Bilateral anterior shoulder dislocation as a result of manipulation: A case report

Bilateral Anterior Shoulder Dislocation: A Systematic Review

Objectives

To compile the existing literature on bilateral anterior shoulder dislocation (BASD) and analyze patient demographics, mechanisms of injury, injury characteristics, management, and outcome.

Methods

This systematic review was conducted in accordance with Preferred Reporting Items for Systematic review and Meta-Analyses (PRISMA) guidelines. Online databases, including Ovid Medline 1946-, Embase.com 1947-, Scopus 1960-, Cochrane Central, and Clinicaltrials.gov were systematically queried. Studies eligible for inclusion were case reports or case-series, documenting BASD. Two reviewers independently screened and applied a set of a priori exclusion criteria to each returned study. Data were extracted, compiled, and synthesized from each reported case of BASD. Contingency tables/Chi-Square Analyses, T-tests, and univariate regression analyses were conducted to assess relationships between different variables.

Results

Eighty-one studies (87 cases of BASD) were included. Patients were 41.1 (SD± 19.5) years old and most were male (n=63; 72.4%). Around a quarter of patients (28.7%) had a history of epilepsy/seizures or were being worked-up for such. Younger males were more likely to have BASD due to a seizure or electrocution (P<0.05). Close to a third of cases (n=27; 31.0%) were delayed in presentation. Those sustaining seizures or electrocutions were more likely to be delayed in presentation (P=0.013). Most events resulted in simple dislocations that were closed reduced successfully. BASD resulting from seizures or electrocutions were more likely to be fracture-dislocations (P=0.018); and in younger patients with fracture-dislocations, closed reduction was more often to fail or not be attempted (P<0.05). Median follow-up was 6 months (IQR: 3 months - 12 months). Seven patients (10.6%) had complications and 4 (2.3%) demonstrated recurrent instability.

Conclusion

In young males presenting with BASD without known trauma, suspicion should be high for a convulsant event. In patients with a known seizure disorder who present with chronic bilateral shoulder or arm pain, BASD should be considered and work-up should be expedited to avoid misdiagnosis.

Shoulder Injury Following Overzealous Manipulation in Adhesive Capsulitis by Untrained Professional Managed with Shoulder Arthroscopy

Introduction

Adhesive capsulitis of shoulder is a commoner condition in middle aged population and is classified into primary and secondary types based on etiology. Treatment options depend on stages of disease which ranges from physical therapy, non-steroidal anti-inflammatory medications, intra-articular steroid injection, hydro-dilatation therapy, manipulation under anesthesia, and arthroscopic capsular release. However, the condition is generally mismanaged by untrained professionals in the periphery center leading to complications. We report one such case, which was then managed arthroscopically.

Case Report

A 58-year-old female patient presented to our outpatient department with a severe painful left shoulder following overzealous manipulation by untrained professional and she was diagnosed with severe traumatic capsulosynovitis with a subscapularis tear, biceps tendon subluxation, and shoulder subluxation. We managed patient arthroscopically with extensive capsulosynovectomy, biceps tenotomy, and upper subscapularis repair. Postoperatively, she was immobilized for 6 weeks and was put on proper rehabilitation program. At the 2-year follow-up, the patient had an excellent outcome and had complete pain-free movements at the left shoulder with significant increase in pre-operative constant shoulder score of 12-82.

Conclusion

?Overzealous manipulation shoulder in frozen shoulder patients has serious complications and has to be avoided and therefore has to be done by trained professional gently under anesthesia. Shoulder arthroscopy plays a pivotal role in managing such complications successfully.
