A novel hybrid fixation technique for osteosynthesis of isolated greater tuberosity fractures of the proximal humerus

Isolated fractures of the greater tuberosity (GT) are common. Both cadaveric and clinical studies have indicated that only 5 mm of displacement can lead to poor functional outcomes secondary to rotator cuff imbalance and subacromial impingement. Multiple techniques have been described for operative fixation of isolated GT fractures; however, inherent problems exist with each technique. The purpose of this study is to describe a novel open surgical technique for isolated GT fractures that combines cancellous screw and suture anchor fixation. The benefits include a complimentary biomechanical construct that provides rigid fixation in both comminuted and noncomminuted fracture patterns to allow early rehabilitation while minimizing hardware failure and subsequent malunion.
