Abstract

The shoulder’s glenohumeral joint is one of the most often displaced joints in the human body. The most prevalent cause of this painful condition, which has several known origins, is the involuntary contraction of muscles, as in epileptic convulsions, electric shock, or electroconvulsive therapy. To perform a comprehensive analysis of current methods for treating posterior shoulder dislocations that go untreated. The Orthopaedic Surgery Department of Ain Shams University’s School of Medicine performed this meta-analysis and systematic review. Inclusion criteria comprised all research, including patients whose posterior shoulder dislocations had been disregarded. A total of 13 studies reporting the management of neglected posterior shoulder dislocation were selected for this study, which includes a total of 136 shoulders of 133 patients. The management was delayed in all cases for more than 3 weeks, either due to missed diagnosis or delayed patient presentation. The delay time was reported in nine studies, ranging from 1.3 to 16.8 months. Postoperative immobilization in a sling, cast, or brace was advised for 3–8 weeks in 15–30ο abduction with external or neutral rotation. Passive movements were initiated either immediately or within 2–8 weeks postoperatively. Only external rotation and/or pendulum exercises were allowed. Different management processes of posterior shoulder dislocation are effective options for treatment through substantial enhancements in cases comfort, range of motion, and pain management. We still require additional research involving a larger number of cases in order to validate our conclusions
