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.

Suture Button Fixation in Latarjet Has Similar Load to Failure and Clinical Outcomes but Lower Bone Resorption Compared With Screw Fixation: A Systematic Review. Arthroscopy 2024; 40:1637-1654. [PMID: 37890545 DOI: 10.1016/j.arthro.2023.10.021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/25/2023] [Revised: 09/29/2023] [Accepted: 10/16/2023] [Indexed: 10/29/2023]
Abstract
PURPOSE To compare the 2 Latarjet fixation techniques-screw fixation (SF) versus suture button (SB) -for clinical, biomechanical, and radiologic outcomes. METHODS A systematic review was conducted in accordance with Preferred Reporting Items for Systematic and Meta-Analyses guidelines using MEDLINE and Embase databases and was prospectively registered on PROSPERO. Only comparative clinical and biomechanical studies of Latarjet with SF and SB were included. Studies were appraised using the Methodical Index for Non-Randomised Studies (MINORS) tool. RESULTS Eleven studies met eligible criteria: 7 clinical studies (SB, n = 279; SF, n = 845) and 4 biomechanical. In total, 80.9% (SB) and 84.2% (SF) of patients were male. Follow-up ranged from 6 to 63.6 months. The overall recurrent instability rate for SB ranged from 0 to 8.3% and for SF ranged from 0 to 2.75%. Only one study demonstrated a greater recurrent instability rate with SB (P = .02). Overall SB complication rates ranged from 0 to 12.5% and SF ranged from 0 to 27%. Two studies reported greater complications and reoperations with SF related to hardware. Summary forest plots from 4 studies showed no significant difference in Walch Duplay score (mean difference, range -5.00 to 1.20 [95% confidence interval {CI} -12.13 to 8.56], I2 inconsistency = 0%), Rowe score (mean difference, range -2.00 to 4.00 [95% CI -7.37 to 7.66], I2 inconsistency = 45%), and VAS for pain (mean difference, range -0.10 to 0.60 [95% CI -0.72 to 1.33], I2 inconsistency = 0%). There was no statistically significant difference between SB and SF in the postoperative range of motion. Radiologically, there was no significant difference in graft positioning and union at final follow-up, but graft resorption was greater in SF (range 25.2%-47.6%) compared with SB (range 10.1%-18.5%). Biomechanical studies showed no significant difference in maximum load to failure (SB, range 184-266 N vs SF, range 148-288 N). CONCLUSIONS Clinically, SB fixation demonstrated similar functional outcome and range of motion when compared with SF, with the potential benefit of lower rates of graft resorption and hardware-related complications. Biomechanically there was no difference in maximum load to failure. LEVEL OF EVIDENCE Level III, systematic review of Level III and biomechanical studies.

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
INTRODUCTION The arthroscopic bone block has shown reliability and reproducibility regarding functional scores and shoulder mobility compared to the open bone block technique. The recovery of muscle strength, especially the strength ratio external rotator/internal rotator (ER/IR), is crucial to recovering satisfactory function. This ratio should be as near to 1 as possible, meaning a good strength balance. Little is known about the difference in strength recovery between the open and arthroscopic techniques. HYPOTHESIS Arthroscopic Latarjet reduces surgical stress and improves the strength recovery and strength ratio. OBJECTIVES To compare arthroscopic and open Latarjet procedures for shoulder muscle strength and functional outcomes. MATERIAL AND METHODS It was an observational longitudinal and prospective cohort follow-up. Two groups of patients were accessible for comparison: 35 in an arthroscopy group and 38 in an open group. The main outcome was the muscle strength of shoulder muscles measured with a dynamometer and expressed in Newton (N) at day 21 (D21), D45, D90, D180, and D365 in the operated and contralateral shoulders. The measurements were made for the pectoralis major, the three deltoid fascicles, and the subscapularis. The shoulder ER/IR strength ratio was calculated. Other variables were the range of motion (ROM), the Walch-Duplay (WD), the Western Ontario Shoulder Instability score (WOSI), and the Visual Analogic Scale for pain assessment. The strength, ROM, and functional scores were compared between open and arthroscopy with linear mixed models. RESULTS The median strengths at 52 weeks were significantly higher than at 3 weeks (P<10-4): anterior deltoid (AD) 8N (Q1:7, Q3: 9) versus 4N (Q1:2, Q3: 5), lateral deltoid (LD) 9N (Q1:9, Q3: 11) versus 6N (Q1:4, Q3: 7), posterior deltoid (PD) 14N (Q1:12, Q3: 15) versus 9N (Q1:8, Q3: 10), subscapularis 10N (Q1:9, Q3: 12) versus 7N (Q1:5, Q3: 8), and pectoralis major (PM) 11N (Q1:9, Q3: 12) versus 7N (Q1:5, Q3: 10). The overall strengths were lower in the open group compared to the arthroscopy group: AD -2.1N (CI95%[-3.1--1.2], p=0.0005), LD -1.3N (CI95% [-2.4--0.15], p=0.03), PD -0.35N (CI95% [-1-0.9], p=0.52), subscapularis -2.1N (CI95% [-3.3--0.7], p=0.006), and PM -1.4N (CI95% [-2.2--0.02], p=0.03). The ER/IR ratio was stable throughout the follow-up for both the operated and contralateral shoulders (p>0.5). The overall mean ratio was 1.3 (median 1.2, Q1: 1, Q3:1.45) for the operated shoulder and 1.1 (median 1, Q1: 0.9, Q3:1.3) for the contralateral shoulder (p=0.0004). The average ER/IR ratio was 0.27 points higher in the open group (CI95% [0.1-0.46], p=0.003). The ROM was similar between the two groups, and there was no correlation between the ER/IR ratio and the ROM (p>0.5). The VAS < 3 weeks and WD > 12 weeks were significantly poorer in the open group: +0.61 (CI95% [0.03-1.16] p=0.02), and -7.3 points (CI95% [-13--0.01], p=0.05), on average, respectively. CONCLUSION The patients in the arthroscopy group had a better ER/IR strength ratio (closer to 1) and better WOSI after 12 weeks. The strength and the ROM were not correlated with each other.

Abstract
BACKGROUND Compared with the Latarjet procedure, the Bristow procedure has a lower screw-related complication rate but poor bone healing. A modified Inlay Bristow procedure has been reported to significantly improve the bone healing rate, but the biomechanical mechanism is unclear. The aim of this study was to evaluate the biomechanical stability of the bone graft between a modified Inlay Bristow procedure and the classic Bristow procedure. METHODS Sixteen left scapula models (Sawbones, Composite Scapula, and fourth generation) were randomly divided into 2 groups (8:8). The bone graft in the first group was fixed with a 3.5 mm screw using the Inlay structure. The bone graft in the second group was fixed with a 3.5 mm screw via the traditional method. The maximum cyclic displacement, ultimate failure load and stiffness were evaluated biomechanically. The failure type was recorded for each model. RESULTS Cyclic loading tests demonstrated that the maximum cyclic displacement of the Inlay procedure was significantly smaller (P = .001) than that of the classic procedure. The Inlay Bristow technique resulted in a significantly higher (P = .024) ultimate failure load than the classic Bristow technique. The stiffness of the classic group was 19.17 ± 4.01 N/mm and that of the inlay group was 22.34 ± 5.35 N/mm (P = .232). Failure was mainly due to bone graft fractures through the drill hole or glenoid bone fractures. CONCLUSION Inlay Bristow fixation of the bone graft in a Sawbones model provides significantly stronger fixation and better time point zero stability than classic Bristow fixation, suggesting a higher likelihood of graft union.

Abstract
BACKGROUND Few clinical studies have addressed concavity restoration by natural remodeling after a Latarjet procedure. This study investigated the fibrous tissue and osseous remodeling of the reconstructed glenoid and concavity restoration after a Latarjet procedure using postoperative computed tomographic arthrography (CTA). METHODS This retrospective study included 31 patients who underwent immediate postoperative computed tomographic (CT) scanning followed by CTA at 6 months postoperatively. We investigated whether fibrous tissue was newly created over the graft, whether the created fibrous tissue restored the congruity of the articular surface and the osseous remodeling of the graft to the glenoid level (whether the osseous portion of the graft was remodeled flush to the glenoid level) and the concavity of the glenoid using the radius of a best-fit circle on the articular surface, and the relationship between the amount of created fibrous tissue and the position of the graft. RESULTS In all patients, the fibrous tissue on the graft yielded a smooth articular surface, as revealed by the CTA. The mean radius of the entire glenoid, including the transferred graft, was significantly smaller (p = 0.010) at 33.2 ± 8.5 mm than that of the glenoid posterior to the osseous step-off at 37.6 ± 9.4 mm, which is presumed to be the glenoid before the surgical procedure. Despite the congruity of the articular surfaces due to fibrous tissue seen in the CTA, 14 (45%) of 31 patients showed a subchondral osseous step-off on either the medial side or the lateral side in the immediate postoperative CT scans. However, through osseous remodeling, 8 of the 10 grafts with a lateral step-off and 2 of the 4 grafts with a medial step-off converted to a flush position. The position of the step-off was correlated with the thickness of the fibrous tissue, with a tendency for thicker tissue in cases of a step-off on the medial side (p = 0.014). CONCLUSIONS Fibrous tissue formation plus remodeling of the transferred graft resulted in the restoration of a congruent concavity after a Latarjet procedure by compensating for initially non-flush positioning of the graft. However, due to the small sample size in our study, clinical outcomes could not be correlated with radiographic findings, and our recommendation is to continue placing the graft as anatomically as possible.

Abstract
Introduction Shoulder dislocation is the most common injury encountered in orthopedic outpatient department. The choice of procedure depends on the expertise of surgeons. The objective of this study was to compare the Latarjet procedure with the modified Putti-Platt surgery for recurrent anterior shoulder dislocation in terms of functional outcomes. Materials and methods A quasi-experimental study evaluated 60 patients with recurrent anterior shoulder instability. Patients were assigned to either Latarjet or modified Putti-Platt surgery. Functional outcomes were assessed at six months using the Constant-Murley shoulder score. Results This study encompassed 60 patients (mean age: 23.93±5.88 years) undergoing shoulder procedures. Functional outcomes exhibited a majority of 55% excellent, 35% good, 6.7% fair, and 3.3% poor outcomes. No significant differences in functional outcomes were found between the procedures. Conclusion Both procedures may be viable options for recurrent shoulder instability. The choice may depend on patient factors and surgeon preference. Further research is needed to refine techniques and identify ideal candidates.

Abstract
BACKGROUND There is a lack of consensus concerning the coracoid graft length in the modified Bristow procedure. OBJECTIVE We attempted to determine the optimal graft length using the three-dimensional finite element method. METHODS In a shoulder model with a 25% anterior glenoid defect, a coracoid graft of varying lengths (5, 10, 15, and 20 mm) was fixed using a half-threaded screw. First, a compressive load of 500 N was applied to the screw head to determine the graft failure load during screw tightening. Next, a tensile load (200 N) was applied to the graft to determine the failure load due to biceps muscle traction. RESULTS In the screw compression, the failure loads in the 5-, 10-, 15-, and 20-mm models were 252, 370, 377, and 331 N, respectively. In the tensile load applied to the coracoid graft, the failure load exceeded 200 N for both the 5- and 10-mm models. CONCLUSION The 5-mm graft had a high risk of fracture during intraoperative screw tightening. As for the biceps muscle traction, the 5- and 10-mm-grafts had a lower failure risk than the 15- and 20-mm-grafts. Therefore, we believe that the optimal length of the coracoid graft is 10 mm in the modified Bristow procedure.

Abstract
Background In the Latarjet procedure, the ideal placement of the coracoid graft in the medial-lateral position is flush with the anterior glenoid rim. However, the ideal position of the graft in the superior-inferior position (sagittal plane) for restoring glenohumeral joint stability is still controversial. Purpose To compare coracoid graft clockface positions between the traditional 3 to 5 o'clock and a more inferior (for the right shoulder) 4 to 6 o'clock with regard to glenohumeral joint stability in the Latarjet procedure. Study Design Controlled laboratory study. Methods A total of 10 fresh-frozen cadaveric shoulders were tested in a dynamic, custom-built robotic shoulder model. Each shoulder was loaded with a 50-N compressive load while an 80-N force was applied in the anteroinferior axes at 90° of abduction and 60° of shoulder external rotation. Four conditions were tested: (1) intact, (2) 6-mm glenoid bone loss (GBL), (3) Latarjet procedure fixed at 3- to 5-o'clock position, and (4) Latarjet procedure fixed at 4- to 6-o'clock position. The stability ratio (SR) and degree of lateral humeral displacement (LHD) were recorded. A 1-factor random-intercepts linear mixed-effects model and Tukey method were used for statistical analysis. Results Compared with the intact state (1.77 ± 0.11), the SR was significantly lower after creating a 6-mm GBL (1.14 ± 0.61, P = .009), with no significant difference in SR after Latarjet 3 to 5 o'clock (1.51 ± 0.70, P = .51) or 4 to 6 o'clock (1.55 ± 0.68, P = .52). Compared with the intact state (6.48 ± 2.24 mm), LHD decreased significantly after GBL (3.16 ± 1.56 mm, P < .001) and Latarjet 4 to 6 o'clock (5.48 ± 3.39 mm, P < .001). Displacement decreased significantly after Latarjet 3 to 5 o'clock (4.78 ± 2.50 mm, P = .04) compared with the intact state but not after Latarjet 4 to 6 o'clock (P = .71). Conclusion The Latarjet procedure in both coracoid graft positions (3-5 and 4-6 o'clock) restored the SR to the values measured in the intact state. A more inferior graft position (fixed at 4-6 o'clock) may improve shoulder biomechanics, but additional work is needed to establish clinical relevance. Clinical Relevance An inferior coracoid graft fixation, the 4- to 6-o'clock position, may benefit in restoring normal shoulder biomechanics after the Latarjet procedure.

Song Q, Gao A, Bai J, Shao Z, Cui G. The Arthroscopic Bristow Procedure Is Superior to the Arthroscopic Latarjet Procedure in Return to Sports but Inferior in Graft Healing: A Comparative Study With 3.4-Year Follow-Up. Arthroscopy 2023; 39:2423-2433. [PMID: 37270110 DOI: 10.1016/j.arthro.2023.05.022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/21/2022] [Revised: 05/13/2023] [Accepted: 05/18/2023] [Indexed: 06/05/2023]
Abstract
PURPOSE To compare clinical and computed tomography outcomes between the arthroscopic Latarjet procedure and the arthroscopic Bristow procedure. METHODS Patients who underwent arthroscopic Latarjet or Bristow procedures with at least 2 years of follow-up were retrospectively reviewed. Thirty-eight shoulders were included in the Latarjet group, and 34 were included in the Bristow group. Recurrence of dislocation, clinical scores, rate of return to sports (RTS), and computed tomography assessment findings (position of transferred coracoid, graft healing, graft absorption, and glenohumeral degenerative osteoarthritis [OA]) were obtained at final follow-up. RESULTS No recurrent dislocation occurred in either group, and no significant differences in clinical scores were found between the 2 procedures, with a mean follow-up period of 3.4 years. The operative time in the Bristow group was significantly shorter than that in the Latarjet group (P < .001). The transferred coracoid had healed in 94.7% of the patients in the Latarjet group and 85.3% in the Bristow group at final follow-up (P = .01). No significant difference in graft absorption or the degree of glenohumeral OA was detected between the 2 groups. However, moderate to severe OA only occurred in the Latarjet group at final follow-up (4 of 38 shoulders, 10.5%). The postoperative external rotation angle and level of RTS favored the Latarjet procedure (P = .030 and P = .034, respectively). CONCLUSIONS Both the arthroscopic Latarjet and arthroscopic Bristow procedures led to good clinical scores with no new dislocation episodes. The Bristow group showed significantly less graft healing than the Latarjet group. However, the arthroscopic Bristow procedure took less operative time and showed a lower rate of early moderate to severe glenohumeral OA, better range of motion, and a higher rate of RTS. LEVEL OF EVIDENCE Level III, retrospective comparative therapeutic trial.

Abstract
PURPOSE To investigate the clinical outcomes and radiologic evaluation of an all-arthroscopic Latarjet procedure with modified button fixation. METHODS Patients who received all-arthroscopic Latarjet procedure with modified suture button fixation between September 2015 to September 2016 were retrospectively reviewed. Indications for surgery were recurrent anterior shoulder dislocation with any 1 of these 3 conditions: glenoid defect >15%, contact-sport athlete, or failure after Bankart repair. Inclusion criteria included cases who received this surgery. Clinical outcomes were evaluated by University of California Los Angeles, ASES and Rowe score with a minimal follow-up of 3 years. Radiologic assessment on 3D computed tomography scan was performed preoperatively and postoperatively at different time points. Complications were also recorded. RESULTS A total of 30 patients were eventually included in this study. The mean follow-up time was 38.0 ± 2.5 months. There were 25 patients who performed contact sports. Of them, 10 patients were without glenoid defect >15% or failed Bankart repair. The remaining 20 patients had glenoid defect >15%, including 2 failed Bankart cases. Ten patients had glenoid defect < 13.5%, and the rest 20 patients had > 13.5%. UCLA, American Shoulder and Elbow Surgeons, and Rowe score significantly improved during follow-up, and the improvement exceeded MCID for all patients. No severe complications were noted. In total, 86.7% of the graft positioning was measured as flush and 13.3% as medial. The bone union rate was 96.7% at 3 months postoperatively and at final follow-up. The remodeling process for the restoration of the normal anatomy of the lower part of glenoid was noted. CONCLUSIONS All-arthroscopic Latarjet with modified suture button fixation can achieve stable fixation of the coracoid, good clinical outcomes (all patients with improvement exceeding MCID), low complications rate. Furthermore, the bone remodeling process contributes to the recovery of the normal anatomy of anteroinferior glenoid. STUDY DESIGN Case series; Level of evidence, 4.

Abstract
The shoulder joint is vulnerable for injuries following trauma and in the context of sporting activities. Degenerative rotator cuff disease is also a common entity. Conservative therapy is often not indicated or does not lead to the desired success, so surgical intervention is necessary. Routine follow-ups, but also persistent complaints, delayed healing, or recurrent trauma, usually need postoperative imaging of the shoulder. The choice of the adequate imaging modality and technique is important to reach the correct diagnosis. Additionally, knowledge of the most common surgical procedures, as well as typical normal findings and expected pathologies on different imaging modalities, is crucial for the radiologist to play a relevant role in the postoperative diagnostic process. This article addresses postoperative imaging after rotator cuff repair, shoulder arthroplasty, and surgery for shoulder stabilization with an emphasis on computed tomography and magnetic resonance imaging.

Abstract
Background: Coracoid transfer is a reliable method for managing anterior shoulder instability in athletes who play contact sports; however, differences between the Bristow and Latarjet procedures are unclear. Purpose: To compare clinical outcomes and rates of bone union and bone resorption of the coracoid process between the open Bristow and open Latarjet procedures in rugby players. Study Design: Cohort study; Level of evidence, 3. Methods: Rugby players who underwent an open Bristow or an open Latarjet procedure were retrospectively reviewed for anterior shoulder instability, and 66 shoulders in the Bristow group and 35 in the Latarjet group were included. Graft union and resorption were evaluated using computed tomography at 3 months to 1 year postoperatively. Patient-reported outcome measures (American Shoulder and Elbow Surgeons score, Rowe score, and satisfaction rate) were obtained at a mean follow-up of 74 months (range, 45-160 months) for Bristow and 64 months (range, 50-76 months) for Latarjet procedures. Recurrence and the rate of return to play (RTP), frequency of pain after RTP, and retirement rate after RTP were also assessed. Results: In 97.1% of the Latarjet procedure cases, bone union of the coracoid was achieved at 3 months postoperatively; however, bone union was achieved in only 72.7% of the Bristow procedure cases at 6 months postoperatively. Bone resorption of the coracoid process occurred in 6.1% of shoulders after the Bristow procedure, whereas 100% of shoulders showed bone resorption after the Latarjet procedure. No statistical differences were found in outcome scores between the 2 procedures. Subluxation and persistent pain after returning to sports were identified at a significantly higher rate in the Latarjet group (5 shoulders [14%] and 9 shoulders [26%], respectively) than in the Bristow group (2 shoulders [3%] and 2 shoulders [3%]) (P = .0471 and P = .001, respectively). Conclusion: The Latarjet procedure had an advantage in the early and high rate of bone union but was at a disadvantage in bone resorption compared with the Bristow procedure. Subluxation and pain after returning to sports were more frequent in patients who underwent the open Latarjet procedure than in those who underwent the open Bristow procedure.

Editorial Commentary: Posterior Shoulder Instability Surgical Treatment Outcomes Are Inferior to Outcomes of Anterior Instability: Standardization of Patient Evaluation and Indications Could Improve Results. Arthroscopy 2022; 38:564-566.

Abstract
Arthroscopic capsulolabral repair remains the mainstay of treatment in patients with refractory shoulder posterior instability. In addition, glenoid bone block augmentation procedures for posterior shoulder instability are gaining momentum. Unfortunately, results from anterior glenoid bone block augmentation procedures have enjoyed much better success than posterior, and it is unclear why surgical treatment of posterior instability with either congenital or acquired retroversion, with or without posterior bone loss, can result in complications or poor outcomes. It is essential to standardize evaluation and reporting of clinical presentation, radiographic assessment, indications, and mid- to long-term follow-up in patients who undergo posterior shoulder bony augmentation procedures. Current literature suggests that greater than 11% posterior glenoid bone loss increases risk of surgical failure 10 times, and 15% posterior bone loss increases risk of surgical failure 25 times, suggesting a possible threshold for posterior bony augmentation. However, in the end, the problem is complex, and work remains to better define optimal patient indications in consideration of congenital or acquired pathology, retroversion, amount of bone loss, and patient demographics and risk factors.

Abstract
OBJECTIVE To introduce an arthroscopic "inlay" Bristow procedure based on the Mortise-Tenon joint structure concept using suture button fixation, and to evaluate its clinical and radiology results postoperatively with a minimal 3-year follow-up. METHODS A total of 56 patients who received arthroscopic "inlay" Bristow procedure with suture button fixation between June 2015 to June 2016 were eventually enrolled in this study. Radiological assessment on the 3D CT scan was performed preoperatively, immediately after operation, and postoperatively at the end of 3 months, 6 months and the final follow-up. Complications postoperatively were also recorded. RESULTS A total of 56 patients were finally included in this study. The mean follow-up time was (36.1±3.7) months. Coracoid grafts (middle point) were positioned at about 4 o'clock (123.8°±12.3°) in the En-face view. In the axial view, 95% (53/56) of the grafts positioning were measured as flush, 5% (3/56) as medial. Bone union rate was 96.4% at the final follow-up. At the end of 3 months, 6 months, and the final follow-up, the length of the coracoid graft was 96.9%±4.9%, 91.9%±6.2%, and 91.6%±6.6% of the immediate postoperative length, respectively. Compared with the immediate postoperative length, the length measured at the end of 3 months shortened not significantly (t=2.12, P > 0.05). The coracoid graft shortened more pronouncedly 6 months postoperatively (t=4.98, P < 0.05) and then remained almost constant over time (t=-0.75, P > 0.05), with all grafted coracoid graft retaining more than 90% of their initial length by the 3-year follow-up. And new bone formation at the junction between the coracoid graft and glenoid neck in the axial view were obviously noted in 25 cases. The quantitative evaluation showed that the glenoid area in En-face view was significantly increased at the final follow-up than that immediately after surgery [(9.72±1.22) cm2 vs. (9.42±1.11) cm2]. No degenerative changes were noted on CT images in all the patients at the final follow-up. CONCLUSION This study reported a series of "inlay" Bristow procedure with suture button fixation for recurrent shoulder dislocation, providing satisfactory union rate and excellent graft positioning. And using suture button fixation instead of screw can reduce osteolysis and complications related to hardware implantation. Moreover, the bone remodeling between the coracoid process and glenoid could be beneficial to restoring the anterior stability of shoulder joint in a long term follow-up.

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. [PMID: 33711500 DOI: 10.1016/j.jse.2021.02.014] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/22/2020] [Revised: 02/10/2021] [Accepted: 02/13/2021] [Indexed: 02/01/2023]
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.

Abstract
Bony lesions are highly prevalent in anterior shoulder instability and can be a significant cause of failure of stabilisation procedures if they are not adequately addressed. The glenoid track concept describes the dynamic interaction between the humeral head and glenoid defects in anterior shoulder instability. It has been beneficial for understanding the role played by bone defects in this entity. As a consequence, the popularity of glenoid augmentation procedures aimed to treat anterior glenoid bone defects; reconstructing the anatomy of the glenohumeral joint has risen sharply in the last decade. Although bone defects are less common in posterior instability, posterior bone block procedures can be indicated to treat not only posterior bony lesions, attritional posterior glenoid erosion or dysplasia but also normal or retroverted glenoids to provide an extended glenoid surface to increase the glenohumeral stability. The purpose of this review was to analyse the rationale, current indications and results of surgical techniques aimed to augment the glenoid surface in patients diagnosed of either anterior or posterior instability by assessing a thorough review of modern literature. Classical techniques such as Latarjet or free bone block procedures have proven to be effective in augmenting the glenoid surface and consequently achieving adequate shoulder stability with good clinical outcomes and early return to athletic activity. Innovations in surgical techniques have permitted to perform these procedures arthroscopically. Arthroscopy provides the theoretical advantages of lower morbidity and faster recovery, as well as the identification and treatment of concomitant pathologies.

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.

J Shoulder Elbow Surg 2020; 29:2632-2639.

Abstract
BACKGROUND Although the osteolysis of the coracoid graft is frequently observed after the Latarjet procedure particularly in its proximal part, its pathomechanism is not well understood. METHODS Three-dimensional finite element glenohumeral joint models were developed using CT-DICOM data of 10 normal shoulders. A 25% bony defect was created on the anterior glenoid rim, and the coracoid process was transferred flush with the glenoid cartilage using 2 half-threaded screws. In the hanging arm as well as in the 90° abducted positions, a compressive load (50 N) 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. Next, elastic analysis was performed, and the distribution patterns of the equivalent stress as well as the maximum principal stress were compared among 4 parts (proximal/distal and medial/lateral) of the coracoid graft. RESULTS Both the equivalent stress and the maximum principal stress were reduced in the proximal half of the coracoid graft. A high stress concentration was observed in the lateral aspect of the coracoid graft particularly in the 90° abducted position. The proximal-medial part demonstrated the lowest equivalent stress as well as the maximum principal stress for both arm positions, which were significantly lower than those in the distal 2 parts. CONCLUSION In the Latarjet procedure, the proximal-medial part of the coracoid graft demonstrated the most evident stress shielding, which may play an important role in postoperative osteolysis.

Abstract
Objective To evaluate the early clinical and radiographic results of arthroscopic Latarjet procedure using screw or suture‐button fixation in patients with recurrent anterior shoulder dislocation. Methods Twelve patients who underwent arthroscopic Latarjet procedure between January 2015 and December 2018 at our institution were retrospectively studied. Data of the patients' history, including age, gender, side of affected arm, body mass index (BMI), and the number of dislocations since fist dislocation were collected. Preoperative and postoperative clinical follow‐up data were evaluated using Walch–Duplay score, American Shoulder and Elbow Society (ASES) score, and modified Rowe score. Active external rotation and active internal rotation at 90° of abduction as well as active elevation were evaluated preoperatively and postoperatively. The position and healing condition of the transferred coracoid bony graft were also assessed using computed tomography (CT) and Mimics 19.0 software. Results Mean follow‐up was 24.9 months (range, 13 to 53 months) of all patients. At final follow‐up, the average ASES score (preoperative vs postoperative values) had improved from 68.9 ± 7.9 to 91.1 ± 6.1 in screw fixation group and 68.9 ± 8.9 to 87.5 ± 6.7 in suture‐button fixation group; the average Rowe score (preoperative vs postoperative values) had improved from 25.0 ± 8.4 to 92.5 ± 4.2 in screw fixation group and 21.7 ± 13.7 to 93.3 ± 4.1 in suture‐button fixation group; the average of Walch–Duplay score (preoperative vs postoperative values) had improved from 12.5 ± 15.1 to 91.7 ± 4.1 in screw fixation group and 18.3 ± 20.7 to 88.3 ± 7.5 in button fixation group. The forward flexion was 175.0° ± 8.4° preoperatively and 178.3° ± 4.1° postoperatively in screw fixation group while 174.8° ± 10.2° preoperatively and 175.0° ± 5.5° postoperatively in suture‐button fixation group. The active external rotation was 77.5° ± 5.2° preoperatively and 71.7° ± 4.1° postoperatively in screw fixation group while 72.5° ± 6.9° preoperatively and 68.3° ± 7.5° postoperatively in suture‐button fixation group. The average of active internal rotation was 66.7° ± 6.1° preoperatively and 67.5° ± 6.1° postoperatively in screw fixation group while 68.3° ± 11.3° preoperatively and 66.7° ± 7.5° postoperatively in suture‐button fixation group. In postoperative CT scan, 91.7% grafts midline center were located at or under the equator in the en face view; 75% of the bone blocks were flush to the glenoid face in the axial view, with only two grafts exhibiting slight medial placement in screw fixation group (33.3%) and one graft exhibiting slight lateral placement in suture‐button fixation group (16.7%). All grafts achieved bone union. Graft absorption mostly occurred outside of the “best‐fit” circle. The average bony absorption rates of the coracoid grafts were 25.2% and 10.18% in screw fixation group and suture‐button fixation group, respectively, at 6 months postoperative follow‐up. Conclusion Both suture‐button fixation and screw fixation techniques in arthroscopic Latarjet procedure revealed excellent clinical outcomes with low complication rates in the early follow‐up. The suture‐button fixation exhibited a flexible fixation pattern that allowed for self‐correction to some extent, even slight lateralization could finally remodel over time.

Abstract
Background: The Latarjet procedure is a popular means to surgically address anterior glenohumeral joint instability. Although the Latarjet procedure is becoming increasingly common, challenges persist and include postoperative complications secondary to use of the conventional 2 bicortical fixation screws. Recently, a novel surgical technique using a guided surgical approach for graft positioning with nonrigid fixation via a suture suspensory system has been described. Purpose: To evaluate healing rates and stability of the grafts in patients who underwent this new Latarjet technique. Study Design: Case series; Level of evidence, 4. Methods: We retrospectively gathered anonymized computed tomography (CT) data sets from a total of 107 patients who underwent nonrigid suture fixation using a cortical button fixation for anterior glenohumeral instability. Of the 107 patients, 45 had CT scans performed at 2 different time periods. The CT scans of each patient were compared by 2 fellowship-trained musculoskeletal radiologists. Data recorded included age, sex, date of scan, initial graft position on the glenoid, presence and degree of graft migration relative to the equator on follow-up scan, and percentage of osseous healing (as assessed by osseous bridging) on the follow-up scan. Descriptive statistics were calculated to evaluate the average migration and average percentage of healing at both time points. Results: Our population (n = 45) consisted of 38 men (84.4%) and 7 women (15.6%). The mean age was 27.1 ± 1.1 years. The mean time between initial CT scan (2 weeks postoperatively) and follow-up CT scan was 26 ± 2 weeks. On follow-up scan, reviewer 1 found 75.6% of patients had greater than 75% healing, and reviewer 2 found 70.2% of patients had greater than 75% healing. The center of the graft was measured at or below the equator on follow-up examination in 43 of 45 (95.6%) patients by reviewer 1 and 44 of 45 (97.8%) patients by reviewer 2. Conclusion: Based on these findings, nonrigid suture fixation using a cortical button device offers an effective alternative to traditional screw fixation for the Latarjet procedure with a high level of osseous healing and minimal graft migration.

Abstract
BACKGROUND Coracoid graft positioning, fixation, and bone union are key factors affecting the clinical outcomes of Bristow and Latarjet procedures. We developed an arthroscopic "inlay" Bristow procedure based on the "mortise-tenon" joint structure concept using suture button fixation to achieve more stable fixation and better bone union of the graft. PURPOSE To evaluate the positioning of the coracoid graft, bone union rate, and clinical outcomes of this arthroscopic inlay Bristow procedure with suture button fixation. STUDY DESIGN Case series; Level of evidence, 4. METHODS A total of 62 patients who received the arthroscopic inlay Bristow procedure with suture button fixation between June 2015 to June 2016 were eligible for inclusion, and 56 patients who met the inclusion criteria were enrolled in this study. Radiological assessment on 3-dimensional computed tomography scan was performed preoperatively, immediately after the operation, and postoperatively at 3 months, 6 months, 1 year, and the final follow-up. Pre- and postoperative clinical results were also assessed. RESULTS A total of 56 patients were included in this study. The mean ± SD follow-up time was 36.1 ± 3.7 months. Coracoid grafts (middle point) were positioned at 4 o'clock (range, 123.8°± 12.3°) in the sagittal view. In the axial view, 94.6% (53/56) of the graft positioning was measured as flush and 5.4% (3/56) as medial. Neither lateral nor too medial positioning was noted. The bone union rate was 96.4% at final follow-up. The mean visual analog scale score for pain during motion, American Shoulder and Elbow Surgeons score, and Rowe score all improved significantly after surgery-from 4.8 ± 2.6 to 1.1 ± 1.0, 69.2 ± 12.5 to 92.5 ± 7.0, and 33.5 ± 12.1 to 96.0 ± 4.9 at last follow-up, respectively. Almost all patients (98%; 55/56) returned to sports within 1 year after surgery at the same or higher level as compared with their preinjury performance. The mean subjective value for sports participation was 90.3% ± 7.1% (range, 70%-100%) as compared with the normal shoulder. The overall complication rate was 3.6%. No degenerative changes were noted in any patients. CONCLUSION This study reported the first series of an inlay Bristow procedure with suture button fixation for recurrent shoulder dislocation, providing a satisfactory union rate and excellent graft positioning with a low complication rate. The mortise-tenon joint structure can provide excellent graft fixation and healing, while using suture button fixation instead of screw fixation could reduce osteolysis and complications related to hardware implantation.

Abstract
Aim Positioning and fixation of the bone block during revision anterior stabilization of the shoulder, in the presence of significant retained glenoid metalwork, can be challenging. We present the results of a series of patients who underwent a revision bone block procedure secured with double suture buttons using a drill guide system, the position of which was calculated from a preoperative computed tomography (CT) scan. Materials and methods We undertook a revision bone block stabilization of the shoulder, using a guided double suture-button fixation, in 10 patients with significant retained glenoid metalwork from previous procedures. A preoperative CT scan was used to determine a position for the guide to allow a safe drill trajectory that would avoid any retained metalwork. A coracoid transfer was undertaken in 4 patients and an Eden-Hybinette in 6. Patients were assessed preoperatively and at final follow-up clinically and using the Oxford Shoulder Instability Score and the Subjective Shoulder Value score. Bone block position and healing was assessed by a CT scan at 6 months. The median follow-up was 36 months (range, 24-47 months). Results There were 3 female and 7 male patients with a median age of 24.5 years (17-49 years). At final follow-up, the mean Oxford Shoulder Instability Score had decreased from 25.9 (range, 21-35) to 5.8 (range, 3-14) (P < .005). The mean Subjective Shoulder Value score had risen from 87.1 (range, 10-60) to 80 (range, 60-90) (P < .05). All of the patients considered their shoulder to be stable apart from 1 patient. There had been no redislocations. The bone block positioned in the glenoid lower quadrant had healed for all of the patients on CT at 6 months. Conclusion Guided suture-button fixation of the bone block during revision anterior stabilization of the shoulder, in the presence of significant retained glenoid metalwork, provides a satisfactory outcome in terms of shoulder stability, graft position, and healing.

Abstract
BACKGROUND Since the description of the arthroscopic Latarjet technique, discussion about the superiority of the open or arthroscopic procedure has arisen. The appropriate placement of the coracoid graft (CG) on the anterior glenoid neck is reported to be the most important step of the Latarjet procedure. PURPOSE To verify if there are differences in the parameters that may affect the final position and fixation of CG obtained from the open and arthroscopic Latarjet techniques. STUDY DESIGN Controlled laboratory study. METHODS Twenty fresh-frozen human paired cadaveric shoulder specimens were randomly distributed in 2 surgery groups (open group [OG] and arthroscopic group [AG]) with 10 specimens in each. Two surgeons, each with experience performing open and arthroscopic Latarjet techniques, executed these procedures: one surgeon performed all open techniques, and the other performed all arthroscopic techniques, respectively. After surgery, a computerized tomography scan was performed. The surgical time, the position of each CG, a series of variables that might affect the CG fixation, and the level of the subscapularis muscle split were evaluated. RESULTS The mean surgical time was significantly longer in the AG (mean, 26 minutes for OG and 57 minutes for AG). Three intraoperative complications (30%) were identified in the AG, consisting of graft fractures. The CG was determined to be in an optimal cranial-caudal position in 90% of specimens of the OG and 44% of the AG (Fisher, P = .057). In both groups, the CG was placed in an optimal medial-lateral position in all specimens. In the OG, the degree of parallelism between the major axes of the glenoid surface and CG was significantly greater than in the AG (mean, 3.8º for OG and 15.1º for AG). No significant differences were observed in superior and inferior screw orientation between the groups. In the longitudinal and transverse directions, significant differences were found in the centering of the superior screw, being closer to the ideal point in the OG than in the AG. The location where the longitudinal subscapularis muscle split was performed was significantly higher in the AG. CONCLUSION The open Latarjet technique required less surgical time; presented a lower number of intraoperative complications; and allowed more adequate placement of the CG, better centering of the screws, and a subscapularis muscle split closer to the ideal position. CLINICAL RELEVANCE The reported benefits of the arthroscopic Latarjet technique seem less clear if we take into account the added surgery time and complications.

Influence of coracoid anatomy on the location of glenoid rim defects in anterior shoulder instability: 3D CT-scan evaluation of 51 patients. Surg Radiol Anat 2020; 42:895-901.

Abstract
PURPOSE Glenoid bony lesions play a role in approximately half of anterior shoulder instability cases. The purpose of this study is to see if the anatomy of the coracoid affects the location of glenoid rim defects. We hypothesized that a prominent coracoid (lower and lateral) would be more likely to cause an anterior-inferior glenoid lesion, and a less prominent coracoid more prone to cause an anterior lesion. The null hypothesis being the absence of correlation. METHODS Fifty-one shoulder CT-scans from a prospective database, with 3D reconstruction, were analyzed. The position of glenoid lesions was identified using the validated clock method, identifying the beginning and end time. The size of bony glenoid defects was calculated using the validated glenoid ratio method. The position of the coracoid tip was measured in three orthogonal planes. RESULTS Analysis included 25 right shoulders and 26 left shoulders in seven females and 41 males. The vertical position of the coracoid tip relative to the top of the glenoid was highly correlated to the location of the glenoid defect on the profile view (r = -0.625; 95% CI 0.423-0.768; p = 0.001). Thus, higher coracoids were associated with anterior lesions, while lower coracoids were associated with anterior-inferior lesions. A more laterally prominent coracoid was also correlated with anterior-inferior lesions (r = 0.433; 95% CI 0.179-0.633; p = 0.002). CONCLUSION This study shows that coracoid anatomy affects the location of bony Bankart defects in anterior shoulder instability. Lower and laterally prominent coracoids are associated with anterior-inferior lesions. This variation in anatomy should be considered during pre-op planning for surgeries involving bone graft.

Abstract
PURPOSE The purpose of this study was to compare the clinical, functional, and radiographic outcomes of open versus arthroscopic Latarjet procedures. METHODS Between December 2009 to January 2015, all patients older than 18 years of age who were treated with a Latarjet procedure for chronic osseous anterior instability by a single surgeon were included in this retrospective cohort study. Range of motion, strength, Rowe, Western Ontario Shoulder Instability Index (WOSI) scores, and pain level according to the Visual Analog Scale (VAS) were evaluated. In addition, postoperative computed tomography scans were used to evaluate the position of the transferred coracoid, screw orientation, and degree of graft resorption. RESULTS Forty-eight patients with a mean age of 29.5 years (range 19-59 years) who underwent open (n = 15; group OL) and arthroscopic (n = 33; group AL) Latarjet procedures were included in the study. The mean follow-up was 30.5 months (range 24-50 months). At final follow-up there were significant differences in the mean internal rotation loss (mean of 9° vs 14°, P = .044) favoring open surgery and WOSI (P = .017) scores favoring arthroscopic. No significant differences were detected in mean forward flexion loss (P = .918), external rotation loss (P = .883), Rowe (P = .429), and Visual Analog Scale (P = .208) scores. Mean superoinferior position of the coracoid bone graft was found between the 1:55 and 4:49 o'clock positions (2:05-4:55 for group OL; 1:51-4:47 for group AL) in en-face views. The grafts were placed laterally in 13% (group OL) and 9% (group AL) of patients. The mean α angles of the screws were 11° and 19.2°, respectively (P = .004). The mean graft resorption rates were 21% and 34% (P = .087), respectively. CONCLUSION Good functional results were obtained after both open and arthroscopic Latarjet procedures for the treatment of chronic osseous anterior shoulder instability. Comparative analysis showed small but statistically significant differences in internal rotation loss favoring open and in WOSI favoring arthroscopic techniques. All measured radiographic parameters were similar with the exception of a significant difference in alpha angle with improved screw position in open surgery. OL and AL techniques provide similar clinical and radiographic outcomes. LEVEL OF EVIDENCE III; Retrospective cohort study with comparison group.

Abstract
PURPOSE To analyze the functional results after unipolar or bipolar arthroscopic soft tissue stabilization in the treatment of recurrent anterior instability after a coracoid bone block procedure. METHODS We studied a retrospective series of 41 patients (33 male, 8 female) with recurrent anterior shoulder instability after Bristow (n = 7) or Latarjet (n = 34) coracoid bone block treated with unipolar (isolated Bankart, n = 22) or bipolar (Bankart + Hill-Sachs remplissage, n = 19) arthroscopic stabilization. RESULTS The mean follow-up was 72 (25-208) months. Severe glenoid erosion (>25%) was found in 17 patients, and a medium or deep Hill-Sachs lesion (Calandra 2 and 3) was found in 24 patients. A radiographic control was available in 28 patients at final follow-up. Five patients (12%) presented a recurrence of instability (4 subluxations, 1 dislocation). Two patients required revision surgery, 1 in each group. At final follow-up, persistent anterior apprehension was more frequent in patients presenting with severe glenoid bone loss (P = .04) and in patients with medium or deep Hill-Sachs lesions who were treated with unipolar stabilization (P = .04). Return to sports was achieved in 81% of cases. Visual analog scale was 1.3 ± 2, subjective shoulder value was 83% ± 18%, Rowe score was 78 ± 24, and Walch-Duplay score was 76 ± 28. No patients developed severe glenohumeral arthritis (Samilson 4). CONCLUSIONS Arthroscopic soft tissue stabilization provides good functional results after failed coracoid bone block with an acceptable rate of recurrence and a return to sports in most cases. Patients with significant Hill-Sachs lesions showed better results when treated with combined Bankart repair and Hill-Sachs remplissage. Severe glenoid bone loss was associated with poorer functional results. LEVEL OF EVIDENCE Level IV, case series.

Abstract
Background As several neurologic and hardware complications have been reported with screw fixation. Suture buttons are used to serve as an alternative to screw fixation to obtain better outcome and to reduce the complication. The purpose of this study was to observe the clinical outcomes and make the radiologic assessment of a modified suture button (MSB) arthroscopic Latarjet procedure. Methods A total of ninty-one patients with recurrent shoulder joint dislocation who underwent MSB arthroscopic Latarjet procedure was retrospectively reviewed. Fifty cases identified from the chart review met the inclusion criteria. The clinical outcomes and position of the grafts, glenohumeral degeneration, and graft healing condition were assessed postoperatively in a follow-up with at least one and half of a year. Results All the fifty patients were satisfied with their clinical outcome. The overall complication rate was 4% in this study. The mean visual analog scale score, the affected shoulder active mobility in Ers(external rotation at the side), Era(external rotation in abduction) decreased significantly; the ASES score, Rowe score, Walch-Duplay score improved significantly. CT scans in the sagittal view showed that grafts in 88% of cases were in good position, grafts in 12% of cases were fixed too superiorly and inferiorly. In the axial view grafts in forty cases were flush with the glenoid rim, ten were considered as too lateral. The ten grafts became remodeled and were more flush with the glenoid rim in the follow-up. Conclusions The MSB arthroscopic Latarjet procedure provides excellent outcome with few complications, and no degenerative changes were observed in the follow-up. Moreover, the graft fixed too laterally presented a phenomenon of remodeling and became flush with the glenoid rim over time.

Abstract
PURPOSE To investigate whether arthroscopic Latarjet procedure significantly differs from the open procedure as for the clinical, functional and radiographic outcomes. METHODS Two reviewers independently conducted a systematic search according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses using the MEDLINE/PubMed database and the Cochrane Database of Systematic Reviews. These databases were queried with the terms "shoulder" AND "anterior" AND "instability" AND "Latarjet". RESULTS From the 259 initial papers, we finally assessed five clinical studies which were eligible to our inclusion-exclusion criteria. The mean modified Coleman score for methodological deficiencies of the studies was 65.4/100, whereas it ranged from 53/100 to 77/100. The arthroscopic technique illustrated comparable results to the open technique regarding the postoperative recurrence rate. No significant difference was found amongst groups in relation to the postoperative osteoarthritis, infection rates, soft tissue healing, postoperative mean American Shoulder and Elbow Surgeons score, mean Walch-Duplay score, fatty infiltration of the subscapularis muscle and posterior protrusion of the screw. The arthroscopic technique yielded significantly superior results as for the non-union rate of the graft, the total graft osteolysis and graft resorption, the mean Western Ontario Shoulder Instability Index score and the early postoperative pain. CONCLUSIONS Both the open and the arthroscopic Latarjet procedures led to satisfactory radiographic and clinical outcomes for the treatment of patients with recurrent anterior shoulder instability and significant glenoid bone loss. However, the overall quality of the studies ranged from low to moderate. LEVEL OF EVIDENCE Comprehensive and systematic review of level II-III therapeutic studies.

Abstract
PURPOSE Despite good clinical results and low recurrence rates, post-operative complications of coracoid process transfer procedures are not well understood. This study aims to evaluate the underlying failure mechanism in cases requiring major open revision surgery after prior Bristow or Latarjet stabilization. METHODS Between January 2006 and January 2017, 26 patients underwent major open revision after primary Bristow or Latarjet procedure. Clinical notes and radiographic images were retrospectively reviewed for all cases to determine underlying pathology. Choice of treatment and clinical and radiographic outcome were similarly reported for all cases. RESULTS The underlying failure mechanism was associated with non-union in 42.3%, resorption in 23.1%, graft malpositioning in 15.4%, and trauma or graft fracture in 19.2% of cases. Although none of the patients reported any dislocations, mean subjective shoulder score was 60.2% and WOSI scores averaged 709.3 points at final follow-up. Radiographic signs of deteriorating degenerative arthritis were seen in 34.6%. CONCLUSION Graft non-union resulting in recurrent instability was the main indication for open revision surgery after Bristow or Latarjet procedure, followed by resorption, malpositioning, and graft fracture in this retrospective case series. Revision surgery consisted of a structural iliac crest bone graft in the majority of cases. Clinical and radiographic outcomes are predictably variable in this population of multioperated patients.

Arthroscopic Versus Open Iliac Crest Bone Grafting in Recurrent Anterior Shoulder Instability With Glenoid Bone Loss: A Computed Tomography-Based Quantitative Assessment. Arthroscopy 2018; 34:352-359. [PMID: 29100764 DOI: 10.1016/j.arthro.2017.07.034] [Citation(s) in RCA: 29] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/16/2017] [Revised: 07/11/2017] [Accepted: 07/28/2017] [Indexed: 02/02/2023]
Abstract
PURPOSE To assess the iliac crest bone graft (ICBG) position in the en-face view and axial plane comparing arthroscopic with open procedures. METHODS A total of 40 consecutive patients with recurrent anterior shoulder instability and glenoid bone loss over 10% treated by 2 independent orthopaedic departments were included. Two independent observers analyzed preoperative and immediate postoperative computed tomography scans of 20 open (group O) and 20 arthroscopic (group A) procedures. Defect and ICBG characteristics of the J-shaped graft in the en-face view and axial plane were manually assessed by multiplanar reconstructed computed tomography scans. Variances in terms of graft positioning were analyzed. RESULTS No significant variances in arthroscopic graft positioning were observed. The graft position in the en-face view was comparable in both groups, with the superior extent of the arthroscopic graft (40° ± 9° [inferior extent, 139° ± 16°]) lying significantly higher than the superior extent in group O (50° ± 13°, P = .005 [inferior extent, 147° ± 21°; P = .178]). The covered glenoid defect size was above 95% (98% ± 1% in group O vs 95% ± 2% in group A, P = .001). The arthroscopic graft in the axial plane showed a significantly steeper impaction angle (34.8° ± 7.8° vs 26.9° ± 9.9°, P = .010), with a significantly increased medial offset compared with group O (6.6 ± 1.7 mm vs 5.4 ± 1.3 mm, P = .024). The mediolateral step formation, however, was not significantly different (2.9 ± 1.1 mm in group A vs 3.2 ± 0.8 mm in group O, P = .289). The interobserver reliability was very good for all measurements (R = 0.969; 95% confidence interval, 0.965-0.972). CONCLUSIONS Positioning of the arthroscopic ICBG in the en-face view and axial plane is comparable to that of the open technique. Good glenoid defect coverage and glenoid concavity reconstruction can be achieved with the arthroscopic technique. The main difference compared with the open procedure is the significantly steeper impaction angle. LEVEL OF EVIDENCE Level III, case-control study.

Abstract
This classic discusses the original publication ‘Treatment of recurrent dislocation of the shoulder’ on the Latarjet procedure. This surgical technique that has become one of the basics in shoulder-stabilising surgery, introduced by Latarjet in 1954 in the journal Lyon Chirurgical. Inspired by publications of colleagues in the field of shoulder surgery, Latarjet introduced a technique that transfers the coracoid process to the anterior glenoid rim in patients with anterior shoulder instability. Although being outrun in popularity by the Bankart repair for several decades, improved knowledge regarding long-term outcomes, surgical techniques and patient characteristics such as bone loss and participation in contact sports has led to renewed interest in the Latarjet procedure. This especially accounts for patients with significant glenohumeral bone loss or patients with a previously failed soft tissue repairs. Whereas the increase in popularity has led to many studies focussing on various aspects, the 15 basics of the initial procedure have virtually remained unchanged.

Reliability of a CT reconstruction for preoperative surgical planning in the arthroscopic Latarjet procedure. Knee Surg Sports Traumatol Arthrosc 2018; 26:40-47. [PMID: 27734111 DOI: 10.1007/s00167-016-4329-1] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/09/2016] [Accepted: 09/15/2016] [Indexed: 10/20/2022]
Abstract
PURPOSE The arthroscopic Latarjet procedure has provided reliable results in the treatment of anterior shoulder instability. However, this procedure remains technically challenging and is related to several complications. The morphology of the coracoid and the glenoid are inconsistent. Inadequate coracoid and glenoid preparing may lead to mismatching between their surfaces. Inadequate screws lengthening and orientation are a major concern. Too long screws can lead to suprascapular nerve injuries or hardware irritation, whereas too short screws can lead to nonunions, fibrous unions or migration of the bone block. The purpose of the study was to investigate the application of virtual surgical planning and digital technology in preoperative assessment and planning of the Latarjet procedure. METHODS Twelve patients planned for an arthroscopic Latarjet had a CT scan evaluation with multi-two-dimensional reconstruction performed before surgery. Interobserver and intraobserver reliability were evaluated. The shape of the anterior rim of the glenoid and the undersurface of the coracoid were classified. Coracoid height was measured, respectively, at 5 mm (C1) and 10 mm (C2) from the tip of the coracoid process, corresponding to the drilling zone. Measurements of the glenoid width were then taken in the axial view at 25 % (G1) and 50 % (G2) of the glenoid height with various α angles (5°, 10°, 15°, 20°, 25°, 30°) 7 mm from the anterior glenoid rim. Shapes of the undersurface of the coracoid and the anterior rim of the glenoid were noted during the surgical procedure. Post-operative measurements included the α angle. RESULTS Concerning coracoid height measurements, there was an almost perfect to substantial intra- and inter-reliability, with values ranging from ICC = 0.75-0.97. For the shape of the coracoid, concordances were, respectively, perfect (ICC = 1) and almost perfect (0.87 [0.33; 1]) for the intra- and interobserver reliabilities. Concerning the glenoid, concordance was always almost perfect for 50 % height. Concordance was almost perfect for 25 % height 15° and 30° for inter- and intraobserver, for intraobserver at 0° and 25°. All the other values were still showing moderate concordance. Shape of the coracoid analysis reproducibility was perfect for both intra- and interobserver ICC = 1. There was a total agreement (ICC = 1) between the preoperative evaluation of the shape of the glenoid and the coracoid and the intraoperative assessment. CONCLUSION The ideal and accurate preoperative planning of screwing of the coracoid graft in the arthroscopic Latarjet can be achieved in the real surgery assisted by the virtual planning. The clinical importance of this study lies in the observation that this new preoperative planning could offer a simple, effective and reproducible tool for surgeons helping them to prepare in the best possible way a technically challenging procedure usually associated with a high rate of complications.

Abstract
Background The present study investigated individualized coracoid osteotomy for 3D congruent arc glenoid reconstruction and evaluated the clinical outcomes in recurrent anterior shoulder dislocation. Methods From January 2005 to July 2015, 78 patients with glenoid defect underwent coracoid and conjoint tendon transposition. The patients were divided into the individualized group (n = 34) and the non-individualized group (n = 44). All patients had CT data to reconstruct the shoulder model using Mimics software. In the individualized group, the individual coracoid osteotomy and bone fixation position parameters were measured from preoperative planification through simulating a 3D congruent arc glenoid reconstruction model. The non-individualized group underwent classic Bristow-Latarjet (B-L) procedure. The postoperative evaluation parameters included 3D congruent arc index, coracoid bone position, shoulder osteoarthritis index (Samilson-Prieto) and shoulder function score (Rowe, Constant-Murley score). Results The mean follow-up time was 51.0 months (ranging from 24 to 146). The individualized group got 3D congruent arc reconstruction of the glenoid by postoperative CT scanning. Bone position was more precise in the individual group than that in the B-L group. There was a lower incidence of shoulder osteoarthritis (Samilson-Prieto) in the individual group compared with that in the B-L group: 0 vs 13.6% (mild 6/44, P = 0.027), respectively. No significant difference was observed between the individual and B-L groups in rate of re-dislocation: 0 vs 4.5% (2/44, P = 0.315), respectively. The postoperative Rowe and Constant score was significantly improved but was not significantly different between the two groups. Conclusion The individual procedure achieved 3D congruent arc glenoid reconstruction. The clinical effects in patients with medium glenoid defect were good, especially the low incidence of shoulder osteoarthritis in middle-term follow-up.

Abstract
PURPOSE To investigate the clinical and radiographic outcomes of the modified arthroscopic Latarjet procedure at a minimum of 2 years after surgery. METHODS Patients who had traumatic unidirectional anterior shoulder instability and treated with a modified arthroscopic Latarjet procedure were included. During surgery, the anterior capsule was preserved and repaired back to the glenoid after the coracoid transfer. The clinical results (range of motion, American Shoulder and Elbow Surgeons [ASES] score, Constant-Murley score, and Rowe score) and computed tomographic results were followed. RESULTS From February 2013 to September 2014, 52 consecutive patients were included. The average duration of follow-up was 28.4 months (range, 24.0-41.7 months). At final follow-up, no recurrent dislocation had occurred. The ASES score and Rowe score improved significantly (ASES score from 85.6 ± 12.7 before surgery to 93.6 ± 5.4 after surgery, P < .0001; Rowe score from 41.5 ± 7.2 before surgery to 92.2 ± 8.7 after surgery, P < .0001). No significant change was found regarding range of motion and the Constant-Murley score. Bone union was achieved in all cases. The transferred coracoid was at the level of the glenoid in all cases. The transferred coracoid was placed below the equator in 48 of 52 cases (92.3%). The orientation of the screw was 22.6° ± 10.8°. Bone resorption around the proximal screw was significantly more prominent than that around the distal screw (P < .0001). CONCLUSIONS The arthroscopic Latarjet procedure with concomitant anterior capsular reconstruction can achieve satisfactory clinical outcomes for the treatment of anterior shoulder instability with marked glenoid bone loss at a minimum of 2 years' follow-up. A satisfactory coracoid graft position, proper screw orientation, and high healing rate of the transferred coracoid can be expected. Bone resorption around the proximal screw is more severe than that around the distal screw. LEVEL OF EVIDENCE Level IV, therapeutic case series.

Abstract
UNLABELLED Shoulder dislocation and its treatment are probably as old as time. Surgical treatment has gained acceptance recently, especially in recurrent cases. Within roughly the last 100years, numerous treatment strategies have been developed and questions elucidated regarding the entity of shoulder instability. Shoulder instability holds many eponymous terms. By means of literature and historical research, we present the biographical background of some common eponymous terms and the original publication on which those terms are based. We describe the Perthes lesion, Bankart lesion and repair, Hill-Sachs lesion, Bristow-Latarjet procedure and Eden-Hybbinette procedure. Shoulder instability has been recognized and treated for many centuries. Before the invention of X-rays and the ability to intervene surgically, empirical reduction and time were the only feasible treatment options. Understanding of the pathophysiology of this problem and its corresponding treatment has kept increasing since the 19th century. The originators involved still have their name attached to the different signs and procedures. LEVEL OF EVIDENCE IV.

Abstract
Background One of the factors that can affect the success of the Latarjet procedure is accurate coracoid graft (CG) placement. Hypothesis The use of a guide can improve placement of the CG and screw positioning in the sagittal and axial planes as compared with the classic open ("freehand") technique. Study Design Cohort study; Level of evidence, 2. Methods A total of 49 patients who underwent a Latarjet procedure for the treatment of recurrent anterior shoulder instability were prospectively included; the procedure was performed with the freehand technique in 22 patients (group 1) and with use of a parallel drill guide during screw placement in 27 patients (group 2). All patients underwent a postoperative computed tomography scan with the same established protocol. The scans were used to evaluate and compare the position of the CG in the sagittal and axial planes, the direction of the screws (α angle), and overall contact of the graft with the anterior surface of the glenoid after the 2 surgical techniques. Results The CG was placed >60% below the native glenoid equator in 23 patients (85.2%) in group 2, compared with 14 patients (63.6%) in group 1 (P = .004). In the axial plane, the position of the CG in group 2 patients was more accurate (85.2% and 88.9% flush) at the inferior and middle quartiles of the glenoid surface (P = .012 and .009), respectively. Moreover, with the freehand technique (group 1), the graft was in a more lateral position in the inferior and middle quartiles (P = .012 and .009, respectively). No differences were found between groups 1 and 2 regarding the mean α angle of the superior (9° ± 4.14° vs 11° ± 6.3°, P = .232) and inferior (9.5° ± 6° vs 10° ± 7.5°, P = .629) screws. However, the mean contact angle (angle between the posterior coracoid and the anterior glenoid surface) with the freehand technique (3.8° ± 6.8°) was better than that of the guide (8.55° ± 8°) (P = .05). Conclusion Compared with the classic freehand operative technique, the parallel drill guide can ensure more accurate placement of the CG in the axial and sagittal planes, although with inferior bone contact.

Abstract
INTRODUCTION Coracoid bone graft transfer has become the gold standard in patients with recurrent anterior shoulder instability associated with bony defect. Several studies have shown that the main stabilizing component of this procedure is the sling effect by the conjoint tendon and the lower portion of subscapularis (SS). The purpose of this study was to determine whether a larger SS volume below the bone block was correlated to greater postoperative shoulder stability. MATERIALS AND METHODS This prospective study included a cohort of patients who underwent open coracoid bone graft transfer for post-traumatic recurrent anterior shoulder instability. Forty patients were reviewed at 2 years with a clinical and CT scan evaluation. A correlation analysis assessed the relation between the SS volume index (ratio of SS volume below the bone block to volume over the bone block) and Rowe and Walch-Duplay instability scores. RESULTS There exists a positive and significant correlation between SS volume index and postoperative Rowe score, r=0.37 (P=0.03). The same trend was observed for Walch-Duplay score without statistical significance. A larger inferior SS volume did not result in a limitation of external rotation, greater fatty infiltration, or malposition of the coracoid graft. CONCLUSION A larger SS volume below the bone block is related to greater postoperative shoulder stability. We recommend performing the split in the middle of the SS or higher instead of the junction of the superior two-thirds and inferior one-third as usually reported.

Abstract
Purpose
The aim of this study was to compare the accuracy of the coracoid bone graft placement with the open Latarjet-Patte and arthroscopic Latarjet (arthro-Latarjet) procedures in the treatment of anterior instability of the shoulder.
Methods
Forty-six patients affected by anterior shoulder instability were divided into two groups. In group A (
n
= 25), patients were operated by arthroscopic Latarjet (arthro-Latarjet) procedure and in group B (
n
= 21), patients were operated by open Latarjet-Patte procedure. Instrumental investigation was based on three-dimensional computed tomography (3D-CT) at a minimum 1-year follow-up. Graft placement and integration, divergence and posterior protrusion of the screws, and glenohumeral osteoarthritis were considered as outcomes. Statistical analysis was performed with chi-square or Fisher's exact test. Significance was set at
p
< 0.05.
Results
Positioning of the coracoid graft proved to be optimal in 76% (19/25) of patients of group A and in 100% (21/21) of patients of group B (Fisher's exact test,
p
= 0.025). Screw placement with respect to the glenoid surface showed a posterior divergence in 44% (11/25) of patients in group A and in 24% (5/21) of patients in group B (
p
= 0.15). Posterior protrusion of screw was observed in 76% (19/25) of patients in group A and 71.4% (15/21) of patients in group B (
p
= 0.73). Graft integration was present in 76% (19/25) of patients in group A and 85.7% (18/21) of patients in group B (Fisher's exact test,
p
= 0.48). Mild signs of glenohumeral osteoarthritis were observed in 12% (3/25) of patients in group A and 28.6% (6/21) of patients in group B (Fisher's exact test,
p
= 0.26).
Conclusion
Patients operated with open Latarjet-Patte procedure showed better results than those of the arthro-Latarjet group in reference to the positioning of the graft on the coronal plane (
p
= 0.025). No significant differences between the groups were observed for graft integration, divergence of the screws, posterior protrusion of the screws, and osteoarthritis.
Level of Evidence
Level II, nonrandomized prospective comparative study.

Abstract
BACKGROUND Very few studies have compared open Latarjet versus arthroscopic Latarjet procedures. PURPOSE To compare the clinical and computed tomographic outcomes between open and arthroscopic Latarjet procedures. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS A prospective, comparative study was performed. The open Latarjet group included 44 patients, and the arthroscopic Latarjet group included 46 patients. All patients had more than 2 years of clinical follow-up (range of motion, American Shoulder and Elbow Surgeons [ASES] score, Constant-Murley score, and Rowe score). The position of the transferred coracoid, the screw orientation, and graft resorption were evaluated on computed tomography (CT) scan. RESULTS The surgery time for the open group was significantly shorter than that for the arthroscopic group ( P = .003). No recurrent dislocation occurred in either group. The apprehension test was negative in all patients in both groups. At the final follow-up, no significant difference was detected between the open group and the arthroscopic group regarding any of the clinical outcome measurements. The transferred coracoid graft was level with the glenoid in all patients in both groups. The open group had better position in the superior-inferior direction compared with the arthroscopic group ( P < .001). No significant difference was found in screw orientation between the 2 groups ( P = .102). At 1 year after surgery, patients in the arthroscopic group had significantly less resorption compared with patients in the open group ( P = .044). CONCLUSION Both procedures are effective for the treatment of recurrent anterior shoulder dislocation with marked glenoid bone loss. The open group had better position in the superior-inferior direction compared with the arthroscopic group. At 1 year after surgery, patients in the arthroscopic Latarjet group showed notably less graft resorption compared with patients in the open Latarjet group.

Abstract
Background: Recurrent anterior shoulder instability after coracoid process transfers may be caused by trauma, sports injury, or technical failure of the index procedure. Surgical techniques vary with regard to graft orientation and positioning and number of screws utilized for fixation. Purpose: To identify surgical and patient-related factors associated with failure, defined as the need for revision surgery. We hypothesized that failures will occur more commonly with single-screw fixation and graft malposition. Study Design: Case series; Level of evidence, 4. Methods: Eighty-three patients (mean age, 24 years) who underwent an Eden-Hybinette operation as a revision procedure for recurrent anterior instability after primary coracoid process transfer between 1977 and 2010 were retrospectively reviewed. Preoperative medical records were queried for demographic data, failure event, and physical examination. Two fellowship-trained shoulder surgeons reviewed radiographs to identify for graft positioning, nonunion, and hardware failure. Descriptive analysis was used to assess reasons for failure. Results: Seventy-five percent of patients sustained a redislocation event after primary coracoid process transfer. Revisions were performed on average 50.3 months after the index procedure, most commonly on males, with two-thirds of recurrent instability occurring during sports. Among all patients, single-screw methods for fixation and inferior graft malposition during index bone block transfer were the most common. Hardware failure and graft nonunion were more frequent with the single-screw technique. Conclusion: In our series, recurrent anterior shoulder instability after primary coracoid process transfer was more likely to occur during sports in young, male patients. The most common technical errors leading to revision were placing the graft inferior to the 5-o’clock position on the glenoid face or relying on single-screw fixation.

Abstract
OBJECTIVES A variety of operative techniques have been described as under the term 'Bristow-Latarjet' procedure. This review aims to define the original procedure, and compare the variation in techniques described in the literature, assessing any effect on clinical outcomes. MATERIALS AND METHODS A systematic review of 24 studies was performed to compare specific steps of the technique (coracoid osteotomy site, subscapularis approach, orientation and position of coracoid graft fixation and fixation method, additional labral and capsular repair) and detect any effect this variability had on outcomes. RESULTS Overall recurrence rate was 5.36% (2.94% to 43%). Half of the studies performed the procedure for recurrent shoulder instability, with only five studies documenting glenoid bone loss as an indication: 12 studies used the procedure as the primary surgical intervention for recurrent instability. No change in outcome was noted when examining variation in the coracoid osteotomy site, the fixation site on the scapular neck, the fixation method or whether a capsular repair was also performed. Performing a horizontal split in subscapularis may preserve external rotation compared with performing a tenotomy. CONCLUSIONS This is the first review to examine various operative techniques of the Bristow-Latarjet procedure, and their effect on outcome. We found that other than the approach through subscapularis, outcome was independent of the surgical technique, and depended more on patient selection. We would commend future publications on this procedure to provide a detailed description of the surgical technique, and as a minimum present rates of recurrence as an outcome measure.

Graft position and fusion rate following arthroscopic Latarjet. Knee Surg Sports Traumatol Arthrosc 2016; 24:507-12.

Abstract
PURPOSE The arthroscopic Latarjet procedure is recently becoming an increasingly popular technique. Nevertheless, position and fusion of the autograft had not been well studied yet. The purpose of this study was to assess the positioning of the coracoid graft and the fusion rate on CT scan in the arthroscopic Latarjet procedure. METHODS The study design was a prospective series of 19 consecutive patients who received arthroscopic Latarjet procedure. Radiological assessment on CT scan performed 3 months post-operatively included an analysis of the fusion and the position of the coracoid bone graft using a validated method. 02:30-04:20 was considered an ideal positioning in the sagittal view. In the axial view, the positioning was considered as flush, congruent, medial, too medial, or lateral. RESULTS The median age of patients was 27.6 (±6.9). Mean operative time was of 161 min ±34.8. The fusion rate was of 78 %. Coracoid grafts were positioned 01:52 h (56° ± 14°) to 4:04 h (122° ± 12.5°). In the axial view, 32 % of the grafts positioning were considered as flush, 38 % as congruent, 30 % as medial, and 6 % too medial. No lateral position was noted. Two complications occurred, one graft fracture during screwing requiring opening conversion and an early case of osteolysis in a medial-positioned graft. CONCLUSION The arthroscopic Latarjet procedure is a technically challenging technique that provides satisfactory fusion rate and graft positioning with a low complication rate. The clinical importance of this study lies in the observation that it is the first study to evaluate the position of the coracoid bone graft in arthroscopic Latarjet according to a detailed and validated method.

Abstract
PURPOSE The purpose of this study was to analyse the learning curve and complication rate of the open Latarjet procedure. METHODS The first 68 Latarjet procedures performed by a single surgeon for chronic anterior shoulder instability were reviewed retrospectively. The standard open surgical technique was followed faithfully during each procedure. Post-operative complications were taken from patient medical records. Post-operative evaluation consisted of clinical and radiological assessments. RESULTS The rate of early (<3 months) clinical complications was 7.4 % (5.9 % haematoma, 1.5 % neurological deficit), and the delayed complication rate was 7.3 %. Early complication rate, duration of surgery (mean 65 min; 35-135) and hospital stay (mean 3 days; 1-4) were significantly reduced as experience increased (respectively; P = 0.03, ρ = - 0.3; P = 0.009, ρ = - 0.3; P < 0.0001, ρ = - 0.6). On the radiographs, the bone block was healed and in perfect position in 87 % of cases, with no effect of surgical experience (P = 0.3, ρ = 0.1). The rate of complications on radiographs was 17 %: 11 % partial lysis, 2 % complete lysis and 4 % non-union. No recurrence of instability was found after an average follow-up of 21 months. CONCLUSION Despite a high rate of post-operative complications, the morbidity of Latarjet procedure remains low. A surgeon's experience significantly affects the surgery duration and the occurrence of early complications. The main radiological complication is partial lysis of the bone block. After a short learning curve, the clinical outcomes of the Latarjet procedure appear to be satisfactory and reproducible. LEVEL OF EVIDENCE IV.
