Posterior Shoulder Dislocation Associated With Fracture Of T
Posterior shoulder dislocation associated with fracture of the acromion is a rare injury with only three cases published in literature. Up to 79% of posterior shoulder dislocations can be missed with 65% of patients having associated complications. We present a case of posterior shoulder dislocation associated with fracture of the acromion and describe the mechanism of injury, diagnosis, and management.

Case Report
28-year-old male presented to the Emergency Department intoxicated, with pain localised over the left shoulder following a fall. The patient had sustained a direct impact to the anterior aspect of the left shoulder. On clinical examination, there was generalised tenderness over the left shoulder with reduced range of movement. Antero-posterior radiographs revealed a displaced transverse acromion fracture and a posterior shoulder dislocation that was not initially detected by the Emergency Department physician. (Figure 1). The patient was referred the on call orthopaedic team and the dislocation was reduced under sedation in the Emergency Department. He was investigated further with cross-sectional imaging and MR revealed a glenohumeral hemarthrosis, and reverse Hill Sach's lesion with a reverse Bankart's lesion. The rotator cuff was intact. There was a displaced fracture of acromion with marked osseous and soft tissue oedema (Figures 2 & 3). The patient was initially managed conservatively with sling immobilisation and physiotherapy for four weeks. Unfortunately, the patient was lost to follow-up.

Really it is a rare mode of injury also. otherwise common causes of posterior dislocation are electric shot or fits.
