Fracture dislocation of the glenoid fossa with open physis: a case report.

BACKGROUND

Scapular fractures are uncommon injuries that account for 1% of all fractures. Ten percent of these lesions involve the glenoid fossa and intraarticular displacement is rare, not exceeding 10% of the cases. The classification of intraarticular glenoid fractures was described by Ideberg on the basis of his findings in 100 patients with this type of injury. His classification, however, does not include a dislocation of the glenoid fossa without displacement of the humeral head.

METHODS

We report the case of a fracture dislocation of the glenoid fossa without displacement of the humeral head in a patient with open physis. Our surgical approach and results after 6 years of follow-up.

RESULTS

Six years postoperatively the patient has minimal occasional discomfort and a full range of motion and strength, even in external rotation. Shoulder stability is also normal. Her Constant score is 97. The fracture is actually healed clinically and radiographically with no evidence of post traumatic articular degenerative disease or avascular changes.

CONCLUSIONS

The fracture/dislocation of the glenoid fossa is an uncommon injury that can be effectively treated by open reduction and internal fixation. A posterior surgical approach was useful to achieve anatomic reduction and strong fixation in this case presentation.
