Treatment options for locked posterior shoulder dislocations and clinical outcomes

Abstract

▪Posterior dislocations are rare and diagnostically difficult injuries. Diagnosis is often delayed and this leads to a locked posteriorly dislocated humeral head. ▪Treatment options include conservative methods and surgical anatomic reconstruction options as well as nonanatomic surgical procedures such as subscapularis tendon transfer, hemiarthroplasty and total shoulder arthroplasty. ▪Decision-making for treatment as well as prognosis depend on the extent of the articular defect size of the humeral head, duration of the dislocation and patientspecific conditions such as age and activity levels.
