Arthroscopic fixation technique for comminuted, displaced greater tuberosity fracture.
OBJECTIVE
The purpose of this retrospective study was to evaluate the early results of arthroscopic treatment in patients with comminuted, displaced greater tuberosity (GT) fractures using the arthroscopic double-row suture anchor fixation (ADSF) technique.


METHODS
Between August 2004 and December 2007, we used the ADSF technique in 16 cases of isolated comminuted, displaced GT fractures. The early clinical results were evaluated in these patients at a mean of 24 months (range, 16 to 51 months) after surgery. There were 11 male and 5 female patients with a mean age of 56.5 years (range, 27 to 82 years). These 16 cases had at least 5 mm of displacement of the fracture fragments in any plane. For measurement of clinical outcomes, we assessed range of motion and evaluated the visual analog scale score; the University of California, Los Angeles (UCLA) rating scale; and the shoulder index of the American Shoulder and Elbow Surgeons.


RESULTS
At final follow-up, the visual analog scale score improved from 9.4 (range, 8 to 10 points) to 1.2 (range, 0 to 4 points), the mean UCLA score improved to 31 points (range, 21 to 35 points) postoperatively, and the American Shoulder and Elbow Surgeons score improved to 88.1 points (range, 81.5 to 100 points). According to the UCLA score, there were 3 excellent results, 11 good results, and 2 poor results. Mean forward flexion was 148.7 degrees (range, 120 degrees to 170 degrees), mean abduction was 145 degrees (range, 120 degrees to 170 degrees), mean external rotation in the neutral position was 24 degrees (range, 10 degrees to 40 degrees), and internal rotation improved to the first lumbar vertebral level (from L3 to T7) at last follow-up.


CONCLUSIONS
The early results of the ADSF technique used for displaced, comminuted GT fractures are encouraging, and arthroscopists should attempt to expand the indications for arthroscopic treatment of these fractures.
