title: Pectoralis major transfer for anterior-superior subluxation in massive rotator cuff insufficiency.
abstract: The purpose of this study was to evaluate the outcome after subcoracoid pectoralis major transfer for anterior-superior shoulder instability in massive rotator cuff insufficiency. Fourteen patients underwent subcoracoid pectoralis major transfer for this debilitating surgical complication. At a mean 17.5-month follow-up, there were 11 satisfactory and 3 unsatisfactory results. Nine of the patients were satisfied with the procedure and would repeat the operation under similar circumstances. Pain scores, as measured on a visual analog scale, decreased from 6.9 to 3.2 postoperatively. Mean forward flexion increased from 24.4 degrees to 60.8 degrees. American Shoulder and Elbow Society functional outcome score increased from 27.2 preoperatively to 47.7 postoperatively. Thirteen of the fourteen patients had improved humeral head containment and improved ability to perform activities of daily living at waist level. A subcoracoid pectoralis major muscle transfer has a low complication rate and is a viable option in this difficult patient population, with better results than those previously reported.
