Abstract
The Latarjet procedure is an established surgical treatment for recurrent glenohumeral joint instability with glenoid bone loss. Intraoperatively, the conjoint tendon and its attachement on the coracoid bone graft is routed through a split in subscapularis where the graft is fixed to and augments the anteroinferior glenoid. The objective of this in vitro study was to quantify the influence of glenohumeral joint position and conjoint tendon force on the lines of action and moment arms of subscapularis muscle sub-regions after Latarjet surgery. Eight fresh-frozen, entire upper extremities were mounted onto a testing apparatus, and a cable-pulley system was used to apply physiological muscle loading to the major shoulder muscles. The lines of action and moment arms of four subregions of subscapularis (superior, mid-superior, mid-inferior, and inferior) were quantified radiographically with the conjoint tendon unloaded and loaded while the shoulder was in (i) 0° abduction (ii) 90° abduction (iii) 90° abduction and full external rotation (ABER), and (iv) the apprehension position, defined as ABER with 30° horizontal extension. Conjoint tendon loading after Latarjet surgery significantly increased the inferior inclination of the lines of action of the mid-inferior and inferior subregions of subscapularis in the scapular plane in ABER and apprehension positions (p < 0.001), as well as decreased the horizontal flexion moment arm of the inferior subscapularis (p = 0.040). Increased subscapularis inferior inclination may ultimately increase inferior joint shear potential, while smaller horizontal flexion leverage may reduce joint flexion capacity. The findings have implications for Latarjet surgical planning and postoperative rehabilitation prescription.

Abstract
BACKGROUND The glenoid track concept for shoulder instability primarily describes the medial-lateral relationship between a Hill-Sachs lesion and the glenoid. However, the Hill-Sachs position in the craniocaudal dimension has not been thoroughly studied. HYPOTHESIS Hill-Sachs lesions with greater inferior extension are associated with increased risk of recurrent instability after primary arthroscopic Bankart repair. STUDY DESIGN Case-control study; Level of evidence, 3. METHODS The authors performed a retrospective analysis of patients with on-track Hill-Sachs lesions who underwent primary arthroscopic Bankart repair (without remplissage) between 2007 and 2019 and had a minimum 2-year follow-up. Recurrent instability was defined as recurrent dislocation or subluxation after the index procedure. The craniocaudal position of the Hill-Sachs lesion was measured against the midhumeral axis on sagittal magnetic resonance imaging (MRI) using either a Hill-Sachs bisecting line through the humeral head center (sagittal midpoint angle [SMA], a measure of Hill-Sachs craniocaudal position) or a line tangent to the inferior Hill-Sachs edge (lower-edge angle [LEA], a measure of Hill-Sachs caudal extension). Univariate and multivariate regression were used to determine the predictive value of both SMA and LEA for recurrent instability. RESULTS In total, 176 patients were included with a mean age of 20.6 years, mean follow-up of 5.9 years, and contact sport participation of 69.3%. Of these patients, 42 (23.9%) experienced recurrent instability (30 dislocations, 12 subluxations) at a mean time of 1.7 years after surgery. Recurrent instability was found to be significantly associated with LEA >90° (ie, Hill-Sachs lesions extending below the humeral head equator), with an OR of 3.29 (P = .022). SMA predicted recurrent instability to a lesser degree (OR, 2.22; P = .052). Post hoc evaluation demonstrated that LEA >90° predicted recurrent dislocations (subset of recurrent instability) with an OR of 4.80 (P = .003). LEA and SMA were found to be collinear with Hill-Sachs interval and distance to dislocation, suggesting that greater LEA and SMA proportionally reflect lesion severity in both the craniocaudal and medial-lateral dimensions. CONCLUSION Inferior extension of an otherwise on-track Hill-Sachs lesion is a highly predictive risk factor for recurrent instability after primary arthroscopic Bankart repair. Evaluation of Hill-Sachs extension below the humeral equator (inferior equatorial extension) on sagittal MRI is a clinically facile screening tool for higher-risk lesions with subcritical glenoid bone loss. This threshold for critical humeral bone loss may inform surgical stratification for procedures such as remplissage or other approaches for at-risk on-track lesions.

Abstract
BACKGROUND Military patients are known to suffer disproportionately high rates of glenohumeral instability as well as superior labrum anterior to posterior (SLAP) tears. Additionally, a concomitant SLAP tear is frequently observed in patients with anterior shoulder instability. Even though biceps tenodesis has been demonstrated to produce superior outcomes to SLAP repair in military patients with isolated SLAP lesions, no existing studies have reported on outcomes after simultaneous tenodesis and anterior labral repair in patients with co-existing abnormalities. PURPOSE To evaluate outcomes after simultaneous arthroscopic-assisted subpectoral biceps tenodesis and anterior labral repair in military patients younger than 40 years. We also sought to compare these outcomes with those after repair of an isolated anterior labral tear. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS This study is a retrospective analysis of all military patients younger than 40 years from a single base who underwent arthroscopic anterior glenohumeral stabilization with or without concomitant biceps tenodesis between January 2010 and December 2019. Patients with glenoid bone loss of >13.5% were not eligible for inclusion. Outcome measures including the visual analog scale (VAS) for pain, the Single Assessment Numeric Evaluation (SANE), the American Shoulder and Elbow Surgeons (ASES) shoulder score, the Rowe instability score, and range of motion were administered preoperatively and postoperatively, and scores were compared between groups. RESULTS A total of 82 patients met inclusion criteria for the study. All patients were active-duty service members at the time of surgery. The mean follow-up was 87.75 ± 27.05 months in the repair + tenodesis group and 94.07 ± 28.72 months in the isolated repair group (P = .3085). Patients who underwent repair + tenodesis had significantly worse preoperative VAS pain (6.85 ± 1.86 vs 5.02 ± 2.07, respectively; P < .001), ASES (51.78 ± 11.89 vs 62.43 ± 12.35, respectively; P = .0002), and Rowe (26.75 ± 7.81 vs 37.26 ± 14.91, respectively; P = .0002) scores than patients who underwent isolated repair. Both groups experienced significant improvements in outcome scores postoperatively (P < .0001 for all), and there were no statistically significant differences in postoperative outcome scores or range of motion between groups. There were no differences in the percentage of patients who achieved the minimal clinically important difference, substantial clinical benefit, and patient acceptable symptom state for the VAS pain, SANE, ASES, and Rowe scores between groups. Overall, 37 of the 40 (92.50%) patients in the repair + tenodesis group and 40 of the 42 (95.24%) patients in the isolated repair group returned to unrestricted active-duty military service (P = .6045). In addition, 38 (95.00%) patients in the repair + tenodesis group and 40 (95.24%) patients in the isolated repair group returned to preinjury levels of sporting activity (P = .9600). There were no significant differences in the number of failures, revision surgical procedures, or patients discharged from the military between groups (P = .9421, P = .9400, and P = .6045, respectively). CONCLUSION The findings of this study indicate that simultaneous biceps tenodesis and labral repair was a viable treatment option for the management of concomitant SLAP and anterior labral lesions in young, active military patients younger than 40 years.

Abstract
Background Recurrent anterior shoulder instability after arthroscopic Bankart repair presents a challenging clinical problem, with the primary stabilization procedure often portending the best chance for clinical success. Purpose To determine if capsuloligamentous laxity affects failure (recurrent dislocation, subluxation, and/or perceived instability symptoms) after arthroscopic Bankart repair in patients with near-track lesions (ie, those with smaller distance to dislocation [DTD]). Study Design Case-control study; Level of evidence, 3. Methods The authors retrospectively reviewed consecutive patients who underwent primary arthroscopic Bankart repair for recurrent anterior glenohumeral instability at a single institution between 2007 and 2019 and who had at least 2 years of follow-up data. Patients with glenoid bone loss >20%, off-track lesions, concomitant remplissage, or rotator cuff tear were excluded. Capsuloligamentous laxity, or hyperlaxity, was defined as external rotation >85° with the arm at the side and/or grade ≥2 in at least 2 planes with the shoulder at 90° of abduction. Near-track lesions were defined as those with a DTD <10 mm. Results Included were 173 patients (mean age, 20.5 years; mean DTD, 16.2 mm), of whom 16.8% sustained a recurrent dislocation and 6.4% had recurrent subluxations (defined as any subjective complaint of recurrent instability without frank dislocation), for an overall recurrent instability rate of 23.1%. The rate of revision stabilization was 15.6%. The mean time to follow-up was 7.4 years. Independent predictors of recurrent instability were younger age (P = .001), smaller DTD (P = .021), >1 preoperative instability episode (P < .001), and the presence of hyperlaxity during examination under anesthesia (P = .013). Among patients with near-track lesions, those with hyperlaxity had a recurrent instability rate almost double that of patients without hyperlaxity (odds ratio, 34.1; P = .04). The increased rate of failure and recurrent dislocation in the near-track hyperlaxity cohort remained elevated, even in patients with no bone loss. Conclusion Capsuloligamentous shoulder laxity was a significant independent risk factor for failure after primary arthroscopic Bankart repair without remplissage and was more predictive of failure in patients with versus without near-track lesions.

Abstract
Background Up to 20% of shoulders with anterior instability are associated with superior labrum anterior-posterior (SLAP) lesions, and they remain untreated after an open Latarjet procedure. SLAP lesions can be responsible for pain and feelings of instability in high-demand patients. Purpose/Hypothesis The aim of this study was to compare the early functional outcomes and return to sport rates in athletes after the Latarjet procedure with versus without associated SLAP lesions. It was hypothesized that untreated SLAP lesions would not influence clinical results. Study Design Cohort study; Level of evidence, 3. Methods Inclusion criteria were athletes with anterior shoulder instability treated with Latarjet procedure, a minimum follow-up of 1 year, and an available preoperative computed tomography arthrogram. We recorded patient characteristics; type of sport; bone loss; Rowe, Single Assessment Numeric Evaluation (SANE), and 11-item Disabilities of the Arm, Shoulder and Hand (QuickDASH) scores; 5-point pain and satisfaction scores; reported apprehension; and return to sport. Patients with and without a preoperative type 5 SLAP lesion on imaging were compared. Results Fifty patients were included (mean age, 22 ± 5 years [range, 16-36 years]; mean follow-up, 27 ± 9 months [range, 12-42 months]). Thirty-four patients practiced contact sports, including 20 rugby players. Twelve patients (24%) had a preoperative SLAP lesion. Groups with (+) and without (-) a SLAP lesion were comparable in terms of age, sex, number of instability episodes, type of sport, and glenoid and humeral bone loss. The SLAP+ group had significantly worse outcomes with a lower Rowe score (79 ± 23 vs 91 ± 15; P = .018) and painless rate (50% vs 77%; P = .04). There were no significant differences between the groups in SANE score (SLAP+ vs SLAP-: 80% vs 87%), QuickDASH score (8% vs 8%), return to sport (83% vs 91%), apprehension (79% vs 50%), and reported satisfaction. There was 1 episode of postoperative subluxation in each group. Conclusion Patients who underwent an open Latarjet procedure with an associated SLAP tear more frequently reported postoperative pain than those without a SLAP lesion. Patients with untreated SLAP tears had significantly lower Rowe scores, although SANE score and return to sport were not significantly different between the groups.

Abstract
PURPOSE To report on intraoperative and short-term postoperative adverse events after open Latarjet procedure in patients with recurrent anterior shoulder instability. These complications were classified into different grades of severity based on the treatment required and the learning curve of the procedure. METHODS Ninety-six patients (102 shoulders) underwent open Latarjet procedure for recurrent post-traumatic anterior glenohumeral instability between 2012 and 2020. The minimum duration of patients' follow-up was 6 months. Adverse events were classified into 3 classes based on the severity and subsequent treatment. The complications in the first 50% of all cases were compared with the latter 50% to evaluate the role of learning curve on the complication rates. RESULTS The mean follow-up was 7.2 ± 2.8 months. The patients' mean age was 26.7 ± 8.9 years and consisted of 83 (86.4%) male and 13 (13.6%) female patients. The total adverse events rate was 18.6%. Adverse events requiring no additional treatment (class 1) occurred in 6 cases (5.8%) including fibrous union (3.9%) and asymptomatic resorption of the graft (1.9%). Adverse events requiring additional or extended nonoperative management (class 2) occurred in 8 cases (7.8%), including coracoid fracture (2.9%), musculocutaneous nerve palsy (1.9%), axillary nerve palsy (0.9%), suprascapular nerve palsy (0.9%), and stiffness (0.9%). All the nerve palsies recovered without long-term sequelae. Adverse events requiring secondary operative procedures (class 3) occurred in 5 cases (4.9%), including symptomatic hardware (1.9%), medial healing of the graft (0.9%), screw loosening (0.9%), and deep infection (0.9%). The rate of adverse events in revision cases was higher than primary cases in 11.7% and 6.8%, respectively (P = .119). The complication rate was significantly higher in the first half of the surgeons' practice (14.7%) than in the second half (3.9%) (P ≤ .05). CONCLUSIONS The overall complication rate reported in this open Latarjet series is 18.6%; however, the rate of class 3 adverse events that required additional surgery or long-term medical treatment was only 4.9%. Revision cases had a higher rate of complications than primary cases, and the learning curve has had a significant impact on the rate of adverse events.

Abstract
PURPOSE The purpose of this study is to compare the open Latarjet procedure versus the all-arthroscopic autologous tricortical iliac crest bone grafting (AICBG) technique for recurrent anterior-inferior glenohumeral instability with glenoid bone loss. METHODS All open Latarjet and AICBG procedures for recurrent anterior-inferior shoulder instability with glenoid bone loss performed at two institutions between September 2015 and April 2019 were retrospectively analyzed. Inclusion criteria were a traumatic etiology, a glenoid surface deficiency >13.5%, and a minimum follow-up (FU) of 18 months. Primary outcomes included the subjective shoulder value, the Western Ontario Shoulder Instability (WOSI), Rowe scores including subdomains, and the four subdomains of the Constant score (pain, activities of daily living, internal rotation, external rotation). Secondary outcomes were subjective shoulder instability, EQ-5D-3 L, pain level on the VAS, level of overall satisfaction, operative time, return-to-work rate, and return-to-sports rate. RESULTS Forty-three patients were available for final analysis (Latarjet: n = 21; AICBG: n = 22) at an average FU of 34.9 months (range, 22-66 months). Both techniques provided good outcomes and improved stability. The Rowe score, Rowe-range of motion, and CS-internal rotation (p = 0.008, p<0.001, p = 0.001) were slightly better in the AICBG group. Furthermore, the WOSI physical symptoms subdomain was significantly better (p = 0.04) in the AICBG group, while its total score did not reach statistical significance (p = 0.07). There was no statistically significant difference in the secondary outcomes besides operative time, which was significantly shorter in the Latarjet procedure group (p = 0.04). Overall complication rate was similar in both groups (Latarjet: 9.5% (n = 2), AICBG: 9.1% (n = 2)). CONCLUSION Open Latarjet and AICBG procedures provide comparable clinical outcomes except for significantly better Rowe score, Rowe-range of motion, WOSI physical symptoms subdomain, and internal rotation capacity in the AICBG group. However, these results should be carefully interpreted in the context of known minimal clinically important differences of these scores.

Abstract
Bone graft resorption following the Latarjet procedure has received considerable concern. Current methods quantifying bone graft resorption rely on two-dimensional (2D) CT-scans or three-dimensional (3D) techniques, which do not represent the whole graft volume/resorption (i.e., 2D assessment) or expose patients to additional radiation (i.e., 3D assessment) as this technique relies on early postoperative CT-scans. The aim of the present study was to develop and validate a patient-specific, CT-morphometric technique combining image registration with 3D CT-reconstruction to quantify bone graft resorption following the Latarjet procedure for recurrent anterior shoulder instability. Pre-operative and final follow-up CT-scans were segmented to digitally reconstruct 3D scapula geometries. A virtual Latarjet procedure was then conducted to model the timepoint-0 graft volume, which was compared with the final follow-up graft volume. Graft resorption at final follow-up was highly correlated to the 2D gold standard-technique by Zhu (Kendall tau coefficient = 0.73; p < 0.001). The new technique was also found to have excellent inter- and intra-rater reliability (ICC values, 0.931 and 0.991; both p < 0.001). The main finding of this study is that the technique presented is a valid and reliable method that provides the advantage of 3D-assessment of graft resorption at long-term follow-up without the need of an early postoperative CT-scan.

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

Abstract
INTRODUCTION The classical shoulder tests for instability of the glenohumeral joint are the load and shift and drawer tests. Here, the humeral head is gripped between fingers and thumb to assess translation. This can be challenging to perform accurately in obese individuals and muscular athletes. TECHNICAL TIP The shoulder and upper arm is utilized as a Class 3 lever. By fixing the patient's elbow (fulcrum) and applying translational force on the humerus (force), the instability at the glenohumeral joint (load) can be accurately judged. The mechanical advantage of a Class 3 lever is utilized to generate maximal displacement at the glenohumeral joint by applying minimal translational force at the humerus. The translation can be graded with the modified Hawkins scale. CONCLUSION The shoulder lever test obviates the need to grip the humeral head in obese and well-built individuals to accurately judge the translation at the glenohumeral joint, improving the clinical yield.

Abstract
Shoulder instability is a relatively common injury especially in the young athletic population and its surgical management continues to remain a controversial topic in sports medicine orthopedics. Anterior instability is the most common type encountered and is estimated to have an incidence rate of 0.08 per 1000 person-years in the general population; however, this figure is likely higher in the young athletic population. While in recent practice, arthroscopic surgery has become the new gold standard for management, reported failure rates as high as 26% and high recurrence rates in specific subpopulations such as young men in high collision sports have led to the consideration of alternative open procedures such as open Bankart repair, Latarjet, capsular shift, and glenoid bone grafting. These procedures may be preferred in specific patient subgroups such as young athletes involved in contact sports and those with Hill-Sachs defects and multidirectional instability, with postoperative recurrence rates of instability as low as 10%. The purpose of this review is to provide an overview of different open surgical techniques in the management of shoulder instability and summarize patient outcomes including recurrence rates for shoulder instability, return to sport, range of motion (ROM), muscle strength, and complications either individually by procedure or in comparison with other techniques, with special focus on their impact in the athletic population.

Abstract
Background: Open Bankart repair provides surgeons and patients with an alternative
solution for managing recurrent instability in young athletes with or
without minimal bone loss. Despite many studies that have reported low
recurrence rates and good functional outcomes after open Bankart repair, we
have limited knowledge about the return to sport and work for high-demand
populations. Purpose: To assess the return to sport and work for high-demand populations after open
Bankart repair for recurrent anterior shoulder instability, outcomes of open
Bankart repair with regard to recurrence, and development of osteoarthritic
(OA) changes. Study Design: Systematic review; Level of evidence, 4. Methods: We searched PubMed, EMBASE, Cochrane Library, Scopus, and Google Scholar
databases using keywords as well as Medical Subject Headings terms and
Emtree using “(Open Bankart OR Bankart surgery) (NOT arthroscopy NOT
revision)” for English-language studies. We conducted a systematic review in
accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews
and Meta-Analyses) guidelines. Results: In total, 11 articles (10 with level 4 and 1 with level 3 evidence) including
563 patients (566 shoulders) were identified. The majority of patients were
male (82%), the average age at the time of surgery was 27.4 years, and the
mean follow-up was 11.5 years (range, 2.5-29 years). The most common
functional score used was the Rowe score (95%) for the reported outcome
measures, which showed good to excellent results (mean, 88.5 points). The
overall recurrent instability rate, including dislocation and subluxation as
a postoperative complication, was 8.5%. A total of 87% of patients were able
to return to sport and work postoperatively. Overall, OA changes were
reported in 33% of the patients, and the overall revision rate was 1%. Conclusion: Open Bankart repair exhibited favorable results, with a low postoperative
instability rate. It is a reliable surgical procedure that allows
high-demand patients to return to sport and work.

Abstract
BACKGROUND Recent studies have demonstrated equivalent short-term results when comparing arthroscopic versus open anterior shoulder stabilization. However, none have evaluated the long-term clinical outcomes of patients after arthroscopic or open anterior shoulder stabilization, with inclusion of an assessment of preoperative glenoid tracking. PURPOSE To compare long-term clinical outcomes of patients with recurrent anterior shoulder instability randomized to open and arthroscopic stabilization groups. Additionally, preoperative magnetic resonance imaging (MRI) studies were used to assess whether the shoulders were "on-track" or "off-track" to ascertain a prediction of increased failure risk. STUDY DESIGN Randomized controlled trial; Level of evidence, 1. METHODS A consecutive series of 64 patients with recurrent anterior shoulder instability were randomized to receive either arthroscopic or open stabilization by a single surgeon. Follow-up assessments were performed at minimum 15-year follow-up using established postoperative evaluations. Clinical failure was defined as any recurrent dislocation postoperatively or subjective instability. Preoperative MRI scans were obtained to calculate the glenoid track and designate shoulders as on-track or off-track. These results were then correlated with the patients' clinical results at their latest follow-up. RESULTS Of 64 patients, 60 (28 arthroscopic and 32 open) were contacted or examined for follow-up (range, 15-17 years). The mean age at the time of surgery was 25 years (range, 19-42 years), while the mean age at the time of this assessment was 40 years (range, 34-57 years). The rates of arthroscopic and open long-term failure were 14.3% (4/28) and 12.5% (4/32), respectively. There were no differences in subjective shoulder outcome scores between the treatment groups. Of the 56 shoulders, with available MRI studies, 8 (14.3%) were determined to be off-track. Of these 8 shoulders, there were 2 surgical failures (25.0%; 1 treated arthroscopically, 1 treated open). In the on-track group, 6 of 48 had failed surgery (12.5%; 3 open, 3 arthroscopic [P = .280]). CONCLUSION Long-term clinical outcomes were comparable at 15 years postoperatively between the arthroscopic and open stabilization groups. The presence of an off-track lesion may be associated with a higher rate of recurrent instability in both cohorts at long-term follow-up; however, this study was underpowered to verify this situation.

Abstract
BACKGROUND This study aimed to determine the prevalence of the Buford complex and to investigate its association with labral pathologies (superior labrum anterior-posterior [SLAP] lesion and anterior, posterior, or multidirectional instability) using a very large patient database. Furthermore, the prevalence of the Buford complex in patients without any labral pathology was also determined. METHODS A total of 3129 consecutive shoulder arthroscopy procedures were retrospectively evaluated for the presence of the Buford complex and coexisting labral pathologies. The relationships between the Buford complex and SLAP lesions, as well as instability, were evaluated statistically. RESULTS The Buford complex was observed in 83 shoulders (2.65%). SLAP lesions were significantly more frequent in patients with the Buford complex than in those without it (81.9% vs. 33.1%, P < .001) Shoulders with the Buford complex presented a lower frequency of anterior instability (10.8% vs. 19.3%, P = .052) and a higher frequency of posterior instability (1.2% vs. 0.9%, P = .789). The prevalence of the Buford complex in patients with and without labral pathologies was 4.6% and 0.3%, respectively (P < .001). CONCLUSIONS This study, to our knowledge, includes the largest cohort in the literature reporting the prevalence of the Buford complex (2.65%). In the 1461 patients without labral tears or multidirectional instability, the prevalence of the Buford complex was 0.3%. This result suggests that the real prevalence of the Buford complex might be lower than that reported previously. In addition to the aforementioned conclusions, the identification of the Buford complex should prompt a thorough evaluation for concomitant SLAP lesions.

Abstract
OBJECTIVE The aim of this study was to evaluate glenohumeral morphologic differences and their correlation between glenohumeral instability and rotator cuff pathology. METHODS Two-hundred radiographs and 100 MRI scans of 100 patients in whom the diagnosis of Anterior Shoulder Instability (Anl) or Rotator Cuff Tear (RCT) was arthroscopically verified were retrospectively identified and included in the study. All the patients were categorized into two groups: 50 patients with Anl (23 female, 28 male; mean age = 29 ± 7.4) and 50 patients with RCT (28 female, 22 male). Two separate control groups were then formed, one of which included contralateral shoulders of patients in the AnI group, and the other consisted of contralateral shoulders of patients in the RCT group. The x-ray and MRI scans were examined by an orthopedic surgeon and a radiologist. The Acromial Index (AI) and the Critical Shoulder Angle (CSA) were measured on true anteroposterior shoulder radiographs; Glenoid Inclination (GI), Glenoid Version (GV), and Acromion Angulation (AA) were measured on MRI. RESULTS In the AnI group, the measurements were as followed: AI, 0.66 ± 0.03; CSA, 33 ° ± 2.85; GI, 3.4° ± 6.2; GV, 4.1 ± 4.3; and AA, 12.9 ± 8.3. In the RCT group, AI 0.71 ± 0.04; CSA, 36° ± 2.69; GI, 9.1 ± 5; GV, 6.7 ° ± 5.7; and AA, 14.3° ± 8.7. A moderate correlation was found between CSA and GI (r = 0.41, P = 0.001) and between AI and GI (r = 0.42, P = 0.014). A weak correlation was found between AI and GI in the AnI group (r = 0.22, P = 0.001). The inter- and intra-observer intraclass correlation coefficients were respectively 0.81 and 0.84 for AI, 0.88 and 0.92 for CSA, 0.72 and 0.76 for GI, 0.69 and 0.73 for GV, and 0.72 and 0.77 for AA. CONCLUSION The results of this study have shown that lower AI, GI, and antevert GV may be associated with AnI. Investigating CSA, AI, and GV could be useful for diagnostic evaluation of patients with AnI. LEVEL OF EVIDENCE Level III, Diagnostic Study.

Abstract
Anterior shoulder instability following traumatic dislocation in young adults is a common complication. The Latarjet procedure is the most widely used technique for treating this instability. It is based on coracoid abutment repair of the anterior edge of the glenoid. However, joint exposure during this surgical technique is often limited and makes it difficult to position the abutment. The purpose of this study was to evaluate the result of coracoid abutment procedure on functional outcome in the short and medium term. We assessed the positioning of the coracoid abutment on standard postoperative X-rays and the functional outcome according to Duplay score as well as the satisfaction rate in 70 patients. The average age of patients was 25 and a half years, the sex-ratio was nine, and the mean follow-up period was 6.5 years. Radiological examination showed that coracoid abutment was in subequatorial or non-flush position with respect to the anterior glenoid rim (too internal or protruding in intra-articular position) in 20% of cases. This group showed a drop in mean stability score by 7.68 points, in pain by 10.04 points and in Duplay's overall score by 13.3 points as well as a significant increase in the level of glenohumeral arthrosis. This study highlights that coracoid abutment in subequatorial or non-flush position has deleterious effect on the functional outcome of the Latarjet procedure.

Abstract
Background: Arthroscopic Bankart repair (ABR) and the Latarjet procedure are surgical techniques commonly used to treat anterior shoulder instability. There is no consensus among shoulder surgeons regarding the indications for choosing one over the other. Purpose: To compare the results of the Latarjet procedure with those of ABR for the treatment of anterior shoulder instability. Study Design: Cohort study; Level of evidence, 3. Methods: Data on all patients who were treated surgically for recurrent anterior shoulder instability between 2006 and 2011 were retrospectively collected at 4 medical centers. The minimum follow-up was 5 years. Data were retrieved from medical charts, and patients were interviewed to assess their level of satisfaction (range, 0-100), functional outcomes (using the American Shoulder and Elbow Surgeons shoulder score; the Subjective Shoulder Value; and the Disabilities of the Arm, Shoulder and Hand score), and quality of life (using the 12-Item Short Form Health Survey [SF-12]). Information on return to sports activities and postoperative level of activity compared with that of the preinjury state, complications, reoperations, and recurrent instability were recorded and evaluated. Results: A total of 242 patients were included. The Latarjet procedure was performed in 27 shoulders, and ABR was performed in 215 shoulders. Patients in the ABR group had significantly higher rates of redislocation (18.5%; P = .05) and subluxation (21.4%; P = .43) but a lower rate of self-reported apprehension (43.0%; P = .05) compared with patients in the Latarjet group (3.7%, 14.8%, and 63.0%, respectively). There were 5 patients in the ABR group who underwent reoperation with the Latarjet procedure because of recurrent instability. The functional scores in the Latarjet group were better than those in the ABR group. The SF-12 physical score was significantly better in the Latarjet group than in the ABR group (98.1 vs 93.9, respectively; P = .01). Patient satisfaction and subjective scores were similar in both groups. Conclusion: These results support recently published data on the Latarjet procedure that showed its superiority over ABR in midterm stability (dislocations or subluxations). The contribution of self-reported apprehension to the broad definition of stability is not clear, and apprehension rates were not correlated with satisfaction scores or the recurrence of dislocation or subluxation.

Abstract
INTRODUCTION Recurrent anterior glenohumeral instability has been studied in the young population and limited evidence is available for adolescent patients. Our study is a retrospective review of patients aged <17 years who underwent open Latarjet procedure. METHODS Forty-five patients were available for review. Clinical outcomes were assessed by range of movements, stability, Walch-Duplay score (WDS), Rowe score (RS), Constant-Murley score (CMS), Subjective Shoulder Value (SSV), and return to sport. Radiographs were reviewed for osteoarthritis and complications. RESULTS The median age of patients was 15.7 years (13-17), and 56% had hyperlaxity. The median follow-up time was 6.6 years (3-26). The median postoperative movements showed recovered elevation (175°), external rotation (60°), and internal rotation (T9 level). Seventy-five percent of patients returned to the same level of sport, and 98% were satisfied. Clinical outcomes showed WDS, RS, and CMS scores of 85, 95, and 84 points, respectively, and an SSV of 95%. Twenty percent of patients described mild postoperative pain, and 1 had persistent stiffness. Other complications included 24% subjective apprehension, 4% redislocation, 4% wound problems, and 2% infection. Nine percent of cases had postoperative arthritis. The overall reoperation rate was 11%: 1 open washout for infection and 4 arthroscopic screw removal due to persistent pain. We found that hyperlaxity, female sex, and large or deep Hill-Sachs lesions were frequently associated with persistent apprehension at the last follow-up. CONCLUSIONS The open Latarjet procedure provides a low rate of recurrent instability with acceptable complication rates in the long term for skeletally immature patients. It is an effective, safe treatment option without any significant glenoid growth disturbance.

Abstract
Glenohumeral instability is a common pathology of the shoulder joint, especially among young athletes. Despite advancements in technology and the widespread use of diagnostic imaging, a careful history and physical examination still remain the cornerstone of diagnosing patients with shoulder instability. Due to the involvement of many static and dynamic stabilizers, proficient physical examination can be challenging. With a systematic approach to clinical evaluation, the clinician can recognize characteristic patterns of relevant signs and symptoms and make an accurate diagnosis.

Abstract
BACKGROUND The open Latarjet procedure is a standard surgical treatment option for anterior shoulder instability in patients with a high risk of failure following soft tissue stabilization. The arthroscopic technique has potential advantages of minimal invasiveness, reduced postoperative stiffness, and faster rehabilitation but is regarded as technically challenging with concern over surgical risk during the learning curve. The aim of this study was to undertake a multisurgeon, large-volume learning curve analysis of the arthroscopic Latarjet procedure using continuous learning curve analysis. METHODS Individual patient data from 12 surgeons across 5 countries were retrospectively reviewed. A total of 573 patients undergoing the arthroscopic Latarjet procedure were included. Outcome measures of learning were collected, including operative time, computed tomography (CT) bone-block positioning, complications, and patient-reported outcome measures (PROMs). A segmented linear regression modeling technique was used for learning curve analysis. RESULTS High-volume surgeons converged to an operative time steady state after 30-50 cases. Surgeons completing fewer procedures demonstrated a constant reduction in operative time without reaching a plateau. Low-volume surgeons completing fewer than 14 operations did not demonstrate a reduction in operative time. Accuracy of bone-block positioning on postoperative CT demonstrated constant improvement without reaching a plateau after 53 cases. There was no change in PROMs or complications with increased operative volume. CONCLUSION Specialist shoulder surgeons require 30-50 arthroscopic Latarjet procedures to attain steady-state operative efficiency, during which there is improvement in bone-block positioning. Only surgeons expecting to undertake the arthroscopic Latarjet in high volume should consider adopting this procedure.

Abstract
BACKGROUND Some studies have advocated the use of suture-button fixation during the Latarjet procedure to reduce complications associated with screw fixation. However, the sample size of these studies is relatively small, and their follow-up period is short. PURPOSE To investigate the efficacy of the suture-button Latarjet procedure with at least 3 years of follow-up and remodeling of the coracoid graft. STUDY DESIGN Case series; Level of evidence, 4. METHODS A total of 152 patients who underwent the suture-button Latarjet procedure between February 2013 and February 2016 were selected, and 128 patients who met the inclusion criteria were enrolled in this study. Preoperative and postoperative clinical results were assessed. The position and healing condition of the coracoid graft and arthropathy of the glenoid and humeral head were also assessed using radiography and 3-dimensional computed tomography (CT). RESULTS The mean follow-up time was 40.3 ± 5.8 months. There were 102 patients included in this study. The mean visual analog scale score for pain during motion, the American Shoulder and Elbow Surgeons score, the Rowe score, and the Walch-Duplay score were improved considerably. A total of 100 grafts achieved bone union. The overall absorption rate was 12.6% ± 4.3%. Graft absorption mostly occurred on the edge and outside the "best-fit" circle of the glenoid. A vertical position was achieved in 98 grafts (96% of all cases) immediately postoperatively, with the mean graft midline center at the 4 o'clock position. In the axial view, CT showed that 89 grafts were flush to the glenoid, whereas 2 and 11 grafts were fixed medially and laterally, respectively. In all cases, the bone graft and glenoid tended to extend toward each other to form concentric circles during the remodeling process. During follow-up observations, the height of the 11 grafts that were positioned laterally (ie, above the glenoid level) exhibited a wave-curved change. No arthropathy was observed in any patient. CONCLUSION Patient outcomes were satisfactory after the modified arthroscopic suture-button Latarjet technique. Graft absorption mostly occurred on the edge and outside the "best-fit" circle of the glenoid. The graft exhibited the phenomenon of ectatic growing when it fused with the glenoid and finally remodeled to a new concentric circle with the humeral head analogous to the original glenoid. Grafts positioned laterally did not cause arthropathy of the joints within the period of the study.

Abstract
BACKGROUND The Latarjet procedure is often used to treat shoulder instability in younger patients. Little is reported on the outcomes of this procedure in older (≥40 years) populations. The purpose of this study was to evaluate the clinical and radiographic outcomes of patients aged 40 years or older with recurrent anterior shoulder instability who underwent open Latarjet stabilization. METHODS A total of 168 patients aged 40 years or older were treated surgically for recurrent anterior shoulder instability with an open Latarjet procedure between 1988 and 2014. Bankart lesions or anteroinferior glenoid fractures were confirmed preoperatively with a computed tomography arthrogram. Outcomes were assessed with preoperative and postoperative physical examinations, clinical outcome scoring, and radiographic examinations. RESULTS Ninety-nine patients with complete data were available with a mean follow-up period of 13 years (range, 3-23 years). At the time of final follow-up, 94% of patients did not have recurrence of instability. Of the patients, 90% were satisfied or very satisfied with their outcomes and 54% returned to their preinjury level of activity. The overall complication rate was 21% (the most common complications being subjective apprehension [9%] and recurrent instability [6%]), with 9% of patients requiring reoperation. A full-thickness rotator cuff requiring repair was identified in 22% of patients. CONCLUSIONS The Latarjet procedure is an effective treatment option for older patients (aged ≥ 40 years) with recurrent anterior shoulder instability in the setting of an anteroinferior capsulolabral and/or bony injury.

Abstract
BACKGROUND Glenohumeral instability is a rare indication for primary reverse total shoulder arthroplasty (RTSA), accounting for fewer than 1% of the indications in the literature. The aim of this study was to analyze the clinical and radiographic outcomes of RTSA for recurrent instability after failed operative repair or instability associated with major bone loss in elderly patients. METHODS A retrospective matched case-control study was performed. We compared 11 shoulders treated with RTSA for instability (cases) with 22 matched shoulders treated with RTSA for rotator cuff insufficiency (controls). Clinical and radiographic outcomes were compared. RESULTS The median follow-up period was 74 months (interquartile range [IQR], 18 months; range, 22-171 months) in cases and 70 months (IQR, 13 months; range, 23-172 months) in controls. The median age was 74 years (IQR, 18 years) in the case group and 70 years (IQR, 13 years) in the control group. No significant differences were found between the 2 groups in satisfaction scores, preoperative and postoperative absolute and relative Constant scores, and complication rates. Active range of motion tended to be superior in the controls for mean flexion (130° vs. 110°, P = .15), abduction (143° vs. 100°, P = .16), and external rotation (28° vs. 20°, P = .86) without the differences reaching statistical significance, possibly because of the small sample size. Postoperative dislocation was not recorded in cases or controls, but subjective insecurity regarding stability was reported once in each group. CONCLUSION RTSA seems to represent a valuable treatment option for glenohumeral instability in an elderly population with large bone loss or as a salvage procedure after failed operative glenohumeral stabilization. Postoperative instability was not observed in the case and control groups.

Abstract
To listen to the podcast associated with this article, please select one of the following: iTunes, Google Play, or direct download. OBJECTIVE. The purpose of this study is to determine the most accurate imaging techniques to measure glenoid bone loss in anterior glenohumeral instability through a systematic review of existing literature. MATERIALS AND METHODS. We performed a comprehensive literature search of five databases for original research measuring glenoid bone loss at radiography, CT, or MRI, using prospective or retrospective cohort, case-control, or cadaveric study designs up to January 2018. The Quality Assessment of Diagnostic Accuracy Studies-2 tool aided qualitative assessment of the methods. Data extraction included results, index test interobserver agreement, and accuracy analysis. RESULTS. Twenty-seven studies (evaluating 1425 shoulders) met inclusion criteria after full-text review by two independent readers. Glenoid bone loss was assessed, comparing several index tests to nonimaging (n = 18 studies) and imaging (n = 11) reference standards. Compared with arthroscopic or cadaveric measurements, 2D CT was accurate in six of seven studies (86%), 3D CT was accurate in eight of 10 studies (80%), 2D MRI was accurate in five of seven studies (71%), 3D MRI was accurate in four of four studies (100%), and radiographs were accurate in zero of four studies (0%). Best-fit circle methods (glenoid width or Pico surface area) were the most common and both were accurate (86-90% and 75-100%, respectively) using CT and MRI. Studies had good external validity (78%). Most risk for bias arose from patient selection and reference standards. Only two studies reported sensitivity and specificity, both comparing CT to arthroscopy using different bone loss thresholds (20% and 25%). CONCLUSION. CT and MRI (2D or 3D) accurately measure glenoid bone loss in anterior shoulder instability, but radiographs do not. Best-fit circle measurement techniques are reliable and accurate. Current literature about glenoid bone loss is heterogeneous, and future studies should focus on diagnosis of clinically relevant glenoid bone loss.

Abstract
HYPOTHESIS We hypothesized that a new method considering the humeral head would distinguish rotator cuff tears (RCTs) and osteoarthritis (OA) better than the critical shoulder angle (CSA). METHODS A total of 1011 patients were tested in this study and divided into 4 groups: those with RCTs (n = 493), those with OA (n = 73), those with anterior instability (n = 361), and those with adhesive capsulitis (n = 84). The CSA and new radiologic parameters including the humeral head were measured in the true anterior-to-posterior view: the Y angle connecting the lower end of the glenoid (LG), the center of the humeral head (CH), and the upper end of the glenoid (UG); the G angle connecting UG, CH, and the lateral tip of the acromion; the YG angle connecting LG, CH, and the lateral tip of the acromion; and the R angle connecting UG, LG, and CH. RESULTS The CSA and G angle were the largest in the RCT group (34.2° and 70.4°, respectively; P < .001) and the smallest in the OA group (29.8° and 61.7°, respectively; P < .001). The Y angle was the largest in the OA group (82.8°, P < .001). The R angle in the RCT group (52.9°) was significantly larger than that in the OA group, which was the smallest among the groups (48.0°; P < .001). The CSA was correlated with the G and YG angles in the RCT group, whereas the CSA was correlated with the Y, G, and R angles in the OA group (P < .05). The CSA showed the highest correlation with the size of RCTs (correlation coefficient = 0.138). CONCLUSION The Y, G, and R angles reflected the lesions of RCTs or OA. The CSA showed good correlations with the new radiologic parameters, and it had the highest correlation coefficient with the size of RCTs.

Abstract
BACKGROUND Anterior and posterior shoulder instabilities are entirely different entities. The presenting complaints and symptoms vastly differ between patients with these 2 conditions, and a clear understanding of these differences can help guide effective treatment. PURPOSE To compare a matched cohort of patients with anterior and posterior instability to clearly outline the differences in the initial presenting history and overall outcomes after arthroscopic stabilization. STUDY DESIGN Cohort study; Level of evidence, 2. METHODS Consecutive patients with either anterior or posterior glenohumeral instability were prospectively enrolled; patients were excluded if they had more than 10% anterior or posterior glenoid bone loss, multidirectional instability, neurologic injury, or prior surgery. Patients were assigned to anterior or posterior shoulder instability groups based on the history and clinical examination documenting the primary direction of instability, with imaging findings to confirm a labral tear associated with the specific direction of instability. Preoperative demographic data, injury history, and overall clinical outcome scores (American Shoulder and Elbow Surgeons [ASES], Single Assessment Numeric Evaluation [SANE], and Western Ontario Shoulder Index [WOSI]) were assessed and compared statistically between the 2 cohorts. Patients were indicated for surgery if they elected to proceed with surgical management or did not respond to a course of nonoperative management. RESULTS The study included 103 patients who underwent anterior stabilization (mean age, 23.5 years; range, 18-36 years) and 97 patients who underwent posterior stabilization (mean age, 24.5 years; range, 18-36 years). The mean follow-up was 39.7 months (range, 24-65 months), and there were no age or sex differences between the groups. No patients were lost to follow-up. The primary mechanism of injury in the anterior cohort was a formal dislocation event (82.5% [85/103], of which 46% [39/85] required reduction by a medical provider), followed by shoulder subluxation (12%, 12/103), and "other" (6%, 6/103; no forceful injury). No primary identifiable mechanism of injury was found in the posterior cohort for 78% (75/97) of patients; lifting and pressing (11%, 11/97) and contact injuries (10% [all football blocking], 10/97) were the common mechanisms that initiated symptoms. Only 10 patients (10.3%) in the posterior cohort sustained a dislocation. The most common complaints for patients with anterior instability were joint instability (80%) and pain with activities (32%). In the posterior cohort, the most common complaint was pain (90.7%); only 13.4% in this cohort reported instability as the primary complaint. Clinical outcomes after arthroscopic stabilization were significantly improved in both groups, but the anterior cohort had significantly better outcomes in all scores measured: ASES (preoperative: anterior 58.0, posterior 60.0; postoperative: anterior 94.2 vs posterior 87.7, P < .005), SANE (preoperative: anterior 50.0, posterior 60.0; postoperative: anterior 92.9 vs posterior 84.9, P < .005), and WOSI (preoperative: anterior 55.95, posterior 60.95; postoperative: anterior 92% of normal vs posterior 84%, P < .005). CONCLUSION This study outlines clear distinctions between anterior and posterior shoulder instability in terms of presentation and clinical findings. Patients with anterior instability present primarily with an identifiable mechanism of injury and complaints of instability, whereas most patients with classic posterior instability have no identifiable mechanism of injury and their primary symptom is pain. Anterior instability outcomes in this matched cohort were superior in all domains versus posterior instability after arthroscopic stabilization, which further highlights the differences between anterior and posterior instability.

Abstract
BACKGROUND The arthroscopic "bony Bankart bridge" (BBB) repair technique was recently shown to successfully restore shoulder stability at short-term follow-up, but longer-term outcomes have not yet been described. PURPOSE To report the outcomes at minimum 5-year follow-up after BBB repair for anterior shoulder instability with a bony Bankart lesion. STUDY DESIGN Case series; Level of evidence, 4. METHODS Patients were included if they sustained a bony Bankart lesion, were treated with a BBB technique, and were at least 5 years postoperative. Patients were excluded if they underwent concomitant rotator cuff repair or an open bone fragment reduction. All patients were assessed with the following measures preoperatively and at final evaluation: QuickDASH (Quick Disabilities of the Arm, Shoulder and Hand), American Shoulder and Elbow Surgeons, Single Assessment Numeric Evaluation, and 12-Item Short Form Health Survey (SF-12) Physical Component Summary. RESULTS From 2008 to 2012, 13 patients who underwent BBB met the inclusion criteria with a mean age of 39.6 years (range, 19.1-68.8 years) and a mean follow-up of 6.7 years (range, 5.1-9.0 years). Mean time from most recent injury to surgery was 6.3 months (range, 1 day-36 months). The mean glenoid bone loss was 22.5% (range, 9.1%-38.6%). Mean SF-12 scores demonstrated significant improvement from 45.8 (SD, 9.7) preoperatively to 55.1 (SD, 5.9) at a mean follow-up of 6.7 years. At final follow-up, the mean American Shoulder and Elbow Surgeons score was 93.1 (range, 68.3-100); the mean QuickDASH score, 6.2 (range, 0-25); and the mean Single Assessment Numeric Evaluation score, 92.8 (range, 69-99). None of the patients progressed to further shoulder surgery. Three of 13 patients (23%) reported subjective recurrent instability. At final follow-up, 9 of 12 (75%) patients indicated that their sports participation levels were equal to their preinjury levels. Median patient satisfaction at final follow-up was 10 of 10 points (range, 3-10). CONCLUSION The arthroscopic BBB technique for patients with anterior bony Bankart lesions can restore shoulder stability, yield durable improvements in clinical outcomes, and provide a high return-to-sport rate at a minimum 5-year follow-up. Three of 13 patients experienced postoperative symptoms of instability but did not undergo further stabilization surgery.

Abstract
BACKGROUND Although previous literature has described the relevant anatomy for an open anterior Bankart approach of the shoulder, there is little known regarding the anatomic relationship changes in the neurovascular structures after an open Latarjet procedure. PURPOSE To define the neurovascular anatomy of the native shoulder in relation to the coracoid and to define the anatomy after the Latarjet procedure in relation to the glenoid to determine distances to these neurovascular structures with and without neurolysis of the musculocutaneous nerve (MCN) from the conjoint tendon. STUDY DESIGN Descriptive laboratory study. METHODS Fourteen fresh-frozen male cadaveric shoulders (7 matched pairs) were utilized. The distances of 7 neurovascular structures (the main trunk of the MCN at its insertion into the conjoint tendon, the MCN at its closest location to the coracoid process, the lateral cord of the plexus, the split of the lateral cord and MCN, the posterior cord of the plexus, the axillary nerve, and the axillary artery) to pertinent landmarks were first measured in the native state in relation to the coracoid. After the Latarjet procedure, these landmarks were measured in relation to the glenoid. In addition, measurements of the MCN distances were performed both with and without neurolysis of the MCN from the conjoint tendon. All measurements were performed using digital calipers and reported as medians with ranges. RESULTS The median MCN entry into the conjoint tendon was 56.5 mm (range, 43.0-82.2 mm) and 57.1 mm (range, 23.5-92.9 mm) from the tip of the coracoid in the neurolysis group and nonneurolysis group, respectively ( P = .32). After the Latarjet procedure, the median MCN entry into the conjoint tendon was 43.8 mm (range, 20.2-58.3 mm) and 35.6 mm (range, 27.3-84.5 mm) from the 3-o'clock position of the glenoid in the neurolysis and nonneurolysis groups, respectively ( P = .83). The median MCN entry into the conjoint tendon was 35.6 mm (range, 25.1-58.0 mm) and 36.3 mm (range, 24.4-77.9 mm) from the 6-o'clock position in the neurolysis group and nonneurolysis group, respectively ( P = .99). After the Latarjet procedure, the closest neurovascular structures in relation to both the 3-o'clock and 6-o'clock positions to the coracoid were the axillary nerve at a median 27.4 mm (range, 19.8-40.0 mm) and 27.7 mm (range, 23.2-36.1 mm), respectively. CONCLUSION This study identified a minimum distance medial to the glenoid after the Latarjet procedure to be approximately 19.8 mm for the axillary nerve, 23.6 mm for the posterior cord, and 24.4 mm and 20.2 mm for the MCN without and with neurolysis, respectively. Neurolysis of the MCN did not significantly change the distance of the nerve from pertinent landmarks compared with no neurolysis, and routine neurolysis may not be indicated. However, the authors still advise that there may be clinical benefit to performing neurolysis during surgery, especially given that the short length of the MCN puts it at risk for traction injuries during the Latarjet procedure. CLINICAL RELEVANCE The findings of this study provide an improved understanding of the position of the neurovascular structures after the Latarjet procedure. Knowledge of these minimum distances will help avoid iatrogenic damage of the neurovascular structures when performing procedures involving transfer of the coracoid process.

Abstract
BACKGROUND Anterior glenoid reconstruction with fresh distal tibia allograft (DTA) has been described for management of recurrent shoulder instability, with encouraging early outcomes; however, no comparative data with the Latarjet procedure are available. PURPOSE The purpose of this study was to compare the clinical outcomes between patients undergoing DTA and a matched cohort of patients undergoing Latarjet. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS A review was conducted of prospectively collected data for patients with a minimum 15% anterior glenoid bone loss who underwent shoulder stabilization via either the DTA or Latarjet procedure and had a minimum follow-up of 2 years. Consecutive patients undergoing DTA were matched in a 1-to-1 format to patients undergoing Latarjet by age, body mass index, history of contact sports, and number of previous shoulder operations. Patients were evaluated pre- and postoperatively with a physical examination and the following outcome assessments: Simple Shoulder Test, visual analog scale, American Shoulder and Elbow Surgeons, Western Ontario Shoulder Instability Index, and Single Assessment Numeric Evaluation. Complications, reoperations, and episodes of recurrent instability were analyzed. Statistical analysis was performed with Student t tests, with P < .05 considered significant. RESULTS A total of 100 patients (50 Latarjet, 50 DTA) with a mean ± SD age of 25.6 ± 6.1 years were analyzed at 45 ± 20 months (range, 24-111) after surgery. Thirty-two patients (64%) in each group underwent prior ipsilateral shoulder surgery (range, 1-3). Patients undergoing DTA had significantly greater glenoid bone loss defects when compared with patients undergoing Latarjet (28.6% ± 7.4% vs 22.4% ± 10.3%, P = .001). Patients in both groups experienced significant improvements in all outcome scores after surgery ( P < .05 for all). No significant differences were found in postoperative scores between the Latarjet and DTA groups: visual analog scale (0.67 ± 0.97 vs 1.83 ± 2.31), American Shoulder and Elbow Surgeons (91.06 ± 8.78 vs 89.74 ± 12.66), Western Ontario Shoulder Instability Index (74.30 ± 21.84 vs 89.69 ± 5.50), or Single Assessment Numeric Evaluation (80.68 ± 7.21 vs 90.08 ± 13.39) ( P > .05 for all). However, patients in the Latarjet group had superior Simple Shoulder Test outcomes ( P = .011). There were 10 complications (10%) for the entire cohort, including 5 in the Latarjet group (3 of which required reoperation) and 5 in the DTA group (3 of which required reoperation). The overall recurrent instability rate was 1% (1 patient). CONCLUSION Fresh DTA reconstruction for recurrent anterior shoulder instability results in a clinically stable joint with similar clinical outcomes as the Latarjet procedure. Longer-term studies are needed to determine if these results are maintained over time.

Abstract
The Latarjet procedure is a well-known, safe and reliable technique to treat primary or recurrent anterior dislocations or subluxations, with or without hyperlaxity, with or without glenoid bone loss. Both the open and the arthroscopic methods produce excellent clinical results, with a low rate of recurrent instability. There have been concerns of a higher surgical complication rate associated with this procedure, however, large reviews reported an overall complication rate in the open Latarjet procedure of 15%. Meticulous surgical technique and a good understanding of the local anatomy can help to avoid the complications but postoperative shoulder arthritis and frequent bone block osteolysis remain unsolved additional challenges, which require further research. There are 2 main factors to further improve the clinical outcome and patient satisfaction: careful patient selection with good surgical indication, and reducing complications with adequate surgical techniques. The aim of this study is to provide the current overview of the contraindications and complications of the Latarjet procedure.

Abstract
BACKGROUND The debate continues regarding the optimal treatment of intercollegiate contact athletes with in-season anterior shoulder instability. PURPOSE To examine return to sport and recurrent instability in the season after the index in-season anterior instability event. STUDY DESIGN Cohort study; Level of evidence, 2. METHODS Forty-five contact intercollegiate athletes treated nonoperatively or with arthroscopic stabilization were prospectively followed in a multicenter observational study to evaluate return to play (RTP) and recurrent instability in the season after an initial in-season anterior glenohumeral instability event. Baseline data collection included sport played, previous instability events, direction of instability, type of instability (subluxation or dislocation), and treatment method (nonoperative management or arthroscopic stabilization). All nonoperatively treated athletes underwent a standardized accelerated rehabilitation program without shoulder immobilization. Surgical stabilization was performed arthroscopically in all cases, and successful RTP was evaluated during the next competitive season after complete rehabilitation. RESULTS Thirty-nine of 45 intercollegiate contact athletes had remaining National Collegiate Athletic Association eligibility and were followed through the subsequent competitive season after the index instability event. Of the 10 athletes electing nonoperative treatment, 4 (40%) successfully returned to play without recurrence during the subsequent season. Of the 29 athletes treated surgically, 26 (90%) were able to successfully return to play without recurrence the following season (recurrence: n = 1; inadequate function: n = 2). Athletes who underwent surgical reconstruction before the next season were 5.8 times (95% CI, 1.77-18.97; P = .004) more likely to complete the subsequent season without recurrent instability. Of the 29 athletes electing surgical stabilization, there was no difference (risk ratio, 0.95; 95% CI, 0.10-9.24; P > .99) in RTP between the 9 stabilized after a single instability event (90% RTP rate) and the 20 stabilized after multiple in-season recurrent instability events (89% RTP rate). CONCLUSION Collegiate contact and collision athletes with in-season anterior shoulder instability are significantly more likely to successfully return to sport without subsequent instability events the next season if they undergo surgical repair in the off-season.

Abstract
BACKGROUND Locked anterior shoulder (LAS) with static instability and anterior glenoid bone loss is challenging in the elderly population. Reverse shoulder arthroplasty (RSA) has been employed in treating these patients. No study has compared RSA for LAS with classically indicated RSA. METHODS A retrospective case-control study of patients treated with RSA for LAS with glenoid bone loss and static instability was performed using matched controls treated with primary RSA for classic indications. Twenty-four cases and 48 controls were evaluated. Average follow-up was 25.5 months, and median age was 76 years. Motion, outcome assessments, and postoperative radiographs were compared. RESULTS Preoperatively, LAS had significantly less rotation and lower baseline outcome scores. Glenoid bone grafting was more common (P = .05) in the control group (26%) than in the LAS group (6.3%). Larger glenospheres were used more often (P = .001) in the LAS group (75%) than in the control group (29%). Both groups demonstrated significant improvements in pain, function, and outcome scores. Postoperatively, the control group had significantly better elevation and functional outcome scores. With the exception of flexion and Simple Shoulder Test score, effectiveness of treatment was similar between groups. Postoperative acromion stress fractures were seen in 21% of LAS patients and 9% of controls (P = .023) with a predominance of type 3 fractures in LAS. Two LAS patients remained dislocated. CONCLUSION Patients with LAS treated with RSA can anticipate improvements in pain and function by use of larger glenospheres, often without the need for glenoid bone grafting. Worse postoperative motion and function and a higher incidence of acromion stress fracture may be expected.

Abstract
BACKGROUND Combined defects of the glenoid and humeral head are often a cause for recurrent shoulder instability. PURPOSE/HYPOTHESIS The aim of this study was to evaluate the influence of combined bony lesions on shoulder instability through varying glenohumeral positions. The hypothesis was that instability due to combined defects would be magnified with increasing abduction and external rotation. STUDY DESIGN Controlled laboratory study. METHODS Eighteen cadaveric shoulders were tested. Experiments were performed at combinations of glenohumeral abduction angles of 20°, 40°, and 60° and external rotations of 0°, 40°, and 80°. The various glenoid defect sizes created were 10%, 20%, and 30% of the glenoid width. Four humeral head defects were created based on humeral head diameter (6%, 19%, 31%, and 44%). Each experiment consisted of translating the glenoid in a posterior direction to simulate an anterior dislocation under a 50-N load. The instability was measured as a percentage of intact translation (ie, loss in translational distance normalized to the no-defect condition). RESULTS At 20° of abduction, instability increased from 100% to 85%, 70%, and 43% with increasing glenoid defect sizes of 10%, 20% and 30%, respectively, with a 6% humeral head defect. However, at a functional arm position of apprehension, these values were significantly decreased (P < .05) for humeral head defect sizes of 19%, 31%, and 44%, with translation values of 49%, 27%, and 2%, respectively. CONCLUSION A humeral defect leads to rotational instability with the arm rotated into a functional position rather than a resting position. However, a significant glenoid defect can lead to loss of translation independent of changes in arm position. Combined defects as large as 44% of humeral head and 20% glenoid did not show instability at 20° of abduction and neutral position; however, defects as small as 19% humeral defect and 10% glenoid defect led to significant instability in the position of apprehension. CLINICAL RELEVANCE Instability at lower levels of abduction and external rotation clinically indicates larger bony defects and may need to be directly addressed, depending on the patient's age and function.

Abstract
BACKGROUND Glenohumeral joint (GHJ) dislocations are common, and the resulting shoulder instability is often treated with arthroscopic stabilization. These procedures result in favorable clinical outcomes, but abnormal GHJ motion may persist, which may place patients at risk for developing osteoarthritis. However, the effects of shoulder instability and arthroscopic stabilization on GHJ motion are not well understood. HYPOTHESIS GHJ motion is significantly influenced by anterior instability and arthroscopic stabilization, but postsurgical measures of GHJ motion are not different from those of control subjects. STUDY DESIGN Controlled laboratory study. METHODS In vivo GHJ motion was measured by applying a computed tomographic model-based tracking technique to biplane radiographic images acquired during an apprehension test in healthy control subjects (n = 11) and anterior instability patients (n = 11). Patients were tested before surgery and at 6 months after surgery. Control subjects were tested once. Shoulder strength, active range of motion (ROM), and the Western Ontario Shoulder Instability (WOSI) index were also measured. RESULTS Before surgery, the humerus of the instability patients during the apprehension test was located significantly more anteriorly on the glenoid (7.9% of glenoid width; 2.1 mm) compared with that of the controls (P = .03), but arthroscopic stabilization moved this joint contact location posteriorly on the glenoid (4.7% of glenoid width; 1.1 mm; P = .03). After surgery, GHJ excursion during the apprehension test was significantly lower (14.7% of glenoid width; 3.6 mm) compared with presurgical values (19.4% of glenoid width; 4.7 mm; P = .01) and with that of the controls (22.4% of glenoid width; 5.7 mm; P = .01). The external and internal rotation strength of patients was significantly lower than that of the controls before surgery (P < .05), but differences in strength did not persist after surgery (P > .17). External rotation ROM in patients was significantly lower than that in control subjects both before and after arthroscopic stabilization (P < .01). The WOSI score improved significantly, from 48.3 ± 13.1 presurgery to 86.3 ± 16.5 after surgery (P = .0002). CONCLUSION In patients with anterior instability, arthroscopic stabilization significantly improves measures of strength, ROM, and clinical outcome. However, GHJ excursion is not fully restored to levels seen in the control subjects. CLINICAL RELEVANCE Although arthroscopic stabilization satisfactorily restores most clinical outcome measures, GHJ excursion and external rotation ROM remain compromised compared with healthy control subjects and may contribute to the development of osteoarthritis in patients with anterior instability.

Abstract
BACKGROUND Traumatic glenohumeral joint (GHJ) dislocations are common, resulting in significant shoulder disability and pain. Previous research indicates that bony morphology is associated with an increased risk of injury in other joints (eg, the knee), but the extent to which bony morphology is associated with traumatic GHJ dislocation is unknown. This study assessed GHJ morphology in patients with anterior GHJ instability and in a control population of healthy volunteers. METHODS Bilateral computed tomography scans were used to measure GHJ morphology in both shoulders of 11 patients with instability and 11 control subjects. Specific outcome measures included the glenoid radius of curvature (ROC) in the anterior/posterior (A/P) and superior/inferior (S/I) directions, humeral head ROC, A/P and S/I conformity index, and A/P and S/I stability angle. RESULTS Compared with the control subjects, the glenoid of the instability the injured shoulder in patients with instability was flatter (ie, higher ROC) in the A/P (P = .001) and S/I (P = .01) directions and this finding was also true for uninjured, contralateral shoulder (A/P: P = .01, S/I: P = .03). No differences in GHJ morphology were detected between the instability patients' injured and contralateral shoulders (P > .07). Similarly, no differences in GHJ morphology were detected between the control subjects' dominant and nondominant shoulders (P > .51). CONCLUSIONS There are significant differences in GHJ morphology between healthy control subjects and both shoulders (injured and uninjured, contralateral) of patients diagnosed with anterior instability after GHJ dislocation. These findings are important clinically because they suggest that glenoid morphology may influence the risk of GHJ dislocation.

Abstract
BACKGROUND Coracoid transfer to a large glenoid defect is considered an excellent method to restore the surface area of the anteroinferior glenoid. However, there is little quantitative evidence supporting whether a coracoid graft can sufficiently restore the glenoid arc. PURPOSE To assess whether the Latarjet procedure can sufficiently restore the surface area of the glenoid. STUDY DESIGN Case series; Level of evidence, 4. METHODS A total of 44 patients who underwent a Latarjet operation for a large glenoid defect between February 2009 and July 2011 were enrolled in this study. Three-dimensional computed tomography was used to calculate the surface areas of the preoperative glenoid defect size and the reconstructed glenoid. Preoperative and postoperative clinical results also were assessed. RESULTS At the last follow-up, the mean visual analog scale score for instability during motion improved significantly from 5.1 points (range, 3-10 points) preoperatively to 1.3 points (range, 0-4 points) (P<.001). The mean deficit in external rotation at the side, external rotation at 90° of abduction, and internal rotation to the posterior were 10°±20°, 7°±16°, and 1.9°±4°, respectively (P=.004, .022, and .009, respectively). The overall recurrence rate was 4.5% (2 of 44 shoulders). The mean preoperative glenoid defect size was 157±38 mm2 (range, 141-239 mm2; 25.3%±6% of the intact glenoid surface). The mean surface area of the coracoid graft used for reconstruction was 152±34 mm2 (range, 146-236 mm2; 24.8%±5% of the intact glenoid surface). After the Latarjet procedure, the mean surface area of the reconstructed glenoid was 706±32 mm2 (range, 639-749 mm2). Finally, postoperative glenoid defect size was 5±11 mm2 (range, 3-28 mm2; 1.5%±2% of the intact glenoid surface). CONCLUSION The Latarjet procedure can provide satisfactory outcomes, including a low recurrence rate and reliable functional recovery. Defects at the anteroinferior glenoid were restored to nearly normal after coracoid transfer by use of the Latarjet procedure, which is an anatomically matched reconstruction.

Abstract
BACKGROUND Transfer of the coracoid (Bristow-Latarjet [B-L]) is used to stabilize anterior shoulder instability. We report the long-term results of our first 31 operations with this method. MATERIALS AND METHODS Thirty-six patients (mean age, 26.7 years) had a B-L repair from 1977 to 1979. Five patients died, and during 2012 to 2013, the remaining 31 shoulders had a follow-up with questionnaire, physical examination, Western Ontario Shoulder Instability Index, Subjective Shoulder Value, Subjective Assessment of Shoulder Function, subjective assessment of loss of motion, and radiologic imaging. RESULTS One patient required revision surgery because of recurrence and another because of repeat dislocation. Six patients reported subluxations. Eighteen patients (58%) were very satisfied, and 13 (42%) were satisfied. The mean Western Ontario Shoulder Instability Index score (100 possible) was 85, and the median score was 93. According to Samilson-Prieto classification of arthropathy of the shoulder, 39% were classified as normal, 27% as mild, 23% as moderate, and 11% as severe. The classification of arthropathy varied with observers and radiologic views. Age younger than 22 years at the primary dislocation meant less arthropathy at follow-up (P = .045). CONCLUSION The degree of arthropathy 33 to 35 years after the B-L repair seems to follow the natural history of shoulder dislocation with respect to arthropathic joint degeneration. Postoperative restriction of external rotation does not increase later arthropathy.

Abstract
BACKGROUND The purpose of this study was to evaluate and to grade the extent of filling into the Hill-Sachs lesion quantitatively by use of magnetic resonance arthrography after an arthroscopic remplissage procedure. METHODS The current study enrolled 23 patients who underwent arthroscopic Bankart repair with a remplissage procedure for a large or engaging Hill-Sachs lesion confirmed by arthroscopic findings. The postoperative filling index was classified into 5 categories by axial and sagittal views of T2-weighted images on magnetic resonance arthrography: complete filling (4 points); partial filling with minor defect (3 points); partial filling with major defect (2 points); minimal filling with significant free fluid level (1 point); and filling failure with dehiscence (0 point). Filling Index Score of Remplissage (FISOR) was also calculated from the total sum of points in the axial and sagittal planes and classified into 5 grades. RESULTS The FISOR was 8 points in 13 patients, 7 points in 2 patients, 6 points in 3 patients, 5 points in 1 patient, 4 points in 1 patient, 3 points in 1 patient, 2 points in 1 patient, and 0 point in 1 patient. According to the FISOR grades, these results were recorded as excellent in 15 patients (65.2%), good in 4 patients (17.4%), fair in 2 patients (8.7%), poor in 1 patient (4.3%), and no evidence of filling in 1 patient (4.3%). CONCLUSION The FISOR would be a useful measurement tool for the evaluation of structural outcomes after the remplissage procedure.

Abstract
BACKGROUND There is no consensus on the optimal treatment of in-season athletes with anterior shoulder instability, and limited data are available to guide return to play. PURPOSE To examine the likelihood of return to sport and the recurrence of instability after an in-season anterior shoulder instability event based on the type of instability (subluxation vs dislocation). Additionally, injury factors and patient-reported outcome scores administered at the time of injury were evaluated to assess the predictability of eventual successful return to sport and time to return to sport during the competitive season. STUDY DESIGN Cohort study (prognosis); Level of evidence, 2. METHODS Over 2 academic years, 45 contact intercollegiate athletes were prospectively enrolled in a multicenter observational study to assess return to play after in-season anterior glenohumeral instability. Baseline data collection included shoulder injury characteristics and shoulder-specific patient-reported outcome scores at the time of injury. All athletes underwent an accelerated rehabilitation program without shoulder immobilization and were followed during their competitive season to assess the success of return to play and recurrent instability. RESULTS Thirty-three of 45 (73%) athletes returned to sport for either all or part of the season after a median 5 days lost from competition (interquartile range, 13). Twelve athletes (27%) successfully completed the season without recurrence. Twenty-one athletes (64%) returned to in-season play and had subsequent recurrent instability including 11 recurrent dislocations and 10 recurrent subluxations. Of the 33 athletes returning to in-season sport after an instability event, 67% (22/33) completed the season. Athletes with a subluxation were 5.3 times more likely (odds ratio [OR], 5.32; 95% CI, 1.00-28.07; P = .049) to return to sport during the same season when compared with those with dislocations. Logistic regression analysis suggests that the Western Ontario Shoulder Instability Index (OR, 1.05; 95% CI, 1.00-1.09; P = .037) and Simple Shoulder Test (OR, 1.03; 95% CI, 1.00-1.05; P = .044) administered after the initial instability event are predictive of the ability to return to play. Time loss from sport after a shoulder instability event was most strongly and inversely correlated with the Simple Shoulder Test (P = .007) at the time of initial injury. CONCLUSION In the largest prospective study evaluating shoulder instability in in-season contact athletes, 27% of athletes returned to play and completed the season without subsequent instability. While the majority of athletes who return to sport complete the season, recurrent instability events are common regardless of whether the initial injury was a subluxation or dislocation.

Abstract
BACKGROUND Anterior shoulder instability with bone loss can be treated successfully with the modified Bristow procedure. Opinions vary regarding the role of the soft-tissue sling created by the conjoined tendon after transfer. Therefore, the aim of this study was to determine the effect of the modified Bristow procedure and conjoined tendon transfer on glenohumeral translation and kinematics after creating anterior instability. METHODS Eight cadaveric shoulders were tested with a custom shoulder testing system. Range-of-motion, translation, and kinematic testing was performed in 60° of glenohumeral abduction in the scapular and coronal planes under the following conditions: intact joint, Bankart lesion with 20% glenoid bone loss, modified Bristow procedure, and soft tissue-only conjoined tendon transfer. RESULTS A Bankart lesion with 20% bone loss resulted in significantly increased external rotation and translation compared with the intact condition (P < .05), as well as an anterior shift of the humeral head apex at all points of external rotation. Both the modified Bristow procedure and soft-tissue Bristow procedure maintained the increase in external rotation but resulted in significantly decreased translation (P < .05). There was no difference in translation between the 2 reconstructions. CONCLUSIONS The increase in external rotation suggests that the modified Bristow procedure does not initially restrict joint motion. Translational stability can be restored in a 20% bone loss model without a bone block, suggesting the importance of the soft-tissue sling.

Abstract
BACKGROUND Glenoid bone loss is a factor that has been inversely associated with the success of shoulder instability repair. Recently, patients with an anterior labroligamentous periosteal sleeve avulsion (ALPSA) lesion have also been identified as having a higher failure rate after surgical repair. PURPOSE To determine differences in the amount of glenoid bone loss and to compare demographic factors of instability in patients with and without ALPSA tears. STUDY DESIGN Case-control study; Level of evidence, 3. METHODS Over a 3-year period, all patients (N = 83) who were treated for anterior shoulder instability at a single institution were reviewed retrospectively. A total of 39 (47%) were identified as having an ALPSA lesion and 44 (53%) as having no ALPSA tear. Glenoid bone loss was determined in 2 ways: (1) radiographically by 3-dimensional computed tomography (3D CT) (humeral head digitally subtracted by 3 blinded observers) and (2) with arthroscopic techniques at the time of surgery. Demographic data such as the time from the initial instability event to advanced imaging and surgery were noted. These data were then analyzed with the Student t test to determine any significant differences between the 2 groups. RESULTS The patients with an ALPSA lesion had more preoperative instability events than those without (8.2 vs 3.6, respectively; P = .04). The mean glenoid bone loss measured by 3D CT was 12.7% (range, 0%-22.3%) for those with ALPSA tears versus 6.25% (range, 0%-23.1%) for those without (P = .002). The mean duration of total instability for those with ALPSA tears was 42.9 months versus 46.3 months for those without (P = .95). Lastly, the mean bone loss based on arthroscopic measures was 11.4% for patients with ALPSA tears and 4.3% for those without ALPSA tears (P = .017). From the existing magnetic resonance imaging/arthrography scans reviewed, 82% of patients could be correctly identified as having an ALPSA lesion. CONCLUSION Patients with anterior shoulder instability who have an ALPSA lesion have nearly twice the amount of glenoid bone loss as those with a standard Bankart tear (no ALPSA lesion). Patients with ALPSA lesions had statistically more instability events, and this may be an additional factor in either developing an ALPSA lesion or glenoid bone loss or both.

Abstract
BACKGROUND There has been no study about treatment guidelines for arthroscopic repair according to the size of bony Bankart lesions of less than 25% of the glenoid width. PURPOSE To evaluate the results of arthroscopic repair for bony Bankart lesions managed with different repair techniques based on their size. STUDY DESIGN Case series; Level of evidence, 4. METHODS Between March 2005 and February 2009, 44 of 52 consecutive patients with bony Bankart lesions with a size of less than 25% of the entire glenoid were managed with an arthroscopic approach. Of those patients, 34 (77%) were available for outcome analysis at a minimum 24 months' follow-up (mean, 34 months; range, 24-60 months). The size of the fragment was measured by computed tomography (CT) and classified as small (<12.5% of the inferior glenoid width) and medium (12.5%-25%). Sixteen lesions were classified as small (small group), and 18 were classified as medium (medium group). For small lesions, capsulolabral repair using suture anchors without excision of the bony fragment was performed. For medium lesions, anatomic reduction and fixation using suture anchors was performed, and the adequacy of reduction was assessed by CT postoperatively. The visual analog scale (VAS) for pain score and modified Rowe score for bony Bankart repair were compared and the postoperative recurrence rate investigated. RESULTS One patient from the small group (6.3%) and 1 patient without anatomic reduction of the bony fragment in the medium group (5.6%) experienced traumatic redislocations. The mean VAS score improved from 1.7 preoperatively to 0.5 at final follow-up, and the mean Rowe score improved from 59 to 91 (both P < .001). The mean postoperative Rowe scores increased from 58 to 92 in the small group and from 60 to 91 in the medium group (both P < .001). Residual joint incongruity measuring ≤2 mm on both axial and coronal scans, which was considered an anatomic reduction, was present in 14 cases (77.8%) in the medium group. In the medium group, the mean postoperative Rowe scores increased from 60 to 95 in cases of anatomic reduction compared with an increase from 56 to 76 in cases of nonanatomic reduction. The Rowe score was statistically correlated with anatomic reduction of medium-sized bony fragments (P = .046). CONCLUSION In small Bankart lesions, restoration of capsulolabral soft tissue tension alone may be enough, whereas in medium lesions, the osseous architecture of the glenoid should be reconstructed for more functional improvement and less pain.

Abstract
OBJECTIVE To provide treatment guidelines for rehabilitation after ligamentous and labral surgery of the shoulder. DATA SOURCES We searched Index Medicus for the last 10 years using the key words "shoulder instability," "shoulder exercises," and "shoulder surgery." DATA SYNTHESIS Detailed rehabilitation programs for patients with anterior shoulder instability reconstructions can be found in the literature, but many are based on anecdotal evidence and clinical observation. Randomized, prospective outcome studies on these rehabilitation protocols have not been performed. Therefore, we offer a performance- and criteria-based guideline for rehabilitation that is rooted in basic science, surgeons' recommendations, clinical experience, and common sense. CONCLUSIONS/RECOMMENDATIONS To return an athlete to the preinjury level of function, range of motion, strengthening, proprioception, and functional activities must be used judiciously, keeping healing constraints and arthrokinematics in mind.
