Arthroscopic Bankart Repair for Anterior Glenohumeral Instability in 488 Adolescents Between 2000 and 2020: Risk Factors for Subsequent Recurrent Instability Requiring Revision Stabilization. Am J Sports Med 2024; 52:2331-2339. [PMID: 39101737 PMCID: PMC11308280 DOI: 10.1177/03635465241259736] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/05/2023] [Accepted: 04/16/2024] [Indexed: 08/06/2024]
Abstract
BACKGROUND After arthroscopic Bankart repair (ABR) for anterior glenohumeral instability (GHI), adolescent athletes have higher rates of subsequent recurrent GHI than any other subpopulation. Elucidating which adolescents are at highest risk of postoperative recurrent GHI may optimize surgical decision-making. PURPOSE To identify prognostic factors associated with subsequent recurrent GHI requiring revision stabilization surgery (RSS) after ABR. STUDY DESIGN Case-control study; Level of evidence, 3. METHODS The study included patients 12 to 21 years old who had undergone ABR for anterior GHI at a pediatric tertiary care hospital by 1 of 5 sports medicine fellowship-trained surgeons between 2000 and 2020. A multivariate Cox proportional hazards model, with percentage of patients with recurrent GHI undergoing subsequent RSS, was used with a time-to-event outcome analysis. The Cox model effects were expressed as the hazard ratio (HR). All tests were 2-sided, with an alpha of .05. RESULTS Records of 488 adolescent patients with ABR (78% male; mean age, 16.9 ± 1.98 years) were analyzed. Of these, 86 patients (17.6%) underwent subsequent RSS for recurrent GHI, yielding a cumulative risk of 8.8% at 2 years, 16.5% at 5 years, and 20% at 15 years. RSS occurred at a mean of 2.6 ± 2.1 years after ABR. Risk factors for RSS included >1 preoperative dislocation (2 dislocations: HR = 7.4, P = .0003; ≥3 dislocations: HR = 10.9, P < .0001), presence of a Hill-Sachs lesion (small: HR = 2.5, P = .0114; medium-large: HR = 4.2, P = .0004), younger age (1-year decrease: HR = 1.2, P = .0015), and participation in contact sports (HR = 1.8, P = .01). Adolescents with only 1 preoperative dislocation had a cumulative incidence of RSS (3.2%), which was significantly lower than those with 2 (24.2%) or ≥3 preoperative dislocations (33.5%). CONCLUSION The number of dislocations before index ABR was the strongest risk factor for recurrent GHI requiring RSS in adolescents with anterior GHI, with 2 dislocations conferring >7-fold increased risk compared with a single preoperative dislocation. Other significant risk factors included the presence of a Hill-Sachs lesion, younger age, and participation in contact sports.

Zhang C, Yang S, Pang L, Li T, Li Y, Wang H, Huang Y, Tang X. Salvage Latarjet may provide worse outcomes in terms of recurrent instability and returning to sports compared to primary Latarjet: a systematic review of comparative studies. BMC Musculoskelet Disord 2024; 25:500. [PMID: 38937741 PMCID: PMC11212418 DOI: 10.1186/s12891-024-07593-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/26/2024] [Accepted: 06/12/2024] [Indexed: 06/29/2024] Open
Abstract
BACKGROUND The Latarjet procedure (LP) is performed as a primary stabilization procedure (primary LP) and a salvage procedure when an earlier shoulder stabilization procedure has failed (salvage LP). However, whether primary LP or salvage LP provides better outcomes for anterior shoulder instability remains unknown. METHODS Two independent reviewers performed the literature search based on the PRISMA guidelines. A comprehensive search of PubMed, Embase, web of science and Cochrane Library was performed from their inception date to December 4, 2023. Inclusion criteria mainly included the comparison of postoperative outcomes between primary and salvage LP, English language, and full text availability. Two reviewers independently examined the literature, collected data, and evaluated the methodological robustness of the included studies. The Methodological Index for Nonrandomized Studies was used to evaluate the quality of nonrandomized studies. Recurrent instability, complications, reoperations, return to sports, patient-reported outcomes, and range of motion were assessed. Statistical evaluations were conducted using Manager V.5.4.1 (The Cochrane Collaboration, Software Update, Oxford, UK). RESULTS Twelve studies were included in the systematic review, with 940 shoulders undergoing primary LP and 631 shoulders undergoing salvage LP. Statistically significant differences in favor of primary LP were found in 2 of the 11 and 2 of 4 included studies in terms of recurrent instability and returning to the same sports (RTS) at preinjury level, respectively. In terms of the visual analog scale, subjective shoulder value and the Western Ontario Shoulder Instability Index, 2 of the 4, 1 of the 3 and 1 of the 3 included studies reported statistically significant differences in favor of primary LP. Differences were not noticed regarding complications, reoperations, the time to RTS, the Rowe score, the Athletic Shoulder Outcome Scoring System, and forward flexion. CONCLUSION Current evidence suggests that compared with primary LP, salvage LP may provide inferior postoperative outcomes in terms of recurrent instability and the rate of RTS at preinjury level. Primary and salvage LP may yield comparable efficacy in terms of complications, reoperations, the rate of RTS, the time to RTS, pain, shoulder function, and range of motion.

Abstract
BACKGROUND Given the variability across populations and settings, defining the MCID and the PASS for the Rowe and ASOSS scores and patients undergoing primary and revision Latarjet it is essential to have accurate benchmarks relevant to these groups when interpreting clinical results. PURPOSE To determine the minimal clinically important difference (MCID) and Patient Acceptable Symptom State (PASS) thresholds for the visual analog scale (VAS) for pain during sports, Athletic Shoulder Outcome Scoring System (ASOSS), and Rowe scores after primary and revision Latarjet procedures for treatment of shoulder instability. STUDY DESIGN Cohort study (diagnosis); Level of evidence, 3. METHODS Between January 2018 and January 2020, a retrospective review of 149 patients undergoing primary Latarjet (n = 82) and revision Latarjet (n = 67) to treat shoulder instability was performed in a single institution. Patient-reported outcome measures were collected preoperatively and 1 year postoperatively. The delta was defined as the change between the pre- and postoperative scores. Distribution-based and anchored-based approaches were used to estimate the MCID and the PASS, respectively. The optimal cutoff point and the percentage of patients achieving those thresholds were also calculated. RESULTS The distribution-based MCIDs after primary Latarjet were 1.1, 7.5, and 9.6 for the VAS, Rowe, and ASOSS scores, respectively. The rates of patients who achieved the MCID thresholds were 93.9%, 98.7%, and 100% for the VAS, Rowe, and ASOSS scores, respectively. The PASS thresholds after primary Latarjet were ≤1, ≥90, and ≥85 for the VAS, Rowe, and ASOSS scores, respectively. The percentages of patients who achieved PASS thresholds were 82.9%, 89%, and 86.5% for the VAS, Rowe, and ASOSS scores, respectively. The distribution-based MCIDs after revision Latarjet were 0.6, 6.2, and 3.4 for the VAS, Rowe, and ASOSS scores, respectively. The rates of patients who achieved MCID thresholds were 89.3%, 100%, and 100% for the VAS, Rowe, and ASOSS scores, respectively. The PASS thresholds were ≤3, ≥87, and ≥86 after revision Latarjet for the VAS, Rowe, and ASOSS scores, respectively. The rates of patients who achieved the PASS thresholds were 88%, 88%, and 91% for the VAS, Rowe, and ASOSS, respectively. CONCLUSION This study identified useful values for the MCID and PASS thresholds in VAS, Rowe, and ASOSS scores after primary and revision Latarjet procedures for treating shoulder instability. Most patients achieved MCID and PASS benchmarks, indicating successful primary and revision Latarjet procedure outcomes. These metrics can serve as valuable parameters when analyzing parameters in future studies and have the potential to enhance patient care by optimizing treatment strategies and surgical decision making.

Abstract
Background To systematically review the literature to evaluate the outcomes following an open Latarjet (OL) procedure at a minimum 15-year follow-up. Methods Two independent reviewers performed a literature search using Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines using 3 databases. Only studies reporting outcomes of OL procedure with a minimum of 15 years of follow-up were included. Results Nine studies composed of 326 shoulders (78.2% males) in 313 patients were included (average age 26.9 ± 3.2 years (15-58)), with a mean follow-up of 271.9 ± 69.2 months (180-420) At a minimum 15-year follow-up, 93.5% (286 of 306) patients reported being satisfied with their OL procedure, whilst 86.8% (177 of 204) reported good/excellent outcomes at final follow-up. All nine of the included studies reported an overall rate of recurrent instability was 7.7%, with re-dislocations and subluxation at 3.4% and 5.8%, respectively. The rate of surgical revision was 5.15%; 3.5% of cases were revised for recurrent instability. Instability arthropathy was reported across all included studies as 41.0%. Conclusion The OL procedure results in satisfactory clinical outcomes, low rates of recurrent instability and surgical revision at a minimum 15-year follow-up. Although high levels of radiological instability arthropathy and residual pain are found over the same period, these appear stable from a minimum of 10-year follow-up data. Level of Evidence IV; a systematic review of all levels of evidence.

Abstract
OBJECTIVES The purpose of this study is to systematically review the comparative studies in the literature to compare the outcomes of the Latarjet procedure in the setting of a previously failed Bankart repair versus those undergoing the Latarjet procedure as a primary surgery for anterior shoulder instability. METHODS A systematic search in Pubmed, EMBASE, and The Cochrane Library databases was carried out according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. Cohort studies comparing outcomes in the Latarjet procedure as a primary surgery versus the Latarjet procedure in the setting of a previously failed Bankart repair were included. RESULTS Ten studies with 1913 patients were included. There was a significantly lower rate of recurrent instability in those with a Latarjet procedure as a primary surgery (4.8% vs 12.1%, p = 0.007). There was also a significantly lower rate of complications with the Latarjet procedure as a primary surgery (6.2% vs 10.2%, p = 0.03). Furthermore, there was a significant difference in the rate of revision surgery in favour of the Latarjet procedure as a primary surgery (4.8% vs 10.9%, p = 0.02). However, there were similar rates of redislocations (2.8% vs 3.4%, p = 0.82) and return to play (67.7% vs 78.5%, p = 0.30) between the two cohorts. CONCLUSION This study found that the Latarjet procedure as a revision procedure for a previously failed Bankart repair resulted in higher rates of complications, recurrent instability, and revisions than the Latarjet procedure performed as a primary procedure. LEVEL OF EVIDENCE Level III, Systematic Review & Meta-Analysis of Level III studies.

The clinical utility of immediate post-operative PACU plain film radiographs following uncomplicated open Latarjet procedure - An institutional series of consecutive patients. J Orthop 2023; 46:178-181. [PMID: 38037554 PMCID: PMC10685133 DOI: 10.1016/j.jor.2023.11.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/20/2023] [Accepted: 11/03/2023] [Indexed: 12/02/2023] Open
Abstract
Background Immediate post-operative plain film radiograph x-rays in PACU following open Latarjet procedure are often ordered as routine. However, such radiographs utilize institutional cost and time, whilst potentially exposing patients to often-unnecessary additional radiation. This study sought to evaluate whether routine immediate post-operative radiographs following uncomplicated open Latarjet procedures impacted clinical decision-making in our institution. Methods From 2017 to 2020, patients who underwent open Latarjet procedure by one of four fellowship-trained upper limb surgeons at a single institution were included in this study. Post-operative radiographs taken immediately in PACU were reviewed to determine if any reported radiographic findings impacted on clinical decision-making in the immediate post-operative setting. SPSS was used for descriptive statistics. Results A total of 337 patients underwent an X-ray in PACU immediate after uncomplicated open Latarjet procedure. Overall, 98.5% were male (n = 332), the mean patient age of included patients was 22.9 ± 4.2 years. No patient had an abnormal finding on their post-operative x-ray. Two patients returned to the operating room in the immediate post-operative period, both requiring washout and debridement due to haemtoma or superficial wound infection. Conclusion The findings of this study suggest that the use of post-operative plain films in PACU following open Latarjet procedure remains a costly use of resources, with little ultimate impact on clinical decision making in the short-term post-operatively.

J Shoulder Elbow Surg 2023; 32:2599-2612. [PMID: 37541335 DOI: 10.1016/j.jse.2023.07.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/26/2023] [Revised: 06/27/2023] [Accepted: 07/02/2023] [Indexed: 08/06/2023]
Abstract
BACKGROUND Latarjet has become an increasingly popular treatment option for recurrent anterior shoulder instability. With the reported complication rates for primary Latarjet surgery, there are concerns about the complications of Latarjet as a revision surgery. It remains unclear if poor results after previous surgical management can be improved with revision Latarjet as well as with primary Latarjet. The aim of this systematic review and meta-analysis is to compare the outcomes of primary Latarjet and revision Latarjet for the treatment of anterior shoulder instability. METHODS A systematic search was performed on 3 databases for studies that compared primary Latarjet with revision Latarjet used after failed arthroscopic stabilization or failed free bone block procedures. From the included studies, demographic data, clinical outcome scores, range of motion measurements, and postoperative complications were obtained. RESULTS A total of 11 studies were included for data analysis. Compared with the primary Latarjet cohort, revision Latarjet cohorts had a higher infection rate (1.2% vs. 2.6%; RR 0.46, P = .039). The primary Latarjet group showed a greater rate of return to sport (89.7% vs. 80.5%; RR 1.12, P = .41) and less subjective feeling of instability (12.6% vs. 20.9%; RR 0.60, P = .085) compared with the revision Latarjet group; however, this was not statistically significant. There were no significant differences in complication rates, reoperation, recurrence, and range of motion between primary Latarjet and revision Latarjet groups. Clinical outcome scores such as visual analog scale and Rowe scores were not significantly different between the cohorts. CONCLUSION Based on the current evidence, primary Latarjet presents reduced infection rates but similar clinical outcome measures, overall complication, and range of motion measurements than revision Latarjet performed after failed prior operative treatment.

Abstract
Background Currently, is there no consensus on a widely accepted measurement technique for calculating the Hill-Sachs lesion (HSL). The purpose of this review is to provide an overview of the techniques and imaging modalities to assess the HSL pre-operatively. Methods Four online databases (PubMed, Embase, MEDLINE, and COCHRANE) were searched for literature on the various modalities and measurement techniques used for quantifying HSLs, from data inception to 20 November 2021. The Methodological Index for Non-Randomized Studies tool was used to assess study quality. Results Forty-five studies encompassing 3413 patients were included in this review. MRA and MRI showed the highest sensitivity, specificity, and accuracy values. Intrarater and interrater agreement was shown to be the highest amongst MRA. The most common reference tests for measuring the HSL were arthroscopy, radiography, arthro-CT, and surgical techniques. Conclusion MRA and MRI are reliable imaging modalities with good test diagnostic properties for assessment of HSLs. There is a wide variety of measurement techniques and imaging modalities for HSL assessment, however a lack of comparative studies exists. Thus, it is not possible to comment on the superiority of one technique over another. Future studies comparing imaging modalities and measurement techniques are needed that incorporate a cost-benefit analysis.

Abstract
BackgroundDislocation of the shoulder joint is the most common type of joint dislocation. It is rare to be in a persistent dislocation that has not been reset. Successful arthroscopic treatment of the obsolete shoulder is relatively uncommon.Case reportWe report a rare case of persistent anterior dislocation of the old shoulder joint in a 30-year-old female patient. The patient underwent an emergency shoulder dislocation at a local hospital after a traumatic injury and re-dislocated persistently after surgery. 26 days later, she was admitted to our department for treatment, mainly because of joint deformity and limitation of motion. We adopted arthroscopic release and repositioning surgery. The patient was followed up for 1 year after surgery. Functional recovery was satisfactory.ConclusionThe state of obsolete shoulder dislocation rarely occurs after shoulder dislocation and the prognosis of the patient is good after complete arthroscopic release and repositioning. It provides a reference for clinical arthroscopic treatment of old shoulder dislocations.

Abstract
BACKGROUND The purpose of this study was to systematically review the literature to ascertain the clinical outcomes of the open Latarjet (OL) procedure using either a subscapularis-split (SS) or subscapularis tenotomy (ST) via a deltopectoral (DP) approach. METHODS Two independent reviewers performed a literature search using the PubMed, Embase, and Scopus databases according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines. Only studies reporting on outcomes of the OL procedure via a DP approach comparing both SS and ST were considered for inclusion. Meta-analysis to compare clinical outcomes was performed using RevMan software. RESULTS Our search found 5 studies that met our inclusion criteria, including 615 shoulders (80.8% male patients), with an average age of 27.8 ± 12.6 years (range, 15-79 years) and mean follow-up period of 50.1 ± 29.4 months (range, 12-180 months). A total of 410 shoulders and 205 shoulders underwent the OL procedure via a DP approach using the ST technique and the SS technique, respectively, with both techniques resulting in significant increases in the Rowe score postoperatively (P < .0001 for both). Additionally, significantly higher postoperative Constant scores were observed in patients who underwent the OL procedure via an SS technique vs. those in the ST group (91.8 ± 7.2 vs. 79.6 ± 16.1, P < .0001). However, meta-analysis showed nonsignificantly higher postoperative Rowe and American Shoulder and Elbow Surgeons scores in patients who underwent the OL procedure via an SS technique vs. those in the ST group (96.1 ± 2.6 vs. 86.4 ± 7.6 [P = .57] and 91.6 ± 1.3 vs. 80.6 ± 25.5 [P = .47], respectively). Furthermore, meta-analysis showed that significantly more patients in the ST group had positive lift-off test results (10.0%) when compared with the SS group at final follow-up (2.7%, P = .01). However, meta-analysis indicated that the rate of recurrent instability was trending toward significance in favor of the SS group (0% vs. 11.7%, P = .07). CONCLUSION Our systematic review established that in cases of OL procedures being carried out via a DP approach, the SS technique results in significantly better functional outcome measures and significantly lower rates of subscapularis insufficiency when compared with an L-shaped ST technique at medium-term follow-up. Furthermore, there were lower rates of recurrent instability that were trending toward significance in favor of the SS technique.

Abstract
Anterior shoulder instability is a common orthopaedic condition that often involves damage to the bony architecture of the glenohumeral joint in addition to the capsulolabral complex. Patients with recurrent shoulder dislocations are at increased risk for glenohumeral bone loss, as each instability event leads to the accumulation of additional glenoid and/or humeral head bone defects. Depending on the degree of bone loss, successful treatment may need to address bony lesions in addition to injured soft-tissue structures. As such, a thorough understanding of methods for evaluating bone loss preoperatively, in terms of location, size, and significance, is essential. Although numerous imaging modalities can be used, three-dimensional imaging has proven particularly useful and is now an integral component of preoperative planning.

Evaluation of factors associated with successful 5-year outcomes following arthroscopic Bankart repair in athletes. Knee Surg Sports Traumatol Arthrosc 2022; 30:2092-2098. [PMID: 34811577 DOI: 10.1007/s00167-021-06803-5] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/26/2021] [Accepted: 11/11/2021] [Indexed: 10/19/2022]
Abstract
PURPOSE The purpose of this study was to evaluate the outcomes of athletes 5-years post-operatively following arthroscopic Bankart repair, and to evaluate factors associated with satisfaction and shoulder function, as defined by subjective shoulder value. METHODS A retrospective review of athletes who underwent arthroscopic Bankart repair, with a minimum of 5-year follow-up was performed. Recurrence, Visual Analogue Scale (VAS) score, Subjective Shoulder Value (SSV), satisfaction, and whether they would undergo the same surgery again, and rate, level and timing of return to play, and Shoulder Instability-Return to Sport after Injury (SIRSI) score were evaluated. Multi-linear regression models were used to evaluate factors affecting postoperative Satisfaction, and SSV level. RESULTS Overall, 144 athletes who underwent arthroscopic Bankart repair were included, with a mean age of 26.9 years (SD: 8.1), 132 (91.7%) were males, and mean follow-up of 75.7 months. At final follow up, 82.6% were satisfied/very satisfied, and the mean SSV was 85.8 (SD: 14.4). Overall, the rate of return to play was 80.5%, with 63.9% returning at the same level at a mean of 6.2 months (SD: 2.7). Overall, there was 18 (12.5%) had recurrent instability, and a further procedure was performed in 15 (10.4%) patients. Linear regression revealed that the SIRSI score (p < 0.0001), SSV (p < 0.0001), VAS (p < 0.0031), no sleep trouble (p = 0.0129) was associated with satisfaction. Logistic regression revealed whether a patient required revision surgery (p = 0.0029), or had re-dislocation (p = 0.0031) was also associated with satisfaction. Linear regression revealed that the SIRSI score (p < 0.0001), VAS score (p < 0.0001), and no sleep trouble (p < 0.0001), were associated with SSV score. CONCLUSION There was a high rate of satisfaction at 5-year follow-up, with excellent patient-reported outcomes and a high rate of return to play among athletes. However, there was a moderate rate of recurrent instability and further revision surgery. This study identified that the SIRSI score, VAS score, no sleep trouble and ability to return to play at the same level were associated with both satisfaction and SSV score. LEVEL OF EVIDENCE III.

No Difference in Outcomes After Arthroscopic Bankart Repair With Remplissage or Arthroscopic Latarjet Procedure for Anterior Shoulder Instability. Arthrosc Sports Med Rehabil 2022; 4:e853-e859. [PMID: 35747622 PMCID: PMC9210364 DOI: 10.1016/j.asmr.2021.12.011] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2020] [Accepted: 12/13/2021] [Indexed: 11/23/2022] Open
Abstract
Purpose To evaluate the outcomes of arthroscopic Bankart repair with remplissage (ABRR) compared with the arthroscopic Latarjet (AL) procedure for anterior shoulder instability in patients with a labral tear and a concomitant engaging Hill-Sachs lesion. Methods A retrospective review of patients who underwent either ABRR or the AL procedure for a diagnosis of anterior shoulder instability with a concomitant engaging Hill-Sachs lesion between 2011 and 2019 was performed. Recurrent instability, the visual analog scale score, the Subjective Shoulder Value, the Western Ontario Shoulder Instability score, patient satisfaction, willingness to undergo surgery again, and return to work or sport were evaluated. Results Our study included 41 patients treated with ABRR and 26 treated with the AL procedure. At final follow-up, there was no difference between patients who underwent ABRR and those who underwent the AL procedure in the reported Western Ontario Shoulder Instability score (21.8% vs 28.2%, P = .33) or any of its components, the visual analog scale score (0.9 vs 1.4, P = .32), the Subjective Shoulder Value (78.4 vs 74.5, P = .6062), the rate of satisfaction (81.6% vs 85.6%, P = .54), or whether patients would undergo surgery again (81.6% vs 96.1%, P = .16). Overall, 5 patients in the ABRR group and 2 patients in the AL group had recurrent instability events (12.2% vs 7.8%, P = .70), with no significant difference in the rate of recurrent dislocation (12.2% vs 3.8%, P = .39). Conclusions In patients with anterior shoulder instability and a concomitant Hill-Sachs lesion, both ABRR and the AL procedure were shown to be reliable treatments, with a low rate of recurrent instability and excellent patient-reported outcomes in appropriately selected patients. However, our study could not determine whether there was critical glenoid bone loss in patients undergoing ABRR, and surgeons should still exercise caution in performing ABRR in patients with high-grade glenoid bone loss or in those with failed prior stabilizations.

Abstract
BACKGROUND Debate centering on the management of anterior shoulder instability (ASI) in recent years has led to many randomized controlled trials (RCTs) being published on the topic. The fragility index (FI) has subsequently emerged as a novel method of assessing significant findings reported in RCTs, particularly those with small sample sizes. PURPOSE To evaluate the FI of statistically significant findings in RCTs that reported the outcomes of management strategies of patients with ASI. STUDY DESIGN Systematic review; Level of evidence, 1. METHODS Using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, 2 independent reviewers performed a systematic review of RCTs focusing on the outcomes of management strategies of patients with ASI. There were 3 main categories of RCTs included: (1) nonoperative management in internal rotation (IR) versus external rotation (ER), (2) nonoperative management versus a surgical intervention, and (3) surgical management with arthroscopic Bankart repair versus open Bankart repair. The Fisher exact test was utilized to calculate the FI for the reversal of statistical significance in all statistically significant dichotomous outcomes. RESULTS A total of 21 RCTs were included, including 1589 shoulders (mean age, 29.4 years) with a mean follow-up of 26.8 months. There were 10 RCTs (831 shoulders) that reported outcomes after the nonoperative management of ASI in IR versus ER, with a mean FI of 6.8. There were 5 RCTs (324 shoulders) that reported outcomes comparing the nonoperative and operative management of ASI, with a mean FI of 3.5. There were 6 RCTs (434 shoulders) that reported outcomes after the operative management of ASI with either arthroscopic Bankart repair or open Bankart repair, with a mean FI of 9.6. CONCLUSION The overall FI of RCTs reporting the outcomes of management strategies for patients with ASI was high, suggesting a moderate fragility of statistically significant outcomes including recurrence, revision stabilization, and return to play.

Abstract
Background: The Latarjet procedure is indicated in patients with risk factors for postoperative recurrence, including collision and competitive athletes. However, the factors that prevent athletes from being able return to play (RTP) after the open Latarjet procedure are still unclear and have not been fully elucidated in the literature. Purpose: To evaluate patient-reported outcomes and psychological and psychosocial factors associated with athletes who did not RTP after the open Latarjet procedure compared with patients who did RTP. Study Design: Cohort study; Level of evidence, 3. Methods: We conducted a retrospective review of athletes who underwent the open Latarjet procedure and subsequently did not RTP after a minimum of 12 months. These patients were pair matched in a 2:1 ratio for age, sex, sport, and level of preoperative play with a control group who returned to play. Patients were evaluated for their psychological readiness to return to sport using the Shoulder Instability–Return to Sport after Injury (SIRSI); other measures included the visual analog scale (VAS) for pain and Subjective Shoulder Value (SSV). Multivariate regression models were used to evaluate factors affecting RTP. Results: Included were 35 patients in the no-RTP group and 70 patients in the RTP group. In the no-RTP group, 7 patients (20%) passed the SIRSI benchmark of 56, with a mean overall score of 41.5 ± 21.9; in the RTP group, 57 patients (81.4%) passed the SIRSI benchmark, with a mean overall score of 74.5 ± 19.8 (P < .0001 for both). Patients in the RTP group had better SSV (88.0 vs 75.7; P <.0001) and VAS pain (1.7 vs 2.9; P = .0046) scores. Of the athletes who did not return, 18 felt persistent pain/apprehension and 17 felt that it was a natural end to their career or that their lifestyle had changed. Multiple logistic regression revealed that thoughts of having to go through surgery and rehabilitation again was significantly associated with lower RTP (P < .05). Conclusion: Patients who did not RTP after open Latarjet exhibited poor psychological readiness to RTP and worse pain VAS and SSV scores compared with patients who did RTP.

Abstract
BACKGROUND Humeral avulsion glenohumeral ligament (HAGL) lesions are often underreported but have been shown to occur in up to 10% of cases of anterior shoulder instability. PURPOSE To compare clinical outcomes and recurrence rates of patients with HAGL lesions undergoing open stabilization for anterior shoulder instability versus a pair-matched control. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS A retrospective review of all patients who underwent both arthroscopic and open stabilization procedures with a minimum 24-month follow-up was performed. Patients with HAGL lesions were pair-matched in a 1:6 ratio for age, sex, sport, level of preoperative play, and follow-up length with those without HAGL lesions who underwent arthroscopic Bankart repair alone. Return to play (RTP), the level of return, and the timing of return were assessed. In addition, recurrence, visual analog scale for pain (VAS), Subjective Shoulder Value (SSV), Rowe score, satisfaction, and whether they would undergo the same surgery again were compared. RESULTS A total of 15 patients with HAGL lesions who underwent shoulder stabilization procedures were included, with a mean age of 21.5 ± 4.1 years and mean follow-up of 53.5 ± 17.4 months, and were pair-matched to 90 patients without HAGL lesions. Overall, there was no significant difference in any of the clinical outcome scores (VAS, Rowe, SSV, satisfaction) used between the 2 groups (1.6 vs 1.7, P = .86; 83.4 vs 88.0, P = .06; 85.7 vs 87.2, P = .76; and 86.7% vs 94.5%, P = .26, respectively). In addition, there were no significant differences in terms of overall rates, levels, and timing of RTP between the 2 groups (93.3% vs 90.0%, P > .99; 80.0% vs 78.9%, P > .99; and 5.3 ± 2.2 vs 5.9 ± 2.9 months, P = .45, respectively). There was no significant difference in the rates of apprehension, subluxation, and recurrent instability between the HAGL and pair-matched control groups (26.7% vs 26.7%, P > .99; 6.7% vs 3.3%, P = .47; and 13.3% vs 6.7% months, P = .32, respectively). CONCLUSION Patients with anterior shoulder instability undergoing surgical stabilization with open HAGL repair demonstrate excellent functional outcomes and high rates of RTP, with low rates of recurrence in the medium term compared with a control group without HAGL lesions who underwent arthroscopic Bankart repair alone.

Recurrence in traumatic anterior shoulder dislocations increases the prevalence of Hill-Sachs and Bankart lesions: a systematic review and meta-analysis. Knee Surg Sports Traumatol Arthrosc 2022; 30:2130-2140. [PMID: 34988633 PMCID: PMC9165262 DOI: 10.1007/s00167-021-06847-7] [Citation(s) in RCA: 18] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/16/2021] [Accepted: 12/13/2021] [Indexed: 11/25/2022]
Abstract
PURPOSE The extent of shoulder instability and the indication for surgery may be determined by the prevalence or size of associated lesions. However, a varying prevalence is reported and the actual values are therefore unclear. In addition, it is unclear whether these lesions are present after the first dislocation and whether or not these lesions increase in size after recurrence. The aim of this systematic review was (1) to determine the prevalence of lesions associated with traumatic anterior shoulder dislocations, (2) to determine if the prevalence is higher following recurrent dislocations compared to first-time dislocations and (3) to determine if the prevalence is higher following complete dislocations compared to subluxations. METHODS PubMed, EMBASE, Cochrane and Web of Science were searched. Studies examining shoulders after traumatic anterior dislocations during arthroscopy or with MRI/MRA or CT published after 1999 were included. A total of 22 studies (1920 shoulders) were included. RESULTS The proportion of Hill-Sachs and Bankart lesions was higher in recurrent dislocations (85%; 66%) compared to first-time dislocations (71%; 59%) and this was statistically significant (P < 0.01; P = 0.05). No significant difference between recurrent and first-time dislocations was observed for SLAP lesions, rotator-cuff tears, bony Bankart lesions, HAGL lesions and ALPSA lesions. The proportion of Hill-Sachs lesions was significantly higher in complete dislocations (82%) compared to subluxations (54%; P < 0.01). CONCLUSION Higher proportions of Hill-Sachs and Bankart were observed in recurrent dislocations compared to first-time dislocations. No difference was observed for bony Bankart, HAGL, SLAP, rotator-cuff tear and ALPSA. Especially when a Hill-Sachs or Bankart is present after first-time dislocation, early surgical stabilization may need to be considered as other lesions may not be expected after recurrence and to limit lesion growth. However, results should be interpreted with caution due to substantial heterogeneity and large variance. LEVEL OF EVIDENCE IV.

Abstract
PURPOSE The aim of the current study was to compare the diagnostic precision and reliability of different methods in measuring Hill-Sachs lesions (HSLs) using MRI and CT. METHODS A total of 80 consecutive patients with a history of anterior shoulder instability were retrospectively included. The preoperative CT and MRI scans of the affected shoulders were analysed. To investigate the ability of the Franceschi grading, Calandra classification, Richards, Hall, and Rowe grading scale, Flatow percentage and "glenoid track" assessment according to Di Giacomo et al. to quantify the extent of humeral bone loss, the results of each measurement method obtained with MRI were compared with those achieved with CT. In addition, the intra- and inter-rater reliabilities of each measurement method using CT and MRI were calculated and compared. RESULTS A significant difference was found between CT and MRI in the determination of the Hill-Sachs interval (HSI) (p = 0.016), but not between the results of any of the other measurement techniques. With the exceptions of the Franceschi grade and Calandra classification, all measurement methods showed good or excellent intra- and inter-rater reliabilities for both MRI and CT. CONCLUSIONS While the determination of the HSI with MRI was more accurate, all other analysed techniques for measuring the amount of humeral bone loss showed similar diagnostic precision. With regard to the intra- and inter-rater reliabilities, all measurement techniques analysed, with the exception of the Franceschi and Calandra classifications, provided good to very good reliabilities with both CT and MRI.

Abstract
Background Gaelic Athletic Association (GAA) games are collision sports played at an amateur level, which represent the most popular sports played on the island of Ireland. Each year, many GAA players in Ireland require surgical stabilization with either arthroscopic Bankart repair (ABR) or open Latarjet (OL) procedures in the setting of anterior shoulder instability. The purpose of this study was to evaluate the clinical outcomes, recurrence, and return to play (RTP) in athletes who play GAA games having undergone surgical stabilization with either ABR or OL procedures in the setting of anterior shoulder instability. Methods A retrospective review of all patients with anterior shoulder instability whom had stabilization with either ABR or OL under a single surgeon between 2012 and 2018 was performed. Patients who were athletes partaking in GAA sports were followed up by chart review and telephone survey to assess their clinical outcomes including satisfaction, pain as measured on the visual analog scale score, the Subjective Shoulder Value, recurrence, complications, and revision surgeries. In addition, RTP rates, time to RTP, level of RTP, and Shoulder Instability–Return to Sport after Injury scores were evaluated. Results A total of 200 GAA athletes (194 males) with a mean age of 23.9 ± 6.1 years with mean follow-up of 50.4 ± 24 months were included in this study. A total of 98.1% patients were satisfied with their procedure at the latest follow-up, with an overall recurrence rate of 5%. A total of 6.5% of athletes required revision surgery, of whom 4% required revision stabilization (all of whom had recurrence). The overall rate of RTP was 88% at mean 6.0 ± 1.7 months postoperatively, with 75% of athletes returning at the same or higher levels than their preinjury level. There were no significant differences for all outcome measures analyzed between patients who had ABR or OL procedures. Conclusion GAA athletes with anterior shoulder instability treated with either ABR or OL procedures report excellent clinical outcomes at medium-term follow-up, with high satisfaction rates, excellent functional outcomes, and high rates of RTP. Furthermore, this cohort demonstrates low rates of recurrence after stabilization with few requiring revision surgery.

Abstract
Purpose To compare the outcomes of athletes who have been treated for either primary or recurrent anterior shoulder instability with arthroscopic Bankart repair (ABR). Methods A retrospective review of patients who underwent ABR for anterior shoulder instability, with a minimum of 24 months’ follow-up, was performed. Those who underwent ABR for primary instability were matched in a 1:1 ratio for age, sex, sport, and level of preoperative play to those who underwent ABR for recurrent instability. The rate, level, and timing of return to play (RTP), as well as the Shoulder Instability–Return to Sport After Injury score, were evaluated. Additionally, the recurrence rate, visual analog scale score, Subjective Shoulder Value, Rowe score, satisfaction, and whether patients would undergo the same operation again were compared. Results After analysis of 467 patients, 100 athletes who underwent ABR for primary instability were identified and subsequently pair matched to 100 patients who underwent ABR for recurrent instability, with a mean age of 27.2 years, 87% male patients, 68% collision athletes, and a mean follow-up period of 61.9 months. There was no significant difference between the groups in the rate of RTP (80% vs 79%, P = .86) or RTP at the preinjury level (65% vs 65%, P >. 999); however, there was a significant difference in time to RTP (6.9 ± 2.9 months vs 5.9 ± 2.5 months, P = .02). There were no significant differences in visual analog scale score, Shoulder Instability–Return to Sport After Injury score, Subjective Shoulder Value, Rowe score, patient satisfaction, and whether patients would undergo the operation again (P > .05 for all). There was no difference in the rate of recurrent instability after ABR (10% vs 16%, P = .29). Conclusions ABR results in excellent clinical outcomes, high rates of RTP, and low recurrence rates for both athletes with primary instability and those with recurrent instability. Level of Evidence Level III, retrospective comparative cohort study.

[PMID: 34366225 DOI: 10.1016/j.surge.2021.06.005] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2021] [Revised: 06/07/2021] [Accepted: 06/16/2021] [Indexed: 12/24/2022]
Abstract
PURPOSE The purpose of this study was to analyze patients that did not return to play (RTP) following arthroscopic Bankart repair (ABR) compared to those who did RTP, and analyze factors associated with not returning to play. METHODS A retrospective review of patients who underwent ABR, and subsequently did not RTP after a minimum of 24-month follow-up was performed. Additionally, these were pair matched in a 3:1 ratio for age, gender, sport and level of pre-operative play with a control group who RTP. Patients were evaluated for their psychological readiness to return to sport using the SIRSI score. Multivariate regression models were used to evaluate factors affecting RTP. RESULTS The study included a total of 52 patients who were unable to RTP and 156 who returned to play. Ten patients (19.2 %) who did not RTP passed the SIRSI benchmark of 56 with a mean overall score of 39.8 ± 24.6, in those who returned 73.0 % passed the SIRSI benchmark of 56 with a mean overall score of 68.9 ± 22.0 (p < 0.0001 for both). The most common primary reasons for not returning were 27 felt physically unable to return, whilst 21 felt it was a natural end to their career or their lifestyle had changed. Multi-logistic regression revealed that 4 of the 12 components of the SIRSI score (p < 0.05 for all) and SSV (p = 0.0049), were the factors that were associated with RTP. CONCLUSION Following ABR, those that do not return to play exhibit poor psychological readiness to return to play, with multi-linear regression revealing the SIRSI questions associated with fear of re-injury were associated with a lower rate of RTP. Additionally, functional limitations were found to be associated with a lower rate of RTP. LEVEL OF EVIDENCE Level III; Retrospective Comparative Cohort Study.

Open Latarjet Procedure in Athletes Following Failed Prior Instability Surgery Results in Lower Rates of Return to Play. Arthroscopy 2021; 37:2412-2417. [PMID: 33872743 DOI: 10.1016/j.arthro.2021.03.062] [Citation(s) in RCA: 22] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/11/2020] [Revised: 12/04/2020] [Accepted: 03/22/2021] [Indexed: 02/02/2023]
Abstract
PURPOSE The purpose of this study was to compare the outcomes of open Latarjet (OL) in competitive athletes with primary shoulder instability versus those with recurrent instability versus those undergoing OL for failed prior instability surgery. METHODS A retrospective review of patients who underwent OL with a minimum of 24-month follow-up was performed. Additionally, these were pair-matched in a 1:2:1 ratio for age, gender, sport, level of preoperative play, and follow-up length for primary instability, recurrent instability and failed prior instability surgery. Return to sport, the level of return and the timing of return were assessed. Additionally, recurrence, Visual Analogue Scale for pain (VAS), Subjective Shoulder Value (SSV), Rowe score, Shoulder Instability-Return to Sport after Injury (SIRSI) score, satisfaction, and whether they would undergo the same surgery again were compared. RESULTS After pair-matching, a total of 200 patients were included, with a mean age of 22.7 years and a mean follow-up of 38.8 months. Overall, there was no significant difference in any of the clinical outcome scores (VAS, Rowe, SIRSI, SSV) used for the 3 groups (P > 0.05 for all). However, there was a significantly lower rate of return to play for those undergoing OL because of failed prior instability surgery (88% vs 91% vs 64%, P < 0.0001) and for return at the same or a higher level (66% vs 78% vs 56%, P = 0.02). There was no significant difference in the rate of recurrent instability among the 3 groups (6% vs 5% vs 6%, P = 0.95). CONCLUSION OL results in excellent clinical outcomes and low recurrence rates for those with primary shoulder instability, those with recurrent instability and those undergoing OL for failed prior instability surgery. However, in those undergoing OL for failed prior stabilization surgery, there was a lower rate of return to play. LEVEL OF EVIDENCE Level III: Retrospective Comparative Study.

Return to play criteria among shoulder surgeons following shoulder stabilization. J Shoulder Elbow Surg 2021; 30:e317-e321. [PMID: 33618019 DOI: 10.1016/j.jse.2021.01.026] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/17/2020] [Revised: 01/11/2021] [Accepted: 01/18/2021] [Indexed: 02/07/2023]
Abstract
PURPOSE The purpose of this study was to survey the members of North American and European shoulder surgery and sports medicine societies to evaluate their criteria for deciding when an athlete can safely return to play (RTP) following shoulder stabilization surgery. METHODS A survey was sent to the members of the American Shoulder and Elbow Surgeons (ASES), American Orthopaedic Society for Sports Medicine (AOSSM), European Society for Sports Traumatology, Knee Surgery and Arthroscopy (ESSKA), and European Society for Surgery of the Shoulder and the Elbow (SECEC). Surgeons were asked which criteria they used to determine when an athlete can return to play following the arthroscopic Bankart repair and Latarjet procedures, with additional questions on how time from surgery and participation in collision sports affect return. RESULTS Overall, 317 surgeons responded to the survey. Following arthroscopic Bankart repair, the most common criteria used were time (98.7%), strength (74.8%), and range of motion (70%). The most commonly reported time point was 4 months (43.8%), and the majority used an additional time period, most commonly 2 months (38.2%), before allowing a collision athlete to return to play (75.4%). Interestingly, the addition of a remplissage procedure did not affect decision making regarding RTP in most cases (92.1%). Following the Latarjet procedure, the most common criteria used were time (98.4%), strength (67.5%), and range of motion (65.9%). Less than half reported using imaging to assess for radiographic union before allowing patients to return to play (47%), and the most common modality was plain radiography (80%). The most common time point was 4 months (33.1%), and the majority reported waiting an additional period of time, most commonly by 2 months (25.9%), before allowing a collision athlete to return to play (59.6%). CONCLUSION Despite the absence of evidence-based guidelines on when athletes can safely return to play following shoulder stabilization surgery, there exists minimal variability in recommendations between North American and European shoulder surgeons. Further research is required to better define criteria for RTP after the arthroscopic Bankart repair and Latarjet procedures.

Abstract
BACKGROUND Our aim is to determine the interobserver reliability for surgeons to detect Hill-Sachs lesions on magnetic resonance imaging (MRI), the certainty of judgement, and the effects of surgeon characteristics on agreement. METHODS Twenty-nine patients with Hill-Sachs lesions or other lesions with a similar appearance on MRIs were presented to 20 surgeons without any patient characteristics. The surgeons answered questions on the presence of Hill-Sachs lesions and the certainty of diagnosis. Interobserver agreement was assessed using the Fleiss' kappa (κ) and percentage of agreement. Agreement between surgeons was compared using a technique similar to the pairwise t-test for means, based on large-sample linear approximation of Fleiss' kappa, with Bonferroni correction. RESULTS The agreement between surgeons in detecting Hill-Sachs lesions on MRI was fair (69% agreement; κ, 0.304; p<0.001). In 84% of the cases, surgeons were certain or highly certain about the presence of a Hill-Sachs lesion. CONCLUSIONS Although surgeons reported high levels of certainty for their ability to detect Hill-Sachs lesions, there was only a fair amount of agreement between surgeons in detecting Hill-Sachs lesions on MRI. This indicates that clear criteria for defining Hill-Sachs lesions are lacking, which hampers accurate diagnosis and can compromise treatment.

Abstract
PURPOSE To determine the reliability and accuracy of different imaging modalities in assessing Hill-Sachs lesions within the setting of anterior shoulder instability. METHODS A systematic review was performed according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines using the PubMed, Scopus, Embase, and Cochrane Library databases. The inclusion criteria were clinical trials or cadaveric studies that assessed the accuracy of humeral head bone loss imaging or reliability and English-language articles. The exclusion criteria were animal studies; imaging studies without measures of accuracy, reliability, or clinical predictive power; studies of shoulder injuries without humeral head bone loss; editorials; abstracts; reviews; case reports; and surveys. The search terms included "imaging" OR "radiographic" OR "CT" OR "MRI" AND "Hill-Sachs" OR "humeral head bone loss." Assessment of the methodologic quality of the included studies was performed using the original Quality Assessment of Diagnostic Accuracy Studies (QUADAS) tool. RESULTS Forty studies (2,560 shoulders) met the inclusion criteria and were assessed. For diagnosing the presence of Hill-Sachs lesions, computed tomography (CT) arthrography had the highest reported accuracy (median, 91%; range, 66%-100%). For the same assessment, CT arthrography also had the greatest reported sensitivity (median, 94%; range, 50%-100%). For the quantification of Hill-Sachs lesion parameters, reported intraobserver reliabilities were highest for 3-dimensional (3D) CT (intraclass correlation coefficient [ICC] range, 0.916-0.999), followed by 2-dimensional CT (ICC range, 0.858-0.861) and magnetic resonance imaging (MRI) (ICC range, 0.28-0.97). For the same quantification parameters, interobserver reliabilities were also reported for 3D CT (ICC range, 0.772-0.996), 2-dimensional CT (ICC range, 0.721-0.879), and MRI (κ range, 0.444-0.700). Intraobserver reliabilities for determining glenoid tracking were only reported for 3D CT (κ range, 0.730-1.00; ICC range, 0.803-0.901) and MRI (ICC range, 0.770-0.790). CONCLUSIONS This study shows that the current literature supports a variety of different imaging modalities that provide clinically acceptable accuracy in diagnosing and quantifying Hill-Sachs lesions, as well as determining whether they will cause persistent anterior shoulder instability. Furthermore, this systematic review justifies that further research is needed to help develop a treatment algorithm on the proper imaging modalities needed to help treat patients with anterior shoulder instability that is both reliable and financially acceptable. LEVEL OF EVIDENCE Level IV, systematic review of Level I through IV studies.

Abstract
BACKGROUND Anterior shoulder instability is a common clinical condition that often requires surgical stabilization. Glenoid labral tears are often associated with instability, with glenolabral articular disruption (GLAD) lesions occasionally being identified arthroscopically during repair, particularly in collision athletes. PURPOSE To evaluate the clinical outcomes and recurrence rates in patients who had GLAD lesions and underwent arthroscopic Bankart repair (ABR) and compare them with a control group without GLAD lesions. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS A retrospective review of patients who underwent ABR with GLAD lesions, by a single surgeon between July 2012 and March 2017, was performed. Additionally, these were pair matched in a 2:1 ratio for age, sex, sport, and level of play with a control group who underwent ABR without GLAD lesions. Return to sport, the level of return, and the timing of return were assessed. The visual analog scale (VAS) for pain score, Rowe score, Shoulder Instability-Return to Sport after Injury (SIRSI) score, and Subjective Shoulder Value (SSV) were evaluated. RESULTS The study included a total of 66 patients (22 and 44 patients for the GLAD and control groups, respectively), with a mean age of 25.8 years and a mean follow-up of 66 months. Overall, there was no significant difference in any of the clinical outcome scores (VAS, Rowe, SIRSI, and SSV) utilized for the GLAD and control groups (P > .05 for all). Similarly, there was no significant difference in the total rate of return to play (90.9% vs 88.6%; P > .99) or return at the same/higher level (68.2% vs 72.7%; P = .78). There was no significant difference in timing of return to play (6.3 ± 6.6 months vs 6.4 ± 2.5 months; P = .98). There were 3 cases (13.6%) requiring further surgery (1 revision stabilization, 1 arthroscopic release, and 1 rotator cuff repair) in the GLAD group and 2 cases (4.5%) requiring further surgery (both revision stabilization) in the control group; the difference was not statistically significant (P = .32). CONCLUSION After arthroscopic repair, patients with GLAD lesions had similar midterm outcomes when compared with a control group without GLAD lesions.

Abstract
BACKGROUND A 9-grid scheme has been integrated into the foot and ankle literature to help clinicians and researchers localize osteochondral lesions of the talus (OLTs). We hypothesized that fellowship-trained orthopedic foot and ankle surgeons would have a high rate of intra/inter-observer reliability when localizing OLTs, therefore validating the scheme. METHODS We queried our institution's foot and ankle radiographic database for magnetic resonance images with OLTs. Each MRI was reviewed by the senior author, and 2 key images (widest OLT diameter) from each tangential view were copied and combined onto one slide. Fifty consecutive deidentified images of ankles were then sent to 4 practicing fellowship-trained foot and ankle surgeons. Each was asked to identify which zone the OLT was localized within. A radiologist's report served as the control. Statistical analyses were performed using Cohen and Fleiss kappa tests. RESULTS The reviewers demonstrated majority consensus on 45/50 images with substantial agreement for zones 4 and 6. The interobserver reliability was moderate with a κ = 0.55. The mean intraobserver reliability was substantial, with a κ = 0.79. A musculoskeletal radiologist determined there were 3 lesions in zone 7, 18 lesions in zone 4, and 29 lesions in zone 6. CONCLUSION This study is the first to critically evaluate the 9-grid scheme and its reliability among orthopedic foot and ankle surgeons. Our study found that the 9-grid scheme is an accurate method of localization for OLTs with high intra- and moderate interobserver reliability between surgeons.

Abstract
Background In the setting of anterior shoulder instability, it is important to assess the reliability of orthopaedic surgeons to diagnose pathologic characteristics on the 2 most common imaging modalities used in clinical practice: standard plain radiographs and magnetic resonance imaging (MRI). Purpose To assess the intra- and interrater reliability of diagnosing pathologic characteristics associated with anterior shoulder instability using standard plain radiographs and MRI. Study Design Cohort study (diagnosis); Level of evidence, 3. Methods Patient charts at a single academic institution were reviewed for anterior shoulder instability injuries. The study included 40 sets of images (20 radiograph sets, 20 MRI series). The images, along with standardized evaluation forms, were distributed to 22 shoulder/sports medicine fellowship-trained orthopaedic surgeons over 2 points in time. Kappa values for inter- and intrarater reliability were calculated. Results The overall response rate was 91%. For shoulder radiographs, interrater agreement was fair to moderate for the presence of glenoid lesions (κ = 0.49), estimate of glenoid lesion surface area (κ = 0.59), presence of a Hill-Sachs lesion (κ = 0.35), and estimate of Hill-Sachs surface area (κ = 0.50). Intrarater agreement was moderate for radiographs (κ = 0.48-0.57). For shoulder MRI, interrater agreement was fair to moderate for the presence of glenoid lesions (κ = 0.44), glenoid lesion surface area (κ = 0.35), Hill-Sachs lesion (κ = 0.33), Hill-Sachs surface area (κ = 0.28), humeral head edema (κ = 0.41), and presence of a capsulolabral injury (κ = 0.36). Fair agreement was found for specific type of capsulolabral injury (κ = 0.21). Intrarater agreement for shoulder MRI was moderate for the presence of glenoid lesion (κ = 0.59), presence of a Hill-Sachs lesion (κ = 0.52), estimate of Hill-Sachs surface area (κ = 0.50), humeral head edema (κ = 0.51), and presence of a capsulolabral injury (κ = 0.53), and agreement was substantial for glenoid lesion surface area (κ = 0.63). Intrarater agreement was fair for determining the specific type of capsulolabral injury (κ = 0.38). Conclusion Fair to moderate agreement by surgeons was found when evaluating imaging studies for anterior shoulder instability. Agreement was similar for identifying pathologic characteristics on radiographs and MRI. There was a trend toward better agreement for the presence of glenoid-sided injury. The lowest agreement was observed for specific capsulolabral injuries.

Abstract
OBJECTIVE We investigated whether preglenoid fat thickness can be used as an ancillary sign for preliminary diagnosis of Bankart and its variants on nonarthrographic magnetic resonance imaging. MATERIALS AND METHODS Sixty-eight anterior dislocation patients were included in this retrospective study. Forty-eight patients with Bankart and its variants, as detected by arthroscopy and magnetic resonance arthrography, were included in the study group. The study group was divided into osseous Bankart, labral Bankart, Perthes, and anterior labroligamentous periosteal sleeve avulsion subgroups. Twenty patients with no detected labral pathologies by arthroscopy and magnetic resonance arthrography were included in the control group. In these patients, preglenoid fat tissue thickness at the anteroinferior portion was measured at the level of the glenoid tubercle. Thickness of preglenoid fat tissue was compared between groups with different labral pathologies and those with normal labrum. RESULTS The preglenoid fat tissue thickness was 2.65 ± 1.05 mm in the control group and 0.90 ± 0.59 mm in the study group (P < 0.0001). Patients with preglenoid fat tissue thinner than 1.6 mm showed a significantly increased likelihood of having Bankart and its variants in receiver operating characteristic analysis (sensitivity of 95.8% and specificity of 85%). There was no significant difference in preglenoid fat tissue thickness between the subgroups of the study group (osseous Bankart, labral Bankart, Perthes, and anterior labroligamentous periosteal sleeve avulsion). CONCLUSION Preglenoid fat tissue measurement can be used as an ancillary sign in the diagnosis of Bankart and Bankart variants in glenohumeral instability patients.

Abstract
BACKGROUND Traumatic glenohumeral dislocation of the shoulder is one of the most common shoulder injuries, especially among adolescent athletes. The treatment of instability for young athletes continues to be controversial owing to high recurrence rates. PURPOSE To investigate the recurrence rate of shoulder instability after arthroscopic capsulolabral repair for adolescent contact and collision athletes. STUDY DESIGN Case series; Level of evidence, 4. METHODS Sixty-seven patients aged <18 years underwent an arthroscopic labral repair over a 5-year period. The mean ± SD age of the cohort was 16.3 ± 0.9 years (range, 14-17 years) and consisted of 1 female and 66 males. All patients were contact athletes, with 62 of 67 playing rugby. Demographic, clinical, and intraoperative data for all patients with shoulder instability were recorded in our database. Recurrence rates were recorded and relative risks calculated. RESULTS At a follow-up of 33 ± 20 months, 34 of 67 patients had recurrent instability for an overall recurrence rate of 51% among adolescent contact athletes after arthroscopic labral repair surgery. The mean time to recurrence was 68.1 ± 45.3 weeks. All recurrences occurred as a result of a further sporting injury. Relative risk analysis demonstrated that athletes aged <16 years had 2.2 (95% CI, 1.2-2.1) times the risk of developing a further instability episode as compared with athletes aged ≥16 years at the time of index surgery ( P = .0002). The recurrence rate among adolescent athletes after bony Bankart repairs was 57.9% versus 47.9% for soft tissue labral repairs ( P = .4698). The incidence of Hill-Sachs lesions ( P = .0002) and bony Bankart lesions ( P = .009) among adolescent athletes was significantly higher than among adult controls ( P = .002). The presence of bone loss did not lead to a significant increase in recurrence rate over and above the effect of age. CONCLUSION Adolescent contact athletes undergoing arthroscopic labral repair have an overall recurrence rate of 51%. Rugby players who undergo primary arthroscopic shoulder stabilization aged <16 years have 2.2 times the risk of developing a further instability episode when compared with athletes aged ≥16 years at the time of index surgery, with a recurrence rate of 93%.

Abstract
Background: The glenohumeral joint combines large range of motion and insufficient bony stabilization, making it susceptible to instability and dislocations. Arthroscopic surgery is routinely used as a diagnostic tool and has been considered the gold standard for the diagnosis of shoulder lesions. However, several studies have demonstrated variability in intraobserver and interobserver agreement. Purpose: To evaluate interobserver and intraobserver agreement in the assessment of intra-articular lesions associated with shoulder instability among fellowship-trained shoulder surgeons. Study Design: Cohort study (diagnosis); Level of evidence, 3. Methods: A total of 24 arthroscopic videos from patients treated for recurrent shoulder instability were shown to a group of 10 fellowship-trained shoulder surgeons who are members of the Multicenter Orthopaedic Outcomes Network (MOON) Shoulder Group. They were presented to the surgeons on 2 different occasions at least 2 months apart. They were asked to classify labral tears by their position, type, extension, other intra-articular abnormality, and preferred treatment. No patient history or physical examination data were provided. The primary outcome was the median overall percentage of agreement for the surgeons performing a video review, measured for each variable evaluated. Intraclass correlation coefficients were used to evaluate continuous variables, and kappa values were used for categorical items. Results: Interobserver agreement was good for anterior labral lesions; good for Hill-Sachs lesions; and moderate for lesions of the superior labrum, posterior labrum, anterior sublabral foramen, and position and extension of the tear. Intraobserver agreement was either good or very good for all variables evaluated, except for being poor for inferior labral lesions and moderate for lesions of the meniscoid superior labrum. Conclusion: Interobserver and intraobserver reliability for the arthroscopic assessment of labral tears in patients with recurrent shoulder instability were good to moderate for the majority of anatomic structures assessed. There was relatively good agreement between shoulder instability surgeons on assessing and documenting shoulder instability–associated abnormalities. These findings are important when interpreting collaborative clinical cohort studies with numerous surgeons involved in the research.

Abstract
BACKGROUND Accurate assessment of Hill-Sachs lesions (HSLs) and their relationship to the glenoid track is essential to optimizing management following traumatic shoulder dislocation. The purpose of this study was to measure the size of HSLs by a novel method with magnetic resonance (MR) arthrography and to investigate the relationship between lesion size and instability history in adolescents (below 19 y of age) with a history of traumatic dislocation. METHODS All shoulder MR arthrograms queried to identify HSLs over a 4-year period were retrospectively reviewed and independently evaluated by 2 blinded musculoskeletal radiologists. HSLs were evaluated on axial T1-weighted fat-saturated images. For each consecutive image slice in which the HSL was identified, a freehand region of interest was constructed along the compression fracture cavity. Region of interest sum was multiplied by image slice thickness (and gap between slices if present) to generate a total HSL volume (mm). Subject chart review was then performed to acquire demographic data, including shoulder dislocation history. RESULTS A total of 30 patients met inclusion criteria and included 22 boys (mean age, 16.3 y) and 8 girls (mean age, 16.4 y). Four patients had a history of 1 traumatic dislocation, 12 had a history of 2, and 14 had a history of ≥3. The average size of the HSL for all patients was 3.8 mm (range, 0.52 to 11 mm). There was no significant difference in HSL volume between the 21 skeletally immature (3.7 mm) and 9 skeletally mature (4.2 mm) patients (P=0.67). Patients with a history of 1, 2, or 3+ dislocations had an average HSL volume of 1.3, 3.7, and 4.7 mm, respectively. The measurement method revealed excellent interreader reliability (P=0.00). There was a statistically significant difference between dislocation history group mean HSL volumes (P=0.019), as well as a statistically significant difference between the number of dislocations and lesion volume (P=0.011). CONCLUSIONS HSLs can be effectively measured in adolescent patients using MR arthrography and patients with larger HSLs have more recurrent instability episodes, potentially meriting greater and earlier attention to the defect. LEVEL OF EVIDENCE Prognostic/diagnostic study level IV.

Imaging methods for quantifying glenoid and Hill-Sachs bone loss in traumatic instability of the shoulder: a scoping review. BMC Musculoskelet Disord 2015; 16:164. [PMID: 26187270 PMCID: PMC4506419 DOI: 10.1186/s12891-015-0607-1] [Citation(s) in RCA: 61] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/17/2014] [Accepted: 05/28/2015] [Indexed: 01/01/2023] Open
Abstract
Background Glenohumeral instability is a common problem following traumatic anterior shoulder dislocation. Two major risk factors of recurrent instability are glenoid and Hill-Sachs bone loss. Higher failure rates of arthroscopic Bankart repairs are associated with larger degrees of bone loss; therefore it is important to accurately and reliably quantify glenohumeral bone loss pre-operatively. This may be done with radiography, CT, or MRI; however no gold standard modality or method has been determined. A scoping review of the literature was performed to identify imaging methods for quantifying glenohumeral bone loss. Methods The scoping review was systematic in approach using a comprehensive search strategy and standardized study selection and evaluation. MEDLINE, EMBASE, Scopus, and Web of Science were searched. Initial selection included articles from January 2000 until July 2013, and was based on the review of titles and abstracts. Articles were carried forward if either reviewer thought that the study was appropriate. Final study selection was based on full text review based on pre-specified criteria. Consensus was reached for final article inclusion through discussion amongst the investigators. One reviewer extracted data while a second reviewer independently assessed data extraction for discrepancies. Results Forty-one studies evaluating glenoid and/or Hill-Sachs bone loss were included: 32 studies evaluated glenoid bone loss while 11 studies evaluated humeral head bone loss. Radiography was useful as a screening tool but not to quantify glenoid bone loss. CT was most accurate but necessitates radiation exposure. The Pico Method and Glenoid Index method were the most accurate and reliable methods for quantifying glenoid bone loss, particularly when using three-dimensional CT (3DCT). Radiography and CT have been used to quantify Hill-Sachs bone loss, but have not been studied as extensively as glenoid bone loss. Conclusions Radiography can be used for screening patients for significant glenoid bone loss. CT imaging, using the Glenoid Index or Pico Method, has good evidence for accurate quantification of glenoid bone loss. There is limited evidence to guide imaging of Hill-Sachs bone loss. As a consensus has not been reached, further study will help to clarify the best imaging modality and method for quantifying glenohumeral bone loss.

Abstract
AIM To prospectively evaluate the influence of observer experience, consensus assessment, and abduction and external rotation (ABER) view on the diagnostic performance of magnetic resonance arthrography (MRA) in patients with traumatic anterior-shoulder instability (TASI). MATERIALS AND METHODS Fifty-eight MRA examinations (of which 51 had additional ABER views) were assessed by six radiologists (R1-R6) and three teams (T1-T3) with different experience levels, using a seven-lesion standardized scoring form. Forty-five out of 58 MRA examination findings were surgically confirmed. Kappa coefficients, sensitivity, specificity, and differences in percent agreement or correct diagnosis (p-value, McNemar's test) were calculated per lesion and overall per seven lesion types to assess diagnostic reproducibility and accuracy. RESULTS Overall kappa ranged from poor (k = 0.17) to moderate (k = 0.53), sensitivity from 30.6-63.5%, and specificity from 73.6-89.9%. Overall, the most experienced radiologists (R1-R2) and teams (T2-T3) agreed significantly more than the lesser experienced radiologists (R3-R4: p = 0.014, R5-R6; p = 0.018) and teams (T2-T3: p = 0.007). The most experienced radiologist (R1, R2, R3) and teams (T1, T2) were also consistently more accurate than the lesser experienced radiologists (R4, R5, R6) and team (T3). Significant differences were found between R1-R4 (p = 0.012), R3-R4 (p = 0.03), and T2-T3 (p = 0.014). The overall performance of consensus assessment was systematically higher than individual assessment. Significant differences were established between T1-T2 and radiologists R3-R4 (p<0.001, p = 0.001) and between T2 and R3 (p<0.001/p = 0.001) or R4 (p = 0.050). No overall significant differences were found between the radiologists' assessments with and without ABER. CONCLUSION The addition of ABER does not significantly improve overall diagnostic performance. The radiologist's experience level and consensus assessment do contribute to higher reproducibility and accuracy.

Abstract
The athlete with a failed instability procedure requires a thoughtful and systematic approach to achieve a good outcome. Goals of treatment should be defined and realistic expectations should be set. Revision stabilization has a high rate of recurrent instability, low rates of return to play, and low clinical outcome scores. Fundamental to successful revision surgery is choosing the correct procedure. The decision is straightforward in athletes with clear factors that predict recurrence (significant glenoid bone loss, engaging Hill-Sachs lesions) because only a bony procedure can restore the articular arc of the glenoid. Arthroscopic revision Bankart repair may be appropriate in those athletes who have an obvious Bankart tear and no bone loss after a traumatic reinjury. The challenge for the shoulder surgeon is identifying the best surgery for the athlete who does not have such clear-cut indications. Each factor that has the potential to lead to a poor outcome needs to be collected and calculated. Patient factors (age, laxity, type and level of sport), injury factors (mechanism of injury, capsulolabral injury, glenoid bone loss, Hill-Sachs lesion), and technical factors (previous surgery performed, integrity of repair, scarring) must be integrated into the treatment algorithm. Based on this collection of factors, the shoulder surgeon should be prepared to provide the athlete with the surgery that provides the best chance to return to playing sports and the lowest risk of recurrent instability.

Value of magnetic resonance arthrography in post-traumatic anterior shoulder instability prior to arthroscopy: a prospective evaluation of MRA versus arthroscopy. Arch Orthop Trauma Surg 2012; 132:371-5.

Abstract
PURPOSE This prospective study was designed to evaluate the value of magnetic resonance arthrography (MRA) after traumatic anterior shoulder instability prior to arthroscopy. METHODS Patients included had two or more shoulder dislocations, at least the first being traumatic. MRA images were scored for Hill Sachs lesions, superior labral anterior posterior (SLAP) lesions, rotator cuff tears, glenohumeral ligament (GHL) lesions and Bankart lesions. Consequently, a standardized shoulder arthroscopy was performed. Five surgeons were involved in the study, initially blinded to the MRA results. MRA and arthroscopic findings were compared. Interobserver agreement was calculated by using Cohen's Kappa coefficients (κ). RESULTS Eighteen patients (13 male, 5 female) were included (mean age 26.1 years). Hill Sachs lesions demonstrated fair agreement (κ = 0.33) whereas for SLAP lesions moderate agreement was calculated (κ = 0.43). On MRA, four partial thickness rotator cuff lesions were seen, not being stated by arthroscopy. GHL lesions were described on MRA in 15 patients; only two patients turned out to have GHL lesions at arthroscopy. Two arthroscopically diagnosed Bankart lesions which needed surgical treatment were not detected by MRA (moderate agreement, κ = 0.47). CONCLUSIONS In patients with post-traumatic anterior glenohumeral instability MRA shows many lesions that can not be confirmed by arthroscopy and therefore do not have therapeutical consequences. On the other hand some labral lesions which do need surgical treatment are not detected on MRA. At least from this study, it can be concluded that MRA has limited value prior to the arthroscopic treatment of post-traumatic shoulder instability.

Abstract
Due to the complexity of shoulder pathomechanics in the overhead athlete, injuries located in the superior aspect of the glenoid, known as superior labral anterior to posterior (SLAP) lesions, are often a surgical and rehabilitation challenge. In an effort to determine surgical versus conservative care of SLAP lesions a thorough clinical examination and evaluation are necessary. If surgery is identified as the treatment of choice, post operative rehabilitation will vary pending surgical findings including the extent and location of the SLAP lesion, and other concomitant findings and procedures. This manuscript will provide an overview of the pathology, examination and evaluation of SLAP lesions, surgical management and post operative rehabilitation following various SLAP categories.

Abstract
BACKGROUND Relative to dislocations, glenohumeral subluxation events have received little attention in the literature, despite a high incidence in young athletes. The pathoanatomy of first-time, traumatic, anterior subluxation events has not been defined, to our knowledge. METHODS As part of a prospective evaluation of all cases of shoulder instability sustained during one academic year in a closed cohort of military academy cadets, a total of thirty-eight first-time, traumatic, anterior glenohumeral subluxation events were documented. Clinical subluxation events were defined as incomplete instability events that did not require a manual reduction maneuver. Twenty-seven of those events were evaluated with plain radiographs and magnetic resonance imaging within two weeks after the injury and constitute the cohort studied. Magnetic resonance imaging studies were independently evaluated by a musculoskeletal radiologist blinded to the clinical history. Arthroscopic findings were available for the fourteen patients who underwent arthroscopic surgery. RESULTS Of the twenty-seven patients who sustained a first-time, traumatic, anterior subluxation, twenty-two were male and five were female, and their mean age was twenty years. Plain radiographs revealed three osseous Bankart lesions and two Hill-Sachs lesions. Magnetic resonance imaging revealed a Bankart lesion in twenty-six of the twenty-seven patients and a Hill-Sachs lesion in twenty-five of the twenty-seven patients. Of the fourteen patients who underwent surgery, thirteen had a Bankart lesion noted during the procedure. Of the thirteen patients who chose nonoperative management, four experienced recurrent instability. Two of the thirteen patients left the academy for nonmedical reasons and were lost to follow-up. The remaining seven patients continued on active-duty service and had not sought care for a recurrent instability event at the time of writing. CONCLUSIONS First-time, traumatic, anterior subluxation events result in a high rate of labral and Hill-Sachs lesions. These findings suggest that clinical subluxation events encompass a broad spectrum of incomplete events, including complete separations of the articular surfaces with spontaneous reduction. A high index of suspicion for this injury in young athletes is warranted, and magnetic resonance imaging may reveal a high rate of pathologic changes, suggesting that a complete, transient luxation of the glenohumeral joint has occurred.

Abstract
BACKGROUND The reported accuracy of clinical tests for superior labral anterior posterior lesions is extremely variable. Pooling results from multiple studies of higher quality is necessary to establish the best clinical tests to use. HYPOTHESIS Certain clinical tests are superior to others for diagnosing the presence or absence of a superior labral anterior posterior lesion. STUDY DESIGN Meta-analysis. METHODS A literature search of MEDLINE (1966-2007), CINAHL (1982-2007), and BIOSIS (1995-2007) was performed for (labrum OR labral OR SLAP OR Bankart) AND (shoulder OR shoulder joint OR glenoid) AND (specificity OR sensitivity AND specificity). Identified articles were reviewed for inclusion criteria. Sensitivity and specificity values were recorded from each study and used for meta-analysis. RESULTS Six of 198 identified studies satisfied the eligibility criteria. Active compression, anterior slide, crank, and Speed tests were analyzed using receiver operating characteristic curves. The accuracy of the anterior slide test was significantly inferior to that of the active compression, crank, and Speed tests. There was no significant difference in test accuracy found among active compression, crank, and Speed tests. Between studies, methodological scores did not significantly affect sensitivity and specificity values. CONCLUSION The anterior slide test is a poor test for detecting the presence of a labral lesion in the shoulder. Active compression, crank, and Speed tests are more optimal choices. Clinicians should choose the active compression test first, crank second, and Speed test third when a labral lesion is suspected.

Abstract
HYPOTHESIS The purpose of this study was to investigate the intraobserver and interobserver reliability of the International Classification of Diseases, Ninth Revision (ICD-9) system when applied to the classification of shoulder instability. MATERIALS AND METHODS From December 2005 through February 2007, 50 patients with shoulder instability were evaluated and classified by an attending physician using one of the 16 ICD-9 codes for shoulder instability. Patients were reassessed after two weeks by the original physician and two additional shoulder specialists. 42 patients completed the study. These data were then analyzed to assess intraobserver and interobserver reliability. RESULTS Intraobserver agreement for ICD-9 codes was 50% (kappa=0.25, fair). Interobserver agreement was 23% (kappa=0.002, poor). DISCUSSION The ICD-9 coding system is the recognized standard for classifying disease states and is used for large epidemiologic studies. The poor agreement demonstrated in this study suggests that the ICD-9 coding system has poor agreement and as such is not a precise method to classify shoulder instability. CONCLUSION Shoulder instability cannot reliably be classified using the ICD-9 coding system. Until a more reliable system is developed, epidemiologic studies of shoulder instability that use ICD-9 codes may be difficult to interpret. LEVEL OF EVIDENCE Level 1; Testing a previously developed classification system.

Abstract
This study evaluated the surgical outcomes of young active patients with arthroscopic Bankart repair within 1 month after first-time anterior shoulder dislocation. From July 2002-October 2004, patients presented with first-time traumatic anterior shoulder dislocation and treated with arthroscopic stabilization within 1 month of injury were retrospectively reviewed. Magnetic resonance imaging and computed tomography were performed before the operation in all cases. Cases with contralateral shoulder multidirectional instability or glenoid bone loss of more than 30% on preoperative computed tomography on the injury side were excluded. All patients were treated with arthroscopic Bankart repair, using metallic suture anchors or soft tissue bio-absorbable anchors by a same group of surgeons and followed the same rehabilitation protocol. Recurrence, instability signs, range of motion, WOSI score, Rowe score and complications were assessed. Thirty-eight patients were recruited: the average age was 21 (16-30). All patients had definite trauma history. Radiologically, all patients had Bankart/Hill-Sachs lesion. All the operations were done within 1 month after injury (6-25 days). The average hospital stay was 1.2 days (1-5 days). The average follow-up was 28 months (24-48 months). There were two cases of posttraumatic re-dislocation (5.2%). The average external rotation lag was 5 degrees (0-15) in 90 degrees shoulder abduction when compared with contralateral side. 95% of patients had excellent or good Rowe score. The average WOSI score was 83%. There was one case of transient ulnar nerve palsy and one case of superficial wound infection. This study concluded that immediate arthroscopic Bankart repair with an accelerated rehabilitation program is an effective and safe technique for treating young active patients with first-time traumatic anterior shoulder dislocation.

Abstract
PURPOSE To retrospectively determine the accuracy of direct magnetic resonance (MR) arthrography of the shoulder in patients with recurrent or residual signs and/or symptoms of instability after prior instability repair, with surgical findings as the reference standard. MATERIALS AND METHODS After institutional ethics review board approval was obtained and informed consent was waived, 40 patients (31 men, eight women; mean age, 28 years) with recurrent instability after previous instability repair who underwent direct shoulder MR arthrography before repeat surgery were studied. Two musculoskeletal radiologists reviewed direct MR arthrographic studies by using consensus agreement in a blinded fashion. MR assessment included evaluation of the labrum (overall, superior, anterior and anteroinferior, posterior and posteroinferior), rotator cuff, biceps tendon, articular cartilage, and presence or absence of a Hill-Sachs lesion. Mean interval between MR arthrography and repeat surgery was 6.2 months (range, 6 days to 36 months). Surgical reports were compared with MR arthrographic results, and accuracy, sensitivity, and specificity of direct MR arthrography were determined. RESULTS Accuracy, sensitivity, and specificity, respectively, of direct MR arthrography in diagnosis of overall labral tears (n = 26) were 91.9%, 96.2%, and 81.8%; those of superior labral tears (n = 16) were 89.2%, 93.8%, and 85.7%; and those of anteroinferior tears (n = 17) were 91.9%, 100%, and 85%. Overall accuracy for detecting rotator cuff injury (n = 17) was 87.2% (sensitivity, 94.1%; specificity, 81.8%); accuracy for biceps injury (n = 7) was 95.7% (sensitivity, 85.7%; specificity, 100%); accuracy for glenoid and/or humeral articular cartilage abnormality (n = 15) was 76.2% (sensitivity, 73.3%; specificity, 83.3%); and accuracy for Hill-Sachs lesion (n = 14) was 93.3%. CONCLUSION Direct MR arthrography is accurate (91.9%) for assessing labral pathologic conditions and other internal derangements of the shoulder in patients with recurrent or residual signs and/or symptoms after prior shoulder instability repair.

Abstract
PURPOSE To evaluate abnormalities and age-related differences after first-time shoulder dislocation. MATERIALS AND METHODS MRA images of first-time dislocators were assessed for labral-ligamentous-capsular / rotator cuff abnormalities and analyzed the age-related differences (< and >/=30 years old). RESULTS Sixty-six patients (34 <30 years old vs. 32 >/=30 years; 51 males; all anterior dislocations) were imaged. Forty-eight patients (73%) showed anteroinferior labral avulsion, consisting of: 6% (4/34 vs. 0/32) Perthes; 23% (8/34 vs. 7/32) free ALPSA (anterior labrum periosteal sleeve avulsion) lesion); 6% (1/34 vs. 3/32) adherent ALPSA; 23% (9/34 vs. 6/32) Bankart; 14% (5/34 vs. 4/32) inferiorly displaced avulsed labrum; 2% (1/34 vs. 0/32) GLAD. Extensive labral detachment (extended above 3 o'clock position) was present in 31% (11/28 vs. 4/20). There were 14% (6/34 vs. 3/32) superior labrum anterior-posterior (SLAP) lesion; 27% (1/34 vs. 17/34) rotator cuff tendon tear; 71% (25/34 vs. 22/32) Hill-Sachs defect. Young patients were more likely to have extensive labral avulsions (P = 0.054), but less likely to have rotator cuff tears (P < 0.001). CONCLUSION A high prevalence and wide variety of labral avulsions after first-time shoulder dislocation, especially adherent ALPSA, inferiorly displaced avulsed labrum, or GLAD lesion, may influence treatment choice and outcome, suggesting a role for early MRA to assist in treatment triage.

Abstract
BACKGROUND Bankart lesions and Hill-Sachs lesions are commonly associated with anterior shoulder dislocations. The presence of Bankart lesion indicates the need for surgical repair. Magnetic resonance imaging (MRI) has been shown to be sensitive in detecting these two lesions. The aim of this study is to investigate the correlation between Bankart lesions and Hill-Sachs lesions on MRI for patients with traumatic anterior shoulder dislocations. METHODS Between 2003 and 2005, 61 patients from Alfred and Sandringham Hospitals had an MRI as part of the investigation for traumatic anterior shoulder dislocations. The MRI scans were reviewed and subsequently confirmed by a radiologist to show the presence or absence of Bankart and Hill-Sachs lesions. The data were then analysed by a statistician. RESULTS Although patients with one of these lesions were more than two-and-a-half times as likely to have the other, small study numbers precluded this result from achieving statistical significance. (odds ratio, 2.67 (0.83-8.61), P = 0.10). Younger age was a strong predictor of a recurrence of shoulder dislocation (odds ratio, 0.93 (0.89-0.98), P = 0.005). The presence of Bankart or Hill-Sachs lesions on MRI for the primary shoulder dislocation group was similar to the recurrent group (73% vs. 72% for Bankart lesion and 67% vs. 70% for Hill-Sachs lesion). CONCLUSION There is a strong correlation between both lesions. This apparent trend can be useful in predicting the presence of a Bankart lesion when a Hill-Sachs lesion is identified on a plain radiograph. This study suggests the consideration of surgical repair after identification of a Hill-Sachs lesion on plain radiographs, especially for younger patients where the rate of re-dislocation is high.
