First-time Traumatic Anterior Shoulder Dislocation Research Articles

Advice only versus advice and a physiotherapy programme for acute traumatic anterior shoulder dislocation: the ARTISAN RCT.

The extra benefit of a programme of physiotherapy in addition to advice alone, following first-time traumatic shoulder dislocation, is uncertain. We compared the clinical and cost-effectiveness of a single session of advice with a single session of advice and a programme of physiotherapy. The primary objective was to quantify and draw inferences about observed differences in the Oxford Shoulder Instability Score between the trial treatment groups 6 months post randomisation, in adults with a first-time traumatic shoulder dislocation. A pragmatic, multicentre, superiority, randomised controlled trial with embedded qualitative study. Forty-one hospitals in the UK NHS. Adults with a radiologically confirmed first-time traumatic anterior shoulder dislocation, being managed non-operatively. People with neurovascular complications or bilateral dislocations, and those unable to adhere to trial procedures or unable to attend physiotherapy within 6 weeks of injury, or who had previously been randomised, were excluded. All participants received the same initial shoulder examination followed by advice to aid self-management, lasting up to 1 hour and administered by a physiotherapist (control). Participants randomised to receive an additional programme of physiotherapy were offered sessions lasting for up to 30 minutes, over a maximum duration of 4 months from the date of randomisation (intervention). The primary outcome measure was the Oxford Shoulder Instability Score. This is a self-completed outcome measure containing 12 questions (0-4 points each), with possible scores from 0 (worst function) to 48 (best function). Measurements were collected at 6 weeks, 3 months, 6 months and 12 months by postal questionnaire; 6 months was the primary outcome time point. The primary health outcome for economic evaluation was the quality-adjusted life-year, in accordance with National Institute of Health and Care Excellence guidelines. Between 14 November 2018 and 14 March 2022, 482 participants were randomised to advice (n = 240) or advice and a programme of physiotherapy (n = 242). Participants were 34% female, with a mean age of 45 years, and treatment arms were balanced at baseline. There was not a statistically significant difference in the primary outcome between advice only and advice plus a programme of physiotherapy at 6 months for the primary intention-to-treat adjusted analysis (favours physiotherapy: 1.5, 95% confidence interval -0.3 to 3.5) or at earlier 3-month and 6-week time points on the Oxford Shoulder Instability Score (0-48; higher scores indicate better function). The probability of physiotherapy being cost-effective at a willingness-to-pay threshold of £30,000 was 0.95. We found little difference in the primary outcome or other secondary outcomes. Advice with additional physiotherapy sessions was found likely to be cost-effective. However, small imprecise incremental costs and quality-adjusted life-years raise questions on whether it is the best use of scarce physiotherapy resources given current service demands. Loss to follow-up was 27%; however, the observed standard deviation was much smaller than anticipated. These changes in parameters reduced the number of participants required to observe the planned target difference of four points. Our post hoc sensitivity analysis, accounting for missing data, gives similar results. Further research should be directed towards optimising self-management strategies.

First-time traumatic anterior shoulder dislocation: Approach for the primary health care physician.

Traumatic anterior shoulder dislocation is a very common injury encountered in emergency rooms as well as in the primary health care physician's office. This injury occurs either in the setting of competitive or recreational sports injuries or as a high-energy injury during a fall or a road traffic accident. Common complications such as a recurrent dislocation can be predicted, monitored and prevented. Early appropriate treatment of associated cuff tears or fractures is associated with improved outcomes. There is a plethora of literature on the assessment and management of the primary anterior shoulder dislocation in specialised fields such as sports medicine, orthopaedic surgery and shoulder surgery. These studies are often highly technical, addressed to a particular subset of readers and often deal with one aspect of the management of the injury. This narrative aims to provide the reader with a simplified, evidence-based assessment and management approach for the first-time acute anterior shoulder dislocation. Emphasis is on closed reduction techniques, position and duration of immobilisation, and return to activities of life or sports. Risk factors for recurrence and other indications for primary referral to the orthopaedic surgeon are discussed. Other forms of shoulder instability such as posterior shoulder dislocation, inferior dislocation and multidirectional instability will not be the focus of this narrative.

Labral lesions in first-time traumatic anterior shoulder dislocation: it’s more than just Bankart …

AbstractIntroductionTraumatic anterior shoulder dislocation occurs frequently and usually affects young, active male patients. Detachment of the anteroinferior labrum, known as the Bankart lesion, is a common result. However, more extensive entities including bony lesions and disruptions of the labral ring can also be found. The aim of the present work was to analyze all cases of first-time traumatic anterior shoulder dislocation at a level‑1 trauma center with regard to the type of labral lesion. Focus was placed on the frequency and distribution of complex lesions and the extent of the surgical repair.Patients and methodsThe clinical database of a level‑1 trauma center with a specialized shoulder unit was searched to identify all patients with first-time anterior shoulder dislocation treated between 2015 and 2019. Of 224 patients, 110 underwent primary surgical repair after first-time dislocation (mean age 40 years).ResultsA total of 62% of patients had only a soft tissue injury, while 38% (n = 40) showed a bony Bankart lesion/fracture of the glenoid fossa with a mean defect size of 26%. In only 31% of patients (n = 34), a classicBankart repair was performed, whereas the remaining 69% underwent additional procedures.ConclusionIn this series of surgically treated first-time traumatic anterior shoulder dislocations, the majority of cases presented with more complex lesions than an isolated classic Bankart lesion. The risk for bony involvement and associated pathologies, such as cuff tears and greater tuberosity fracture, increases with age and requires a more extensive surgical approach. Disruption of the labral ring was frequently found in both soft tissue and bony lesions and directly affected the surgical procedure.

Predicting Recurrent Instability of the Shoulder (PRIS): A Valid Tool to Predict Which Patients Will Not Have Repeat Shoulder Instability After First-Time Traumatic Anterior Dislocation.

To assess the sensitivity, specificity, and validity of the Predicting Recurrent Instability of the Shoulder (PRIS) tool in people with a first-time traumatic anterior shoulder dislocation. Prospective cohort study. People with first-time traumatic anterior shoulder dislocation (n = 85), aged 16 to 40 years, were recruited within 12 weeks of their shoulder dislocation and followed prospectively for 1 year post injury. We calculated the sensitivity, specificity, negative predictive value, and positive predictive value of the PRIS tool. Of the 75 participants available for 1-year follow-up, 57 (76%) did not have recurrent shoulder instability. With the PRIS tool cut point set at 0.895, the tool's sensitivity was 39% (95% confidence interval [CI]: 17.3%, 64.3%) and its specificity was 95% (95% CI: 85.4%, 98.9%). The area under the curve was 0.69 (95% CI: 0.55, 0.84; P = .01). The PRIS tool correctly identified 54 of the 57 (95%) who did not have recurrent instability (accuracy, 81%; 95% CI: 70.7%, 89.4%). Negative and positive predictive values were 83% (95% CI: 77.2%, 87.7%) and 70% (95% CI: 40.2%, 89.0%), respectively. The PRIS tool can predict those who will not have further shoulder instability in the year following first-time traumatic anterior shoulder dislocation. The PRIS tool cannot accurately predict those who will have recurrent shoulder instability. J Orthop Sports Phys Ther 2020;50(8):431-437. doi:10.2519/jospt.2020.9284.

Off-track Hill–Sachs lesions predispose to recurrence after nonoperative management of first-time anterior shoulder dislocations

The purpose of this study was to evaluate whether the presence of an off-track Hill-Sachs lesion has an impact on the recurrence rate after nonoperative management of first-time anterior shoulder dislocations. A retrospective cohort study was planned with a follow-up via questionnaire after a minimum of 24months. Fifty four patients were included in the study (mean age: 29.5years; 16 female, 38 male). All of these patients opted for primary nonoperative management after first-time traumatic anterior shoulder dislocation, in some cases even against the clinician's advice. The glenoid track and the Hill-Sachs interval were evaluated in the MRI scans. The clinical outcome was evaluated via a shoulder-specific questionnaire, ASES-Score and Constant Score. Further, patients were asked to report on recurrent dislocation (yes/no), time to recurrent dislocation, pain, feeling of instability and satisfaction with nonoperative management. In 7 (13%) patients, an off-track Hill-Sachs lesion was present, while in 36 (67%) the lesion was on-track and 11 (20%) did not have a structural Hill-Sachs lesion at all. In total, 31 (57%) patients suffered recurrent dislocations. In the off-track group, all shoulders dislocated again (100%), while 21 (58%) in the on-track group and 3 (27%) in the no structural Hill--Sachs lesion group had a recurrent dislocation, p = 0.008. The mean age in the group with a recurrence was 23.7 ± 10.1years, while those patients without recurrent dislocation were 37.4 ± 13.1years old, p < 0.01. The risk for recurrence in patients under 30years of age was higher than in those older than 30years (OR = 12.66, p < 0.001). There were no significant differences between patients with on- and off-track lesions regarding patients' sex, height, weight and time to reduction and glenoid diameter. Off-track patients were younger than on-track patients (24.9 ± 7.3years vs. 29.6 ± 13.6years). However, this difference was not statistically significant. The presence of an off-track Hill-Sachs lesion leads to significantly higher recurrence rates compared to on-track or no structural Hill--Sachs lesions in patients with nonoperative management and should be considered when choosing the right treatment option. Therefore, surgical intervention should be considered in patients with off-track Hill-Sachs lesions. IV.

The immediate and subsequent impact of a first-time traumatic anterior shoulder dislocation in people aged 16-40: Results from a national cohort study.

Limited evidence exists which details changes in quality of life, shoulder activity level, kinesiophobia, shoulder pain and disability following a first-time traumatic anterior shoulder dislocation (FTASD) in people treated non-operatively. This study had three objectives: (1) to examine quality of life, pain, disability and kinesiophobia after an FTASD within 12 weeks, (2) to examine whether these variables were different in people with and without recurrent shoulder instability and (3) to assess how these variables changed over 12 months. A prospective cohort study was undertaken in people with an FTASD aged between 16 and 40 years. Measures of quality of life, kinesiophobia, shoulder activity, shoulder pain and disability were recorded within 12 weeks of an FTASD and at 3, 6, 9 and 12 months. An FTASD negatively impacted quality of life, shoulder pain and function and these variables improved over time. People with recurrent shoulder instability had poorer quality of life 12 months after an FTASD. Across the entire cohort, kinesiophobia did not significantly change across time in people following an FTASD. Quality of life was significantly affected by an FTASD in people with recurrent shoulder instability. Across the entire cohort of people with an FTASD, kinesiophobia remained elevated in people following an FTASD. Level 1 prognostic study.

Treatment of first-time traumatic anterior shoulder dislocation: the UK TASH-D cohort study.

Shoulder dislocations are the most common joint dislocations seen in emergency departments. Most traumatic cases are anterior and cause recurrent dislocations. Management options include surgical and conservative treatments. There is a lack of evidence about which method is most effective after the first traumatic anterior shoulder dislocation (TASD). To produce UK age- and sex-specific incidence rates for TASD. To assess whether or not surgery within 6 months of a first-time TASD decreases re-dislocation rates compared with no surgery. To identify clinical predictors of recurrent dislocation. A population-based cohort study of first-time TASD patients in the UK. An initial validation study and subsequent propensity-score-matched analysis to compare re-dislocation rates between surgery and no surgery after a first-time TASD. Prediction modelling was used to identify potential predictors of recurrent dislocation. UK primary and secondary care data. Patients with a first-time TASD between 1997 and 2015. Stabilisation surgery within 6 months of a first-time TASD (compared with no surgery). Stabilisation surgery within 12 months of a first-time TASD was also carried out as a sensitivity analysis. Re-dislocation rate up to 2 years after the first TASD. Eligible patients were identified from the Clinical Practice Research Datalink (CPRD) (1997-2015). Accuracy of shoulder dislocation coding was internally validated using the CPRD General Practitioner questionnaire service. UK age- and sex-specific incidence rates for TASD were externally validated against rates from the USA and Canada. A propensity-score-matched analysis using linked CPRD and Hospital Episode Statistics (HES) data compared re-dislocation rates for patients aged 16-35 years, comparing surgery with no surgery. Multivariable Cox regression models for predicting re-dislocation were developed for the surgical and non-surgical cohorts. Shoulder dislocation was coded correctly for 89% of cases in the CPRD [95% confidence interval (CI) 83% to 95%], with a 'primary' dislocation confirmed for 76% of cases (95% CI 67% to 85%). Far fewer patients than expected received stabilisation surgery within 6 months of a first TASD, leading to an underpowered study. Around 20% of re-dislocation rates were observed for both surgical and non-surgical patients. The sensitivity analysis at 12 months also showed little difference in re-dislocation rates. Missing data on risk factors limited the value of the prediction modelling; however, younger age, epilepsy and sex (male) were identified as statistically significant predictors of re-dislocation. Far fewer than the expected number of patients had surgery after a first-time TASD, resulting in an underpowered study. This and residual confounding from missing risk factors mean that it is not possible to draw valid conclusions. This study provides, for the first time, UK data on the age- and sex-specific incidence rates for TASD. Most TASD occurs in men, but an unexpected increased incidence was observed in women aged > 50 years. Surgery after a first-time TASD is uncommon in the NHS. Re-dislocation rates for patients receiving surgery after their first TASD are higher than previously expected; however, important residual confounding risk factors were not recorded in NHS primary and secondary care databases, thus preventing useful recommendations. The high incidence of TASD justifies investigation into preventative measures for young men participating in contact sports, as well as investigating the risk factors in women aged > 50 years. A randomised controlled trial would account for key confounders missing from CPRD and HES data. A national TASD registry would allow for a more relevant data capture for this patient group.

Arthroscopic Management of Acute Traumatic Primary Anterior Shoulder Dislocation

AbstractBackground: Glenohumeral joint is the most mobile and most commonly dislocated joint in the human body. The patient's age at the time of injury is inversely related to the incidence of dislocation recurrence rate. Recurrence rate in athletes younger than 20, may be as high as 90%. Arthroscopic stabilization is usually successful in preventing the recurrence of shoulder dislocations leads to reduced recurrence, improved functional outcome.Aim of Study: The aim of this study is to asses the benefits of Bankart repair using suture anchors in treating patient with first time anterior traumatic shoulder instability.Patients and Methods: This prospective study was per-formed on 30 patients having anterior primary shoulder dislocation. All cases were managed by arthroscopic repair of the anterior labral lesion using suture knotted anchors.Results: Patients were assessed pre and post operatively by modified Rowe scale and ASES (American shoulder and Elbow disability system).Conclusion: Primary arthroscopic repair for first-time traumatic anterior shoulder dislocation provided satisfactory functional outcomes and improved quality of life. Primary arthroscopic stabilization can be considered best treatment option in patients younger than 30 years with first time shoulder dislocation.

Management of the First-time Traumatic Anterior Shoulder Dislocation.

Traumatic anterior dislocation of the shoulder is one of the most common directions of instability following a traumatic event. Although the incidence of shoulder dislocation is similar between young and elderly patients, most studies have traditionally focused on young patients due to relatively high rates of recurrent dislocations in this population. However, shoulder dislocations in older patients also require careful evaluation and treatment selection because they can lead to persistent pain and disability due to rotator cuff tears and nerve injuries. This article provides an overview of the nature and pathology of acute primary anterior shoulder dislocation, widely accepted management modalities, and differences in treatment for young and elderly patients.

Do Articular-Sided Partial-Thickness Rotator Cuff Tears After a First-Time Traumatic Anterior Shoulder Dislocation in Young Athletes Influence the Outcome of Surgical Stabilization?

Background:Because of the high risk for redislocations after a first-time traumatic anterior shoulder dislocation with conservative treatment, recent publications have recommended early arthroscopic intervention, especially for young athletes. Concomitant rotator cuff tendon damage may occur when the shoulder dislocates; however, its presence and influence on clinical results have not been well described in this patient category.Hypothesis:In opposition to current opinion, a substantial number of articular-sided partial-thickness rotator cuff tears (APTRCTs) would be found at surgery after a first-time traumatic anterior shoulder dislocation in young athletes. However, the impact of these injuries on 2-year postoperative results would be negligible.Study Design:Cohort study; Level of evidence, 3.Methods:Sixteen male patients (mean age, 21 years [range, 16-25 years]) with a first-time traumatic anterior shoulder dislocation without bony Bankart lesions were included in this study. The indications for surgical treatment were age less than 25 years and being active in collision or contact sports at a competitive level. Arthroscopic surgery was performed at a mean 7.8 days (range, 2-14 days) after injury. Rowe and American Shoulder and Elbow Surgeons (ASES) scores as well as range of motion were evaluated at a minimum 2 years after an arthroscopic Bankart procedure, and a comparison of the clinical results between patients with and without APTRCTs was conducted.Results:An anterior-inferior capsulolabral injury was found in all patients. There were no bony Bankart lesions. An APTRCT was found in 9 of the 16 patients. At 2 years after surgical treatment, there were no significant differences between the patients with and without APTRCTs in terms of the Rowe score (90.0 and 87.1, respectively; P = .69) and ASES score (94.6 and 90.4, respectively; P = .67).Conclusion:APTRCTs were found in the superior part of the shoulder joint after a first-time traumatic anterior shoulder dislocation in a majority of young male athletes treated with surgical stabilization. There were no significant differences found between patients with and without APTRCTs in terms of the Rowe and ASES scores at 2 years after surgical treatment.

The “triple dislocation fracture”: anterior shoulder dislocation with concomitant fracture of the glenoid rim, greater tuberosity and coracoid process—a series of six cases

A combined fracture of the glenoid rim, greater tuberosity, and coracoid process after anterior shoulder dislocation is a rare event. Only 1 patient has been reported in the literature. All patients with a first-time traumatic anterior shoulder dislocation in a level A trauma center were retrospectively reviewed. Among the 2068 patients treated between 1998 and 2013, we identified 6 patients (0.3%; 1 female, 5 male) with "triple dislocation fracture" (anterior shoulder dislocation with concomitant fracture of the glenoid rim, greater tuberosity, and coracoid process). All patients underwent surgery and had computed tomography scans before surgery and the first postoperative day. Mean follow-up time was 59 months. Clinical and radiographic evaluation, Constant-Murley Score, Simple Shoulder Test, and Subjective Shoulder Value were performed at the final follow-up. Surgery was determined individually according to the radiologic findings, patient's age, and personal demands. Glenoid reconstruction was performed in all 6 patients, greater tuberosity refixation in 4 patients, and coracoid process refixation in 3. Two patients needed revision surgery due to loss of reduction. At the final follow-up, mean abduction was 133°, mean anterior flexion was 138°; the mean Constant-Murley Score was 72 points; the mean Simple Shoulder Test was 9 points; and the mean Subjective Shoulder Value was 72%. No recurrent instability occurred. A "triple dislocation fracture," especially coracoid process fractures, can easily be overlooked in radiographs. Computed tomography scans are strongly recommended in patients with a first-time traumatic shoulder dislocation. Because recurrent joint instability and secondary arthropathy are serious complications after anterior shoulder dislocation, surgery should be considered and provides satisfying to excellent results.

Intra-articular lesions and their relation to arthroscopic stabilization failure in young patients with first-time and recurrent shoulder dislocations

This study aimed to compare the frequency of intra-articular lesions between young patients with first-time shoulder dislocations and those with recurrent shoulder dislocations and to assess the correlation between intra-articular lesions and failure of arthroscopic stabilization. The study enrolled 33 patients who underwent arthroscopic Bankart repair after first-time shoulder dislocation before the age of 30 years. There were 89 age-matched patients who were treated arthroscopically for recurrent dislocation included as a control group. Among intra-articular pathologic findings, anterior glenoid erosion (P = .043) and anterior labral periosteal sleeve avulsion lesions (P = .048) were found more frequently in the recurrent dislocation group. There was no statistically significant difference between the 2 groups in American Shoulder and Elbow Surgeons (P = .675) and Rowe (P = .132) scores at the last follow-up. However, there was a significant difference in the failure rate after operation between the 2 groups (P = .039). In the first-time dislocation group, 1 patient had redislocation and none showed positive apprehension. In the recurrent dislocation group, 6 patients had redislocation and 10 patients had positive apprehension. Eight of 10 patients who showed positive apprehension had either anterior labral periosteal sleeve avulsion lesions or anterior glenoid erosion. The patients' satisfaction with daily activities was significantly better in the first-time dislocation group (93.0 ± 5.2) than in the recurrent dislocation group (82.7 ± 7.2; P < .001). Primary surgical treatment for first-time traumatic anterior shoulder dislocation provided satisfactory functional outcomes and improved quality of life. Primary arthroscopic stabilization can be considered one of the treatment options in patients younger than 30 years with first-time shoulder dislocation to prevent further intra-articular injuries that may contribute to recurrence.

The interobserver reliability in diagnosing osseous lesions after first-time anterior shoulder dislocation comparing plain radiographs with computed tomography scans

Recurrence after first-time traumatic anterior shoulder dislocation is frequent. The prevalence of glenoid bone loss ranges from 41% after a first-time dislocation to 86% with recurrent dislocation. Postoperative recurrence can occur in up to 10% of cases. Thus, misdiagnosis of bony glenoid rim lesions has been assumed a major cause for failure. We evaluated the interobserver reliability of radiologic diagnoses after first-time traumatic shoulder dislocation based on radiographs and computed tomography (CT) images. Digital radiographs before and after reduction and CT images after reduction of 20 patients with a first-time shoulder dislocation were assessed by 6 observers. It was recorded whether they diagnosed a lesion at the greater tuberosity, a lesion at the glenoid rim, a Hill-Sachs lesion, or any other skeletal pathology. The average agreement among the investigators was evaluated, and radiographic diagnoses were compared with those based on CT images. Of the 10 cases that presented with a glenoid rim fracture, each investigator had overlooked at least 1 fracture (range, 1-4) on the radiographs. No investigator had diagnosed all 8 Hill-Sachs lesions on the presented images. The average overall agreement among the investigators and corresponding sensitivity and specificity were calculated. Agreement of diagnoses based on radiographs with those based on CT images was lowest for glenoid rim fractures and Hill-Sachs lesions. Radiographs seem inferior to CT scans for assessing osseous lesions especially at the glenoid rim. We suggest performing a CT scan of the shoulder after primary dislocation to apply the correct treatment early and potentially avoid further dislocations.

Paper 31: Arthroscopic Management of First-time Traumatic Anterior Shoulder Dislocation in Young Athletes: Evaluation and Results in 100 Cases with 7.4 years Follow-up

In the literature several publications show the advantages of the early arthroscopic stabilization after the first episode of traumatic shoulder dislocation. Nevertheless it is still considered by some authors a controversial topic. The purpose of this paper is a retrospective evaluation of our first 100 cases treated with arthroscopic stabilization. Between September 1989 and May 2005 100 arthroscopic stabilization of first time dislocation were performed in athletes. Mean age at surgery moment was 22 years. 78% of the patients were rugby players. Until October 1995 we used the Transglenoid suture technique in 23 cases and the others 77 cases were stabilized with Suture Anchor technique. The mean follow-up was 7.4 years (range: 3-19 years). Capsular tear with complete labrum detachment (type III lesion) was the most frequent surgical finding. Minor Bony Bankart lesions (<25%) were found in 19 cases. 75 cases (75%) of osteochondral Hill-Sachs lesions and 15 cases (15%) of bone HillSachs lesions were identified. We treated 2 cases of Humeral Avulsion of Glenohumeral ligament (HAGL) with arhtoscopic and mini open technique. According to the Rowe scale we obtained excellent and good results for 96% (74 cases) of the patients treated with the Suture Anchor Technique and in 87% (20 cases) of the patients treated with the Transglenoid technique. Return to sport was allowed after the 4th month, being at pre-injury level for all cases. The average time was 5.3 months (4-7). Many studies have shown a high percentage of redislocation after non-surgical treatment. Younger patients and practicing contact sports, over head sports or sports of high speed (snow skiing, motocross) increase this risk.

Paper # 22: Clinical Result of Arthroscopic Treatment for First-Time Traumatic Anterior Shoulder Dislocation

Immobilization in External Rotation After Primary Shoulder Dislocation Did Not Reduce the Risk of Recurrence

The treatment of primary traumatic anterior shoulder dislocation varies widely from no immobilization, to two or three weeks of immobilization in internal rotation with the arm in a sling, to treatment with a brace in external rotation. The aim of the present clinical trial was to compare immobilization in internal and external rotation after anterior shoulder dislocation. One hundred and eighty-eight patients with a primary anterior traumatic dislocation of the shoulder were randomly assigned to treatment with immobilization in either internal rotation (ninety-five patients) or external rotation (ninety-three patients) for three weeks. The primary outcome measure was a recurrent dislocation within twenty-four months of follow-up. The follow-up rate after a minimum period of two years was 97.9% (ninety-three of ninety-five) in the internal rotation group and 97.8% (ninety-one of ninety-three) in the external rotation group. The compliance rate with the immobilization was 47.4% (forty-five of ninety-five) in the internal rotation group and 67.7% (sixty-three of ninety-three) in the external rotation group. The intention-to-treat analyses showed that the recurrence rate was 24.7% (twenty-three of ninety-three) in the internal rotation group and 30.8% (twenty-eight of ninety-one) in the external rotation group (p = 0.36). Immobilization in external rotation does not reduce the rate of recurrence for patients with first-time traumatic anterior shoulder dislocation.

Comparison of arthroscopic treatment with conservative treatment for acute first-time traumatic anterior shoulder dislocation in a high-demand population

Abstract Purpose To compare the outcome of primary arthroscopic stabilization with that of nonoperative treatment for acute first-time traumatic anterior shoulder dislocation in a highly active military population at 5- to 7-year follow-up. Methods The patients in this prospective, nonrandomized study comprised 64 highly active military personnel with a first episode of traumatic anterior shoulder dislocation that occurred during the period January 2001 to July 2004. The patients were offered an arthroscopic procedure or nonoperative treatment. The average age was 22 years (range, 17–29 years). A total of 25 patients were treated by nonoperative methods and 39 patients underwent acute arthroscopic repair with metallic suture anchor fixation. Outcome was evaluated based on the Western Ontario Shoulder Instability Index score, the Disabilities of the Arm, Shoulder and Hand score, range of motion, and return to active duty. The mean follow-up was 71 months (range, 60–84 months). Results In the nonoperative group, 92% suffered a redislocation between 5 and 18 months (average, 10 months). In the operative group, only two patients (5.1%) suffered a redislocation 1 year after surgery. There were no surgical complications. In addition, there was no statistical difference in range of motion of injured sites between the two groups. Conclusions Primary arthroscopic stabilization leads to a significantly lower rate of recurrence of shoulder dislocations than nonoperative treatment in high-demand populations. In addition, there is no significant difference of recurrence rate and functional outcome between the surgical group and the nonoperative groups with recurrent dislocation undergoing arthroscopic stabilization at the final follow up.
