Shoulder Case 11 Background
Fracture of the Greater Tubersoity of the Humerus
Greater tuberosity fractures are commonly seen with comminuted proximal humerus fractures, but isolated greater tuberosity fractures are much less common (19% of all isolated proximal humerus fractures).
They may occur with anterior shoulder dislocations or from an impaction injury. Five to 30% of anterior shoulder dislocations are complicated by greater tuberosity fractures. These fractures are associated with rotator cuff tears, Hill Sachs lesions and nerve injuries (axillary, brachial plexus, median, and ulnar).
