Presentation
First seizure episode.
Patient Data
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 favors 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.
