A comprehensive comparison and evaluation of surgical techniques for anterior shoulder instability: a Bayesian network meta-analysis. J Shoulder Elbow Surg 2023; 32:e531-e547. [PMID: 37541334 DOI: 10.1016/j.jse.2023.07.004] [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: 12/05/2022] [Revised: 06/27/2023] [Accepted: 07/02/2023] [Indexed: 08/06/2023]
Abstract
BACKGROUND Anterior shoulder instability is a common clinical problem; however, conflicting evidence exists regarding optimal treatment algorithms. We perform a comparative analysis of stabilization techniques used for recurrent anterior shoulder instability to identify the one associated with the lowest rate of recurrent instability. We additionally explore how glenoid bone loss and osseus lesions affect recurrence rates. METHODS PubMed, MEDLINE, Embase, and Cochrane databases were searched for clinical studies comparing surgical techniques for anterior shoulder instability. Two team members independently assessed all potential studies for eligibility and extracted data. Each included study underwent a risk of bias assessment using the Cochrane risk of bias summary tool. The primary outcome of interest was the rate of recurrent instability, which underwent a Bayesian network meta-analysis. Additional analyses were performed relating to the degree of glenoid bone loss and the presence of osseous lesions. RESULTS Of 2699 studies screened, 52 studies with 4209 patients were included. Patients who underwent open Latarjet demonstrated the overall lowest rate of recurrent instability [log odds ratio (LOR) 1.93], whereas patients who underwent arthroscopic Bankart repair demonstrated the highest (LOR 2.87). When glenoid bone loss was 10% to 20%, open Latarjet had significantly lower recurrent instability (P = .0016) compared to arthroscopic Bankart repair. When glenoid bone loss increased from 0%-10% to 10%-20%, arthroscopic Bankart repair had a significantly increased rate of recurrence (P = .021). In the presence of an engaging Hill-Sachs lesion, both open Latarjet (P = .01) and arthroscopic Bankart with remplissage (P = .029) had significantly reduced recurrence rates compared to arthroscopic Bankart repair. Finally, regardless of procedure, the presence of a Hill-Sachs or bony Bankart lesion was associated with an increased risk of recurrent instability (r = 0.44, P = .0003, and r = 0.40, P = .006, respectively). CONCLUSION The open Latarjet has the overall lowest recurrent instability and significantly lower compared to arthroscopic Bankart repair in the setting of increasing glenoid bone loss. Bone loss between 0% and 10% results in similar outcomes across all procedures.

Abstract
Background This systematic scoping review aimed to describe the content of post-operative rehabilitation programmes, and outcome measures selection following stabilisation surgery for traumatic anterior shoulder dislocation (TASD). Methods An electronic search of Medline, EMBASE, CINAHL and AMED was conducted (2000-2021). Any cohort or clinical trial of patients receiving post-operative TASD rehabilitation were included. Study selection, data extraction and quality appraisal were undertaken by two independent reviewers. Results Twelve studies including fourteen treatment programmes were eligible. Period of post-operative immobilisation ranged from 1 day to 6 weeks, with exercise introduced between 1 and 7 weeks. Strengthening exercises were introduced between 1 and 12 weeks. Two studies described "accelerated" rehabilitation programmes, differing in immobilisation period and exercise milestones. No increased recurrence was reported in professional footballers. Two studies compared rehabilitation programmes, one not randomised, the other 18 years old. There was variability in selected outcomes measures, with only 4 studies using a common measure. Discussion There is minimal evidence to guide post-operative rehabilitation, variability in immobilisation periods and when exercise is introduced. There is no consensus on the definition of accelerated rehabilitation, or outcome measure selection. Clinical consensus of standardised terminology and stages of rehabilitation is required prior to efficacy studies.

Abstract
Osteoarthritis is a common cause of morbidity in an increasingly aging population. Although the weight-bearing joints of the leg and foot are frequently affected by osteoarthritis, degenerative changes in the joints of the upper extremity are likewise common and can be both particularly debilitating for affected individuals and uniquely challenging for the health care providers managing it. The present review seeks to overview the epidemiology, anatomy, diagnosis, and management of osteoarthritis in the joints of the shoulder, elbow, and hand with the intent of providing accessible and relevant information to the range of medical professionals involved in patient care.

The Glenoid Track Paradigm Does Not Reliably Affect Military Surgeons’ Approach to Managing Shoulder Instability. Arthrosc Sports Med Rehabil 2023; 5:e403-e409. [PMID: 37101867 PMCID: PMC10123446 DOI: 10.1016/j.asmr.2023.01.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2022] [Accepted: 01/17/2023] [Indexed: 02/20/2023] Open
Abstract
Purpose To report the frequencies of surgical stabilization procedures performed by military shoulder surgeons and to use decision tree analysis to describe how bipolar bone loss affects surgeons' decision to perform arthroscopic versus open stabilization procedures. Methods The Military Orthopaedics Tracking Injuries and Outcomes Network (MOTION) database was queried for anterior shoulder stabilization procedures from 2016 to 2021. A nonparametric decision tree analysis was used to generate a framework for classifying surgeon decision making based on specified injury characteristics (labral tear location, glenoid bone loss [GBL], Hill-Sachs lesion [HSL] size, and on-track vs off-track HSL). Results A total of 525 procedures were included in the final analysis, with a mean patient age of 25.9 ± 7.2 years and a mean GBL percentage of 3.6% ± 6.8%. HSLs were described based on size as absent (n = 354), mild (n = 129), moderate (n = 40), and severe (n = 2) and as on-track versus off-track in 223 cases, with 17% (n = 38) characterized as off-track. Arthroscopic labral repair (n = 428, 82%) was the most common procedure, whereas open repair (n = 10, 1.9%) and glenoid augmentation (n = 44, 8.4%) were performed infrequently. Decision tree analysis identified a GBL threshold of 17% or greater that resulted in an 89% probability of glenoid augmentation. Shoulders with GBL less than 17% combined with a mild or absent HSL had a 95% probability of an isolated arthroscopic labral repair, whereas a moderate or severe HSL resulted in a 79% probability of arthroscopic repair with remplissage. The presence of an off-track HSL did not contribute to the decision-making process as defined by the algorithm and data available. Conclusions Among military shoulder surgeons, GBL of 17% or greater is predictive of a glenoid augmentation procedure whereas HSL size is predictive of remplissage for GBL less than 17%. However, the on-track/off-track paradigm does not appear to affect military surgeons' decision making. Level of Evidence Level III, retrospective cohort study.

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
Shoulder instability in hypermobile Ehlers-Danlos syndrome can result in lifelong pain and functional disability. Treatment in this population is complicated by the severe degree of instability as well as the underlying abnormalities of the joint connective tissue. Appropriate care for these patients requires a thorough understanding of the natural history of their disease, knowledge of the available treatment options, and certain special considerations. This article reviews the pathoanatomy, recognition, and management of shoulder instability in the patient with hypermobile Ehlers-Danlos syndrome.

High Variability of the Definition of Recurrent Glenohumeral Instability: An Analysis of the Current Literature by a Systematic Review. Arthrosc Sports Med Rehabil 2021; 3:e951-e966.

Abstract
Purpose To determine the definitions for recurrence used in the literature, assess the consensus in using these definitions, and determine the impact of these definitions on recurrence rates. Methods A literature search was performed in PubMed and EMBASE including studies from 2000 to 2020 reporting on recurrence rates after anterior arthroscopic shoulder instability surgery. Dislocation, apprehension, subluxation and recurrence rates were compared. Results Ninety-one studies were included. In 68% of the eligible studies, recurrence rates are not well defined. Thirty (33%) studies did not report on dislocations, 45 (49%) did not report on subluxations, and 58 (64%) did not report on apprehension. Seventeen different definitions for recurrence of instability, 4 definitions of dislocations, and 8 definitions of subluxation were used. Conclusion Recurrence rates are poorly specified and likely underreported in the literature, hampering comparison with results of other studies. This highlights the need for a consensus on definition of recurrence across shoulder instability studies. We recommend not using the definition recurrence of instability anymore. We endorse defining dislocations as a radiographically confirmed dislocation or a dislocation that is manually reduced, subluxations as the feeling of a dislocation that can be (spontaneously) reduced without the need for a radiographically confirmed dislocation, and a positive apprehension sign as fear of imminent dislocation when placing the arm in abduction and external rotation during physical examination. Reporting on the events resulting in a dislocation or subluxation aids in making an estimation of the severity of instability. Level of Evidence Level IV, systematic review.

Abstract
Background High recurrence rates have been reported after anterior shoulder dislocations, regardless of the treatment utilized. However, the definition of recurrent instability has been inconsistent, making a comparison between studies difficult. Purpose To report on the nature with which the rate of recurrent instability is reported after arthroscopic Bankart repair, across all levels of evidence, and to analyze factors that may affect the reported rate of recurrence. Study Design Systematic review; Level of evidence, 4. Methods A systematic review of the literature was performed by searching PubMed, the Cochrane Central Register of Controlled Trials, Embase, and ClinicalTrials.gov for studies published within the dates of January 2008 and September 2018. Studies in English that reported on the recurrence of instability after arthroscopic Bankart repair for anterior shoulder instability were considered for inclusion in this review. A meta-regression was performed to test for a linear association between the reported recurrence rate and several continuous covariates, including mean age at surgery, mean length of follow-up, attrition rate (loss to follow-up percentage), and percentage of male patients. Results A trim-and-fill meta-analysis yielded an estimated overall recurrence rate of 17.4% (95% CI, 14.3%-20.9%). There was a significant difference in the recurrence rate depending on the level of evidence (Q(3) = 10.98; P = .012). Significant associations were found with the recurrence rate through the meta-regression, including a negative association with mean age (P = .009), a positive association with mean follow-up time (P = .002), and a positive association with attrition rate (P = .035). Conclusion A call for standardization is necessary for reporting outcomes of anterior instability after arthroscopic Bankart repair, especially with regard to the reporting of recurrence/failure rates, with careful consideration of the effects that may occur from patient demographics and study design. With no current recommendations for deeming failure, we suggest that all forms of instability be accounted for when determining a failed treatment procedure, with future studies placing an emphasis on greater control of the study design.

Abstract
Background Anterior shoulder instability is the most common sequela of shoulder dislocation and can result in repeated dislocations or subluxation of the glenohumeral joint. Anterior shoulder instability can be treated conservatively or surgically with several procedures. Purpose To date, arthroscopic Bankart is the most common surgical procedure for the treatment of anterior shoulder instability. No previous studies have compared all anterior shoulder surgical procedures. In this study, the authors performed a systematic review of journal articles describing all surgical procedures for anterior shoulder instability to determine the scientific evidence and level of recommendation. Study Design Systematic review; Level of evidence, 4. Method A comprehensive literature search was conducted (July 19, 2016) with 4 reputed databases: PubMed, EMBASE, the Cochrane databases, and Web of Science. The articles found in the literature search were screened by 2 reviewers on the basis of their titles, abstracts, and full text. Data were extracted from relevant studies, and potentially relevant records were selected for full-text review. Included articles were classified according to their scientific quality (level of evidence, 1-5). The studies were then combined for each surgical procedure, and a grade of recommendation was assigned for each procedure: grade A, treatment recommendation based on level 1 evidence studies; B, based on level 2 or 3 evidence studies; C, based on level 4 or 5 evidence and could represent conflicting results; or I, insufficient evidence to recommend a treatment. As such, the grade of recommendation provides a summary score for the quality and quantity of available literature to support the surgical procedures reviewed here. Results The systematic literature review generated 11,281 articles. After screening, 655 articles were included. Results revealed 31 surgical procedures for shoulder instability following dislocation: 10 surgical procedures were given an A or B recommendation; 11, a C recommendation; and 10, an I recommendation. Conclusion This review identified many surgical procedures to treat anterior shoulder instability. Ten of these surgical procedures had an abundant amount of published articles to describe their safety and efficacy. Arthroscopic Bankart and open Bankart were the most commonly reported procedures that cite satisfactory postoperative outcomes and limited complications. Publications on the other surgical procedures were less common. Surgeons should be careful when recommending surgery, and they should choose the appropriate surgical procedure based on evidence-based literature.

Can arthroscopic Bankart repairs using suture anchors restore equivalent stability to open repairs in the management of traumatic anterior shoulder dislocation? A meta-analysis. J Orthop Sci 2018; 23:935-941. [PMID: 30057323 DOI: 10.1016/j.jos.2018.06.016] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/26/2017] [Revised: 04/12/2018] [Accepted: 06/07/2018] [Indexed: 01/11/2023]
Abstract
BACKGROUND Recently, arthroscopic Bankart repairs have become much more popular than open repairs for the treatment of recurrent anterior shoulder instability. However, it is unclear whether the modern arthroscopic Bankart repairs using suture anchors could restore equivalent stability to open repairs. We conducted a meta-analysis to compare arthroscopic Bankart repairs using suture anchors and open repairs in regard to clinical outcomes. METHODS A literature review was performed according to the PRISMA guidelines. PubMed was searched from January 1966 to January 2017. Studies were identified using the terms 'anterior shoulder dislocation' or 'recurrent anterior shoulder dislocation' and 'Bankart repair'. The search yielded 36 publications. After reading the full-text articles, we included four randomized controlled trials and five retrospective studies that compared arthroscopic and open repairs using suture anchors. RESULTS No significant differences were found between the two procedures in frank re-dislocation and revision surgery due to recurrence. However, the overall recurrent instability including not only re-dislocation but also subluxation and apprehension was significantly higher in arthroscopic repairs than in open repairs, while a significantly higher Rowe score and lower loss of external rotation at 90° of abduction were observed following arthroscopic repairs compared to open repairs. CONCLUSIONS Modern arthroscopic Bankart repairs using suture anchors provide an equivalent outcome compared to open repairs in terms of apparent re-dislocation, but overall recurrent instability including subluxation or apprehension was still significantly higher in arthroscopic repairs than in open repairs.

J Shoulder Elbow Surg 2017; 26:1873-1880. [PMID: 28688936 DOI: 10.1016/j.jse.2017.04.009] [Citation(s) in RCA: 40] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/11/2016] [Revised: 03/30/2017] [Accepted: 04/16/2017] [Indexed: 02/01/2023]
Abstract
BACKGROUND The purpose of this study was to perform a meta-analysis comparing open and arthroscopic surgery for the treatment of anterior shoulder instability by analyzing comparative studies during 2 different time intervals during the last 20 years. METHODS We conducted a systematic review of MEDLINE, Embase, Scopus, and Google Scholar. Two groups were created by dividing studies according to the year of publication, those published from 1995 to 2004 or from 2005 to 2015. Publication bias and risk of bias were assessed using the Cochrane Collaboration's tools. Heterogeneity was assessed using the I2 statistics. RESULTS A total of 22 studies (n = 1633) met the eligibility criteria. Comparison of the pooled estimate for all of these studies demonstrated no significant differences (P = .64) in clinical outcomes between open and arthroscopic shoulder stabilization. However, studies published from 1995 through 2004 demonstrated significant differences (P = .015) in recurrence rates favoring open surgery. In contrast, no significant differences (P = .09) in recurrence rates were observed for studies published from 2005 through 2015. The pooled estimate for all studies in both groups demonstrated significant differences (P = .001) in external rotation deficits between open and arthroscopic shoulder stabilization favoring arthroscopic surgery. CONCLUSION Despite advances in surgical techniques and devices during the last 20 years, either open or arthroscopic surgical treatment of anterior shoulder dislocation results in similar clinical outcomes. The recurrence rate for arthroscopic surgical stabilization has only marginally decreased, from 16.8% to 14.2%. However, during the earlier decade from 1995 through 2004, patients treated with arthroscopic surgery had twice the risk of recurrence compared with an open procedure.

Abstract
BACKGROUND AND PURPOSE Shoulder instability, a common issue among athletes who engage in contact sports, may lead to recurrent subluxations, or partial dislocations of the shoulder. Young athletic patients generally respond poorly to the nonsurgical treatments for shoulder instability that are commonly utilized. The purpose of this case report is to describe the effects of the treatment guided by the Mulligan Concept (MC) coupled with reflex neuromuscular stabilization (RNS) also known as reactive neuromuscular training (RNT), on an adolescent football player with glenohumeral joint (GHJ) instability who sustained a traumatic anterior subluxation. CASE DESCRIPTION The MC shoulder Mobilization with Movement (MWM) and RNS were applied in the treatment of an anterior shoulder subluxation injury sustained by a competitive adolescent football player. The Numeric Pain Rating Scale (NPRS), the Disability in the Physically Active (DPA) scale, the Patient specific Functional Scale (PSFS) and the Shoulder Pain and Disability Index (SPADI), were administered in order to identify patient-reported outcomes. OUTCOMES The shoulder MWM and RNS provided immediate relief of all of the patient's pain and increased ROM after the first treatment. The use of the coupled treatments resulted in a resolution of pain, an increase in range of motion (ROM) and improvement in perceived stability. A minimal clinically important difference (MCID) was reported on the NPRS and minimal detectable changes (MDC) were reported on the NRS and PSFS, after the first treatment. Equally important, MCIDs were reported on the DPA scale and SPADI scale over the course of treatment. DISCUSSION In this case report, the MC shoulder MWM, coupled with RNS, was an effective treatment for this patient and provided a short time to resolution (6 treatments; 19 days) compared to other descriptions of recovery in the literature. Clinicians treating patients who display anterior shoulder instability can consider this as a viable treatment option. Even though current literature indicates that surgery is an optimal treatment for reducing recurrent subluxations, in young athletes who participate in contact sports, the effects of surgery are substantial. Therefore, the consideration of the presented option for non-operative treatment is important. LEVEL OF EVIDENCE 4-Case Report.

Abstract
Background The optimal treatment for Bankart lesion remains controversial. Therefore, we performed this meta-analysis to compare the clinical outcomes of patients managed with open Bankart repair versus arthroscopic Bankart repair. Material/Methods After systematic review of online databases, a total of 11 trials with 1022 subjects were included. The methodological quality of randomized controlled trials (RCTs) was assessed using the PEDro critical appraisal tool, and non-RCTs were evaluated by Newcastle-Ottawa (NO) quality assessment tool. Outcomes of shoulder stability, range of motion (ROM), functional scales, and surgical times were analyzed. Results Data synthesis showed significant differences between the two strategies, with regards to stability of the shoulder (P=0.008, RR=0.94, 95% CI: 0.89 to 0.98), and ROM (P<0.001, SMD=−0.47, 95% CI: −0.72 to −0.22). Conclusions Open Bankart repair produced a more stable shoulder but had a relatively poor shoulder motion, compared with arthroscopic Bankart repair, for the treatment of Bankart lesion.

Abstract
PURPOSE This study aimed to systematically review the clinical outcomes and recurrence rates after arthroscopic anterior shoulder stabilization in the beach chair (BC) and lateral decubitus (LD) positions. METHODS The authors performed a systematic review of multiple medical databases using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. All English-language literature from 1990 to 2013 reporting clinical outcomes after arthroscopic anterior shoulder stabilization with suture anchors or tacks with a minimum 2-year follow-up period were reviewed by 2 independent reviewers. Data on recurrent instability rate, return to activity/sport, range of motion, and subjective outcome measures were collected. Study methodological quality was evaluated with the Modified Coleman Methodology Score (MCMS) and the Quality Appraisal Tool (QAT). To quantify the structured review of observational data, meta-analytic statistical methods were used. RESULTS Sixty-four studies (38 BC position, 26 LD position) met inclusion criteria. A total of 3,668 shoulders were included, with 2,211 of patients in the BC position (average age, 26.7 ± 3.8 years; 84.5% male sex) and 1,457 patients in the LD position (average age, 26.0 ± 3.0 years; 82.7% male sex). The average follow-up was 49.8 ± 29.5 months in the BC group compared with 38.7 ± 23.3 months in the LD group. Average overall recurrent instability rates were 14.65 ± 8.4% in the BC group (range, 0% to 38%) compared with 8.5% ± 7.1% in the LD group (range, 0% to 30%; P = .002). The average postoperative loss in external rotation motion (in abduction) was reported in 19 studies in the BC group and in13 studies in the LD group, with an average loss of 2.4° ± 1.0° and 3.6° ± 2.6° in each group, respectively (P > .05). CONCLUSIONS Excellent clinical outcomes with low recurrence rates can be obtained after arthroscopic anterior shoulder stabilization in either the BC or the LD position; however, lower recurrence rates are noted in the LD position. Additional long-term randomized clinical trials comparing these positions are needed to better understand the potential advantages and disadvantages of each position. LEVEL OF EVIDENCE Level IV, systematic review of studies with Level I through Level IV evidence.

Abstract
Background: Results of open Bankart repair have been well reported. However, less information is available outlining the timetable for return to play (RTP) in athletes after this procedure. Purpose: To review the current literature regarding (1) the timetable recommended for athletes to RTP after an open Bankart repair and (2) the objective criteria on which the decision to allow an athlete to RTP is based. Study Design: Systematic review; Level of evidence, 4. Methods: A comprehensive literature search was conducted of all relevant English-language articles using the electronic databases OVID and PubMed between the years 1947 and 2012 to identify open Bankart repair. Two reviewers screened articles for eligibility based on the following criteria: (1) an open Bankart repair, (2) a minimum follow-up of at least 8 months, (3) any report that described the procedure in athletes, and (4) any report that described the time for an athlete to RTP. All relevant data were collected and analyzed with regard to number of patients; mean follow-up; Rowe, Constant, and American Shoulder and Elbow (ASES) scores; redislocation rate; and return-to-sport timing. Results: In all, 559 relevant citations were identified, of which 29 articles met the inclusion criteria. The mean follow-up was 51.7 months (range, 8-162 months), and the mean age was 25.9 years (range, 21-31 years). The average Rowe score for all studies was 86.9 (range, 63-90). The average redislocation rate was 5.3%. Twenty-six of 29 studies cited a specific timetable for unrestricted RTP, with an average of 23.2 weeks (range, 12-36 weeks). Only 38% of authors reported sport-specific criteria for return to competition, with the majority allowing return to noncontact sports at 12 to 16 weeks, and the resumption of throwing/contact sports by 24 weeks. Three reports described specific functional parameters for RTP. Conclusion: The current review summarized return-to-play guidelines for athletic competition after open Bankart repair. These data may provide general guidelines to aid surgeons when determining the appropriate timetable to allow an athlete to return to unrestricted competition.

Abstract
BACKGROUND The purpose of this study was to examine outcomes following arthroscopic Bankart repair with the focus on strength after the repair. METHODS 56 shoulders with Bankart lesion were operated on arthroscopically. Gender, mechanism of the first dislocation, number of dislocations, dominant side, operated side and the number of anchors used for surgery were recorded. DASH and Oxford instability scoring systems were applied preoperatively and compared to scores at the 24-month follow-up. The scoring systems were also applied to contralateral shoulders at the 24th month of follow-up. Range of motion was measured with a goniometer. Muscle strength was analyzed with a dynamometer simultaneously with the muscle activity of four perishoulder muscles. The data were recorded with surface EMG. Range of motion, muscle strength and activity were evaluated according to the contralateral shoulder at the 24th month of follow-up. RESULTS Male/female ratio was 42/14 with a mean age of 32 years. The mean number of dislocations was 3 ± 1 and all were traumatic dislocations. The number of mean anchors used was 3.1 and the mean follow-up period was 24 months. In clinical evaluation, the preoperative and postoperative results of the DASH and Oxford instability scores of the unstable shoulders were significantly different. In the comparison between the operated and contralateral shoulders, there was no significant difference in DASH and Oxford instability scores at the 24th month of follow-up. There was no significant loss of range of motion. Only internal rotation strength was significantly reduced and there was no significant change in the EMG patterns. CONCLUSIONS Although good clinical results can be achieved, internal rotation strength is reduced after arthroscopic surgery, but daily activities are not affected. There is no guarantee for patients of excellent recovery. LEVEL OF EVIDENCE Level III cohort study.

Abstract
BACKGROUND Neer and Foster's open inferior capsular shift to treat acquired cases of anteroinferior shoulder instability due to an overstretched and redundant capsule is described with good results. Recently, new arthroscopic techniques were described to manage this problem. PURPOSE To assess the results of a new arthroscopic reinforced inferior capsular shift technique based on Neer and Foster's open inferior capsular shift. STUDY DESIGN Case series; Level of evidence, 4. METHODS This new technique of arthroscopic inferior capsular shift was used to treat 108 patients with anteroinferior shoulder instability due to capsular redundancy as confirmed clinically and during arthroscopy. It reduces the size of the redundant capsular pouch and reinforces the thinned-out capsule. Intraoperatively, patients with associated labral tears (n = 25) and patients with open rotator intervals (n = 8) were excluded, and only 75 patients with pure capsular redundancy were included in this study. RESULTS Patients were followed for a minimum of 7 years. All 75 patients had patulous and redundant capsules. Three patients (4.0%) had a redislocation after a significant trauma. The range of motion preoperatively was 168.1° ± 7.5° in forward elevation, 64.7° ± 7.9° in external rotation, and T5.0 ± T0.8 in internal rotation. Postoperatively, it was 167.2° ± 5.8° in forward elevation, 59.95° ± 4.9° in external rotation, and T7.1 ± T1.0 in internal rotation. The American Shoulder and Elbow Surgeons (ASES) (70.76 to 97.53; P < .001), Constant (90.02 to 99.24; P < .001), and University of California, Los Angeles (UCLA) (21.97 to 33.84; P < .001) scores demonstrated significant improvement postoperatively. CONCLUSION This novel technique of arthroscopic capsular shift addresses the problem of capsular redundancy present in many cases of anteroinferior shoulder instability. It tries to achieve a capsular shift based on the principles of Neer. The long-term results are very good.

Abstract
The glenohumeral joint is inherently predisposed to instability by its bony architecture. The incidence of traumatic shoulder instability is 1.7% in the general population. Associated injuries to the capsulolabral structures of the glenohumeral joint have been described and may play a role in predicting recurrent instability. Advanced imaging, computed tomography or MRI may be necessary to adequately evaluate for associated glenohumeral pathology. Treatment algorithms have traditionally included a period of non-operative management in all patients, however young athletic patients may often benefit from early operative treatment. Various open and arthroscopic surgical options exist to address anterior glenohumeral instability. Bony injuries including bony Bankart lesions and Hills Sachs lesion have been implicated in failed surgical management using techniques that address only the soft tissues. An individualized treatment approach, based upon the patient's injury pattern and expectations, will likely lead to the most successful outcome.

Objective preoperative measurement of anterior glenoid bone loss: a pilot study of a computer-based method using unilateral 3-dimensional computed tomography. Arthroscopy 2011; 27:322-9.

Abstract
PURPOSE The purpose of this study was to evaluate the reproducibility of unilateral computed tomography (CT) measurement of glenoid surface area, based on the typically circular geometry of the inferior glenoid. METHODS This study used 3-dimensional shoulder CT scans before reconstruction for anterior instability. The en face CT views of the normal and abnormal glenoids were randomized and evaluated by 3 independent observers (2 experienced shoulder surgeons and 1 medical student). ImageJ (National Institutes of Health, Bethesda, MD) was used to overlay a perfect circle that was fit to the glenoid. The anterior aspect of the circle was then adjusted to match the true anatomic contour of the anterior glenoid. This adjusted region was used to determine the percentage of the perfect circle occupied by the glenoid, which we defined as the anatomic glenoid index (AGI). RESULTS For the 23 normal shoulders, the AGI reflected a nearly perfect fit of the circle, with very high consistency and reliability among the 3 observers. Overall, mean AGI for the normal shoulders was 100.5%, with an SD of 2.2%. For the 12 shoulders that underwent Bankart repair, the overall AGI was 92.1% ± 5.2%, and 9 of 12 patients had an AGI below the threshold of 96.1%. For the 11 shoulders that underwent Latarjet reconstruction, the overall AGI was 89.6% ± 4.7%. CONCLUSIONS This study confirms that the normal inferior glenoid surface is a nearly perfect circle with remarkably low variability. This observation allows for determination of a tight reference range that can be applied to clinical analysis of unilateral CT reconstructions of symptomatic shoulders. This pilot study evaluates a simple and reliable method for determination of the AGI, creating an anatomic preoperative description of bone loss. LEVEL OF EVIDENCE Level III, retrospective comparative study.
