Introduction
The shoulder is the most frequently dislocated joint in the human body.1 There are three main types of dislocations regarding the direction of the humeral head displacement: anterior; inferior; and posterior. Anterior shoulder dislocation is the most common type while inferior dislocation is the rarest, making up to 95% and 1%, respectively. Posterior dislocations are rare and diagnostically difficult injuries. Diagnosis is often delayed because of subtle radiological findings and this results as a posteriorly locked humeral head. Due to the low number of the patients with locked posterior shoulder dislocations, there is not a large patient cohort and it is not possible to conclude an evidence-based treatment strategy from the literature. In this review article, posterior shoulder dislocation, its treatment options and its clinical results are discussed to determine the best available treatment strategy according to the pathology and injury mechanism.
