Transplant of the teres major in the treatment of irreparable injuries of the rotator cuff (long-term analysis of results).
Purpose of this study is to evaluate the effectiveness of muscle transfer of the teres major in the treatment of irreparable posterosuperior injuries of the rotator cuff. Long-term monitoring of the results obtained in 20 patients treated at our clinic using this method are reported, comparing the data obtained in evaluations of results with preoperative values. Clinical evaluations were obtained using the Constant Score System, while X-ray examination showed the presence of osteoarticular modifications, and MRI and electromyography the preserved morphology and function of transplant. The mean Constant Score increased from 31.6 points preoperatively to 66.1 points postoperatively at the time of follow-up. At follow-up, MRI allowed us to evaluate any fatty degeneration of the muscle fibers of transfer and the integrity of tendinous insertion on the humeral greater tuberosity. The obtained results allowed us to reveal the advantages and the disadvantages of teres major transplant in irreparable posterosuperior ruptures of the cuff.
