Yaka H, Erdem TE, Özer M, Kanatli U. Can the presence of SLAP-5 lesions be predicted by using the critical shoulder angle in traumatic anterior shoulder instability? Skeletal Radiol 2024:10.1007/s00256-024-04708-1. [PMID: 38758391 DOI: 10.1007/s00256-024-04708-1] [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: 04/06/2024] [Revised: 05/03/2024] [Accepted: 05/12/2024] [Indexed: 05/18/2024]
Abstract
OBJECTIVE Although SLAP-5 lesions are associated with recurrent dislocations, their causes and pathomechanisms have not been fully elucidated. This study aimed to investigate the association between SLAP-5 lesions and scapular morphology in traumatic anterior shoulder instability (ASI). We hypothesized that there may be a relationship between SLAP-5 lesions and scapular morphology in traumatic ASI patients. MATERIALS AND METHODS The study included 74 patients with isolated Bankart lesions and 69 with SLAP-5 lesions who underwent arthroscopic labral repair for ASI. Critical shoulder angle (CSA) was measured on the roentgenograms, while glenoid inclination (GI) and glenoid version (GV) were measured on magnetic resonance imaging (MRI) by two observers in two separate sessions blinded to each other. Both groups were compared in terms of CSA, GI, and GV. RESULTS The mean ages of Bankart and SLAP-5 patients were 28.4±9.1 and 27.9±7.7 (P=0.89), respectively; their mean CSA values were 33.1°±2.6° and 28.2°±2.4°, respectively (P<0.001). The ROC analysis's cut-off value was 30.5°, with 75.0% sensitivity and 76.7% specificity (AUC = 0.830). SLAP-5 lesions were more common on the dominant side than isolated Bankart lesions (P=0.021), but no difference was found between the groups in terms of GI and GV (P=0.334, P=0.081, respectively). CONCLUSIONS In ASI, low CSA values appeared to be related to SLAP-5 lesions, and the cut-off value of CSA for SLAP lesion formation was 30.5° with 75.0% sensitivity and 76.7% specificity. Scapula morphology may be related to the SLAP-5 lesions, and CSA can be used as an additional parameter in provocative diagnostic tests and medical imaging techniques for the detection of SLAP lesions accompanying Bankart lesions. LEVEL OF EVIDENCE III retrospective case-control study.

J Shoulder Elbow Surg 2023; 32:1812-1818. [PMID: 37419438 DOI: 10.1016/j.jse.2023.05.029] [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: 11/14/2022] [Revised: 05/07/2023] [Accepted: 05/21/2023] [Indexed: 07/09/2023]
Abstract
BACKGROUND The purpose of this study was to compare lesion prevalence and treatment outcomes in patients with primary and recurrent anterior shoulder instability. METHODS Patients who were admitted to the institution with a diagnosis of anterior shoulder instability and who underwent arthroscopic surgery between July 2006 and February 2020 were retrospectively evaluated. Minimum follow-up duration of the patients was 24 months. The recorded data and magnetic resonance imaging (MRI) of the patients were examined. Patients aged ≥40 years, with a history of shoulder region fracture, inflammatory arthritis, a history of epilepsy, multidirectional instability, nontraumatic dislocation, and off-track lesions were excluded from the study. Shoulder lesions were documented and patient outcome evaluation was made with the Oxford Shoulder Score (OSS) and visual analog scale (VAS). RESULTS A total of 340 patients were included in the study. The mean age of patients was 25.6 years (±6.49). The recurrent instability group had a significantly higher rate of anterior labroligamentous periosteal sleeve avulsion (ALPSA) lesions compared to the primary instability group (40.6% vs. 24.6% respectively) (P = .033). Twenty-five patients (43.9%) had superior labrum anterior and posterior (SLAP) lesions in the primary instability group and 81 patients (28.6%) had SLAP lesions in the recurrent instability group (P = .035). OSS increased for both primary (from 35 [16-44] to 46 [36-48]) (P = .001) and recurrent instability groups (from 33 [6-45] to 47 [19-48]) (P = .001). There was no significant difference between the groups regarding postoperative VAS and OSS scores (P > .05). CONCLUSIONS Successful results were obtained in patients younger than 40 years with both primary and recurrent anterior shoulder instability after arthroscopic treatment. ALPSA lesion prevalence was higher whereas SLAP lesion prevalence was lower in patients with recurrent instability. Although the postoperative OSS was comparable between the patient groups, the failure rate was higher in the recurrent instability patients.

Abstract
BACKGROUND Anterior shoulder instability is typically characterized by detachment of the anteroinferior labrum (Bankart lesion). Some patients also sustain a superior labrum anterior-to-posterior (SLAP) injury. The purpose of this study was to compare the medium-term clinical results of isolated anterior Bankart repairs (ABR) with those of combined Bankart and SLAP repair (ABR + SLAP). METHODS Data on all patients treated surgically for recurrent anterior shoulder instability between 2006 and 2011 were retrospectively collected from medical charts. The minimum follow-up was 5 years. Patients were interviewed to assess patient-reported outcome measurements (PROM) as determined by the American Shoulder and Elbow Surgeons Score (ASES), the Subjective Shoulder Score (SSV), and the Disabilities of the Arm, Shoulder, and Hand Score (DASH), as well as their quality of life (QOL: SF12 questionnaire). Information on complications, re-operations, and recurrent instability was recorded and evaluated as well. RESULTS A total of 150 patients (88% males) with a mean age 23.7 years (range 15-40) were included. Forty-two patients following ABR + SLAP repair were compared to 108 patients following ABR alone, with a mean follow-up of 7.8 years (range 5-10.7). The rate of re-dislocation was similar in both groups (26% for ABR + SLAP vs 20% for ABR, p = .44). There were no significant differences in functional outcome between the ABR + SLAP and the ABR alone groups (SSV 86.7 vs 86.5, p = .93, ASES 89.6 vs 86.5, p = .11, and DASH 4.9 vs 7, p = .17), or in QOL outcome (SF12 physical 95.6 vs 93.3, p = .27, SF12 mental 84.4 vs 85.7, p = .63). CONCLUSION Surgical repair for anterior shoulder instability and a coexisting SLAP lesion yields clinical results as good as those of isolated ABR, as evidenced by similar PROM and re-dislocation rates after medium-term follow-up.

Short- and long-term outcomes in Bankart repair vs. conservative treatment for first-time anterior shoulder dislocation: a systematic review and meta-analysis of randomized controlled trials. J Shoulder Elbow Surg 2022; 31:1751-1762. [PMID: 35398165 DOI: 10.1016/j.jse.2022.02.032] [Citation(s) in RCA: 18] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/30/2021] [Revised: 02/12/2022] [Accepted: 02/24/2022] [Indexed: 02/01/2023]
Abstract
BACKGROUND First-time anterior shoulder dislocations are associated with a high rate of residual instability. Therefore, many surgeons support initial Bankart repair surgery over conservative management to address this issue. However, the optimal treatment remains controversial because of uncertainty regarding long-term surgical outcomes. The primary objective of this systematic review and meta-analysis was to compare the short- and long-term rates of residual instability following Bankart repair or conservative management after a first-time anterior shoulder dislocation. METHODS PubMed/MEDLINE, Embase, The Cochrane Library, Web of Science, CINAHL, and ScienceDirect databases were accessed for randomized controlled trials (RCTs) comparing Bankart repair to conservative management. RoB (Risk of Bias) 2 was used to check study quality. The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) guidelines were followed in assessing primary outcomes. The inverse-variance method for continuous variables and the Mantel-Haenszel method for dichotomous variables was used. RESULTS A total of 348 patients from 6 RCTs published across 8 articles, with a mean age of 23.7 years, were included. Bias was graded low in 3 studies, some concerns in 3 studies, and high in 2 studies. In the short term (2-3 years), surgery lowered recurrent instability (risk ratio [RR] 0.15, 95% confidence interval [CI] 0.08, 0.27; I2 = 0%; P < .0001). Similar findings were seen in the long term (5-12 years) (RR 0.23, 95% CI 0.14, 0.39; I2 = 0%; P < .0001). No difference was observed in return to sport (RR 1.18, 95% CI 0.91, 1.52; I2 = 78%; P = .21). Initial surgery lowered subsequent stabilization surgery in the short (RR 0.19, 95% CI 0.09, 0.43; I2 = 0%; P < .0001) and long term (RR 0.17, 95% CI 0.07, 0.39; I2 = 25%; P < .0001). Western Ontario Shoulder Instability Index (WOSI) scores did not differ in the short term (MD, 2.54, 95% CI -0.51, 5.59; I2 = 48%; P = .1) but were higher in the surgical group at long-term follow-up. Patient satisfaction was also higher with surgery (RR 1.75, 95% CI 1.4, 2.2; I2 = 88%; P < .0001). Certainty of evidence was low for only 1 long-term outcome measure. CONCLUSION Bankart repair surgery for first-time anterior shoulder dislocation results in a large reduction in the risk of recurrent shoulder instability and subsequent stabilization surgery in both short- (2-3 years) and long-term (5-12 years) follow-up intervals. Additionally, slight improvements in overall patient satisfaction and WOSI score can be seen at long-term follow-up. However, surgical intervention failed to significantly improve the rate of return to sport when compared with conservative management.

Abstract
INTRODUCTION Concomitant rotator cuff tear and glenohumeral instability in a large cohort of young and active patients has not been examined. The purpose of this study was to investigate the incidence, associated variables, and outcomes in military cadets undergoing shoulder stabilization procedures with these concomitant pathologies. METHODS A retrospective cohort study of a consecutive series of collegiate patients who underwent shoulder stabilization from 2014 to 2018 at a single service academy was conducted. Exclusion criteria were noncadets, revision instability cases, multidirectional instability, and prior rotator cuff repair. A nested case-control analysis was done in a matched series of patients with and without MRI evidence of rotator cuff tear. Baseline demographics, VAS pain scale, physical therapy duration, and time to surgery were analyzed. Postoperative metrics included rate of recurrent instability, subjective outcomes, VAS pain scale, and military-specific criteria. RESULTS Three hundred twenty-four cadets met the inclusion criteria, including 272 men and 52 women averaging 20.53 ± 1.80 years of age. MRI demonstrated concomitant rotator cuff tears in 5.56% of cases. A matched case-control comparison between patients with (rotator cuff tear group) and without (no rotator cuff tear group) rotator cuff tear showed no differences in preoperative data, recurrent instability rate, or postoperative VAS pain scores (0.24 versus 0.88, P = 0.207) at mean 44-month follow-up. Fifteen of 17 patients (88.2%) in each group returned to full activity (P > 0.999). No patients failed to graduate due to shoulder concerns. No patients in the rotator cuff tear group underwent a medical board for separation from the military compared with 2 (11.8%) in the no rotator cuff tear group (P = 0.163). CONCLUSIONS The incidence of concomitant rotator cuff tears in this study of military cadets undergoing shoulder stabilization was 5.56%. In a matched cohort comparison, the presence of a rotator cuff tear on preoperative MRI was not associated with inferior clinical outcomes.

Abstract
OBJECTIVE To summarize the relationship between shoulder instability and superior labrum anterior posterior (SLAP) lesion. METHODS The characteristics of shoulder instability and SLAP lesion were analyzed, and the relationship between them in pathogenesis, clinical symptoms, and biomechanics was discussed by referring to relevant domestic and foreign literature. RESULTS Shoulder instability and SLAP lesion can occur both spontaneously and respectively. SLAP lesion destroys the superior labrum integrity and the long head of biceps tendon (LHBT) insertion, causing excessive humeral head displacement against glenoid, and leading to shoulder instability. While chronic repetitive or acute high-energy traumatic shoulder instability can in turn aggravate SLAP lesion, resulting in expansion and increased degree of the original lesion. CONCLUSION SLAP lesion destroys mechanisms of shoulder stability, while shoulder instability causes tears of the upper labrum and the LHBT, showing a connection between shoulder instability and SLAP lesion. However, the existing evidence can only demonstrate that shoulder instability and SLAP lesion induce and promote the development of each other, instead of a necessary and sufficient condition. Therefore, the specific causal relationship between the two remains unknown and needs to be further studied.

Abstract
BACKGROUND The risk of recurrence after the first episode of anterior shoulder dislocation is high with nonoperative treatment in younger patients. PURPOSE/HYPOTHESIS The aim of this study was to compare the results of arthroscopic Bankart repair and nonoperative treatment for shoulder dislocation in patients younger than 25 years, with a minimum of 2 years of follow-up. The hypothesis was that surgery would decrease the risk of recurrence. STUDY DESIGN Randomized controlled trial; Level of evidence, 1. METHODS We included patients aged between 18 and 25 years after a first episode of anterior shoulder dislocation and divided them into 2 groups. The first group was treated surgically with an arthroscopic Bankart repair within 2 weeks after the dislocation; the second group was treated nonoperatively. Both groups were immobilized for 3 weeks in internal rotation and followed the same physical therapy protocol. Standard radiography and computed tomography were performed immediately after reduction of the dislocation, and follow-up was performed at 3, 6, 12, and 24 months. The primary outcome measure was instability recurrence, defined as another anterior shoulder dislocation requiring closed reduction by another person (the patient was unable to reduce the dislocated joint themselves), a subluxation, or a positive apprehension test. Secondary outcome measures included range of motion, return to sport, and functional scores such as the short version of the Disabilities of the Arm, Shoulder and Hand score the Walch-Duplay score, and the Western Ontario Shoulder Instability Index (WOSI). RESULTS A total of 20 patients were included in each group. The mean ± SD age was 21 ± 1.8 years, and there were 33 men (82.5%) and 7 women (17.5%) in the total sample. Recurrence of instability was significantly decreased in the surgical treatment group compared with the nonoperative group (2 [10%] vs 14 [70%], respectively; P = .0001). Fewer patients in the surgical treatment group versus the nonoperative group had another episode of dislocation (0 vs 6 [30%], respectively), subluxation (2 [10%] vs 13 [65%], respectively; P = .003), or a positive apprehension test (1 [5%] vs 11 [58%], respectively; P = .0005). The Walch-Duplay score (88.4 vs 70.3 points; P = .046) and WOSI (11.5 vs 17.7 points; P = .035) were significantly better in the surgical group versus the nonoperative group after a 2-year follow-up. Level of sport was the same or better in 89% of the surgical treatment group vs 53% of the nonoperative treatment group (P = .012). No surgical complication was recorded. We did not find any significant difference in range of motion. CONCLUSION In patients with first-time shoulder dislocations, arthroscopic labral repair (Bankart procedure) reduced the risk of secondary shoulder dislocation and improved functional outcome versus nonoperative treatment after a 2-year follow-up. Surgical treatment after a first episode of shoulder dislocation could be offered as a primary treatment option in a younger population if these results are confirmed by larger studies with a longer follow-up.

Data from the Multicenter Orthopaedic Outcomes Network (MOON) Shoulder Instability Group. J Shoulder Elbow Surg 2021; 30:229-236.

Abstract
BACKGROUND The purpose of this study was to identify differences related to race in preoperative and intraoperative findings of patients undergoing operative treatment for shoulder instability. METHODS Data from the Multicenter Orthopaedic Outcomes Network (MOON) Shoulder Instability cohort were used. Of 1010 patients, 995 provided race and ethnicity information and were included in the analyses. Demographic characteristics, injury history, radiographic and intraoperative findings, and preoperative patient-reported instability, pain, and function were compared (1) between white and minority patients and (2) in a subgroup analysis between white patients and the 3 largest minority groups. The Distressed Communities Index (DCI) score was recorded for each patient's home ZIP code. Multiple logistic regressions were performed to determine whether models consisting of race/ethnicity, insurance carrier, and/or DCI score were predictive of bone and cartilage loss at the time of surgery. RESULTS Compared with white patients, a greater percentage of US minority patients had ≥2 dislocations (68.0% vs. 57.1%, P = .01), which corresponded with more frequent articular cartilage lesions (62.2% vs. 51.0%, P = .007) and increased frequencies of glenoid bone loss > 10% (16.2% vs. 8.7%, P = .03) and Hill-Sachs lesions (68.6% vs. 56.0%, P = .004). Specifically, when compared with white patients, African American and Asian patients showed significantly increased frequencies of glenoid bone loss > 10% (19.7% of African American patients, 18.4% of Asian patients, and 8.9% of white patients; P = .01) and Hill-Sachs lesions (65.6%, 71.7%, and 52.4%, respectively; P = .02). Race was an independent predictor of articular cartilage lesions (P = .04) and the presence of Hill-Sachs lesions (P = .01). A higher DCI score (P = .03) and race (P = .04) were both predictive of having glenoid bone loss > 10%. CONCLUSION We found that minority race was associated with increased number of preoperative dislocations and increased frequency of articular cartilage and Hill-Sachs lesions at the time of surgery, and both minority race and an increased DCI score were associated with glenoid bone loss > 10%. Further research is needed to understand the underlying reason for these differences and to optimize care for all patients with shoulder instability.

Abstract
BACKGROUND Although the glenoid labrum has an important role in shoulder stability, little is known about its composition, vascularity and innervation. The aims of this study were therefore to evaluate the histology, vascularity and innervation of the glenoid labrum. MATERIALS AND METHODS Ten glenoid labrum specimens (three male, two female: mean age 81.2 years, range 76-90 years) were detached at the glenoid neck. Following decalcification, sections were cut through the whole thickness of each specimen perpendicular to the glenoid labrum at 12 radii corresponding to a clock face superimposed on the glenoid fossa. Then they were stained using haematoxylin and eosin, a silver nitrate protocol or subjected to immunohistochemistry using anti-protein gene protein 9.5 to demonstrate neuronal processes. RESULTS The labrum was fibrocartilaginous, being more fibrous in its free margin. There was a variable distribution of blood vessels, being more vascular in its periphery, with many originating from the fibrous capsule and piercing the glenoid labrum. Immunohistochemistry revealed positive staining of nerve fibres within the glenoid labrum. CONCLUSION The glenoid labrum is fibrocartilaginous, being more fibrous in its periphery, and is vascularized, with the anterosuperior aspect having a rich blood supply. Free sensory nerve fibres were also present; no encapsulated mechanoreceptors were observed. The presence of sensory nerve fibres in the glenoid labrum could explain why tears induce pain. It is postulated that these sensory fibres could play a role in glenohumeral joint proprioception.

Abstract
PURPOSE The present study investigates the intra-articular findings and clinical outcomes after arthroscopic surgery in patients after age 40 with chronic anterior shoulder instability. METHODS Fifty patients older than 40 years who underwent arthroscopic stabilization for recurrent anterior shoulder dislocation were analyzed. RESULTS The mean age at the time of surgery was 44.8 years (range, 40-72 years), and the mean duration of follow-up was 45 months (range, 28-150 months). The mean visual analog scale score for pain with motion significantly improved from 4.1 preoperatively to 1.7 at the last follow-up (P < .001). The range of motion in the affected shoulder revealed limitations of 9.4° in forward flexion and 17.8° in external rotation compared with the unaffected shoulder. Both the Constant and Rowe scores significantly improved (P < .001 and P < .001, respectively). Recurrence, which includes dislocation and subluxation, occurred in 14% postoperatively. Anteroinferior labral lesion was seen in 92% of patients. Associated lesions included superior labrum anterior to posterior lesion (22%), midsubstance capsular tear (10%), and Hill-Sachs lesion (92%). Rotator cuff tears were found in 18%-partial-thickness tear in 10% and full-thickness tear, which was repaired with suture anchor, in 8%. Among the intra-articular lesions, there was no significant relation with recurrent instability or functional outcome as a single factor. CONCLUSIONS In patients with chronic anterior shoulder instability who were older than 40 years, the clinical results after arthroscopic surgery showed statistically significant improvement with good muscle strength recovery. The quality of labral lesion, size of the Hill-Sachs lesion, and glenoid defect showed positive correlation with the number of preoperative dislocation. The intra-articular pathologies were varied, however no single articular lesion had significant impact on the recurrence rate. LEVEL OF EVIDENCE Level IV, case series.

Abstract
Recurrent anterior shoulder instability remains a challenge to treat with arthroscopy, as the rate of postoperative instability remains high in certain patient populations. Indications for performing an "anatomic" arthroscopic reconstruction (isolated Bankart repair) are narrowing as surgeons identify risk factors for failure with this approach. In particular, the presence of certain bone loss patterns that occur with high numbers of instability events should prompt consideration for nonanatomic reconstruction, such as Latarjet or Hill-Sachs remplissage, to reduce the rate of postoperative recurrent instability.

Early return to baseline range of motion and strength after anterior shoulder instability surgery: a Multicenter Orthopaedic Outcomes Network (MOON) shoulder group cohort study. J Shoulder Elbow Surg 2018; 27:1235-1242. [PMID: 29576339 DOI: 10.1016/j.jse.2018.02.035] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/06/2017] [Revised: 01/31/2018] [Accepted: 02/01/2018] [Indexed: 02/01/2023]
Abstract
BACKGROUND Patients often return to higher-level activities and sports at 4 to 8 months after anterior shoulder stabilization procedures. It is unknown what percentage of patients have regained normal function at this time frame and what factors predict residual deficits, range of motion (ROM), and strength after anterior shoulder instability surgery. METHODS Ten participating sites throughout the United States enrolled patients in a prospective cohort study including primary, revision, arthroscopic, and open anterior stabilization procedures. Baseline demographic data and patient outcomes questionnaires were collected with initial physical examination, treatment, surgical findings, and surgical repair details. At the 6-month follow-up visit, ROM and strength measurements were collected and compared with preoperative measurements. RESULTS There were 348 patients identified who underwent surgical treatment for anterior shoulder instability. Of these, 259 patients (74.0%) returned to baseline, and 89 (26.0%) did not return to baseline shoulder ROM (≥20° loss of ROM) or strength. A higher Beighton score (P = .01) and number of dislocations (P < .01) were associated with failure to regain baseline ROM and strength at early follow-up. No surgical variables were found to influence return to baseline function, including open vs. arthroscopic surgery, primary vs. revision surgery, and number of suture anchors. CONCLUSIONS By 4 to 8 months postoperatively, 76% of patients return to baseline ROM, 98% return to baseline strength, and 74% return to both baseline ROM and strength. An increased number of dislocations and generalized joint laxity were associated with failure to return to baseline ROM and strength at early follow-up after anterior shoulder instability surgery.

Abstract
BACKGROUND Anterior shoulder dislocations in young patients are associated with high rates of recurrent instability. Although some surgeons advocate for surgical stabilization after a single dislocation event in this population, there is sparse research evaluating surgical treatment for first-time dislocators. METHODS Patients undergoing surgical stabilization for anterior shoulder instability were prospectively enrolled at multiple institutions from 2015-2017 and stratified by number of dislocations before surgery. Demographic data, preoperative patient-reported outcomes, imaging findings, surgical findings, and procedures performed were compared between groups. Analysis of variance, χ2, and multivariate logistic regression were used for statistical analysis. RESULTS The study included 172 patients (mean age, 25.3 years; 79.1% male patients) for analysis (58 patients with 1 dislocation, 69 with 2-5 dislocations, 45 with >5 dislocations). There were no intergroup differences in demographic characteristics, preoperative patient-reported outcomes, or physical examination findings. Preoperative imaging revealed increased glenoid bone loss in patients with multiple dislocation events (P = .043). Intraoperatively, recurrent dislocators were more likely to have bony Bankart lesions (odds ratio [OR], 3.26; P = .024) and biceps pathology (OR, 6.27; P = .013). First-time dislocators more frequently underwent arthroscopic Bankart repair and/or capsular plication (OR, 2.22; P = .016), while recurrent dislocators were more likely to undergo open Bristow-Latarjet procedures (OR, 2.80; P = .049) and surgical treatment for biceps pathology (OR, 5.03; P = .032). CONCLUSIONS First-time shoulder dislocators who undergo stabilization are more likely to undergo an arthroscopic procedure and less likely to have bone loss or biceps pathology compared with recurrent dislocators. Future studies are needed to ascertain long-term outcomes of surgical stabilization based on preoperative dislocation events.

Abstract
Background: The delayed management of patients with shoulder instability may increase the prevalence and severity of concomitant intra-articular shoulder injuries resulting from persistent subluxations and dislocations. Hypothesis: Patients with a longer delay from the initial dislocation event to undergoing magnetic resonance imaging (MRI) or magnetic resonance arthrography will demonstrate more subluxations or dislocations and a greater amount of intra-articular shoulder damage. Study Design: Cohort study; Level of evidence, 3. Methods: We performed a retrospective review of 89 patients from a single institution with clinically and radiographically confirmed primary traumatic anterior shoulder dislocations. Patients were divided into 2 groups: those undergoing MRI less than 6 months (n = 44; LT6) or greater than 6 months (n = 45; GT6) from the initial dislocation event. The MRI assessment included evaluation of soft tissue injuries, including the labrum, capsule, rotator cuff, and cartilage damage severity along with bone loss. Results: The delayed MRI group (GT6) demonstrated a greater degree of intra-articular abnormalities compared to the early MRI group (LT6). A greater percentage of superior labral anterior-posterior (SLAP) tears (58% vs 34%, respectively) and cartilage damage (73% vs 27%, respectively) was present in the GT6 group compared to the LT6 group. Cartilage damage was 18% mild, 7% moderate, and 2% severe for the LT6 group as compared to 38% mild, 31% moderate, and 4% severe for the GT6 group. Additionally, more recurrent shoulder dislocations were seen in the GT6 group (n = 6) compared to the LT6 group (n = 2). In the LT6 group, there were more rotator cuff tears (50% vs 24%, respectively) and capsular tears (25% vs 9%, respectively) than the GT6 group. There was no difference in anterior glenoid bone loss, glenoid version, or humeral head subluxation between the 2 groups. Conclusion: Patients who undergo MRI greater than 6 months from the time of primary or initial shoulder dislocation had significantly more recurrent shoulder instability events and demonstrated a greater incidence and severity of intra-articular abnormalities, including SLAP tears, posterior labral tears, and anterior glenoid cartilage damage.

Abstract
Purpose: Our purpose was to determine the relationship between number of preoperative shoulder dislocations and total dislocation time and the need to perform bone deficiency procedures at the time of primary anterior instability surgery. Our hypothesis was that need for bone deficiency procedures would increase with the total number and hours of dislocation. Materials and Methods: A retrospective review was performed of primary instability surgeries performed by a single surgeon. Patients with <25% glenoid bone loss were treated with an isolated arthroscopic Bankart repair. Those who also had an engaging Hill-Sachs lesion underwent arthroscopic Bankart repair with remplissage. Patients with >25% glenoid bone loss were treated with Latarjet reconstruction. Number of dislocations and total dislocation time were examined for their relationship with the treatment method. Results: Ten arthroscopic Bankart repairs, 13 arthroscopic Bankart plus remplissage procedures, and 9 Latarjet reconstructions were available for review. Total dislocations (P = 0.012) and total hours of dislocation (P = 0.019) increased from the Bankart, to the remplissage, to the Latarjet groups. Patients with a total dislocation time of 5 h or more were more likely to require a Latarjet reconstruction (P = 0.039). Patients with only 1 preoperative dislocation were treated with an isolated Bankart repair in 64% (7 of 11) of cases, whereas those with 2 or more dislocations required a bone loss procedure in 86% (18 of 21) of cases (P = 0.013). Conclusion: Increasing number of dislocations and total dislocation time are associated with the development of glenoid and humeral head bony lesions that alter surgical management of anterior shoulder instability. The necessity for the addition of a remplissage to an arthroscopic Bankart repair or the use of a Latarjet reconstruction increases with only 1 recurrent dislocation. Level of evidence: Level III, retrospective comparative study.

Abstract
Glenohumeral joint dislocation is common among younger, active patients. Anterior dislocation is the most common direction of instability following a traumatic event. Due to a high rate of recurrence following primary traumatic anterior shoulder dislocation, an evidence-based approach is necessary to determine the best treatment regime for a patient presenting with this problem. A history, physical examination, and radiographic imaging can help guide treatment recommendations by determining the extent of soft tissue damage following dislocation. Controversies in the treatment of the first-time dislocator include the length and position of immobilization following dislocation, and the role of initial surgical stabilization. This article outlines the treatment options for the first-time glenohumeral dislocator, with an emphasis on the available evidence in the literature. Where applicable, the criteria known as the Strength of Recommendation Taxonomy were used to summarize the strength of evidence available for recommendations.

Abstract
INTRODUCTION The recurrence rate after primary shoulder dislocation in young subjects with high functional demand is close to 75%. The present study assessed the interest of emergency arthroscopic stabilization in this specific population. MATERIAL AND METHODS A non-randomized prospective study included 31 athletes under 30 years of age with primary anterior shoulder dislocation. Fifteen were offered emergency stabilization; after informed consent, 14 were enrolled in the "emergency stabilization" group. This was compared to a group matched for age, sport and lesion, managed 1 year previously by "non-operative" treatment (n=17), divided into 2 subgroups: "immobilization" and "secondary stabilization". Continuous prospective assessment of recurrence, return to sport and function (QuickDASH, QDsport, Duplay and Rowe scores) enabled comparison between the 3 groups. RESULTS Mean follow-up was 19 months for the "emergency stabilization" group and 25 months for the "non-operative" group. There were no failures in the "emergency stabilization" group, compared to a 77% rate in the "non-operative" group with onset at a mean 7.5 months and a mean 2.6 episodes of recurrence. Seven (54%) of the failures of non-operative treatment required secondary stabilization. Ninety-three percent of the "emergency stabilization" group, 44% of the "immobilization" group and 71% of the "secondary stabilization" group resumed sport at least at their pre-dislocation level. Mean Quick DASH was 1.46 in the "emergency stabilization" group, versus 15.28 the "immobilization" group (P<0.05) and 16.96 in the "secondary stabilization" group. Mean Duplay and Rowe scores were respectively 92.9 and 95 in the "emergency stabilization" group, versus 59.44 and 61.1 in the "immobilization" group (P<0.05) and 85 and 93.57 in the "secondary stabilization" group. DISCUSSION Emergency arthroscopic stabilization limits recurrence (Kirkley et al.), with better functional results than for secondary stabilization, lesion "freshness" providing a more favorable environment for labral and ligamentary healing. These encouraging results need confirmation over longer follow-up.

Abstract
BACKGROUND Type IV superior labral anterior to posterior (SLAP) lesions, which are superior labral detachments associated with Bankart tears, are reported to occur in up to 25% of recurrent shoulder instability patients. However, the clinical implications of this finding are debatable. PURPOSE To determine whether there are any functional differences between anterior instability patients with and without type IV SLAP lesions at the time of presentation and at short-term follow-up after surgical intervention. STUDY DESIGN Cohort study; Level of evidence, 2. METHODS A prospective, multicenter database was established to follow the clinical evolution of patients with shoulder instability. Patients were diagnosed as having a type IV SLAP lesion at the time of arthroscopic Bankart surgery (SLAP+). These patients were compared with a group of patients who simply had a Bankart lesion (SLAP-). The 2 groups had their functional outcomes (Western Ontario Shoulder Instability Index [WOSI]; Disability of the Arm, Shoulder, and Hand [QuickDASH]; and Walch-Duplay) compared prior to surgery and 1 year postoperatively. RESULTS A total of 103 subjects were included in the study; of these, 56 (43 men, 13 women) completed 1-year follow-up. Twenty-three subjects had a type IV SLAP tear, and most had this repaired along with their Bankart lesion. At baseline, SLAP+ subjects had inferior QuickDASH scores compared with SLAP- subjects (37.8 vs 29.0) as well as poorer pain subscores on both the WOSI and QuickDASH. At 1-year follow-up, however, there were no significant differences in any of the outcome measures. CONCLUSION A type IV SLAP lesion can be expected in 22% of patients with recurrent shoulder instability. This finding implies that at baseline, the patient will have slightly worse functional scores related to pain. However, following surgical management of the labral pathology, these patients will have equivalent functional outcomes at short-term follow-up. CLINICAL RELEVANCE With surgical management of the superior and anteroinferior labrum, patients with type IV SLAP lesions will do as well as those with only Bankart tears. Thus, the presence of SLAP lesions should not alter the decision to provide surgical management and should not change the prognosis for a specific patient.

Abstract
BACKGROUND The macroscopic pathomorphology in recurrent shoulder instability has been described. However, less is known regarding the histopathologic details of the affected structures. This study evaluates different histopathologic stages of shoulder instability by assessing biopsy specimens of static stabilizers for possible correlations with clinical parameters. Our hypothesis was that clinical parameters of shoulder instability correlate with histopathologic findings. MATERIALS AND METHODS Passive shoulder stabilizers (labrum, anterior bundle of the inferior glenohumeral ligament) were biopsied during arthroscopic shoulder stabilization. Samples were submitted to immunohistochemistry, in situ hybridization, and blinded evaluation. Clinical data, comprising age (<30 years or ≥30 years), total number of dislocations (1, 2-3, or >3), and period since initial dislocation (<6 months, 6 months to 6 years, or >6 years), were tested for statistical correlation with the following histopathologic parameters: inflammation, lipomatous changes, vascular proliferation, tissue fragmentation, and cellularity. RESULTS Standardized biopsies were performed in 30 consecutive patients (4 women and 26 men; mean age, 32.6 years) with anterior shoulder instability. Microscopic evaluation showed only small variations in histologic changes among all samples. Only limited variations in cell density, matrix swelling, and collagen fiber disruptions were found. Immunohistochemical analysis showed a similar expression of decorin in all samples. Clinical parameters (age, total number of dislocations, and period since initial dislocation) were statistically independent from histopathologic parameters (inflammation, lipomatous changes, vascular proliferation, tissue fragmentation, and cellularity). No correlation was found in patients with 1 dislocation versus those with more than 1 dislocation. CONCLUSIONS In contrast to macroscopic findings among different grades of shoulder instability, this study detected no correlation between clinical items (age, total number of dislocations, and period since initial dislocation) and histopathologic parameters. These clinical items seem to be independent from the tissue status of static stabilizers of the shoulder.

Abstract
PURPOSE This study aimed to evaluate the relationship between the extent of the labral lesion and the frequency of glenohumeral dislocation in patients with shoulder instability. METHODS Ninety-three patients, who underwent surgical treatment at our clinic for chronic anterior shoulder dislocation, were selected and divided into 3 groups (group I: only Bankart lesion; group II: Bankart and SLAP lesions; group III: circumferential-labral lesion). The pre-operative frequency of dislocation, intraoperative findings, operation time, post-operative clinical score, and range of motion 2 years after surgery were analysed and compared among the 3 groups. RESULTS The time interval from the initial dislocation to operation was significantly shorter in group III than in groups I and II (P = 0.034 and P = 0.046, respectively). The median number of preoperative dislocations was also significantly less in group III than in groups I and II (P = 0.025 and P = 0.044, respectively). In all groups, the clinical scores (Constant, Rowe, and visual analogue scale) improved significantly post-operatively, and there were no significant differences in the scores between the different groups. All patients returned to work, and most patients returned to their preoperative sports activity levels. CONCLUSION The extent of the labral lesion is not always related to the number of dislocations; therefore, treatment should not be based on this. LEVEL OF EVIDENCE Retrospective comparative study, Level III.

Abstract
BACKGROUND Anterior shoulder stabilization surgery with the arthroscopic Bankart procedure can have a high recurrence rate in certain patients. Identifying these patients to modify outcomes has become a focal point of research. PURPOSE The Instability Shoulder Index Score (ISIS) was developed to predict the success of arthroscopic Bankart repair. Scores range from 0 to 10, with higher scores predicting a higher risk of recurrence after stabilization. The interobserver reliability of the score is not known. STUDY DESIGN Cohort study (diagnosis); Level of evidence, 2. METHODS This is a prospective multicenter (North America and Europe) study of patients suffering from shoulder instability and waiting for stabilization surgery. Five pairs of independent evaluators were asked to score patient instability severity with the ISIS. Patients also completed functional scores (Western Ontario Shoulder Instability Index [WOSI], Disabilities of the Arm, Shoulder and Hand-short version [QuickDASH], and Walch-Duplay test). Data on age, sex, number of dislocations, and type of surgery were collected. The test-retest method and intraclass correlation coefficient (ICC: >0.75 = good, >0.85 = very good, and >0.9 = excellent) were used for analysis. RESULTS A total of 114 patients with anterior shoulder instability were included, of whom 89 (78%) were men. The mean age was 28 years. The ISIS was very reliable, with an ICC of 0.933. The mean number of dislocations per patient was higher in patients who had an ISIS of ≥6 (25 vs 14; P = .05). Patients who underwent more complex arthroscopic procedures such as Hill-Sachs remplissage or open Latarjet had higher preoperative ISIS outcomes, with a mean score of 4.8 versus 3.4, respectively (P = .002). There was no correlation between the ISIS and the quality-of-life questionnaires, with Pearson correlations all >0.05 (WOSI = 0.39; QuickDASH = 0.97; Walch-Duplay = 0.08). CONCLUSION Our results show that the ISIS is reliable when used in a multicenter study with anterior traumatic instability populations. There was no correlation between the ISIS and the quality-of-life questionnaires, but surgical decisions reflected its increased use.
