Operative treatment of isolated greater tuberosity fractures: retrospective review of clinical and functional outcomes.
Displaced isolated greater tuberosity fractures are rare injuries that require operative treatment to optimize rotator cuff function and prevent painful subacromial impingement. A lack of consensus exists regarding ideal management of these injuries because of the paucity of literature on the subject.The outcomes of 17 patients treated with open (n=15) or arthroscopic (n=2) fixation at the authors' institution between 2001 and 2009 were retrospectively reviewed. Postoperative range of motion, American Shoulder and Elbow Surgeons (ASES) score, visual analog scale (VAS) score, and overall patient satisfaction were recorded at final follow-up. At a mean of 5.2 years (range 1.5-9.7 years), average postoperative active forward elevation was 150.3° (range, 60°-180°), ASES score was 82.9 (range, 46.7-100), and VAS score was 1.4 (range, 0-5). According to Neer's criteria, the overall outcome was excellent in 11 (65%) patients, satisfactory in 5 (29%) patients, and unsatisfactory in 1 (6%) patient. Final postoperative radiographs were available for 15 patients at a mean of 6.64 months. Radiographic union with near-anatomic position of the greater tuberosity was achieved in 13 (87%) of 15 patients. The presence of rotator cuff and rotator interval tears requiring repair, history of dislocation, age 60 years or older, and delayed time to surgery ≥ 10 days did not significantly (P>.05) influence the patients' final active forward elevation and ASES scores.Favorable patient outcomes can be achieved when fractures with >5 mm of displacement are treated with anatomic reduction and secure fixation. For a specific injury, the ideal surgical approach and method of fixation is dictated by patient characteristics and fracture pattern.
