Posterior shoulder dislocation with lesser tuberosity fracture

Case contributed by Dr Bruno Di Muzio

Presentation

First seizure episode.

Patient Data

Age: 58 years
X-ray

Left shoulder radiographs

The humeral head appears rotated and dislocated posteriorly with signs of a comminuted fracture. A linear sclerotic line parallels the humeral head articular surface indicating a reverse Hill-Sachs lesion. 

The humeral head is posteriorly dislocated, has a reverse Hills -Sacs fracture, and a comminuted fracture of its lesser tubercle with a minimal anterior displacement of the fragments. At least two small intra-articular bony loose bodies are noted with no clear donator site; some cortical irregularity present at the posteroinferior margin of the glenoid favours it as one possible site. The remainder of the imaged bones appears intact.

Case Discussion

This case illustrates a posterior shoulder dislocation associated with a reverse Hill-Sachs lesion and a comminuted lesser tuberosity fracture.
