ABSTRACT

Objective: To analyze the clinical effects of reverse shoulder arthroplasty (RSA) for the patients with the cuff tear arthritis(CTA). Methods: A retrospective analysis of 12 patients who had underwent primary RSA for treatment of CTA from January 2012 to June 2017 in Department of Orthopedic, Beijing Chaoyang Hospital, Capital Medical University.

The operation was performed in a conventional manner, the subscapularis and biceps tendon were repaired separately.The preoperative and postoperative American shoulder elbow surgeons score and university of California at LosAngeles score of patients were recorded. The complications and the images of radiological examinations were collected. Data were analyzed by paired-samples t-test. Results: At mean follow-up of (34.7±18.1) months (range3-66 months), the preoperative ASEA score improved from 58.2±8.2 to 92.9±2.9 (t=14.32, P=0.00) and UCLA score improved from 13.2±1.5 to 30.8±1.7(t=23.14, P=0.00). No complications like loosening of prosthesis, superficial wound infection and shoulder dislocation were noted. Conclusion: Reverse shoulder arthroplasty have satisfactory effect for the patients with the cuff tear arthritis.
