Arthroscopic capsular shift from inferior to superior has an exceptional safety profile and short-term outcomes

ObjectivesArthroscopic Bankart for anterior shoulder instability has a good safety profile but with a relatively high recurrence index. Open surgery has been used to decrease recurrence rates but with a higher complication rate. Arthroscopic capsular shift from inferior to superior (ACSIS) was designed to decrease the recurrence rates without the added morbidity of open surgery. MethodsAn observational retrospective study was conducted to analyze perioperative complications and patient reported outcomes of patients treated with ACSIS to determine the safety profile of the procedure. The patients with anterior traumatic shoulder instability treated with ACSIS between January 2015 and December 2021 were included for the study. The analysis was conducted using SPSS (Version 27). The pre vs. postoperative Western Ontario Shoulder Instability Index scores were compared using a paired sample t-test or Wilcoxon signed ranks test depending on the results of the normality test and Levene's test. The significance level was 0.05 in all analyses. Thirty-six patients were included in this study, the mean age of the population is 30.8 ​± ​11.4 years, with a male dominance of 86.1% (N ​= ​31), and a mean clinical follow-up of 2.7 ​± ​1.2 years. ResultsNo intraoperative complications, including bleeding or neurovascular injury, were noted. Additionally, no early postoperative complications, including infection or hospital readmission, were noted. During the follow-up, one patient (3%) had persistent apprehension. The mean Western Ontario Shoulder Instability index decreased from 66.6 ​± ​13.10% to 27.9 ​± ​22% postoperatively (P ​< ​0.001). ConclusionsACSIS procedure is safe and has good short-term outcomes with a low recurrence rate at 1-year minimum follow-up. Level of Evidence3 (Observational study).

Anterior shoulder dislocation with avulsion fracture of the greater tuberosity results in reliable good outcomes after closed reduction

BackgroundAvulsion of the greater tuberosity (GT) due to traumatic anterior shoulder dislocation (ASD) is a commonly observed fracture pattern. After closed reduction of the dislocated humerus, the greater tuberosity typically reduces itself into its anatomic position enabling the patient to undergo conservative treatment. The aim of this study was to retrospectively review a consecutive series of patients with conservatively treated GT avulsion fractures after closed reduction of an ASD and analyze radiographic outcome, shoulder function and glenohumeral stability and the conversion rate to surgical treatment. Material and methodsAll patients who underwent closed reduction of a GT avulsion fracture after ASD with the primary intention of conservative treatment between 2017 and 2022 were included. Complications (i.e. conversion to surgical treatment), shoulder function assessed with the American Shoulder and Elbow Surgeons (ASES) score and subjective shoulder value (SSV), instability assessed with the Western Ontario Shoulder Instability (WOSI) score, radiological impingement (greater tuberosity index = GTI and impingement index = II) and GT fracture pattern were assessed as outcome measurements. ResultsA total of 29 patients (mean age 44 years, 27% female) with a mean follow-up of 32.6 (range, 8-96) months were enrolled. Seven patients (24%) underwent surgery due to secondary displacement (n=4, 14%) or impingement symptoms (n=3, 10%). All patients who underwent secondary surgery showed a multifragmentary fracture pattern of the GT. Shoulder stiffness (n=7) and neuropraxia of the axillary nerve (n=3) were observed temporarily and resolved during the follow-up period. The ASES and SSV of the conservatively treated patients at the last follow-up was 89.2±19.1 respectively 86±18.2%. No recurrent glenohumeral dislocation was documented. The mean WOSI score at last follow-up was 8(0-71). The mean GTI decreased from 1.2±0.1 after ASD to 1.1±0.1 at the last follow-up (p=0.002). The mean II decreased from 0.6±0.5 after ASD to 0.4±0.3 at the last follow-up (p=0.110). ConclusionThe greater tuberosity avulsion fragment reduces typically into a close to anatomic position after closed reduction and the greater tuberosity index even improves with further conservative treatment over time. Close radiological follow-up is necessary to rule out secondary displacement which occurs typically in a multifragmentary fracture pattern. Patients without the need for surgery showed good clinical outcomes without recurrence of glenohumeral instability.

Clinical Outcomes and Return to Sports After Arthroscopic Repair of Humeral Avulsion of the Glenohumeral Ligament: A Meta-Analysis.

This study aimed to evaluatethe clinical outcomes and the frequency of return to sport after the arthroscopic repair of a humeral avulsion of the inferior glenohumeral ligament (HAGL) lesion.Web of Science, Scopus, and Medline via PubMed and OVID were searched to identify the relevant citations. Screening and data extraction were performed independently. The Comprehensive Meta-Analysis software was used for all statistical analyses (CMA; USA version 3.3.070). A total of 18 articles (n = 832 patients; of whom, 379 patients had HAGL) were included. The fixed-effect estimate showed that the percentage of patients who returned to their sports was 89.1% (95% CI = 85% to 92.2%). The mean duration to return was estimated to be 6.65 months (95% CI = 5.10 to 8.20). Postoperatively, the meanWestern Ontario Shoulder Instability Index (WOSI), Oxford Shoulder Instability Score (OSIS), and Subjective Shoulder Value (SSV) scores were 88.60 (95% CI = 86.18 to 90.98), 15.02 (95% CI = 7.42 to 22.63), and 86.90 (95% CI = 80.79 to 93.00), respectively. The Rowe score improved significantly postoperatively with a mean difference (MD) of54.47 (95% CI = 39.28 to 69.66). The University of California - Los Angeles (UCLA) shoulder score increased significantly post-arthroscopic repair (MD = 10.91, 95% CI = 10.07 to 11.76). The current evidence suggests that arthroscopic repair of HAGL lesions is associated with a high percentage of return to sports and improved Rowe score, WOSI, UCLA shoulder score, OSIS scale, and SSV score. The quality of the included studies is moderate; however, these findings are promising and call for further multicenter, prospective studies.

Return to Play in Adolescent Baseball Players after SLAP Repair (131)

Objectives:Superior labrum from anterior to posterior (SLAP) tears are increasingly common shoulder injuries in adolescent athletes who participate in repetitive overhead throwing. The purpose of this study is to evaluate adolescent baseball athletes who undergo SLAP repair in order to determine their long-term progression of play, surgical outcomes, and overall satisfaction with surgery.Methods:Patients between the ages of 10-19 who underwent a SLAP repair over a 10-year period from 2008-2018 with minimum two year follow-up were identified by a database query in the medical records of a single institution. From this cohort, non-baseball athletes and injuries to non-throwing shoulders were excluded. After identifying the cohort, patients were contacted via phone to complete functional outcome scores including Conway Score, Western Ontario Shoulder Instability (WOSI) Index, Kerlan-Jobe Orthopedic Clinic (KJOC) Shoulder and Elbow Score, Short Form 12 Mental (MCS)/Physical (PCS) survey and a custom return to play questionnaire.Results:During this time period, 59 baseball players met the inclusion criteria for this study and 76.3% (45/59) of patients were available to be contacted to complete final follow-up surveys at a minimum of 2 years. All patients were male with a mean age of 17.4 +/- 1.5 (14-19) years. The mean follow-up of this cohort was 5.3 +/- 2.6 (2.1-12.1) years. The overall return to play rate was 75.6% (34/45). The average time from surgery to initiation of throwing was 5.9 +/- 2.0 (2-12) months and the average time to return to full competition was 11.3 +/- 3.5 (6-22) months after the surgery. After the SLAP repair, those who returned to play continuing playing baseball competitively for 3.0 +/- 1.9 (0.5-8.0) years after surgery. At the time of final follow-up, 71.1% (32/45) of players had stopped playing baseball. Of those who had stopped playing competitive baseball, 12 (37.5%) reported it was because they were not recruited to the next level, 10 (31.3%) reported they lost the desire to play and 10 (31.3%) reported their shoulder prevented them from playing. The overall mean KOJC, WOSI, SF-12 MCS and SF-12 PCS scores were 60.0 +/- 27.4 (range, 0-100), 21.0+/-20.6% (0-73.8%), 55.2+/-3.9 (37.4-59.8) and 55.2+/-5.6 (range, 37.9-65.7) respectively. The overall satisfaction score was 83.2% with 86.7% (39/45) saying they given the opportunity they would undergo surgery again.Conclusions:The results of this study demonstrated a low return to play rate and low patient reported outcomes on baseball specific surveys among adolescent baseball players who underwent a SLAP repair. Mean functional outcome scores between pitchers and position players were not found to be significantly different. Based on these findings, orthopedic surgeons can better counsel their adolescent baseball players on expectations for future return to play and functional outcomes after SLAP repair.

Nonoperative Treatment of Anterior Glenoid Rim Fractures After First-Time Traumatic Anterior Shoulder Dislocation: A Study with 9-Year Follow-up.

Background:Primary traumatic anterior shoulder dislocations can be associated with displaced anterior glenoid rim fractures. Nonoperative treatment of such fractures has been shown to have excellent results in a small cohort of patients; as such, we have been treating these fractures nonoperatively, regardless of fragment size and degree of displacement, provided that post-reduction computed tomography scans revealed an anteroposteriorly centered humeral head. The aim of this study was to analyze the medium- to long-term results of nonoperative treatment of displaced anterior glenoid rim fractures, assessing in particular the residual instability and development of osteoarthritis.Methods:In a 2-center study, 30 patients with a mean age of 48 years (range, 29 to 67 years) were evaluated clinically with use of the Subjective Shoulder Value, Constant score, American Shoulder and Elbow Surgeons score, and Western Ontario Shoulder Instability index, as well as radiographically with use of radiographs and computed tomography scans at a mean follow-up of 9 years (range, 5 to 14 years).Results:Fracture-healing was documented in all patients. Seven patients (23%) had post-fracture onset of osteoarthritis (5 with Samilson grade I and 2 with Samilson grade IV). Of these, 1 patient had recurrent instability that was successfully treated with hemiarthroplasty 9 years after the index injury (relative Constant score, 101%), and was excluded from further analysis. No other patient had a recurrent redislocation, subluxation, or positive apprehension. The other 6 patients with new-onset radiographic osteoarthritis were pain-free (mean Constant score pain scale, 15 points) with good shoulder function (relative Constant score, 84% to 108%). A total of 26 patients (90%) rated their functional outcome as good or very good, and 3 patients (10%) rated it as fair. The mean relative Constant score was 97% (range, 61% to 108%), the mean American Shoulder and Elbow Surgeons score was 92 points (range, 56 to 100 points), and the mean Western Ontario Shoulder Instability index score was 126 points (range, 0 to 660 points). All patients returned to full-time work.Conclusions:Nonoperative treatment of anterior glenoid rim fractures following primary traumatic anterior shoulder dislocation results in excellent clinical outcomes with a very low rate of residual instability and, thus, treatment failure. Asymptomatic radiographic osteoarthritis occurred in roughly 1 of 4 patients.Level of Evidence:Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Arthroscopic versus open Latarjet: a step-by-step comprehensive and systematic review.

To investigate whether arthroscopic Latarjet procedure significantly differs from the open procedure as for the clinical, functional and radiographic outcomes. Two reviewers independently conducted a systematic search according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses using the MEDLINE/PubMed database and the Cochrane Database of Systematic Reviews. These databases were queried with the terms "shoulder" AND "anterior" AND "instability" AND "Latarjet". From the 259 initial papers, we finally assessed five clinical studies which were eligible to our inclusion-exclusion criteria. The mean modified Coleman score for methodological deficiencies of the studies was 65.4/100, whereas it ranged from 53/100 to 77/100. The arthroscopic technique illustrated comparable results to the open technique regarding the postoperative recurrence rate. No significant difference was found amongst groups in relation to the postoperative osteoarthritis, infection rates, soft tissue healing, postoperative mean American Shoulder and Elbow Surgeonsscore, mean Walch-Duplay score, fatty infiltration of the subscapularis muscle and posterior protrusion of the screw. The arthroscopic technique yielded significantly superior results as for the non-union rate of the graft, the total graft osteolysis and graft resorption, the mean Western Ontario Shoulder Instability Index score and the early postoperative pain. Both the open and the arthroscopic Latarjet procedures led to satisfactory radiographic and clinical outcomes for the treatment of patients with recurrent anterior shoulder instability and significant glenoid bone loss. However, the overall quality of the studies ranged from low to moderate. Comprehensive and systematic review of level II-III therapeutic studies.

Open Bankart Repair for the Treatment of Anterior Shoulder Instability without Substantial Osseous Glenoid Defects: Results After a Minimum Follow-up of Twenty Years.

Neglected osseous glenoid defects are thought to be one of the reasons for the reported high rates of recurrent instability at long-term follow-up after Bankart repair. We hypothesized that open Bankart repair for the treatment of anterior glenohumeral instability in the absence of a substantial osseous glenoid defect would result in a lower long-term recurrence rate than has been reported in previous long-term studies. Forty-seven patients were treated with a primary modified open Bankart repair for recurrent anterior shoulder instability between 1989 and 1994. Double-contrast computed tomography scanning was used to exclude patients with a substantial osseous glenoid defect. Forty patients (85.1%) were available for subjective and objective follow-up at a minimum of twenty years (maximum, twenty-five years). Twenty-six patients (65%) underwent clinical examination as well as bilateral shoulder radiography, and fourteen (35%) completed a self-assessment questionnaire and were interviewed by telephone. Seven patients (17.5%) had a recurrence of instability, and six of them had the instability occur after more than eight years without symptoms. The mean Western Ontario Shoulder Instability Index score (and standard deviation) was 256.7 ± 284.8 points; the mean Rowe score, 88.7 ± 12.0 points; and the mean Subjective Shoulder Value, 90.1% ± 10.5%.The mean range of motion of the affected shoulder was decreased by 4° of abduction (p = 0.009), two levels of internal rotation (p = 0.003), 5° of internal rotation in 90° of abduction (p = 0.005), 7° of external rotation in neutral position (p < 0.001), and 7° of external rotation in 90° of abduction (p = 0.004) compared with the contralateral side. The collective instability arthropathy (CIA) index was 0.92 for the affected side and 0.35 for the contralateral side. Open Bankart repair provides good results twenty years after surgery in terms of subjective and objective outcome measurements. However, the long-term failure rate remains high despite the exclusion of substantial osseous glenoid defects. Recurrence of instability seems to be associated with an increased shoulder-specific activity level. Therapeutic Level IV.

Arthroscopic Suture Anchor Fixation of Bony Bankart Lesions: Clinical Outcome, Magnetic Resonance Imaging Results, and Return to Sports

The purpose of this study was to evaluate the outcome, return to sporting activity, and postoperative articular cartilage and bony morphology of shoulders that underwent arthroscopic suture anchor repair of bony Bankart lesions. The inclusion criteria for this retrospective study were anterior glenoid rim fractures after traumatic shoulder instability that were treated with arthroscopic suture anchor repair. Patients were surveyed by a questionnaire including sport-specific outcome, Rowe score, Western Ontario Shoulder Instability Index, and Oxford Instability Score. Three-tesla magnetic resonance imaging could be performed in 30 patients to assess osseous integration, glenoid reconstruction, and signs of osteoarthritis. From November 1999 to April 2010, 81 patients underwent an anterior bony Bankart repair in our department (50 arthroscopic suture anchor repairs, 5 arthroscopic screw fixations, and 26 open repairs). The 55 arthroscopic repairs comprised a consecutive cohort of patients treated by a single surgeon. Of the 50 patients in the suture anchor group, 45 (90%) were available for evaluation. At 82 ± 31 months postoperatively, the mean Rowe score was 85.9 ± 20.5 points, the mean Western Ontario Shoulder Instability Index score was 89.4% ± 14.7%, and the mean Oxford Instability Score was 13.6 ± 5.4 points. Compared with the contralateral shoulder, all scores showed a significantly reduced outcome (P < .001, P < .001, and P < .001, respectively). A redislocation occurred in 3 patients (6.6%). Regarding satisfaction, 35 patients (78%) were very satisfied, 9 (20%) were satisfied, and 1 was partly satisfied. Overall, 95% of patients returned to any sporting activity after surgery. The number of sports disciplines (P < .001), duration (P= .005), level (P= .02), and risk category (P= .013) showed a significant reduction compared with the pretrauma condition. However, only 19% of patients reported that shoulder complaints were the reason for the reduction in activity. Nonunion occurred in 16.6%, with a higher frequency in patients with chronic lesions (P= .031). Anatomic reduction was achieved in 72%, the medial step-off in patients with nonanatomic reduction averaged 1.8 ± 0.9 mm, and the remaining glenoid defect size averaged 6.8% ± 7.3%. Full-thickness cartilage defects of the anterior glenoid were detected in 70% of patients. Arthroscopic suture anchor repair may enable an anatomic reduction of bony Bankart lesions with no or only minimal articular steps and provides successful midterm outcomes concerning clinical scores, recurrence, and patient satisfaction. The return to activity is limited for various, mostly non-shoulder-related causes. Chronic lesions may have an inferior healing potential; therefore early surgical stabilization of acute Bankart fragments is suggested to avoid possible nonunion. Level IV, therapeutic case series.

Redefining “Critical” Bone Loss in Shoulder Instability

Background: Glenoid bone loss is a common finding in association with anterior shoulder instability. This loss has been identified as a predictor of failure after operative stabilization procedures. Historically, 20% to 25% has been accepted as the “critical” cutoff where glenoid bone loss should be addressed in a primary procedure. Few data are available, however, on lesser, “subcritical” amounts of bone loss (below the 20%-25% range) on functional outcomes and failure rates after primary arthroscopic stabilization for shoulder instability. Purpose: To evaluate the effect of glenoid bone loss, especially in subcritical bone loss (below the 20%-25% range), on outcomes assessments and redislocation rates after an isolated arthroscopic Bankart repair for anterior shoulder instability. Study Design: Cohort study; Level of evidence, 3. Methods: Subjects were 72 consecutive anterior instability patients (73 shoulders) who underwent isolated anterior arthroscopic labral repair at a single military institution by 1 of 3 sports medicine fellowship-trained orthopaedic surgeons. Data were collected on demographics, the Western Ontario Shoulder Instability (WOSI) score, Single Assessment Numeric Evaluation (SANE) score, and failure rates. Failure was defined as recurrent dislocation. Glenoid bone loss was calculated via a standardized technique on preoperative imaging. The average bone loss across the group was calculated, and patients were divided into quartiles based on the percentage of glenoid bone loss. Outcomes were analyzed for the entire cohort, between the quartiles, and within each quartile. Outcomes were then further stratified between those sustaining a recurrence versus those who remained stable. Results: The mean age at surgery was 26.3 years (range, 20-42 years), and the mean follow-up was 48.3 months (range, 23-58 months). The cohort was divided into quartiles based on bone loss. Quartile 1 (n = 18) had a mean bone loss of 2.8% (range, 0%-7.1%), quartile 2 (n = 19) had 10.4% (range, 7.3%-13.5%), quartile 3 (n = 18) had 16.1% (range, 13.5%-19.8%), and quartile 4 (n = 18) had 24.5% (range, 20.0%-35.5%). The overall mean WOSI score was 756.8 (range, 0-2097). The mean WOSI score correlated with SANE scores and worsened as bone loss increased in each quartile. There were significant differences (P < .05) between quartile 1 (mean WOSI/SANE, 383.3/62.1) and quartile 2 (mean, 594.0/65.2), between quartile 2 and quartile 3 (mean, 839.5/52.0), and between quartile 3 and quartile 4 (mean, 1187.6/46.1). Additionally, between quartiles 2 and 3 (bone loss, 13.5%), the WOSI score increased to rates consistent with a poor clinical outcome. There was an overall failure rate of 12.3%. The percentage of glenoid bone loss was significantly higher among those repairs that failed versus those that remained stable (24.7% vs 12.8%, P < .01). There was no significant difference in failure rate between quartiles 1, 2, and 3, but there was a significant increase in failure (P < .05) between quartiles 1, 2, and 3 (7.3%) when compared with quartile 4 (27.8%). Notably, even when only those patients who did not sustain a recurrent dislocation were compared, bone loss was predictive of outcome as assessed by the WOSI score, with each quartile’s increasing bone loss predictive of a worse functional outcome. Conclusion: While critical bone loss has yet to be defined for arthroscopic Bankart reconstruction, our data indicate that “critical” bone loss should be lower than the 20% to 25% threshold often cited. In our population with a high level of mandatory activity, bone loss above 13.5% led to a clinically significant decrease in WOSI scores consistent with an unacceptable outcome, even in patients who did not sustain a recurrence of their instability.

Intervention de Latarjet à ciel ouvert pour échec de Bankart Arthroscopique

IntroductionThis retrospective study assessed the functional results of open Latarjet operation for recurrence of instability after arthroscopic Bankart repair in a consecutive series of patients. Patients and methodsFifty-two patients (mean age 28.4 [range 17–62] years, 45 men) were operated on using open Latarjet operation after one (n=46) or two (n=6) failed arthroscopic Bankart repairs. The indication for revision surgery was recurrent dislocation or subluxation. Fifty patients had a Hill-Sachs lesion and 32 patients had glenoid bone lesions on plain radiographs. No attempt was made to grade the severity of bony pathology. Functional outcome and stability of 49 shoulders were assessed after an average follow-up of 38 (range 24–85) months using Western Ontario Shoulder Instability (WOSI) score, Oxford shoulder instability score, and subjective shoulder value (SSV). ResultsForty-two patients had a stable shoulder at follow-up. Seven of 49 (14%) had symptoms of instability; one patient had recurrent dislocation, and six patients had subluxations. Mean WOSI, Oxford, and SSV scores were 83.9, 19.9, and 84.9, respectively. All scores were significantly better in patients who had a stable shoulder compared with those who had an unstable shoulder (WOSI 86.8 vs. 64.3; Oxford 18.2 vs. 30.8; and SSV 88.3 vs. 61.7; P<0.01). One patient needed a reoperation. There were no intraoperative or postoperative complications. ConclusionsOpen Latarjet operation is a good option for failed arthroscopic Bankart repair. The instability recurrence rate is acceptable and the reoperation rate was low. Level of evidenceLevel IV, retrospective case series.

Risk of arthropathy after the Bristow-Latarjet repair: a radiologic and clinical thirty-three to thirty-five years of follow-up of thirty-one shoulders

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. 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. 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). 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.

Arthroscopic Treatment of Multidirectional Shoulder Instability in Athletes

Background There are few reports in the literature detailing the arthroscopic treatment of multidirectional instability of the shoulder. Hypothesis Arthroscopic management of symptomatic multidirectional instability in an athletic population can successfully return athletes to sports with a high rate of success as determined by patient-reported outcome measures. Study Design Case series; Level of evidence, 4. Methods Forty patients (43 shoulders) with multidirectional instability of the shoulder were treated via arthroscopic means and were evaluated at a mean of 33.5 months postoperatively. The mean patient age was 19.1 years (range, 14-39). There were 24 male patients and 16 female patients. Patients were evaluated with the American Shoulder and Elbow Surgeons and Western Ontario Shoulder Instability scoring systems. Stability, strength, and range of motion were also evaluated with patient-reported scales. Results The mean American Shoulder and Elbow Surgeons score postoperatively was 91.4 of 100 (range, 59.9-100). The mean Western Ontario Shoulder Instability postoperative percentage score was 91.1 of 100 (range, 72.9-100). Ninety-one percent of patients had full or satisfactory range of motion, 98% had normal or slightly decreased strength, and 86% were able to return to their sport with little or no limitation. Conclusion Arthroscopic methods can provide an effective treatment for symptomatic multidirectional instability in an athletic population.

Long-term Follow-up of Acute Arthroscopic Bankart Repair for Initial Anterior Shoulder Dislocations in Young Athletes

Background Little is known of the long-term results of acute arthroscopic Bankart repair for first-time traumatic anterior glenohumeral dislocations. Hypothesis Acute arthroscopic Bankart repair for first-time traumatic anterior glenohumeral dislocations will provide good results at long-term follow-up. Study Design Case series; Level of evidence, 4. Methods The authors evaluated a cohort of young patients who sustained first-time anterior glenohumeral dislocations and were acutely treated with arthroscopic Bankart repair using bioabsorbable tacks. Subjective outcome measures were obtained at a mean follow-up of 11.7 years (range, 9.1-13.9 years). Results Thirty-nine patients (40 shoulders) were available of the original cohort of 49 shoulders (82%). Two of the 9 who were lost to follow-up had revision surgery before being lost and are carried forward in the calculations of recurrent instability and revision surgery but are not included in the calculation of the functional scores. The mean Single Assessment Numeric Evaluation was 91.7, the mean Western Ontario Shoulder Instability score was 371.7, the mean subjective Rowe score was 25.3, the mean Simple Shoulder Test was 11.1, the mean American Shoulder and Elbow Society score was 90.9, the mean Short Form-36 Physical Component score was 94.4, and the mean Tegner score was 6.5. Six patients sustained recurrent dislocations for a redislocation rate of 14.3%. Nine patients (21.4%) reported experiencing subluxation events. Six patients (14.3%) underwent revision stabilization surgery. Conclusion At long-term follow-up, acute arthroscopic Bankart repair for first-time traumatic anterior glenohumeral dislocations resulted in excellent subjective function and return to athletics in young, active patients with an acceptable rate of recurrence and reoperation.

Suspension Suture Augmentation for Repair of Coracoclavicular Ligament Disruptions

Surgical reconstruction of the coracoclavicular ligament is a fundamental part of management of high-grade acromioclavicular dislocations and Type II lateral third clavicular fractures. However, no single surgical procedure is fully satisfactory because of failure or complications. We present an alternative coracoclavicular stabilization technique, which avoids the use of hardware or tendon graft, that was used in 10 consecutive patients with complete coracoclavicular ligament disruptions. These patients were followed for a minimum of 14 months (average, 34.8 months; range, 14-55 months). At the final followup, functional outcome measurement instruments (University of California-Los Angeles shoulder rating system and Western Ontario Shoulder Instability Index) and radiographic analysis were adopted as the main outcome measures of shoulder function. The mean University of California-Los Angeles shoulder rating score and the mean Western Ontario Shoulder Instability Index aggregation score at 12 months after surgery were 33.8 (95% confidence interval, 32.8-34.8) and 93.4 (95% confidence interval, 88.2-98.6), respectively. The radiographic analysis revealed all patients had maintained reduction on radiographs at the final followup. These preliminary results suggest that this simple technique can achieve stable coracoclavicular reconstruction and facilitate healing of the repaired ligaments or fractures.

Revision arthroscopic capsulolabral reconstruction for recurrent instability of the shoulder

We have investigated the outcome of arthroscopic revision surgery for recurrent instability of the shoulder after failed primary anterior stabilisation. We identified 40 patients with failed primary open or arthroscopic anterior stabilisation of the shoulder who had been treated by revision arthroscopic capsulolabral reconstruction and followed up for a mean of 36 months (12 to 87). There were 34 men and six women with a mean age of 33.1 years (15 to 48). Details of the patients, the technique of the primary procedure, the operative findings at revision and the clinical outcome were evaluated by reviewing the medical records, physical examination and the use of the Western Ontario shoulder instability index score, the American Shoulder and Elbow Surgeons score and the health status questionnaire 12. Recurrent instability persisted in four patients after the revision arthroscopic procedure. At the final follow-up, the mean American Shoulder and Elbow Surgeons score was 81.1 (17.5 to 99.5) and the mean Western Ontario shoulder instability index score was 68.2 (20 to 98.2). Quality-of-life scoring showed good to excellent results in most patients. Arthroscopic revision capsulolabral reconstruction can provide a satisfactory outcome in selected patients for recurrent instability of the shoulder provided that no large Hill-Sachs lesion is present.

The Modified Bristow Procedure for Anterior Shoulder Instability

Background Many procedures have been proposed for the correction of anterior shoulder instability. Some of these procedures address the problem anatomically, such as the Bankart procedure, and some prevent instability nonanatomically, such as the Bristow-Latarjet procedure. A modified Bristow procedure was the procedure of choice for anterior shoulder instability among midshipmen at the United States Naval Academy from 1975 to 1979. Hypothesis The modified Bristow procedure for anterior shoulder instability provides good shoulder function and stability in the long term. Study Design Case series; Level of evidence, 4. Methods There were 52 shoulders in 49 patients reviewed at a mean follow-up of 26.4 years. The Rowe score, Single Assessment Numeric Evaluation, and Western Ontario Shoulder Instability Index were used to assess outcomes. Results The mean Rowe score was 81.8 (range, 5-100), and the mean Single Assessment Numeric Evaluation score was 82.9 (range, 30-100), with an overall Single Assessment Numeric Evaluation of 71.2% (37 of 52 shoulders) rated as good and excellent. The mean Western Ontario Shoulder Instability Index was 376 of 2100 (range, 0-1560). Overall, recurrent instability occurred in 8 of 52 shoulders (15.4%), with recurrent dislocation in 5 shoulders (9.6%) and recurrent subluxation in 3 shoulders (5.8%). The mean time to recurrent dislocation was 7.0 years. Conclusion This study represents the longest follow-up in the literature of the modified Bristow procedure. The authors have shown nearly 70% good and excellent results and recurrent instability comparable with other long-term follow-up studies of open instability procedures.
