioning device was used to rigidify the suture button construct and get intraoperative bone block compression. The primary outcome was assessment of bone block positioning and healing using computed tomography scans performed at 2 weeks and at least 6 months after surgery. The mean ± standard deviation follow-up was 49 ± 7 months (range, 24-64 months). RESULTS The bone block healing rate was similar in both groups: 91% in group 4B versus 95.5% in group 2B. The transferred coracoid was flush to the glenoid surface in 21 patients (91%) in group 4B and 44 patients (96%) in group 2B (P = .6); it was under the equator in 22 patients (96%) in group 4B and 44 patients (96%) in group 2B (P≥ .99). There was no secondary bone block displacement; the rate of bone block resorption was similar between the groups: 28% in group 4B and 23% in group 2B (P = .71). Patient-reported outcomes, return to sports, and satisfaction were also similar between the groups. The operating time was significantly longer in group 4B (95 vs 75 minutes; P = .009). CONCLUSION A 4-button fixation technique did not demonstrate any anatomic or clinical advantages when compared with a 2-button fixation technique, while making the procedure more complex and lengthening the operating time by 20 minutes. A 2-button fixation is simple, safe, and sufficient to solidly fix the transferred coracoid bone block. The use of drill guides allows accurate graft placement, while the use of a tensioning device to rigidify the suture button construct provides high rates of bone block healing with both techniques (>90%).

Abstract
PURPOSE To systematically review and compare the surgical indications, technique, perioperative treatment, outcomes measures, and how recurrence of instability was reported and defined after coracoid transfer procedures. METHODS A systematic review of the literature examining open coracoid transfer outcomes was conducted according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines using the Cochrane registry, MEDLINE, and EMBASE databases from 2010 to 2020. Inclusion criteria included open coracoid transfer techniques, including the Bristow or Latarjet technique, full text availability, human studies, and English language. RESULTS A screen of 1,096 coracoid transfer studies yielded 72 studies, which met inclusion criteria with a total of 4,312 shoulders. One study was a randomized controlled trial, but the majority of them were retrospective. Of those, 65 studies reported on postoperative outcome scores, complication rates, revision rate, and recurrence rates. Forty-three reported on range of motion results. Thirty studies reported on primary coracoid transfer only, 7 on revision only, and 30 on both primary and revision, with 5 not reporting. Average follow-up was 26.9 months (range: 1-316.8 months). Indications for coracoid transfer, technique, perioperative care, complications, and how failure was reported varied greatly among studies. CONCLUSIONS Latarjet and coracoid transfer surgery varies greatly in its indications, technique, and postoperative care. Further, there is great variation in reporting of complications, as well as recurrence and failure and how it is defined. Although coracoid transfer is a successful treatment with a long history, greater consistency regarding these factors is essential for appropriate patient education and surgeon knowledge. LEVEL OF EVIDENCE Level IV, systematic review of Level I-IV studies.

Abstract
Background. The shoulder joint is the one most amenable to dislocation. Dislocation of the humeral head is complicated by combined injuries of the shoulder joint, and if the patient does not seek treatment on the first day after the dislocation, irreversible changes in bone and soft tissue structures are formed.The aim of this review was to analyze modern methods of diagnosis and treatment of patients with defects in the articular surfaces of the scapula and humerus head with chronic shoulder dislocations.Material and methods. To search for literature data, we used the electronic databases MEDLINE, PudMed, eLIBRARY with a selection of sources published from 2000 to 2020. The analysis was carried out on works devoted to the diagnosis, surgical treatment and complications of traumatic shoulder dislocations.Results. When analyzing the literature on the surgical treatment of shoulder dislocations, we did not find clear criteria for planning the extent of surgery. The obtained results of surgical treatment testify to well-studied technologies for treating osteochondral defects of the humeral head up to 25 % of its total area. In the presence of a defect of 50 % of humeral head area or more, satisfactory results are shown when carrying out arthroplasty of the joint using a reverse endoprosthesis. However, the treatment of defects ranging in size from 25 to 50 % is still an unexplored problem. There are single techniques using allografts, mainly in English-speaking countries and, to a lesser extent, on the territory of the Russian Federation. Thus, the search for an algorithm for choosing a surgical treatment based on multi-layer spiral computed tomography and/or magnetic resonance imaging data, and the development of a new method of surgical treatment taking into account the obtained data are priority areas in modern traumatology and orthopedics.

Abstract
BACKGROUND The Latarjet is a successful procedure but can be associated with significant complications, including failure. Iliac crest bone grafting (ICBG) is one of the salvage options for such failure. PURPOSE To analyze factors associated with failure or success to restore shoulder stability with ICBG after Latarjet failure. STUDY DESIGN Case series; Level of evidence, 4. METHODS Twenty consecutive patients with recurrence of instability after a Latarjet procedure underwent revision using ICBG. Sixteen patients (80%) with a mean age of 35.0 years (range, 25-55) could be personally reexamined clinically and radiographically (including computed tomography scan) after a mean follow-up of 4.5 years (range, 2-8). Twelve patients had redislocation and 4 had recurrent subluxation after the Latarjet. RESULTS Salvage ICBG failed in 7 patients because of recurrent dislocations, with 5 necessitating reoperations: 2 arthrodeses, 1 reverse total shoulder arthroplasty, 1 repeat ICBG, and 1 Hill-Sachs allograft reconstruction and Bankart repair. Factors associated with ICBG failure were multidirectional instability (n = 2), subscapularis insufficiency (n = 1), uncontrolled seizures (n = 1), static inferior glenohumeral subluxation (n = 1), total graft resorption (n = 1), and voluntary dislocation attributed to schizoaffective disorder (n = 1). The initial Latarjet graft was malpositioned (too medial) in 3 of these patients. In patients without recurrent instability (n = 9), reasons for Latarjet failure were graft related: 6 graft avulsions, 2 graft resorptions, and 1 medial graft malpositioning. The mean absolute Constant score (62 to 87 points, P = .012) and relative Constant score (66% to 91%, P = .012), pain (10 to 15 points, P < .001), and Subjective Shoulder Value (31% to 85%, P = .011) in the group with a successful procedure were significantly improved over the preoperative state, and the total Western Ontario Shoulder Instability Index averaged 64% at final follow-up. Except in 1 case of major resorption, mild graft resorption or none was observed in successful procedures. Axial and sagittal graft positioning was good in all 9 patients. CONCLUSIONS Salvage ICBG for failed Latarjet procedures failed in 7 of 16 patients. It was successful in patients with clearly graft-related factors of the initial Latarjet procedure. However, patients with unclear instability symptoms, subscapularis insufficiency, inferior subluxation, uncontrolled seizures, or psychological disorders were poor candidates for salvage ICBG, underlining the importance of careful patient selection for the initial Latarjet procedure and for salvage ICBG.

Abstract
Arthroscopic distal clavicular autograft (DCA) is effective in shoulder instability with glenoid bone loss. The original technique uses an osteochondral autograft, fixed with screws or suture anchors. We developed a modified procedure called "congruent arc DCA" characterized by (1) use of drilling guides to optimize graft positioning and make the all-arthroscopic procedure safer and reproducible; (2) rotation of the DCA of 90° to reach a congruent arc with its undersurface; (3) fixation of the graft with cortical buttons to simplify its intra-articular passage, avoid hardware problems, and facilitate possible revision surgery; and (4) intraoperative use of a suture tensioner to achieve satisfactory compression of the graft and increase its consolidation.

Abstract
Background Anterior shoulder dislocation remains a clinical challenge. This study aimed to assess the graft position and clinical outcomes of the arthroscopic Latarjet procedure and capsular repair for the treatment of recurrent anterior shoulder dislocation with significant glenoid bone loss in 37 patients. Methods Between 2017 and 2017, 37 patients underwent arthroscopic Latarjet plus capsular repair procedure for recurrent anterior shoulder dislocation combined with significant glenoid bone loss. In follow-up examinations, Walch-Duplay scores, subjective shoulder value (SSV) scores, Rowe scores, and active range of motion (AROM) were assessed. Three-dimensional computed tomography (CT) was used to evaluate coracoid graft position and bone resorption. A new method of evaluating the position of the coracoid bone block after Latarjet (H-Z method) was developed. Results Thirty-seven patients were included in this study. Follow-up ranged from 6 to 36 months postoperatively (with an average of 13 months). No recurrent dislocation occurred at the final follow-up, and there was no significant effect on the AROM (all p > 0.05). Rowe (from 42.2 ± 5.6 to 91.1 ± 3.3), Walch-Duplay (from 31.5 ± 8.0 to 92.6 ± 3.7), and SSV (from 63.9 ± 6.1 to 79.3% ± 5.0%) scores were improved significantly after surgery (all p < 0.001). CT showed that the 29 patients had varying degrees of bone resorption, and 23 recovered to the preinjury level of motional function within 6–12 months after surgery. Conclusions In active patients with recurrent anterior shoulder dislocations and significant glenoid bone loss, the arthroscopic Latarjet procedure plus capsular repair could restore shoulder stability satisfactory.

Intra-articular biomechanical environment following modified Bristow and Latarjet procedures in shoulders with large glenoid defects: relationship with postoperative complications. J Shoulder Elbow Surg 2021; 30:2260-2269.

Abstract
BACKGROUND Although coracoid transfers including the modified Bristow and Latarjet procedures are widely used to treat anterior shoulder instability, the influence of the choice of procedure on the biomechanical outcomes is not well characterized. We aimed to clarify the intra-articular stress distribution following these 2 procedures using 3-dimensional finite-element analysis and to investigate the role of stress distribution in the pathophysiology of postoperative complications. METHODS Overall, 6 male patients aged 17-47 years with unilateral anterior shoulder instability were recruited. Computed tomographic digital imaging and communications in medicine (CT-DICOM) data of the contralateral (healthy) shoulder of each patient was obtained and used for developing the 3-dimensional normal glenohumeral joint model. A 25% bony defect was created in the anterior glenoid rim where the coracoid process was transferred in the standing and lying-down positions to create the Bristow and Latarjet models, respectively. The arm position was set as 0° or 90° abduction. The Young moduli of the humerus and scapula were calculated using CT data, and set as 35.0 MPa and 113.8 GPa for the articular cartilage and inserted screw, respectively. A compressive load (50 N) was applied to the greater tuberosity toward the center of the glenoid, and a tensile load (20 N) was applied to the tip of the coracoid in the direction of conjoint tendon. Elastic analysis was used to determine the equivalent stress distribution. RESULTS A significant reduction in mean equivalent stress was observed within the glenoid cartilage for both models (P = .031); however, a new stress concentration appeared within the grafted coracoid-facing region of the humeral-head cartilage in both models. The proximal half of the coracoid graft exhibited lower equivalent stress than the distal half in 5 of the 6 Latarjet models, whereas the proximal half showed higher equivalent stress than the distal half in all 6 Bristow models. High stress concentration was identified at the midpoint of the inserted screw in Bristow models. DISCUSSION AND CONCLUSIONS Intra-articular stress distribution may explain the different rates of postoperative complications associated with the modified Bristow and Latarjet procedures. New stress concentration within the humeral-head cartilage might contribute to the development of glenohumeral osteoarthritis following both procedures. Stress shielding in the proximal part of the coracoid graft might contribute to osteolysis following the Latarjet procedure. Surgeons should be aware of the risk of breakage of the inserted screw following the modified Bristow procedure.

[PMID: 33581303 DOI: 10.1016/j.arthro.2021.01.061] [Citation(s) in RCA: 20] [Impact Index Per Article: 6.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/18/2020] [Revised: 01/26/2021] [Accepted: 01/27/2021] [Indexed: 02/02/2023]
Abstract
PURPOSE The purpose of our study is to prove that the autologous scapular spine bone graft is an alternative for the treatment of anterior shoulder instability and the clinical and radiological results are promising. METHOD From July 2016 to August 2018, patients who were diagnosed as having anterior shoulder instability with subcritical (10%-15%) glenoid bone loss were treated by arthroscopic repair with autologous scapular spine bone graft. The inclusion criteria were (1) anterior shoulder instability underwent arthroscopic autologous scapular spine bone graft; (2) glenoid bone loss was within 10% to 15% (measured by Sugaya's method); (3) three complete sets of computed tomography (CT) scans (preoperative, 1 week after surgery, and 1 year after surgery) available; and (4) clinical follow-up time was at least 2 years. The exclusion criteria were (1) concomitant rotator cuff tear; (2) concomitant remplissage or SLAP repair; (3) previous surgery of the affected shoulder; (4) open surgery; and (5) incomplete radiological or clinical follow-up. The preoperative and postoperative Constant-Murley score, dietary approaches to stop hypertension (DASH) score, visual analog scale (VAS) score, and range of motion (ROM) were recorded. CT scans with 3-dimensional reconstruction were obtained at the first week after operation and at 1 year after operation; the graft resorption rate was consequently calculated. RESULTS Twenty-seven patients were qualified and enrolled in the study. No severe complication was recorded during follow-up. No redislocation or subluxation was found, and the apprehension tests were all negative. At the last follow-up, the mean Constant-Murley score was 89.74 ± 3.71, the mean DASH score was 9.77 ± 5.31, the mean VAS score was 0.74 ± 0.64, which are all improved significantly compared with preoperative scores (P = .00,.00,.00, respectively). At the last follow-up, the ROM including anterior flexion, external rotation by side, and the internal rotation were well restored without significant difference compared with the contralateral shoulder (P =.48, .08, .47, respectively). At 1 year after operation, the resorption rate of the bone graft was 19.4%. CONCLUSION This study found that anterior shoulder instability with subcritical (10%-15%) glenoid bone loss treated with arthroscopic autologous scapular spine bone graft with suture anchor fixation is safe and could achieve satisfactory result at short-term follow-up. LEVEL OF EVIDENCE Therapeutic case series.

Computed Tomography-Based Preoperative Planning Provides a Pathology and Morphology-Specific Approach to Glenohumeral Instability With Bone Loss. Arthroscopy 2021; 37:1757-1766.e2. [PMID: 33515735 DOI: 10.1016/j.arthro.2021.01.021] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/09/2020] [Revised: 12/31/2020] [Accepted: 01/04/2021] [Indexed: 02/02/2023]
Abstract
PURPOSE To use computed tomography (CT) to determine a reproducible method of coracoid measurement to compare the ability of the classic Latarjet technique and the congruent arc modification (CAM) to restore native glenoid diameter and to develop a preoperative planning algorithm for glenoid restoration with a goal of achieving an on-track shoulder. METHODS Coracoid dimensions were measured on multiplanar reconstructed shoulder CT scans of patients aged 18 to 45 years obtained between December 1, 2019, and March 13, 2020. Patients were excluded if CT demonstrated osteophyte formation, glenoid dysplasia, coracoid fracture, or tumor. The proportion of glenoid diameter able to be restored using classic Latarjet technique and CAM were calculated. A treatment algorithm was proposed considering the amount of bone loss present and coracoid dimensions. RESULTS Coracoid dimensions of 117 consecutive patients were measured and varied considerably (length: 17.5-31.8 mm, width: 9.1-20.5 mm, thickness: 6.1-15.7 mm). While most patients had harvestable coracoid length ≥20 mm (male: 96.3% vs female: 94.4%, P = .65), only 27.8% of female patients had coracoid thickness ≥10 mm. When comparing Latarjet techniques, there was no difference in the proportion of patients in whom 30% glenoid diameter could be fully restored, but CAM was able to restore at least 35% in more male and female patients (98.8% vs 79.0% and 100% vs 61.1%, respectively, P = .00001). Intra- and inter-rater reliability was excellent ( intraclass correlation coefficient ≥0.950 for all dimensions). CONCLUSIONS We describe a reliable method of measuring coracoid dimensions for preoperative planning of glenoid restoration. The classic Latarjet technique reliably restores the glenoid anteroposterior diameter with bone loss of up to 30%. The majority of female patients have coracoid thickness <10 mm, which may increase the risk of graft fracture when using CAM. The decision to use the classic Latarjet technique or CAM considers each individual's glenoid and coracoid dimensions with a goal of achieving an on-track shoulder. CLINICAL RELEVANCE Our reliable method of coracoid measurement demonstrated the differing abilities of the classic Latarjet and CAM to restore the native glenoid diameter. An evidence-based algorithm using these measurements was developed to assist in preoperative planning for glenohumeral instability in the setting of bone loss, with a goal of achieving an on-track shoulder. Alternative techniques may be considered if an on-track shoulder cannot be achieved with Latarjet.

Abstract
BACKGROUND Recently, arthroscopic double-button Latarjet (AL) has provided an alternative to conventional open Latarjet (OL) in the treatment of anterior shoulder instability with glenoid bone loss. Therefore, theoretically, the faster fusion is obtained, the sooner return to sports under safe conditions can occur. The emerging flexible fixation of the bone block has clearly offered a new approach to achieve bone fusion. However, the period required to achieve this goal remains controversial. PURPOSE/HYPOTHESIS The purpose was to compare computed tomography (CT) scan results of AL and OL in the early postoperative period. It was hypothesized that the bone block fusion with AL would require a longer time than that with OL. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS In a retrospective 1-year study, the authors compared 17 primary double-button AL to 22 primary 2-screw OL procedures indicated for anterior shoulder instability in patients with an Index Severity Instability Score >3 points. These patients were reviewed with a CT scan at 1 day, 3 months, and 6 months postoperatively. The characteristics for the 2 groups were comparable. CT scans aimed to analyze graft position, bone contact area with the scapula, and fusion at 3 and 6 months. Clinical assessment was based on the Walch-Duplay and Rowe scores. RESULTS The mean preoperative Index Severity Instability Score was 5.3 ± 1.9 points, with a mean anterior glenoid bone loss of 9.1% ± 4.6%. At 3 months, the rates of fusion were 41% and 100% for the AL and OL groups, respectively (P < .001). This rate increased to 70% in the AL group at 6 months (P = .006). In the axial and sagittal planes, there was no difference in graft position between the AL group and the OL group. The bone block was longer and there was a more extensive bone contact area in the OL group (AL, 131 mm2 vs OL, 223 mm2; P < .001). At 6 months of follow-up, no significant difference in clinical scores was noted between the groups: Walch-Duplay score, 93.0 ± 10.9 points versus 91.8 ± 12.5 points (P = .867); and Rowe score, 99.0 ± 2.2 points versus 95.0 ± 8.4 points (P = .307) for the AL and OL groups, respectively. CONCLUSION AL required more time to achieve bone block fusion than OL. This finding should be taken into account when considering this procedure for patients in a hurry to return to sports involving the shoulder.

EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY AND TRAUMATOLOGY 2021; 32:279-286. [PMID: 33818639 DOI: 10.1007/s00590-021-02965-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/22/2021] [Accepted: 03/23/2021] [Indexed: 11/24/2022]
Abstract
PURPOSE The primary aim of this study is to prove that reconstructing the anterior glenoid defect with iliac crest graft arthroscopically using double-barrelled cannula through the rotator interval is safe and prevents both recurrence of instability and the neurovascular injury because subscapularis muscle is not split and procedure is far away from important structures. METHODS Thirteen patients with anterior shoulder instability and engaging Hill-Sachs lesion were reviewed after arthroscopic reconstruction of the anterior glenoid with iliac crest autogenous graft. Patient satisfaction and Western Ontario İnstability Score (WOSI) were evaluated on clinical examination. Computed tomography was used to analyse graft position on sagittal and axial planes. RESULTS The mean follow-up was 28.7 months (SD 7.1), and age at surgery was 31 years (21 to 64 years). Post-operatively there was only one dislocation due to trauma. There was statistically significant improvement of WOSI scores (p: 0.001). There was not any neurological injury. Graft position on the axial plane was described as flush in 5 cases (41%), lateral in 2 (16%), too lateral in one (8%) and medial in 4 of the cases (33%). Graft position could be accepted as high in only three patients (23%). CONCLUSION Arthroscopic reconstruction of glenoid defect using autogenous iliac bone graft, through rotator interval, without splitting subscapularis is safe and effective without any neurological injury, producing substantial graft position and good functional outcomes in patients.

Abstract
The congruent-arc Latarjet (CAL) allows reconstruction of a greater percentage of glenoid bone deficit because the inferior surface of the coracoid is wider than the lateral edge of the coracoid used with the traditional Latarjet (TL). Biomechanical studies have shown higher initial fixation strength between the graft and the glenoid with the TL. In the TL, the undersurface of the coracoid, which is wider than the medial edge used with the CAL, remains in contact with the anterior edge of the glenoid, increasing the contact surface between both bones and thus facilitating bone consolidation. The shorter bone distance around the screw with the CAL is potentially less tolerant of screw-positioning error compared to the TL. Moreover, the wall of the screw tunnel is potentially more likely to fracture with the CAL due to the minimal space between the screw and the graft wall. CAL may be very difficult to perform in patients with very small coracoids such as small women or skeletally immature patients. Radius of curvature of the inferior face of the coracoid graft (used with the CAL) is similar to that of the native glenoid. This may potentially decrease contact pressure across the glenohumeral joint, avoiding degenerative changes in the long term.

Abstract
PURPOSE To evaluate the clinical, functional, and radiological midterm outcomes of the all-arthroscopic modified Eden-Hybinette procedure in patients with recurrent anterior shoulder instability. METHODS A retrospective, single-center case series with prospectively collected data was conducted. The inclusion criterion was traumatic recurrent anterior shoulder instability with significant glenoid bone loss; patients with atraumatic or multidirectional instability were excluded. An all-arthroscopic modified Eden-Hybinette procedure using iliac crest autograft and double-pair button fixation was carried out. All patients were postoperatively assessed for recurrence and apprehension. Shoulder range of motion values and functional scores, including American Shoulder and Elbow Surgeons Score, Oxford instability, Rowe instability, and Walch-Dupplay, were recorded. Graft positions, healing, and absorption were evaluated with computed tomography. Comparisons of values were performed with paired t tests for normally distributed differences and with nonparametric Wilcoxon's signed rank test otherwise. RESULTS The final study cohort included 28 patients, mean age 36 ± 10 years, and mean follow-up period 43 ± 6 months (range 36 to 53). Median glenoid bone loss was 12.4% (range 8% to 33%). No recurrence occurred, no subjective shoulder instability was reported, and no major complications were documented through the last follow-up. Postoperative shoulder range of motion had no significant differences compared with the healthy side. All final postoperative functional scores significantly increased to show excellent results compared with preoperative values. All grafts were positioned and healed optimally, and none was completely reabsorbed. CONCLUSIONS The all-arthroscopic modified Eden-Hybinette procedure is safe, leading to excellent clinical and radiological midterm outcomes in patients with recurrent anterior shoulder instability. This technique restores glenoid bone defects and preserves the normal shoulder anatomy. LEVEL OF EVIDENCE IV, therapeutic, retrospective case series.

Abstract
PURPOSE To evaluate the clinical and radiologic outcomes of patients undergoing arthroscopic glenoid bone allograft combined with subscapularis upper-third tenodesis for anterior shoulder instability associated with clinically relevant bone loss and hyperlaxity. METHODS Between January 2016 and December 2017, patients with recurrent anterior shoulder instability associated with bone loss and hyperlaxity were selected and treated with arthroscopic iliac crest bone graft combined with subscapularis upper-third tenodesis. The selection criteria were as follows: more than 5 dislocations; positive apprehension, anterior drawer, and Coudane-Walch test results; glenoid bone defect between 15% and 30% and humeral bone defect with an engaging Hill-Sachs lesion; and no previous shoulder surgery. All patients were followed up with the Constant score, University of California-Los Angeles (UCLA) rating, Rowe score, and visual analog scale evaluation. Assessments were performed with plain radiographs and a PICO computed tomography scan before surgery and at 2 years of follow-up. RESULTS Nineteen patients were included in the study, with a mean follow-up duration of 34.6 months (range, 24-48 months). In 17 patients (89%), excellent clinical results were recorded according to the Rowe score. The Constant score improved from 82.9 (standard deviation [SD], 5.2) to 88.9 (SD, 4.3) (P = .002); Rowe score, from 25.3 (SD, 5.3) to 89.1 (SD, 21.8) (P < .001); UCLA score, from 23.7 (SD, 3) to 31.5 (SD, 4.8) (P < .001); and visual analog scale score, from 3.2 to 1.3 (P < .001). Patients met the minimal clinically important difference 94.7%, 89.5%, and 47.3% of the time for the Rowe score, UCLA score, and Constant score, respectively. Bone graft resorption was observed in all patients: partial in 9 and complete in 10. We recorded 2 recurrent traumatic dislocations (11%), with no case of persistent anterior apprehension or other complication. CONCLUSIONS An arthroscopic glenoid bone graft combined with subscapularis upper-third tenodesis may be a valid surgical option to treat recurrent anterior instability associated with both bone loss and hyperlaxity.

Abstract
Background Management of failed anterior stabilization is difficult. There are two main options for revision either a revision labral repair which has published high failure rates because of poor quality capsulolabral tissues or a bone block/Latarjet procedure with associated morbidity and complication rates. On this background, the senior author (D.T.) has developed a new procedure to treat this difficult to manage clinical scenario. Aim The aim of this study was to evaluate the 2-year results of an arthroscopic conjoint tendon transfer procedure. The procedure has previously been developed to provide a potential solution for active patients with a failed labral repair, subcritical glenoid bone loss, and an on-track Hill-Sachs lesion. Methods Consecutive patients who fulfilled the inclusion criteria were prospectively recruited. Inclusion criteria were active patients with recurrent shoulder instability owing to failed labral repair, less than 10% anterior glenoid bone loss, and an on-track Hill Sachs lesion. Patients were fully consented and offered a choice of revision with an arthroscopic labral repair, a Latarjet procedure or the arthroscopic conjoint tendon transfer procedure. Preoperative and postoperative Western Ontario Shoulder Instability Index and Oxford Instability Score were collected. Results Eight patients met the inclusion criteria and opted for the conjoint tendon transfer procedure. Mean age was 35 with a male:female ratio of 7:1. No patients had hyperlaxity clinically. At median follow-up of 31 months (range 24-41), there was a significant improvement in both the median Western Ontario Shoulder Instability Index (53.7 to 13.4, P = .0003) and Oxford Instability Score (27 to 44.5, P = .0017) scores. No patient had a further dislocation, and all were able to resume contact and noncontact sports. Conclusion Our results at a minimum of 2-year follow-up demonstrate that the arthroscopic transfer of the conjoint tendon confers clinical stability in patients with a failed primary labral repair who have minimal bone loss.

Abstract
The rate of recurrence of anterior unidirectional instability is lower after coracoid bone-block than with other techniques, even if failures still occur with this difficult procedure. Failure may consist in recurrent instability (dislocation, subluxation, unstable painful shoulder) or despite absence of obvious clinical signs, in radiologic failure (non-union, fracture), biologic failure (osteolysis) or infection, all of which may require revision surgery or lead to late instability or subclinical chronic apprehension. Clinical, X-ray and CT assessment identifies the type of failure and may lead to a second surgery being discussed with the patient according to functional demand. Technical error is often implicated and is generally due to deficient coracoid preparation, insufficient conjoint and coracoid tendon release or problems of positioning and fixing the bone-block on the glenoid. There are 2 types of revision surgery. Iliac bone-block involves the same demands as coracoid bone-block; it stabilises the shoulder and provides very good functional results. Although less effective, anterior capsule repair can also stabilise the shoulder when associated to posterior Hill-Sachs lesion remplissage by infraspinatus tenodesis. Osteoarthritis of the shoulder may set in after any surgical revision and impair the result.

Abstract
Background Posterior shoulder instability is uncommon, and its treatment is a challenging problem. An arthroscopically assisted technique for posterior iliac crest bone grafting (ICBG) has shown promising short- and long-term clinical results. Changes as shown on imaging scans after posterior ICBG for posterior shoulder instability have not been investigated in the recent literature. Purpose To evaluate changes on computed tomography (CT) after arthroscopically assisted posterior ICBG and to assess clinical outcomes. Study Design Case series; Level of evidence, 4. Methods Patients with preoperative CT scans and at least 2 postoperative CT scans with a minimum follow-up of 2 years were included in the evaluation. Of 49 initial patients, 17 (follow-up rate, 35%) met the inclusion criteria and were available for follow-up. We measured the glenoid version angle and the glenohumeral and scapulohumeral indices on the preoperative CT scans and compared them with measurements on the postoperative CT scans. Postoperatively, graft surface, resorption, and defect coverage were measured and compared with those at early follow-up (within 16 months) and final follow-up (mean ± SD, 6.6 ± 2.8 years). Results The mean preoperative glenoid version was -17° ± 13.5°, which was corrected to -9.9° ± 11.9° at final follow-up (P < .001). The humeral head was able to be recentered and reached normal values as indicated by the glenohumeral index (51.8% ± 6%; P = .042) and scapulohumeral index (59.6% ± 10.2%; P < .001) at final follow-up. Graft surface area decreased over the follow-up period, from 24% ± 9% of the glenoid surface at early follow-up to 17% ± 10% at final follow-up (P < .001). All clinical outcome scores had improved significantly. Progression of osteoarthritis was observed in 47% of the shoulders. Conclusion Arthroscopically assisted posterior ICBG restored reliable parameters as shown on CT scans, especially glenoid version and the posterior subluxation indices. Graft resorption was common and could be observed in all shoulders. Patient-reported clinical outcome scores were improved. Osteoarthritis progression in almost 50% of patients is concerning for the long-term success of this procedure.

Abstract
Massive glenoid bone loss in recurrent anterior instability of the shoulder represents a surgical challenge. Some clinical trials have been published assessing the role of arthroscopic iliac crest bone grafting techniques for the management of recurrent anterior instability with glenoid bone loss. However, bone graft fixation is still controversial. We developed a method for anatomic reconstruction of anterior glenoid bone defects using autologous iliac crest graft. This technique is based on the assumption that anatomic restoration of glenoid depth and width is essential to restore stability to the shoulder.

Abstract
BACKGROUND The prevalence of nonunion after the Latarjet procedure remains high. The purpose of the present study was to investigate healing and clinical outcomes after a novel arthroscopic coracoid process transfer procedure. METHODS Sixty-three patients who underwent the arthroscopic inlay Bristow procedure combined with Bankart repair were identified, and 51 patients who met the inclusion criteria were enrolled in this study. The key feature of this technique was that the coracoid process was trimmed and fixed into a trough (5 to 10 mm deep) in the glenoid neck with a metal screw. Bone graft union and positioning accuracy were assessed with use of postoperative computed tomography (CT) imaging. Clinical examinations, return to sport, and functional scores (American Shoulder and Elbow Surgeons [ASES] and Rowe scores) were recorded. RESULTS The mean duration of follow-up (and standard deviation) was 41.5 ± 7.7 months (range, 36 to 48 months). Postoperative CT scans showed that the position of coracoid graft was at 4:10 (from 3:50 to 5:00) (referencing the right shoulder) in the sagittal view. The α angle was 16.4° ± 9.5°, with 4 (7.8%) of 51 screws being over-angulated (α > 25°). On the axial view, the graft position was considered to be flush in 33 patients (64.7%), medial in 11 (21.6%), congruent in 7 (13.7%), and lateral or too medial in none. At 1 year, the coracoid graft had healed in 49 patients (96.1%) and had failed to unite in 2 patients. CT scanning, performed for 47 patients, showed grade-0 osteolysis in 9 patients, grade-1 osteolysis in 21 patients, and grade-2 osteolysis in 17 patients. At the time of the latest follow-up, there was a significant increase in the Rowe score (from 35.5 ± 8.3 to 95.7 ± 7.2) and the ASES score (from 71.2 ± 9.7 to 91.5 ± 4.4), and 87.0% of patients were able to return to sport. No arthropathy was observed in any patient. CONCLUSIONS After a minimum 3-year follow-up, the arthroscopic inlay Bristow procedure resulted in a high rate of graft healing, excellent clinical outcomes, and a high rate of return to sports. LEVEL OF EVIDENCE Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.
