The purpose of this study was to evaluate the surgical outcomes of isolated greater tuberosity fractures of the proximal humerus fixed with the spring plates.

Fourteen patients who could be followed up at least 1 year after the surgical treatment of isolated greater tuberosity fracture were evaluated. Their mean age was 51 years (range, 25~73 years). The deltopectoral approach and fixation with the spring plate were performed in all cases. The spring plate was used in all cases. In some circumstances, sutures incorporating the rotator cuff, interfragmentary screw or tension band wire were added. We evaluated the clinical outcomes using UCLA scoring system and KSS (Korean Shoulder Score).

The mean UCLA score was 29.8 and the mean KSS was 89.4. The average time of bony union was 10.2 weeks (range, 7~14 weeks) after the surgery, including 1 case that was performed the secondary operation due to metal failure. The shoulder stiffness were observed in 4 cases and one case of infection was treated well without operation.

In the treatment of isolated greater tuberosity fractures of the proximal humerus, the spring plates fixation can be a good surgical option providing reliable functional results.
