Glenoid Fossa Fracture: (Image submitted by Dr. George Kochman)
Fractures of the glenoid fossa occur when the head of the humerus collides with the glenoid margin; classically, by a laterally directed force. Although less than 10% of glenoid fossa fractures result in significant displacement, surgical repair is indicated if:
- Fracture displacement >10mm
- >33% involvement of posterior glenoid fossa
- >25% involvement of anterior glenoid fossa
- Persistent humeral head subluxation
