Infraglenoid tubercle avulsion and greater tuberosity fracture resulting from traumatic glenohumeral anterior dislocation: a case report.

Abstract

Traumatic anterior shoulder dislocation can be associated with anteroinferior glenoid bone loss causing potential recurrent instability. We report on a 62-year-old man with a first-time traumatic anterior dislocation of the right shoulder, resulting in both an infraglenoid tubercle triceps avulsion fracture and a greater tuberosity fracture. After reduction, nonsurgical management was chosen. No inferior-oriented apprehension was noticed during follow-up, which might necessitate surgical treatment of the inferior glenoid rim. At latest follow-up, the patient had recovered his shoulder function. Avulsion fractures of the infraglenoid tubercle are uncommon lesions after an anterior shoulder dislocation and, without signs of instability, can be treated conservatively.
