Pancura D, Licht F, Wong I. Screw Fixation Has Better Outcomes, Lower Incidence of Redislocation, and Lower Bone Resorption Than Button Fixation for Arthroscopic Anatomic Glenoid Reconstruction With Distal Tibia Allograft: A Matched Cohort Analysis. Arthroscopy 2025:S0749-8063(25)00155-0. [PMID: 40056943 DOI: 10.1016/j.arthro.2025.02.034] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/13/2024] [Revised: 02/11/2025] [Accepted: 02/23/2025] [Indexed: 03/25/2025]
Abstract
PURPOSE To compare the clinical outcomes between patients who received arthroscopic anatomic glenoid reconstruction (AAGR) using distal tibia allograft with button fixation versus screw fixation. METHODS A retrospective chart review was conducted for all patients who underwent AAGR with button or screw fixation between 2012 and 2021. Patients were matched at a 1:1 ratio on the basis of sex, type of surgery, and time since surgery. All patients who were included had a minimum clinical follow-up of 2 years. Study outcomes compared Western Ontario Shoulder Instability (WOSI) Index scores, recurrence of instability, incidence of revision surgeries, and computed tomography readings. RESULTS In total, 44 patients were included with 22 patients in each group. The preoperative glenoid bone loss was 22.57 ± 8.06% in the screw group and 22.92 ± 8.84% in the button group (P = .898). Both groups demonstrated a significant improvement in WOSI from preoperative to latest follow-up; however, patients in the screw group demonstrated significantly better WOSI scores at both 2-year (P = .003) and latest follow-up (P = .019) compared with the button group. Recurrent dislocation was observed in 9 patients (40.9%), all of whom underwent button fixation (P < .001). Two patients in the screw group experienced hardware complications (P = .488). Individuals who underwent button fixation were significantly more likely to undergo a revision surgery for recurrent instability (P = .011). Individuals in the button group demonstrated a significantly smaller mean graft anteroposterior diameter postoperatively (P < .001). CONCLUSIONS AAGR with both screw fixation results in significantly improved WOSI scores at minimum 2-year follow-up. Button fixation has a significantly greater incidence of redislocation. Radiographic findings suggest that on average, button fixation results in greater-grade bone resorption and subsequently smaller postoperative glenoid anteroposterior width than screw fixation.

Clinical Outcomes and Recurrence Rates After Arthroscopic Soft Tissue Stabilization With Selective Augmentations for Traumatic Anterior Shoulder Instability in Athletes Versus Non-athletes With Subcritical Glenoid Bone Loss. Cureus 2025; 17:e76930. [PMID: 39906457 PMCID: PMC11791540 DOI: 10.7759/cureus.76930] [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] [Accepted: 01/04/2025] [Indexed: 02/06/2025] Open
Abstract
Introduction Although some studies have reported good outcomes of soft tissue procedures in athletes, to our knowledge, no study has directly compared the clinical outcomes and recurrence rates of soft tissue procedures between athletes and non-athletes. Therefore, we aimed to compare clinical outcomes and recurrence rates between athletes and non-athletes with subcritical glenoid bone defects, who received arthroscopic soft tissue stabilization surgery for traumatic anterior shoulder instability. Methods This retrospective comparative study included patients who received primary arthroscopic shoulder stabilization surgery for traumatic anterior shoulder instability, with a minimum two-year follow-up and a glenoid bone defect <20%. The patients were categorized into athlete or non-athlete groups. For the included patients, we performed one of the following procedures: arthroscopic Bankart repair (ABR), ABR with Hill-Sachs remplissage (HSR), or arthroscopic bony Bankart repair (ABBR). We investigated patient characteristics, including preoperative glenoid and humeral head pathology, and compared the two groups in terms of the Korean Shoulder Score for Instability (KSSI), University of California Los Angeles (UCLA) score, Rowe score, and range of motion (ROM) at two years postoperatively. Postoperative recurrence and reoperation rates were also compared. Results Altogether, 39 non-athletes and 15 athletes were included. Significantly higher KSSI (athletes: 98.00; non-athletes: 94.64; p = 0.012) was observed in the athletes than in the non-athletes. Meanwhile, the UCLA (athletes: 34.33; non-athletes: 33.87; p = 0.370) and Rowe (athletes: 96.67; non-athletes: 96.67; p = 0.460) scores were not significantly different between the two groups. Five (13%) non-athletes and one (7%) athlete experienced postoperative instability recurrence, which was not significantly different (p = 1.000). Fourteen (93%) athletes returned to sports completely after 5.4 months (range, 4-8 months) on average. Conclusion Arthroscopic soft tissue stabilization surgery yielded good clinical outcomes and low recurrence rates in both athletes and non-athletes with subcritical glenoid bone defects.

Abstract
Background This study aimed to evaluate the association between specific, reproducible findings of an anteroinferior capsulolabral complex obtained using conventional 3.0-Tesla nonenhanced magnetic resonance imaging (MRI) and pathologic arthroscopic findings and to assess the confidence level of the findings. Methods Of 125 cases of traumatic anterior instability surgery from January 2017 to November 2019, 66 patients (52 men, 14 women; 23.5 ± 7.9 year old) who underwent conventional 3.0-Tesla MRI at our hospital were reviewed. The following anteroinferior capsulolabral complex features were observed on the T2-star axial image: size difference of the labrum (swelling, diminished), difference in marginal and internal signals (irregularity), and capsule edema image (capsular thickening). We also reviewed fraying, flattening, cracking, and capsular hypertrophy as pathologic arthroscopic findings of the capsulolabral complex. These findings allowed for the simultaneous description of the MRI and arthroscopic evaluations. Three orthopedic surgeons and one radiologist measured the interobserver reliability. We investigated the correlation between the MRI and arthroscopic findings. Results The interobserver reliability of MRI irregularities was low (κ = -0.16), whereas reliability was moderate (κ = 0.554-0.595) for swelling in 22 cases (33%), diminished in 34 cases (52%), and capsular thickness in 40 cases (59%). Labral detachment was found in 26 patients (39%) and fluid collection in 24 patients (36%). The agreement of MRI findings with arthroscopic findings was κ = 0.46 (95% confidence interval [CI]: 0.268-0.654) for swelling to fraying; κ = 0.42 (95% CI: 0.202-0.638) for swelling to capsular hypertrophy; and 0.46 (95% CI: 0.268-0.654) for flattening to diminished. Conclusion The swelling and diminished findings of the anteroinferior capsulolabral complex on conventional MRI were moderately related to pathologic arthroscopic findings in patients with traumatic anterior shoulder instability. These findings contribute to achieving an accurate clinical diagnosis.

Abstract
Background Preoperative computed tomography (CT) evaluation of bone morphometry aids in determining treatment strategies for shoulder instability. The use of zero echo time (ZTE) sequence in magnetic resonance imaging (MRI), a new bone cortex imaging technique, may help reduce radiation exposure and medical costs. Therefore, this study aimed to evaluate the glenoid morphology and detect the presence of bony Bankart lesion using ZTE MRI in shoulders with anterior instability and compare its diagnostic accuracy with that of CT. Methods Thirty-six patients (36 shoulders) with anterior instability who underwent preoperative CT and MRI examinations between April 2019 and October 2021 were retrospectively analyzed. The percentages of glenoid bone defects on 3-dimensional (3D) CT and ZTE images were determined, and the correlation between these percentages was evaluated. The number of cases with bony Bankart lesion on CT and 2 types of ZTE (3D and CT-like) images was determined, and the diagnostic accuracy of ZTE for detecting bony Bankart lesion was assessed, with CT as the gold standard. Patients with bony Bankart lesion on CT images were divided into 2 groups based on whether the lesion was detectable on 3D ZTE or CT-like images. The longer diameters of bony Bankart lesion were compared between the groups. Results The median percentage of glenoid bone loss was 12.1% (range, 1.3%-45.9%) and 12.3% (range, 0%-46.6%) on 3D CT and 3D ZTE images, respectively. The Spearman's rank correlation coefficient was 0.89. Bony Bankart lesion was detected in 18, 13, and 8 shoulders of the 36 patients on CT, 3D ZTE, and CT-like images, respectively. The overall diagnostic accuracy of the CT-like and 3D ZTE images for detecting bony Bankart lesion was 86.1% and 72.2%, respectively. A significant difference was observed between the groups with and without bony Bankart lesion on CT-like images in terms of the long diameter of the bone fragments on CT (P < .01). Conclusion ZTE MRI demonstrated high reproducibility for the evaluation of glenoid bone defect in shoulders with anterior instability. Although no significant difference in the measurement was observed compared with that on CT, the ability of ZTE MRI to delineate bone Bankart lesion remains limited.

Abstract
PURPOSE To investigate and compare the pathologies and clinical outcomes of patients with traumatic anterior shoulder instability who underwent arthroscopic stabilization at 40 years or older between shoulders with initial dislocation before age 40 years and at 40 years or after. METHODS Shoulders that underwent arthroscopic stabilization for recurrent traumatic anterior shoulder instability at 40 years or older with a minimum of 2-year follow-up were included. The subjects were divided into 2 groups according to age at initial dislocation after propensity score matching to reduce potential bias: younger than 40 years (group 1) and 40 years or older (group 2). Radiographic findings, pathologies, clinical outcomes, and complications were compared between the groups. RESULTS Group 1 included 56 shoulders in 56 patients (26 men and 30 women) with a mean age of 51 years (range, 40-77 years). Group 2 included 28 shoulders in 28 patients (13 men and 15 women) with a mean age of 51 years (range, 40-77 years). Glenoid bone loss was greater in group 1 than in group 2 (P = .004). Rotator cuff tears were more frequently observed in group 2 than in group 1 (P < .001). Both groups showed significant improvement in the West Ontario Shoulder Instability Index score (P < .001 for each) and flexion (P < .001 for each). The recurrence rate was 4% in group 1 and 7% in group 2. CONCLUSIONS Rotator cuff tears are significantly more frequent in recurrent shoulder instability patients with initial dislocation at age 40 or older. Arthroscopic stabilization yielded a low recurrence rate and favorable outcomes with a good return-to-sport rate in patients 40 years or older.

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.

Abstract
BACKGROUND The purpose of the present study was to investigate the bone union process after arthroscopic bony Bankart repair (ABBR) in shoulders with a subcritical glenoid defect of 13.5% or larger. METHODS Bone union process after ABBR performed from 2011 to 2018 were retrospectively investigated in 47 athletes younger than 30 years with a subcritical glenoid defect, who underwent CT at least twice postoperatively. The change of bone union between first CT within 6 months and final CT later than 6 months was investigated, especially noticing bone fragment size (≥7.5% versus <7.5%). RESULTS The mean period at first CT and at final CT was 4.1 ± 0.6 months (3-6 months) and 16.8 ± 11.6 months (7-71 months), respectively. From the first to final CT, among 15 shoulders with a small bone fragment (<7.5%), complete union increased from 4 shoulders (26.7%) to 8 shoulders (53.3%), while among 32 shoulders with a large bone fragment (≥7.5%), complete union increased from 15 shoulders (46.9%) to 25 shoulders (78.1%). On the other hand, while non-union or disappeared bone fragment was recognized in 8 shoulders (53.3%) with a small fragment and in 2 shoulders (6.3%) with a large fragment at first CT, it was solely recognized in 4 shoulders (26.7%) with a small fragment and in no shoulders with a large fragment at final CT. While postoperative glenoid fracture at the site of bone union was recognized in 7 shoulders, complete union was finally obtained after conservative treatment in 5 shoulders. So, final complete union was obtained in 9 (60%) of 15 shoulders with a small fragment and in 29 (90.6%) of 32 shoulders with a large fragment (p = 0.021). CONCLUSIONS In shoulders with a subcritical glenoid defect, when a large bone fragment (≥7.5%) was repaired, complete union rate was higher and complete union could be obtained earlier.

Arthroscopic Latarjet yields better union and prevention of instability compared to arthroscopic bony Bankart repair in shoulders with recurrent anterior instability: a systematic review. Knee Surg Sports Traumatol Arthrosc 2023; 31:5994-6005. [PMID: 37980282 DOI: 10.1007/s00167-023-07655-x] [Citation(s) in RCA: 4] [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: 07/27/2023] [Accepted: 10/24/2023] [Indexed: 11/20/2023]
Abstract
PURPOSE To determine whether arthroscopic Latarjet procedure or arthroscopic bony Bankart repair provide better outcomes in terms of rates of recurrent instability, non-union and complications, as well as clinical scores and range of motion. METHODS An electronic literature search was performed using PubMed, Embase®, and Cochrane databases, applying the following keywords: "Arthroscopic bony Bankart" OR "Arthroscopic osseous Bankart" AND "Arthroscopic Latarjet" OR "Arthroscopic coracoid bone block". RESULTS The systematic search returned 1465 records, of which 29 were included (arthroscopic bony Bankart repair, n = 16; arthroscopic Latarjet, n = 13). 37 datasets were included for data extraction, on 1483 shoulders. Compared to arthroscopic Latarjet, arthroscopic bony Bankart repair had significantly higher instability rates (0.14; CI 0.10-0.18; vs 0.04; CI 0.02-0.06), significantly lower union rates (0.63; CI 0.28-0.91 vs 0.98; CI 0.93-1.00), and significantly lower pain on VAS (0.42; CI 0.17-0.67 vs 1.17; CI 0.96-1.38). There were no significant differences in preoperative glenoid bone loss, follow-up, complication rate, ROWE score, ASES score, external rotation, and anterior forward elevation between arthroscopic Latarjet and arthroscopic bony Bankart repair. CONCLUSION Compared to arthroscopic Latarjet, arthroscopic bony Bankart repair results in significantly (i) higher rates of recurrent instability (14% vs 4%), (ii) lower union rates (63% vs 98%), but (iii) slightly lower pain on VAS (0.45 vs 1.17). There were no differences in complication rates, clinical scores, or postoperative ranges of motion. LEVEL OF EVIDENCE IV.

Abstract
BACKGROUND A decrease in the glenoid size after arthroscopic Bankart repair (ABR) was common in shoulders without osseous fragments compared with those with osseous fragments. For cases of chronic recurrent traumatic anterior glenohumeral instability without osseous fragments, we have performed ABR with peeling osteotomy of the anterior glenoid rim (ABRPO) to make an intentional osseous Bankart lesion. The aim of this study was to compare the glenoid morphology after ABRPO with it after simple ABR. METHODS The medical records of patients who underwent arthroscopic stabilization for chronic recurrent traumatic anterior glenohumeral instability were retrospectively reviewed. Patients with an osseous fragment, with revision surgery and without complete data were excluded. Patients were assigned to 1 of 2 groups: Group A, ABR without peeling osteotomy procedure or Group B, with ABRPO procedure. Computed tomography was performed preoperatively and 1 year after surgery. The size of the glenoid bone loss was investigated by the assumed circle method. The following formula was used to calculate the decreased size of the glenoid: (Δ) = (postoperative size of the glenoid bone loss) - (preoperative size of the glenoid bone loss). The size of the glenoid 1 year after surgery was assessed to determine if it had decreased (Δ > 0%) or not decreased (Δ ≤ 0%) relative to the preoperative size. RESULTS This study evaluated 39 shoulders divided into 2 groups: 27 shoulders in Group A and 12 shoulders in Group B. In Group A, postoperative glenoid bone loss was significantly greater than preoperative glenoid bone loss (7.8 ± 6.2 vs. 5.5 ± 5.3, respectively, P = .02). In Group B, postoperative glenoid bone loss was significantly lower than preoperative glenoid bone loss (5.6 ± 5.4 vs. 8.7 ± 4.0, respectively, P = .02). The P value for the interaction of group (A or B) × time (preoperative or postoperative) was 0.001. The decreased size of the glenoid was significantly larger in Group A than in Group B (2.1 ± 4.2 vs. -3.1 ± 4.5, respectively, P = .001). The rate of shoulders in which the size of the glenoid decreased 1 year after surgery relative to the preoperative size was significantly higher in Group A than in Group B (63% [17/27] vs. 25% [3/2], respectively, P = .04). CONCLUSIONS The study showed that ABRPO preserved the glenoid size better than simple ABR without a peeling osteotomy procedure.

Abstract
A displaced anterior glenoid rim fracture, the so-called bony Bankart lesion, occurs after a traumatic shoulder dislocation resulting from a high energy trauma and is associated with recurrent shoulder instability. Different surgical techniques have been described in the literature to address this pathology, including open reduction and fixation, as well as arthroscopic transosseous, and single-row or double-row approaches with the use of suture anchors. However, there is currently no gold standard of treatment and the stability of fixation and the healing of the bony fragment are still a concern. The purpose of this report was to introduce an arthroscopic independent double-row (IDR) bony Bankart repair technique for fixation of large glenoid fractures.

Abstract
Background To investigate the characteristics of glenoid rim morphology in young athletes (<40 yr) with unstable painful shoulder. Methods This was a retrospective case series. The inclusion criteria were as follows: (1) shoulder pain during sports activity, (2) traumatic onset, (3) no complaint of shoulder instability, and (4) soft tissue or bony lesions confirmed on imaging examinations (computed tomography and magnetic resonance imaging). The above-mentioned painful cohort was then compared (in a 2:1 ratio) to a match-paired control group of patients with similar demographics but with frank anterior glenohumeral instability as defined by imaging and physical findings. The pain (not apprehension) was reproduced during the anterior apprehension test in supine position and relieved by relocation test in all patients. Glenoid rim morphology, bone union in shoulders with a fragment-type glenoid, glenoid defect size, bone fragment size, medial displacement of bone fragments (MDBF), and medial distance of erosion (MDE) were compared between painful shoulders and unstable shoulders. Results There were 79 painful shoulders and 165 unstable shoulders. The glenoid rim morphology was normal in 33 shoulders, erosion-type in 15 shoulders, and fragment-type in 31 shoulders among painful shoulders, whereas the respective shoulders were 19, 33, and 113 among unstable shoulders (P < .001). Bone union was complete in 15 shoulders, partial in 14 shoulders, and nonunion in 2 shoulders among painful shoulders, whereas the respective shoulders were 43, 31, and 39 among unstable shoulders (P = .001). The mean glenoid defect size was 6.0 ± 7.2% and 12.7 ± 7.4%, respectively (P < .001), and the mean bone fragment size was 5.8 ± 6.4% and 5.4 ± 4.6%, respectively, (P = .591). The mean MDBF was 1.4 ± 1.5 mm and 3.0 ± 2.2 mm, respectively (P < .001), and the mean MDE was 2.3 ± 1.2 mm and 5.2 ± 2.4 mm, respectively (P < .001). In shoulders with a smaller glenoid defect (<13.5%), the prevalence of shoulders with MDBF (<2 mm) and shoulders with MDE (<2 mm) was more frequent in painful shoulders. On the other hand, in shoulders with a larger glenoid defect (≥13.5%), erosion-type glenoid, nonunion in fragment-type glenoid and bone fragment smaller than 7.5% was not recognized in painful shoulders. Shoulders with MDBF (<2 mm) were significantly more frequent in painful shoulders (P = .009). Conclusions In painful shoulders normal or erosion-type glenoid was predominant, and glenoid defect size was significantly smaller than unstable shoulders. On the other hand, a large bone fragment (≥7.5%) remained and united completely or partially in all shoulders with a larger glenoid defect (≥13.5%). Bone union was obtained within 2 mm from the articular surface in most of them.

Abstract
Background Determining the magnitude of glenoid bone loss in patients with anterior shoulder instability is an important step in guiding management. Most calculations to estimate the bone loss do not include the bony Bankart fragment. However, if it can be reduced and adequately fixed, the estimation of bone loss may be decreased. Purpose To derive a simple equation to calculate the surface area of the bony fragment in Bankart fractures. Study Design Case series; Level of evidence, 4. Methods A total of 26 patients suspected of having clinically significant bone loss underwent computed tomography imaging preoperatively, and the percentage of glenoid bone loss (%BL) was approximated with imaging software using a freehand region of interest area measurement with and without the inclusion of the bony Bankart fragment. By assuming this bony fragment as a hemi-ellipse with height, H, and thickness, d, we represented the surface are of the bony piece (Abonefragment=πHd4), and subtracted it from the overall %BL. They compared this value with the one found using imaging software. Results Without the inclusion of the bony Bankart, the overall %BL by the standard true-fit circle measured using imaging software was 23.8% ± 9.7%. When including the bony Bankart, the glenoid %BL measured using imaging software was found to be 12.1% ± 8.5%. The %BL calculated by our equation with the bony Bankart included was 10% ± 11.1%. There was no statistically significant difference between the %BL values measured using the equation and the imaging software (P = .46). Conclusion Using a simple equation that approximates the bony Bankart fragment as a hemiellipse allowed for estimation of the glenoid bone loss, assuming that the fragment can be reduced and adequately fixed. This method may serve as a helpful tool in preoperative planning when there are considerations for incorporating the bony fragment in the repair.

Abstract
Background With recurrent anterior instability the bone fragment of a bony Bankart lesion is often small compared to the glenoid defect. The purpose of the present study was to clarify the changes to both the bone fragment and glenoid defect over time in a single subject. Methods Participants were patients who underwent computed tomography (CT) at least twice after an instability event between 2004 and 2021 and had a fragment-type glenoid at first CT. The glenoid rim width (A), glenoid defect width (B), and bone fragment width (C) were measured in millimeters. If B or C increased by 1 mm or more from the first to final CT, the change was judged as "enlarged," and if B or C decreased by 1 mm or more, it was judged as "reduced"; all other cases were judged as "similar." Then, glenoid defect size and bone fragment size were calculated as B/A×100% and C/A×100%, respectively, and the changes from the first to final CT were compared. Results From the first to final CT, the glenoid defect was enlarged in 30 shoulders, similar in 13 shoulders, and reduced in 4 shoulders, and the bone fragment was enlarged in 18 shoulders, similar in 24 shoulders, and reduced in 5 shoulders. The mean glenoid defect size significantly increased from 10.9% to 15.3% (P < .001), and the mean bone fragment size increased from 6.4% to 7.8%, respectively (P = .005). At the final CT, in 6 shoulders a new glenoid fracture was observed at a different site from the original fracture. When they were excluded from the analyses, the mean glenoid defect size still significantly increased (from 11.2% to 15.2%; P < .001), but the mean bone fragment size did not (6.5% vs. 7.3%, respectively; P = .088). Conclusions In shoulders with recurrent anterior instability, glenoid defect size appears to increase significantly over time, whereas the bone fragment size remains unchanged or increases only slightly. Bone fragment resorption is quite rare, and a bone fragment appears to be small because of an enlarged glenoid defect.

Direction of non-recoverable strain in the glenohumeral capsule following multiple anterior dislocations: Implications for anatomic Bankart repair. J Orthop Res 2023; 41:479-488. [PMID: 35615943 DOI: 10.1002/jor.25385] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/23/2021] [Revised: 05/05/2022] [Accepted: 05/14/2022] [Indexed: 02/04/2023]
Abstract
The study aimed to analyze the direction of non-recoverable strain and determine the optimal direction for anatomic capsular plication within four sub-regions of the inferior glenohumeral capsule following multiple dislocations. Seven fresh-frozen cadaveric shoulders were dissected. A grid of strain markers was affixed to the inferior glenohumeral capsule. Each joint was mounted in a 6-degree-of-freedom robotic testing system and repeatedly dislocated in the anterior direction 10 times at 60° of abduction and 60° of external rotation of the glenohumeral joint. The 3D positions of the strain markers were compared before and after dislocations to define the non-recoverable strain. The strain map was divided into four sub-regions. The angles of deviation between each maximum principle strain vector and the anterior band of the inferior glenohumeral ligament (AB-IGHL) or posterior band of the IGHL (PB-IGHL) for the anterior and posterior regions of the capsule were determined. The mean direction of all strain vectors in each sub-region was categorized. The direction of the non-recoverable strain in the anterior-band and anterior-axillary-pouch sub-regions was categorized as parallel to the AB-IGHL, whereas the posterior-axillary-pouch and posterior-band sub-regions were mostly perpendicular to the PB-IGHL. Clinical Significance: Plication of the anteroinferior capsule parallel to the AB-IGHL may be preferred during arthroscopic Bankart repair to restore anatomy; posteroinferior capsular plication may also be necessary and best performed perpendicular to the PB-IGHL. The direction of the capsular injury remains the same irrespective of the number of dislocations. This study provides the scientific and quantitative rationale for an anatomic approach to capsular plication.

Abstract
BACKGROUND The purpose of the present study was to retrospectively evaluate new bone formation after arthroscopic Bankart repair (ABR) and the influence of new bone formation on recurrence in shoulders with an erosion-type glenoid defect. METHODS We analyzed data on shoulders with an erosion-type glenoid defect. Participants were patients who underwent computed tomography to evaluate new bone formation after ABR performed from 2004 to 2021 and were followed for a minimum of 2 years. We investigated the factors influencing new bone formation, in particular the presence of an intraoperative bone fragment, and the influence of new bone formation and its size on postoperative recurrence. RESULTS A total of 100 shoulders were included. The mean glenoid defect size was 10.1% ± 6.3% (range, 1.2%-31.5%). New bone formed postoperatively in 15 shoulders (15.0%) and was seen in significantly more shoulders with an intraoperative bone fragment (11 of 18, 61.1%) than in those without a fragment (4 of 82, 4.9%; P < .001). Recurrence occurred in 22 shoulders (22.0%), and the rate of recurrence was not different between shoulders with new bone formation (3 of 15, 20.0%) and without new bone formation (19 of 85, 22.4%; P = .999). Among the 15 shoulders with new bone formation, the size of the new bone fragments relative to glenoid width was <5% in 2 shoulders, 5%-<7.5% in 8 shoulders, 7.5%-<10% in 3 shoulders, and ≥10% in 2 shoulders; in all 3 shoulders with postoperative recurrence, the relative size was <7.5%. CONCLUSIONS Even in shoulders with an erosion-type glenoid defect, new bone may form after ABR, especially in shoulders with an intraoperative bone fragment. However, new bone formation does not decrease the rate of postoperative recurrence.

Abstract
BACKGROUND Being younger than 20 years of age at the time of arthroscopic Bankart repair (ABR) is known to be one of the most important risk factors for postoperative recurrence of instability. When deciding on the appropriate surgical approach, surgeons generally consider only the size of a critical glenoid defect, and most of them do not take into account factors such as the size of bone fragments and possible bone union after arthroscopic bony Bankart repair (ABBR). Therefore, this retrospective study aimed to clarify the risk factors for postoperative recurrence after ABR in teenage competitive athletes by focusing on glenoid rim morphologies and bone union. METHODS Participants were 115 teenage competitive athletes without a capsular injury who underwent primary ABR for chronic traumatic anterior instability and were followed up for a minimum of 2 years. Possible risk factors for postoperative recurrence were investigated by univariate and multivariate analysis. In shoulders with a glenoid defect and bone fragment, the influence of glenoid defect size and bone fragment size on bone union after ABBR was also investigated. RESULTS Postoperative recurrence was seen in 16 patients (13.9%). Regarding glenoid defect size, recurrence was seen in 1 (3.2%) of 31 shoulders with a glenoid defect smaller than 5% (including those with a normal glenoid), 15 (22.1%) of 68 shoulders with a glenoid defect of 5%-20%, and 0 (0%) of 16 shoulders with a glenoid defect of 20% or larger (P = .009). Regarding bone union, recurrence was seen in 4 (6.9%) of 58 shoulders with complete or partial bone union after ABBR and 8 (40%) of 20 shoulders with nonunion or disappearance of the bone fragment (P = .001). Regarding bone fragment size, recurrence was seen in 12 (20.7%) of 58 shoulders with a small or no bone fragment (<7.5%) and in 3 (8.6%) of 35 shoulders with a large bone fragment (≥7.5%; P = .154). Multivariate analysis identified non-union or disappearance of the bone fragment after ABBR as a significant risk factor for recurrence. Complete or partial bone union was seen in 25 (58.1%) of 43 shoulders with a small bone fragment (<7.5%) and 33 (94.3%) of 35 shoulders with a large bone fragment (≥7.5%; P < .001). CONCLUSIONS In teenage competitive athletes, bone union after ABBR affects postoperative recurrence after ABR, regardless of the preoperative glenoid defect size, and bone union rate after ABBR is significantly influenced by bone fragment size.

Abstract
Background Recent studies reported that anterior glenoid rim erosion can occur in the early period after arthroscopic Bankart repair (ABR) for traumatic anterior shoulder instability. However, it is unknown whether such erosion is a risk factor for postoperative recurrence. This study evaluated risk factors for postoperative recurrence after ABR, specifically aiming to elucidate whether reduction of postoperative glenoid width due to anterior glenoid rim erosion is one of such factors. Methods A total of 220 shoulders that underwent ABR alone between 2013 and 2020 were retrospectively investigated. Patient age at surgery, whether the patient was a collision/contact athlete, anchor placement, preoperative glenoid bone defect (%), localization of the Hill-Sachs lesion, and change of glenoid width (%) in the 6 months after surgery were investigated for their statistical relation to recurrence by univariate and multiple logistic regression analysis. Results Postoperative recurrence occurred in 32 of 220 shoulders (14.5%). In univariate analysis, being a collision/contact athlete was the only variable with a significant effect on recurrence (odds ratio [OR], 2.555; 95% confidence interval [CI], 1.123-5.814; P = .03). Change of glenoid width reduction was larger in those with recurrence than without recurrence, but the difference was not statistically significant (-7.0 ± 6.6% vs. -5.0 ± 9.3%; P = .14). However, in multivariate logistic analysis, preoperative glenoid bone defect (%) (adjusted unit OR, 1.076; 95% CI, 1.018-1.137; P = .010) and postoperative change of glenoid width (%) (adjusted unit OR, 0.946; 95% CI, 0.900-0.994; P = .028) had a significant influence on postoperative recurrence. Conclusion Glenoid width reduction due to anterior glenoid rim erosion after ABR is a risk factor for recurrence.

Abstract
Operative treatment of anterior glenohumeral instability is challenging, particularly with the presence of an anterior glenoid rim fracture, also called an "osseous Bankart lesion." Successful reduction and fixation of the lesion has been shown to greatly reduce the risk of recurrent dislocations while achieving osseous union and normalization of glenoid anatomy1. Description The current surgical video article outlines a technique for an osseous Bankart repair in a patient with a displaced fracture as well as substantial pain and instability. First, the amount of bone loss is measured on 3-dimensionally reconstructed computed tomography (CT) imaging, with the humeral head digitally subtracted2. The procedure is then performed arthroscopically with the patient in the lateral decubitus position. A diagnostic evaluation, beginning with posterior and anterior portal placement in the rotator interval, is completed to assess any rotator cuff injury and the extent of labral tearing and osseous displacement. Next, the bone fragment is elevated into its anatomical position. This fragment is then reduced with use of a double-row suture technique, followed by concomitant capsulolabral repair. Alternatives Nonoperative treatment with a sling can be utilized as long as post-reduction CT scans reveal anteroposterior centering of the humeral head on the glenoid3. Rehabilitation can include active-assisted and passive glenohumeral mobilization, as well as daily pendulum exercises and physiotherapy. Rationale Osseous Bankart repair has been shown to effectively improve patient-reported outcomes and normalize glenoid morphology1,3,4. Failure to recognize and appropriately treat an osseous Bankart fracture may lead to osseous erosion caused by repetitive episodes of subluxations or dislocations, along with substantial pain and weakness5. Indications for arthroscopic Bankart repair include young, active patients with a reducible fracture fragment, an anterior glenoid deficit of >10%, and a history of failed nonoperative treatment3-8. Expected Outcomes Clinical outcomes following the osseous Bankart repair procedure have been shown to be highly successful, with high rates of return to sport, minimal reduction in range of motion, and restoration of shoulder function and stability4. Additionally, long-term follow-up has shown successful osseous union and normalization of glenoid anatomy1. Important Tips Apply tension to sutures with a suture retriever before the PushLock anchors (Arthrex) are placed during fracture reduction.Utilize a trans-subscapularis portal for anchor placement medial to the fracture on the glenoid neck.Perform adjustable tensioning during labral repair with knotless all-suture anchors.Utilize a lateral distraction device with the patient in the lateral decubitus position to completely visualize the anteroinferior glenoid.Chronic onset and late intervention may cause difficulties in the reduction of the bone fragment.Suture management may be difficult, particularly for surgeons at an early stage of the learning curve.A defect that is wide (from medial to lateral) may be difficult to maneuver around and reduce.

Abstract
BACKGROUND Individual studies reporting the clinical outcomes of arthroscopic bony Bankart repair for anterior shoulder instability have reported excellent results but have been limited by their small sample sizes. No systematic review of the literature has been performed examining the clinical outcomes of arthroscopic bony Bankart repair. PURPOSE To provide a systematic review of the literature to examine the functional outcomes, recurrence rate, and return to sports rate after arthroscopic bony Bankart repair for anterior instability of the shoulder. STUDY DESIGN Systematic review; Level of evidence, 4. METHODS A systematic review of the literature based on the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines was conducted using the Cochrane Database of Systematic Reviews, Ovid/Embase, PubMed, and Web of Science. Studies that examined clinical outcomes after arthroscopic bony Bankart repair for anterior shoulder instability were included. Data pertaining to study characteristics and design, patient demographic characteristics, and clinical results, including functional outcomes, recurrence rate, and return to sports, were collected. The results from the studies were pooled, and weighted means and overall rates were calculated. RESULTS In total, 21 studies with 769 patients were included for analysis. Most patients were male (91.7%), the mean age was 26.7 years (range, 12-71 years), and the mean follow-up was 42.7 months (range, 6-120 months). The most commonly reported functional outcome score was the Rowe score (12 studies), which improved on average from 41.9 preoperatively to 90.8 postoperatively. The rate of recurrent instability was reported by all 21 studies, and the overall recurrence rate was 11.9% (88/738). Return to sports after arthroscopic bony Bankart repair was reported by 11 studies, with a pooled return to sports rate of 91.0% (264/290). CONCLUSION Arthroscopic bony Bankart repair for anterior shoulder instability resulted in improvements in functional outcomes, a low rate of recurrent instability, and a high rate of return to sports. Although these findings are extremely promising, future prospective studies with larger sample sizes are needed to further evaluate the clinical outcomes of arthroscopic bony Bankart repair.

Abstract
Objective To evaluate the efficacy of the double‐row and double‐pulley technique in treating anterior shoulder glenoid fracture (Ideberg type Ia) using shoulder arthroscopy. Methods Thirty‐six patients with Ideberg type Ia admitted from March 1, 2017, to March 1, 2020, were retrospectively reviewed. Data of the patients' history included age, sex, side of the affected arm, the mean time from injury to surgery, the surgical duration, the average blood loss, and the average total duration of hospital stay. The double‐row and double‐pulley technique was used to repair the scapular glenoid fracture under arthroscopy. Computed tomography (CT) was used to evaluate fracture healing after surgery. The American Shoulder and Elbow Surgeons (ASES) score, the University of California at Los Angeles (UCLA) shoulder joint scoring system, and the Constant–Murley shoulder function score were used to assess the function of the affected shoulder. Results The surgical duration was 90–150 min, with a mean of 127 min. The average blood loss was 90 mL (range, 60–120 mL), and the average total duration of hospital stay was 9.2 days (range, 3 to 14 days). At 9 months after surgery, the CT results showed that all fractures healed, and all patients returned to their previous levels of activity and regained an excellent range of motion. The visual analog scale (VAS) score was 7.55 ± 1.32 before surgery, and the VAS score significantly decreased to 1.24 ± 0.72 at 12 months after the operation (p < 0.05). The Constant, ASES, and UCLA shoulder function scores were 44.38 ± 2.16, 43.47 ± 12.76, and 21.80 ± 1.16 before the surgery, respectively, which improved to 93.52 ± 2.82, 91.34 ± 8.28, and 33.24 ± 1.64, respectively, in the following 12 months. One patient experienced fat liquefaction. However, no cases of deep venous thrombosis, iatrogenic neurovascular compromise, wound infection, or neurovascular injury were identified. Conclusion The double‐row and double‐pulley technique for treating Ideberg type Ia under shoulder arthroscopy has minor surgical trauma, reliable fracture reduction and fixation, less postoperative pain, and fewer postoperative complications and significantly improves the patient's shoulder joint function.

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.

On-the-Edge Anchor Placement May Be Protective Against Glenoid Rim Erosion After Arthroscopic Bankart Repair Compared to On-the-Face Anchor Placement. Arthroscopy 2022; 38:1099-1107. [PMID: 34715278 DOI: 10.1016/j.arthro.2021.10.013] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/18/2021] [Revised: 10/11/2021] [Accepted: 10/11/2021] [Indexed: 02/02/2023]
Abstract
PURPOSE This retrospective study aimed to compare the effects of 2 different anchoring placements on glenoid rim erosion after arthroscopic Bankart repair (ABR). METHODS Shoulders that underwent ABR from January 2013 to July 2020 were divided into 2 groups according to anchor placement (on-the-face, group F; on-the-edge, group E). We retrospectively calculated the percent change of glenoid width (Δ) on the first postoperative computed tomography scan (CT; performed within 6 months) and second postoperative CT (performed at 6 to 12 months) relative to the width on the preoperative CT and compared percent changes between the 2 groups. Also, we investigated the influence of preoperative glenoid structures (normal, erosion, bony Bankart) and the postoperative recurrence rate. RESULTS We examined 225 shoulders in 214 patients (group F, n = 151; group E, n = 74). At first CT, anchoring placement was significantly associated with postoperative decrease of glenoid width (group F, -7.6% ± 7.9%; group E, -0.1% ± 9.7%; P < .0001). The difference between groups F and E was significant in shoulders with a preoperative glenoid defect (bony Bankart, -6.6% ± 8.8% vs 2.5% ± 11.2%, respectively; P < .0001; erosion, -6.6% ± 6.2% vs -2.6% ± 5.3%, respectively; P = .03). In 112 shoulders, CT was performed twice; Δ was -6.9% ± 7.3% in group F (n = 64) and -1.7% ± 10.1% in group E (n = 48; P = .005) at the first CT and -3.2% ± 10.0% and 1.0% ± 10.6% (P = .10), respectively, at the second CT, indicating recovery of glenoid width in both groups. The postoperative recurrence rate in patients with at least 2 years' follow-up was 14.7% in group F and 14.6% in group E. CONCLUSIONS In the early stage after ABR, on-the-edge glenoid anchor placement was associated with less glenoid rim erosion than on-the-face anchor placement. LEVEL OF EVIDENCE Level III, retrospective comparative trial.

Abstract
PURPOSE To investigate bone union and postoperative recurrence after arthroscopic bony Bankart repair (ABBR) in male competitive rugby and American football players with a subcritical glenoid defect of ≥13.5% and to compare findings with those in players with a glenoid defect of <13.5%. METHODS Participants were male competitive rugby or American football players with a glenoid defect and bone fragment who underwent ABBR from July 2011 to December 2018 and were followed for a minimum of 2 years. We investigated the influence of glenoid defect and bone fragment size on bone union and postoperative recurrence after ABBR. RESULTS We included 45 rugby players and 35 American football players. A total of 38 shoulders were assigned to the small defect group (<13.5%) and 42 to the large defect group (≥13.5%). The complete bone union rate was 47.4% in the small defect group and 71.4% in the large defect group (P = .040), and postoperative recurrence was seen in 13 (34.2%) and 5 shoulders (11.9%), respectively (P = .030). In the small defect group, the bone fragment size was <7.5% in 30 shoulders and ≥7.5% in 8 shoulders; in comparison, the respective numbers were 12 and 30 shoulders in the large defect group, and large fragments (>7.5%) were significantly more common in this group (P < .001). The complete union rate was significantly higher in shoulders with a large fragment (≥7.5%) than in those with a small fragment (<7.5%; 78.9% versus 42.9%, respectively; P = .001). The recurrence rate was 33.3% in shoulders with a small fragment (<7.5%) and 10.5% in shoulders with a large fragment (≥7.5%; P = .017) and was significantly lower in shoulders with a complete union than in those without a complete union (6.3% versus 46.9%, respectively; P < .001). CONCLUSION The postoperative recurrence rate after ABBR was lower in male competitive rugby and American football players with a large glenoid defect (≥13.5%) than in those with a small glenoid defect (<13.5%) and might be associated with a higher rate of complete bone union of the resultant large bone fragment (≥7.5%). LEVEL OF EVIDENCE III, case-control study.

Abstract
Much is discussed about the limits of the treatment of anterior shoulder instability by arthroscopy. The advance in understanding the biomechanical repercussions of bipolar lesions on shoulder stability, as well as in the identification of factors related to the higher risk of recurrence have helped us to define, more accurately, the limits of arthroscopic repair. We emphasize the importance of differentiation between glenoid bone loss due to erosion (GBLE) and glenoid edge fractures, because the prognosis of treatment differs between these forms of glenoid bone failure. In this context, we understand that there are three types of bone failure: a) bone Bankart (fracture); b) combined; and c) glenoid bone loss due to anterior erosion (GBLE), and we will address the suggested treatment options in each situation. Until recently, the choice of surgical method was basically made by the degree of bone involvement. With the evolution of knowledge, the biomechanics of bipolar lesions and the concept of glenoid track , the cutoff point of critical injury, has been altered with a downward trend. In addition to bone failures or losses, other variables were added and made the decision more complex, but a little more objective. The present update article aims to make a brief review of the anatomy with the main lesions found in instability; to address important details in arthroscopic surgical technique, especially in complex cases, and to bring current evidence on the issues of greatest divergence, seeking to guide the surgeon in decision making.

Abstract
BACKGROUND A preoperative glenoid defect of 13.5% or larger is recognized as a subcritical glenoid defect at arthroscopic Bankart repair (ABR) for collision/contact athletes or military personnel. PURPOSE To clarify the prevalence and size of remaining bone fragments in shoulders with a subcritical glenoid defect at recurrent anterior instability and to investigate the influence on postoperative recurrence after ABR for younger competitive athletes. STUDY DESIGN Cohort study; Level of evidence, 4. METHODS The study included 96 shoulders with recurrent instability that underwent ABR between July 2011 and March 2018 for shoulders with a subcritical glenoid defect. The patients were divided into 2 groups according to the glenoid defect size (13.5%-<20%, medium; ≥20%, large). The bone fragment size in each defect group was retrospectively investigated and classified into 4 groups (no, 0%; small, >0%-<5%; medium, 5%-<10%; large, ≥10%). The postoperative recurrence rate for each combination of glenoid defect size and bone fragment size was investigated for competitive athletes aged <30 years. The fragments, when present, were repaired to the glenoid. RESULTS The glenoid defect size was 13.5%-<20% in 60 shoulders (medium defect group) and ≥20% in 36 shoulders (large defect group). The mean bone fragment size was 6.7% ± 5.1% and 8.9% ± 4.9%, respectively (P = .042). In the medium defect group, there were 15 shoulders (25%) without a bone fragment, 6 shoulders (10%) with a small fragment, 23 shoulders (38.3%) with a medium fragment, and 16 shoulders (26.7%) with a large fragment. In the large defect group, the respective numbers were 2 shoulders (5.6%), 6 shoulders (16.7%), 14 shoulders (38.9%), and 14 shoulders (38.9%). A medium or large bone fragment was more common in the large defect group (P = .252). Among 64 younger competitive athletes who underwent ABR with a minimum of 2 years of follow-up, postoperative recurrence was recognized in 7 of 38 (18.4%) athletes in the medium defect group, but it was not recognized in any of the 26 athletes in the large defect group (P = .036). Postoperative recurrence was recognized in 4 of 12 (33.3%) athletes with a small fragment or no fragment and in 3 of 52 (5.8%) athletes with a medium or large fragment (P = .019). CONCLUSION A larger bone fragment frequently remained in shoulders with a subcritical glenoid defect at recurrent instability. The postoperative recurrence rate after ABR for younger competitive athletes was low when a remaining larger bone fragment was repaired.

[PMID: 34541013 PMCID: PMC8447097 DOI: 10.1177/23259671211029239] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/13/2021] [Accepted: 03/02/2021] [Indexed: 11/23/2022] Open
Abstract
Background: A “double-pulley” dual-row technique had been applied for arthroscopic
fixation of large bony Bankart lesion in which the fragment has a wide
base. Purpose: To investigate clinical outcomes and glenoid healing after arthroscopic
fixation of bony Bankart lesion using the double-pulley dual-row
technique. Study Design: Case series; Level of evidence, 4. Methods: A total of 25 patients were included in this retrospective study. The
American Shoulder and Elbow Surgeons (ASES) score, pain visual analog scale
(VAS) score, and range of motion of the affected shoulder were assessed.
Radiographs and computed tomography (CT) scans (preoperatively, immediately
after surgery, and at 1 year postoperatively) were performed to evaluate
arthritic changes (Samilson-Prieto classification) and glenoid size. The
intraobserver reliability of the CT measurements was analyzed. Results: At a mean follow-up of 3.4 years, the mean ASES and VAS scores were 94.87 ±
5.02 and 0.48 ± 0.59, respectively. Active forward elevation, external
rotation with the arm at the side, and internal rotation were 165.80° ±
11.70°, 33.20° ± 8.02°, and T9 (range, T6-S1), respectively. No patient
reported a history of redislocation or instability. The intraobserver
reliability of the CT measurements was moderate to excellent. The mean
preoperative size of the bony fragment was measured as 23.4% ± 7.8% of the
glenoid articular surface. The quality of the reduction was judged to be
excellent in 13 (52%) cases, good in 8 (32%), and fair in 4 (16%). The mean
immediate postoperative glenoid size was 96.8% ± 4.3%, and bone union was
found in all cases. There were no significant differences between
reconstructed and immediate postoperative glenoid size or between
preoperative and final Samilson-Prieto grades. Conclusion: The arthroscopic double-pulley method was a reliable technique for the
fixation of large bony Bankart lesions with a wide base. Satisfactory
results can be expected regarding the restoration of the glenoid morphology
and stability of the shoulder. High healing rate and good shoulder function
can be achieved. No radiological evidence of cartilage damage caused by
suture abrasion was found at 2- to 5-year follow-up.

Arthroscopic Iliac Bone Grafting for Traumatic Anterior Shoulder Instability With Significant Glenoid Bone Loss Yields Low Recurrence and Good Outcome at a Minimum of Five-Year Follow-Up. Arthroscopy 2021; 37:2399-2408.

Abstract
PURPOSE The purpose of this study was to investigate the clinical and radiographic outcomes of arthroscopic iliac bone grafting with capsulolabral reconstruction for severe glenoid bone loss with a minimum of 5 years' follow-up. METHODS The inclusion criterion was shoulders that underwent arthroscopic iliac bone grafting for >20%-25% glenoid defect between January 2007 and April 2014, and the exclusion criterion was <5 years' follow-up. Iliac crest bone grafts of approximately 2.0 cm length and 0.8 cm height were arthroscopically fixed to the anterior glenoid using 2 cannulated screws followed by capsulolabral repair. Rowe score, Western Ontario Shoulder Instability Index (WOSI), and passive range of motion were evaluated. Radiographic findings including the Kellgren and Lawrence osteoarthritis grade and graft integration on 3-dimensional computed tomography at the final follow-up were also evaluated. RESULTS Forty-eight shoulders met the inclusion criteria, and 24 shoulders with ≥5 years' follow-up were included (1 died; 23 were lost follow-up): 22 males, 2 females; a mean age at surgery, 30 years (range, 18-52 years); a mean follow-up of 8 years (range, 5-11 years). The mean preoperative glenoid bone defect was 22% (range, 20%-28%). All shoulders had a Hill-Sachs lesion including 4 on-track lesions. One shoulder experienced traumatic redislocation at 5 years after surgery. The scores significantly improved: Rowe score, 19 ± 8 to 94 ± 8 (P < .001); WOSI, 1547 ± 241 to 439 ± 318 (P < .001). Postoperative flexion showed significant improvement from 158 ± 18 to 169 ± 11 (P = .008), whereas internal rotation deteriorated from T8 ± 3 to T10 ± 3 (P = .005). Graft integration showed remodeling in 54% and excessive absorption in 13%. Osteoarthritis grades progressed significantly (P < .001), but only grade 1 osteoarthritic changes were seen, except for 4 shoulders with grade 2 osteoarthritis. CONCLUSIONS Arthroscopic iliac bone grafting for traumatic anterior shoulder instability with severe glenoid bone loss yielded satisfactory outcomes with mid-term follow-up. Arthritic changes progressed in half of the shoulders; however, most shoulders only demonstrated grade 1 osteoarthritis. LEVEL OF EVIDENCE Level IV, therapeutic case series.

[PMID: 33581303 DOI: 10.1016/j.arthro.2021.01.061] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [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.

Arthroscopic Bankart Repair and Open Bristow Procedure in the Treatment of Anterior Shoulder Instability With Osseous Glenoid Lesions in Collision Athletes. Orthop J Sports Med 2021; 9:23259671211008274. [PMID: 34104661 PMCID: PMC8165538 DOI: 10.1177/23259671211008274] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/20/2020] [Accepted: 12/21/2020] [Indexed: 12/12/2022] Open
Abstract
Background: Traumatic anterior shoulder instability in collision sports athletes often involves osseous glenoid lesions, which make surgical treatment challenging. High redislocation rates have been seen in collision sports athletes treated using arthroscopic Bankart repair. Purpose: To investigate the effectiveness of a combined arthroscopic Bankart repair and open Bristow procedure for the treatment of traumatic anterior shoulder instability in collision sports athletes, with a focus on osseous glenoid lesions. Study Design: Case series; Level of evidence, 4. Methods: We reviewed 149 shoulders in 141 competitive collision sports athletes (mean ± standard deviation age, 20.1 ± 4.1 years; 8 bilateral cases) who underwent a combined arthroscopic Bankart repair and open Bristow procedure with minimum 2 years of follow-up. Osseous Bankart lesions were arthroscopically reduced and fixed using a coracoid graft. Results: Clinical outcomes as indicated by mean Rowe score improved significantly from 50.0 preoperatively to 98.9 postoperatively (P < .001) at a median follow-up of 3.4 years (range, 2.5-7 years). There were 2 recurrent dislocations (1.3%), both of which had nonunion of the transferred coracoid. Osseous Bankart lesions were observed in 85 shoulders, and osseous glenoid lesions ≥10% of the diameter of the nonoperative side were found in 58 shoulders, including 24 off-track cases. Clinical outcomes were not significantly different between patients with a glenoid defect ≥10% and <10%. Nonunion of the transferred coracoid was observed in 16 shoulders (10.7%), which had inferior Rowe scores; however, we could not define any risk factors for nonunion, including patient characteristics or bone morphology. Postoperative computed tomography performed in 29 patients >1 year after surgery showed successful repair of the osseous glenoid lesions, with a restored glenoid articular surface in all cases. Significant pre- to postoperative increases were seen in glenoid diameter (mean, 13.1% [95% CI, 9.9%-16.3%]; P < .001) and area (mean, 10.6% [95% CI, 8.5%-12.7%]; P < .001). Conclusion: A combined arthroscopic Bankart repair and open Bristow procedure improved bone morphology and was a reliable surgical method for treating collision sports athletes with traumatic anterior shoulder instability involving osseous glenoid lesions.

Abstract
Background: In shoulders with traumatic anterior instability, a bipolar bone defect has been recognized as an important indicator of the prognosis. Purpose: To investigate bipolar bone defects at primary instability and compare the difference between dislocation and subluxation. Study Design: Cohort study; Level of evidence, 3. Methods: There were 156 shoulders (156 patients) including 91 shoulders with dislocation and 65 shoulders with subluxation. Glenoid defects and Hill-Sachs lesions were classified into 5 size categories on 3-dimensional computed tomography (CT) scans and were allocated scores ranging from 0 (no defect) to 4 points (very large defect). To assess the combined size of the glenoid defect and Hill-Sachs lesion, the scores for both lesions were summed (range, 0-8 points). Patients in the dislocation and subluxation groups were compared regarding the prevalence of a glenoid defect, a bone fragment of bony Bankart lesion, a Hill-Sachs lesion, a bipolar bone defect, and an off-track Hill-Sachs lesion. Then, the combined size of the bipolar bone defects was compared between the dislocation and subluxation groups and among patients stratified by age at the time of CT scanning (<20, 20-29, and ≥30 years). Results: Hill-Sachs lesions were observed more frequently in the dislocation group (75.8%) compared with the subluxation group (27.7%; P < .001), whereas the prevalence of glenoid defects was not significantly different between groups (36.3% vs 29.2%, respectively; P = .393). The combined defect size was significantly larger in the dislocation versus subluxation group (mean ± SD combined defect score, 2.1 ± 1.6 vs 0.8 ± 0.9 points, respectively; P < .001) due to a larger Hill-Sachs lesion at dislocation than subluxation (glenoid defect score, 0.5 ± 0.9 vs 0.3 ± 0.6 points [P = .112]; Hill-Sachs lesion score, 1.6 ± 1.2 vs 0.4 ± 0.7 points [P < .001]). Combined defect size was larger in older patients than younger patients in the setting of dislocation (combined defect score, <20 years, 1.6 ± 1.2 points; 20-29 years, 1.9 ± 1.5 points; ≥30 years, 3.4 ± 1.6 points; P < .001) but was not different in the setting of subluxation (0.8 ± 1.0, 0.7 ± 0.9, and 0.8 ± 0.8 points, respectively; P = .885). An off-track Hill-Sachs lesion was observed in 2 older patients with dislocation but was not observed in shoulders with subluxation. Conclusion: The bipolar bone defect was significantly more frequent, and the combined size was greater in shoulders with primary dislocation and in older patients (≥30 years).

Abstract
BACKGROUND Many surgeons prefer bony stabilization including Bristow or Latarjet procedures for shoulder instability in collision athletes, even though several potential complications have been reported. There has been a limited number of studies on the midterm outcomes of arthroscopic soft tissue stabilization for anterior shoulder instability in competitive collision athletes. PURPOSE To assess the outcomes of arthroscopic soft tissue stabilization in combination with selective augmentation procedures for collision athletes with traumatic anterior shoulder instability. STUDY DESIGN Case series; Level of evidence, 4. METHODS We retrospectively assessed rugby or American football players (<40 years old) who underwent arthroscopic Bankart or bony Bankart repair with selective augmentations (rotator interval closure and/or Hill-Sachs remplissage) for traumatic anterior shoulder instability between January 2012 and March 2017. Shoulders that required other bony procedures were excluded. Recurrence, complications, return to sport, and functional scores (Rowe score and Subjective Shoulder Value sports score) were investigated. RESULTS This study included 113 shoulders in 100 patients with a mean age of 20 years (range, 15-36 years) at surgery. Rotator interval closure was performed on 36 shoulders in addition to Bankart repair, and rotator interval closure and Hill-Sachs remplissage were performed on 77 shoulders. The mean follow-up period was 44 months (range, 24-72 months). Of the 113 shoulders, 4 (3.5%) experienced postoperative dislocation, but there were no complications. A total of 93 athletes (93%) attained complete or near complete preinjury sports activity levels. The mean Rowe score significantly improved from 36 (range, 10-75) at presurgery to 96 (range, 35-100; P = .003) at postsurgery. The mean Subjective Shoulder Value sports score significantly improved after surgery, from a mean preoperative score of 22 (range, 0-50) to a postoperative score of 92 (range, 64-100; P = .002). CONCLUSION Our treatment strategy, where arthroscopic soft tissue stabilization was combined with selected augmentations, provided good clinical outcomes for competitive collision athletes in terms of low rates of recurrence and complication, a high rate of return to sports, and good shoulder function.

Abstract
BACKGROUND Diagnosis and treatment of traumatic posterior instability of the shoulder have not been described in detail. The author investigated surgical outcomes for traumatic posterior shoulder joint instability in collision athletes. METHODS The author surgically treated patients with a diagnosis of traumatic shoulder joint instability and investigated those that had been followed up for >2 years after surgery. RESULTS Seven shoulders in six collision athletes with a history of traumatic injury were examined. All cases were negative for the general laxity sign and positive for the posterior jerk test; five shoulders showed positive anterior apprehension. Posterior glenoid osseous defects were found in three shoulders, and one shoulder injury involved anterior and posterior osseous lesions. As surgical treatment, one posterior capsulolabral lesion, two posterior osseous lesions, and three combined anterior and posterior capsulolabral lesions were repaired arthroscopically. In a patient with a combined anterior and posterior osseous lesion, the Bristow procedure was perfromed after arthroscopic osseous repair. Patients returned to competition at an average of 6.8 months after surgery. One patient developed anterior subluxation at 7 months, and another exhibited posterior re-dislocation at 8 months after returning to competition. CONCLUSION Traumatic posterior instability in collision athletes often involves glenoid osseous lesions and is frequently accompanied by anterior apprehension and lesions. Although collision athletes can return to play after arthroscopic repair, such activity is associated with a risk of re-dislocation.

Abstract
INTRODUCTION The aim of this study is to estimate the annual number of shoulder dislocation hospitalizations in Italy from 2001 to 2014, to explore geographical variation in access to hospitalizations between the 3 macro-regions of Italy (North, Centre and South) and to perform statistical projections of hospitalizations volumes and rates based on data from 2001 to 2014. MATERIALS AND METHODS Data of the Italian Ministry of Health regarding the National Hospital Discharge records (SDO) were analysed for the period of the survey (2001-2014). These data are anonymous and include the patient's age, sex, domicile, region of hospitalization, length of the hospitalization, and type of reimbursement (public or private). RESULTS During the 14-year study period, 92,784 hospitalizations to treat shoulder dislocation were performed in Italy, which represented an incidence of 11.2 hospitalizations for every 100,000 Italian inhabitants. 56,514 patients underwent hospitalization for non-surgical treatment. 36,270 patients underwent hospitalization for surgical treatment. The higher hospitalizations rate was among males from 15 to 64 years of age. CONCLUSIONS Increasing rates of surgical hospitalization and decreasing rates of hospitalization for non-surgical treatment of shoulder dislocation are observed over a 14-year period. This study confirms that the socioeconomic burden of shoulder dislocation surgery heavily affects the working population. Most shoulder instability procedures were performed on males. The present study provides a description of the frequency and national distribution of shoulder instability in Italy. This study shows an increase in surgical procedures for shoulder instability in Italy.

Abstract
BACKGROUND The optimal surgical approach for recurrent anterior shoulder instability remains controversial, particularly in the face of glenoid and/or humeral bone loss. The purpose of this study was to use a contingent-behavior questionnaire (CBQ) to determine which factors drive surgeons to perform bony procedures over soft tissue procedures to address recurrent anterior shoulder instability. METHODS A CBQ survey presented each respondent with 32 clinical vignettes of recurrent shoulder instability that contained 8 patient factors. The factors included (1) age, (2) sex, (3) hand dominance, (4) number of previous dislocations, (5) activity level, (6) generalized laxity, (7) glenoid bone loss, and (8) glenoid track. The survey was distributed to fellowship-trained surgeons in shoulder/elbow or sports medicine. Respondents were asked to recommend either a soft tissue or bone-based procedure, then specifically recommend a type of procedure. Responses were analyzed using a multinomial-logit regression model that quantified the relative importance of the patient characteristics in choosing bony procedures. RESULTS Seventy orthopedic surgeons completed the survey, 33 were shoulder/elbow fellowship trained and 37 were sports medicine fellowship trained; 52% were in clinical practice ≥10 years and 48% <10 years; and 95% reported that the shoulder surgery made up at least 25% of their practice. There were 53% from private practice, 33% from academic medicine, and 14% in government settings. Amount of glenoid bone loss was the single most important factor driving surgeons to perform bony procedures over soft tissue procedures, followed by the patient age (19-25 years) and the patient activity level. The number of prior dislocations and glenoid track status did not have a strong influence on respondents' decision making. Twenty-one percent glenoid bone loss was the threshold of bone loss that influenced decision toward a bony procedure. If surgeons performed 10 or more open procedures per year, they were more likely to perform a bony procedure. CONCLUSION The factors that drove surgeons to choose bony procedures were the amount of glenoid bone loss with the threshold at 21%, patient age, and their activity demands. Surprisingly, glenoid track status and the number of previous dislocations did not strongly influence surgical treatment decisions. Ten open shoulder procedures a year seems to provide a level of comfort to recommend bony treatment for shoulder instability.

Abstract
Purpose To determine whether differences in return-to-play (RTP) rate and performance-based outcomes exist following shoulder arthroscopy in athletes from the National Football League (NFL), National Basketball League (NBA), Major League Baseball (MLB), and National Hockey League (NHL). Methods Professional athletes from the NFL, NBA, MLB, and NHL who underwent shoulder arthroscopy between January 1998 and December 2016 were identified through an established review of injury reports and public archives. Sport-specific statistics were collected before and after shoulder arthroscopy for each athlete, providing a performance score. RTP was defined as the first game played postsurgery. Results Of the 208 professional athletes who met the inclusion criteria, 167 (80.3%) returned to play following shoulder arthroscopy, with MLB players returning at a significantly lower rate than those of other sports (P < .0001). NBA players had significantly shorter recovery times (201 days; P < .01) and MLB players had significantly longer recovery times (413 days; P < .001) when compared with athletes in other sports. The mean number of seasons played after shoulder arthroscopy was 3.7, 4.7, 4.8, and 5.8 for MLB, NFL, NHL, and NBA, respectively. NBA players performed worse in their first season postoperative compared with their preoperative performance (P = .0017), but their postoperative season 2 performance returned to their preoperative performance level (P = .1893). Similarly, NHL players performed worse in their postoperative season 1 compared with preoperative performance (P = .0274), but their postoperative season 2 performance improved upon their preinjury performance level (P = .0861). Conclusions There is a modest RTP rate among professional athletes following shoulder arthroscopy. MLB players have the longest average time to RTP and the shortest postinjury careers following shoulder arthroscopy. However, they demonstrate no significant decline in performance following their injury. Conversely, NBA players had the shortest average time to RTP and the longest post-injury career. Both NBA and NHL athletes experienced a decrease in performance in post-operative season one. Level of Evidence Level III, retrospective comparative study.

Abstract
BACKGROUND There are various modifications of the Bankart repair, and postoperative changes to the glenoid morphology after the repair are reported. Among the various procedures performed, a decrease in the lateral glenoid diameter might be related to the surgery that involves removal of the articular cartilage and repair of the labrum-anterior inferior glenohumeral ligament complex on the glenoid surface. This is in contrast to cases without significant bony Bankart lesions that are not on the edge of the glenoid. Thus, this study aimed to compare glenoid rim stress after Bankart repair using 2 methods of finite element analysis: a method of removing the anteroinferior cartilage and repairing the glenohumeral ligament complex on the glenoid and a method of preserving the cartilage and repairing the glenohumeral ligament complex on the glenoid edge. METHODS Five preoperative computed tomography scans of patients with traumatic anterior instability who underwent arthroscopic Bankart repair were used. Two models simulating different surgical procedures were created as follows: in model G, a 5-mm-thick cartilage on the glenoid rim was removed between 2 and 7 o'clock, and the glenohumeral ligament complex was repaired on the medial edge of the glenoid bone where the cartilage was removed. In model E, the cartilage on the glenoid rim was not removed, and the glenohumeral ligament complex was repaired on the glenoid edge. The load stresses on the anteroinferior area of the glenoid after Bankart repair with models G and E were measured using finite element analysis. RESULTS The stress on the glenoid at 3-4 o'clock was 3.16 MPa in model G and 6.42 MPa in model E (P = .043). The stress at 4-5 o'clock was 1.68 MPa in model G and 4.53 MPa in model E (P = .043). The stress at 5-6 o'clock was 2.26 MPa in model G and 3.93 MPa in model E (P = .043). CONCLUSION Significantly lower load stresses were observed at the anteroinferior rim of the glenoid in model G than in model E.

Abstract
The optimal management of anterior shoulder instability continues to be a challenge. The presence of an anterior glenoid rim fracture in the context of a glenohumeral dislocation, also called "bony Bankart lesion," can alter therapeutic behavior. Reduction and fixation of the bone fragment has been shown to greatly reduce the risk of recurrence once bone consolidation is achieved. However, there is no gold standard surgical technique. Stability of fixation and the healing of the bony fragment are still a concern, and there are no clinical studies comparing the different techniques to date. The aim of this report is to describe an arthroscopic double-point fragment fixation technique in lateral decubitus for the treatment of an acute traumatic shoulder dislocation with a bony Bankart lesion.

The Role of Remplissage in the Setting of Shoulder Instability. Sports Med Arthrosc Rev 2020; 28:140-145.

Abstract
Recurrent anterior shoulder instability is a multifactorial problem for which many solutions exist. Often, the bony surface area of the humeral head and the glenoid needs to be addressed surgically. For large, engaging humeral head defects associated with <25% glenoid bone loss, a remplissage procedure can effectively "fill in" the humeral defect with minimal postoperative morbidity. Remplissage is an effective biological solution that should be considered any time there is a humeral head defect which is contributing to glenohumeral instability.

Abstract
Introduction Fragment-type glenoid bone loss is known to remodel after arthroscopic Bankart repair. To our knowledge, no studies have been reported about the morphologic changes of the erosion-type bone loss. Aim To determine the morphologic changes of erosion-type glenoid bone loss after arthroscopic Bankart repair. Methods Twenty-eight patients (mean age: 31 years) with traumatic anterior glenohumeral instability with an erosion-type glenoid bone loss <25% underwent arthroscopic Bankart repair. The minimum follow-up was 2 years. Pre- and postoperative bilateral computed tomography scans were performed in all patients. The width and surface area of the glenoid were measured by a software program and compared pre- and postoperatively. Results The recurrence rate was 7.1% (2 of 28 shoulders). The size of the bone loss was 7.2% ± 5.3% (mean ± standard deviation). The preoperative glenoid width and area were 24.9 ± 2.2 mm and 7.0 ± 0.8 cm2, respectively, and the postoperative ones (2 years after surgery) were 24.7 ± 2.2 mm and 6.8 ± 0.8 cm2, respectively. There were no significant differences between the pre- and postoperative glenoid width and area. Discussion and conclusion Unlike the fragment-type bone loss, the erosion-type bone loss <25% did not show any morphologic changes of the glenoid at least 2 years after arthroscopic Bankart repair.

Abstract
Healthy shoulder function requires the coordination of the rotator cuff muscles to maintain the humeral head's position in the glenoid. While glenohumeral stability has been studied in various settings, few studies have characterized the effect of dynamic rotator cuff muscle loading on glenohumeral translation during shoulder motion. We hypothesize that dynamic rotator cuff muscle activation decreases joint translation during continuous passive abduction of the humerus in a cadaveric model of scapular plane glenohumeral abduction. The effect of different rotator cuff muscle activity on glenohumeral translation was assessed using a validated shoulder testing system. The Dynamic Load profile is a novel approach, based on musculoskeletal modeling of human subject motion. Passive humeral elevation in the scapular plane was applied via the testing system arm, while the rotator cuff muscles were activated according to the specified force profiles using stepper motors and a proportional control feedback loop. Glenohumeral translation was defined according to the International Society of Biomechanics. The Dynamic load profile minimized superior translation of the humeral head relative to the conventional loading profiles. The total magnitude of translation was not significantly different (0.805) among the loading profiles suggesting that the compressive forces from the rotator cuff primarily alter the direction of humeral head translation, not the magnitude. Rotator cuff muscle loading is an important element of cadaveric shoulder studies that must be considered to accurately simulate glenohumeral motion. A rotator cuff muscle activity profile based on human subject muscle activity reduces superior glenohumeral translation when compared to previous RC loading profiles.

Arthroscopic stabilisation for shoulder instability. J Clin Orthop Trauma 2020; 11:S402-S411.

Abstract
Since its first description over 30 years ago arthroscopic stabilisation has evolved. With improvements in knowledge, surgical techniques and materials technology, arthroscopic bankart repair has become the most widely used method for treating patients with symptomatic anterior shoulder instability. These procedures are typically performed in a younger, high demand patient population after a primary dislocation or to treat recurrent instability. A thorough clinical evaluation is required in the clinic setting not only to fully understand the injury pattern but also consider patient expectations prior to embarking on surgery. Diagnostic imaging will aid the clinician in determining the soft tissue pathology as well as assessing bone loss, which facilitates surgical decision-making. Selected patients may benefit from adjunctive procedures such as a remplissage for an "engaging" Hill-sachs lesion. This review will focus on the indications, pre-operative considerations, surgical techniques and outcomes of arthroscopic stabilisation.

Abstract
Limited knowledge is accessible concerning the tendencies of hospitalization for skeletally immature patients with episodes of shoulder dislocation. Our research aim was to evaluate annual hospitalizations for shoulder dislocation in paediatric patients in Italy from 2001 to 2014, on the basis of the official data source as hospitalization reports. The second purpose was to investigate geographical diversification in hospitalization for shoulder dislocation in regions of Italy. The last aim was to make statistical predictions of the number of shoulder dislocation hospitalization volumes and rates in skeletally immature patients based on data from 2001 to 2014. An examination of the National Hospital Discharge records (SDO) kept at the Italian Ministry of Health regarding the 14 years of our study (2001 through 2014) was conducted. These data are anonymous and include patient's age, gender, domicile, region and time of hospitalization, and the kind of reimbursement (public or private). In the 14-year study time, 344 hospitalizations for shoulder dislocation of patients aged 0-14 years took place in Italy. The male/female hospitalization ratio varied from a maximum of 3.0 (2001) to a minimum of 1.1 (2013), with a mean average ratio in the 2001-2014 timespan of 2.0. Almost half of the hospitalizations (49.1%) were performed in the South. The mean incidence of hospitalizations in Italy for shoulder dislocation in patients with less than 14 years was 0.3 for every 100,000 inhabitants in the same class of age. The most common treatment was a closed reduction (60.8%), followed by open stabilization (16.6%) and arthroscopic procedures (13.7%). The present registry study shows a low incidence of hospitalization for shoulder dislocation in young patients. The most common treatment for a shoulder dislocation in paediatric patients is a closed shoulder reduction. Regions from the south and the centre of Italy are marked by an inferior number of operations and a higher number of hospitalization for closed shoulder reduction.

Abstract
PURPOSE To evaluate changes of the glenoid after arthroscopic Bankart repair (ABR) in patients with different preoperative glenoid structures. METHODS Patients who underwent ABR for traumatic anterior shoulder instability were retrospectively investigated. They were divided into 3 groups on the basis of preoperative glenoid structure by computed tomography (CT): normal glenoid (group N), glenoid erosion (group E), or glenoid defect associated with a bony Bankart lesion (group B). Shoulders in group B were also stratified according to the postoperative status of the bone fragment (union, nonunion, or resorbed). Postoperative changes of glenoid width (Δ) (increase: Δ ≥5%, stable: Δ >-5% to <5%, decrease: Δ ≤-5%) and the extent of glenoid bone loss were investigated by 3-dimensional CT. RESULTS A total of 186 shoulders were divided into 3 groups: group N (n = 61), group E (n = 46), and group B (n = 79). At initial postoperative CT, the glenoid width was decreased in 41 shoulders, stable in 20 shoulders, and increased in no shoulders from group N. The respective numbers were 27, 18, and 1 in group E, and 50, 22, and 7 in group B. The glenoid width was reduced in all groups (mean percent change: -8.8%, -5.9%, and -6.1%, respectively). In group B, glenoid width decreased in most of the shoulders without bone union. The glenoid bone loss on the preoperative and postoperative final CT was, respectively, 0% and 8.6% in group N (P < .0001), 9.9% and 12.4% in group E (P = .03), and 10.4% and 7.2% in group B (P = .01). Final glenoid bone loss >13.5% was recognized in 18.2% of group N, 35.7% of group E, and 21.8% of group B. CONCLUSIONS Glenoid width often decreased after ABR because of anterior glenoid rim erosion, and this change was frequent in patients with preoperative normal glenoid, glenoid erosion, or without postoperative union of a bony Bankart lesion.

Abstract
BACKGROUND It has been biomechanically demonstrated that 20% to 25% is a critical glenoid bone loss. Recently, there are several reports describing that a bone loss less than 20% to 25% needed to be treated because patients may have decreased quality of life without recurrent instability events. The purpose of this study was to clarify the presence of subcritical bone loss that would affect postoperative instability or quality of life. METHODS Subjects were 43 patients aged≤40years with less than 25% glenoid bone loss who had undergone arthroscopic Bankart repair. These patients were assessed at a mean follow-up of 32months. The Western Ontario Shoulder Instability (WOSI) and Rowe scores were used for the clinical evaluation. Patients were divided in 3 groups based on the percentage of bone loss: group 1: <8%; group 2: 8% to 17%; and group 3: >17%. RESULTS The recurrence rate was 7% (3/43 shoulders). A weak negative correlation was seen between bone loss and sports/recreation/work domain of the WOSI score (r=-0.304, p=0.0191). The WOSI for group 3 was significantly lower than that for group 1 and 2 (p=0.0009). The male WOSI scores were significantly lower than the female ones (p=0.0471). The WOSI scores of the contact athletes were significantly lower than those of non-contact athletes (p=0.0275). All the patients in Group 3 were males and participated in contact sports. CONCLUSION Glenoid bone loss between 17% and 25% is considered to be a "subcritical bone loss" in our series, especially in male patients who are involved in sports or high-level activities. LEVEL OF EVIDENCE III, retrospective study.

Abstract
Background The combination of a glenoid defect and a Hill-Sachs lesion in shoulders with traumatic anterior instability has been termed bipolar bone loss, and the preoperative size of these lesions has been reported to influence postoperative recurrence of instability after arthroscopic Bankart repair. Purpose To investigate the influence of postoperative bipolar bone defect size on postoperative recurrence of instability. Study Design Cohort study; Level of evidence, 3. Methods A total of 64 male collision/contact athletes (69 shoulders) were evaluated for a minimum of 2 years after surgery, and the pre- and postoperative sizes of both lesions (glenoid defect and Hill-Sachs) were evaluated retrospectively with 3-dimensional computed tomography. The sports played by the athletes included rugby (n = 28 shoulders), American football (n = 24 shoulders), and other collision/contact sports (n = 17 shoulders). Glenoid defects and Hill-Sachs lesions were classified into 5 size categories and assigned scores from 0 (no defect) to 4 (very large defect). Patients were then classified according to the total score (sum of the scores for both lesions). The influence of pre- and postoperative bipolar bone defect sizes on recurrence of instability was investigated by using the total scores for bipolar bone defects. The influence of postoperative glenoid morphology (normal preoperative glenoid, preoperative glenoid erosion, bone union after arthroscopic bony Bankart repair [ABBR], or nonunion after ABBR) was also investigated, as well as changes in shoulders with a preoperative off-track Hill-Sachs lesion. Results Of 69 shoulders, 15 (21.7%) developed recurrent instability after surgery. The postoperative recurrence rate was 0% in shoulders with a total score ≤1, while the recurrence rate was consistently higher in shoulders with a total score ≥2 at both pre- and postoperative evaluation (mean, 28.8% and 32.6%, respectively). Postoperative recurrence was uncommon when there was a normal preoperative glenoid or bone union after ABBR, while it was frequent in shoulders with preoperative glenoid erosion or shoulders with nonunion after ABBR and a total score ≥2. An off-track lesion was recognized in 9 shoulders preoperatively. It was transformed to on-track lesions in 4 of the 5 shoulders showing bone union after ABBR, and there was no recurrence in the 5 shoulders with bone union. In contrast, postoperative recurrence of instability occurred in 3 of the 4 shoulders without bone union. Conclusion Postoperative recurrence was influenced by the pre- and postoperative size of bipolar bone defects. Recurrence was uncommon if bone union was achieved after ABBR, even if there had been an off-track lesion preoperatively.

Abstract
BACKGROUND The surgical treatment of recurrent shoulder instability has evolved in recent years to include a variety of soft tissue and bone block procedures, undertaken with either an open or arthroscopic approach. Although the utilization of such techniques has rapidly expanded, the associated risk of complications remains poorly defined. This information is vital for clinical decision making and patient counseling. PURPOSE To quantify the complication rate associated with all types of surgery for anterior glenohumeral joint dislocation. STUDY DESIGN Systematic review. METHODS A systematic search was undertaken of studies reporting complications from anterior shoulder stabilization surgery. Inclusion criteria were studies published in English between 2000 and 2017 with a minimum 2-year follow-up. Methodological quality of the included studies was assessed with the Methodological Index for Non-Randomized Studies criteria. Complication rates for all undesirable events contributing to the patient outcome were extracted and cumulative rates calculated. RESULTS Out of 1942 references, 56 studies were included, totaling 4362 procedures among 4336 patients. Arthroscopic soft tissue repair had a complication rate of 1.6% (n = 2805). When repair was combined with arthroscopic remplissage, the rate was 0.5% (n = 219). Open soft tissue repair had a complication rate of 6.2% (n = 219) and open labral repair with remplissage, a rate of 2.3% (n = 79). An open bone block procedure had a complication rate of 7.2% (n = 573) and an arthroscopic bone block procedure, a rate of 13.6% (n = 163). CONCLUSION This large systematic review demonstrates the overall complication rates (not purely recurrence rates) in modern shoulder stabilization surgery. With the growing interest in bone block stabilization procedures, including those performed arthroscopically, surgeons should be aware of the 10-fold increase in complications for these procedures over soft tissue arthroscopic surgery and counsel their patients accordingly.

Abstract
BACKGROUND There is increasing evidence to suggest that the amount of glenoid bone loss to indicate bone block procedures may be lower than previously thought, particularly in the presence of a Hill-Sachs defect. PURPOSE To better establish treatment recommendations for anterior shoulder instability among patients with bipolar bone lesions. STUDY DESIGN Systematic review and meta-analysis; Level of evidence, 4. METHODS A systematic review of the literature was performed with PubMed, EMBASE, Cochrane Library, and Scopus databases according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines. Studies evaluating outcomes of operative management in anterior shoulder instability that also reported glenoid bone loss in the presence of Hill-Sachs defects were included. Recurrence rates, glenoid bone loss, and humeral bone loss were pooled and analyzed with forest plots stratified by surgical procedure. Methods of quantification were analyzed for each article qualitatively. RESULTS Thirteen articles were included in the final analysis, with a total of 778 patients. The mean ± SD age was 24.9 ± 8.6 years. The mean follow-up was 30.1 months (range, 11-240 months). Only 13 of 408 (3.2%) reviewed bipolar bone loss articles quantified humeral and/or glenoid bone loss. Latarjet procedures had the greatest glenoid bone loss (21.7%; 95% CI, 14.8%-28.6%), followed by Bankart repairs (13.1%; 95% CI, 9.0%-17.2%), and remplissage (11.7%; 95% CI, 5.5%-18.0%). Humeral bone loss was primarily reported as percentage bone loss (22.2%; 95% CI, 13.1%-31.3% in Bankart repairs and 31.7%; 95% CI, 21.6%-41.1% in Latarjet) or as volumetric defects (439.1 mm3; 95% CI, 336.3-541.9 mm3 in Bankart repairs and 366.0 mm3; 95% CI, 258.4-475.4 mm3 in remplissage). Recurrence rates were as follows: Bankart repairs, 19.5% (95% CI, 14.5%-25.8%); remplissage, 4.4% (95% CI, 1.3%-14.0%); and Latarjet, 8.7% (95% CI, 5.0%-14.7%). Bankart repairs were associated with significantly greater recurrence of instability in included articles (P = .013). CONCLUSION There exists a need for universal and consistent preoperative measurement of humeral-sided bone loss. The presence of concomitant Hill-Sachs defects with glenoid pathology should warrant more aggressive operative management through use of bone block procedures. Previously established values of critical glenoid bone loss are not equally relevant in the presence of bipolar bone loss.

Abstract
Background Partial articular supraspinatus tendon avulsion (PASTA) lesions are often seen in shoulders of throwing athletes. PASTA lesions in anterior instability are also found in recurrent anterior glenohumeral instability. Purpose To investigate the prevalence and location of rotator cuff tears (RCTs), including PASTA lesions, in shoulders with recurrent anterior instability. Study Design Case series; Level of evidence, 4. Methods A total of 842 shoulders in 801 patients with recurrent anterior instability (647 men, 154 women; mean age, 24 years; age range, 13-40 years) who underwent arthroscopic surgery at the age of 40 years or younger were enrolled. During surgery, the thickness and the sites of RCTs as well as patient factors associated with RCTs were examined. Results RCTs were found in 57 shoulders (7%) in 56 patients. There were 4 shoulders with full-thickness RCTs and 54 shoulders with PASTA lesions. All lesions but 1 involved the anterior border of the supraspinatus (SSP). Participation in high-level athletics and older age at injury were associated with RCTs. Conclusion The incidence of RCTs was 7% in shoulders with recurrent anterior instability at age 40 years or younger. Most RCTs were PASTA lesions that involved the anterior border of the SSP.
