Minimally invasive trocar-assisted reduction of an acute locked multifragmentary posterior fracture-dislocation of the proximal humerus without internal fixation: a case report

Traumatic posterior glenohumeral dislocations are relatively uncommon orthopaedic injuries and are frequently overlooked at initial presentation. However, they are associated with a high incidence of concomitant osseous and/or soft tissue injuries. Early recognition and appropriate management of a posterior (fracture-)dislocation of the proximal humerus are essential to limit morbidity. Nevertheless, evidence-based treatment protocols are currently lacking.
