Short-term results of shoulder reversal prosthesis according to pathology.

Abstract

Purpose The purpose of this study is to analyze the short term functional results and complications of the reverse shoulder prosthesis according to different etiologies. Methods Between 2009 and 2013 we performed 85 reverse shoulder arthroplasties. Surgical indications included: Rotator cuff tear artropathy, glenohumeral osteoarthritis, proximal humeral fractures and revision arthroplasty. The patients were clinically and radiologically evaluated and analyzed in different groups. Results The mean follow-up was 42 months (26-60) and the mean age 74.5 years (56-90). The Constant improved from 16.7 to 62.1 on average (P <.001) and the ASES, from 12.7 to 68.8 on average (P <.001). The elevation increased from 80.5 ° to 111.5 ° (P <.001). There was no significant improvement in internal and external rotation. Sixty patients (78.9%) reported being very satisfied / satisfied. In 22 patients (27.8%) they were found notches in the inferior rim of the glenoid. The complication rate was 20%, being more frequent in the group of fractures and revision arthroplasties. Conclusion The reverse shoulder arthroplasty significantly improved functional scores, anterior flexion and abduction, regardless of surgical indication. It has limitations with respect to the external and internal rotation postoperatively. It is valid alternative in multiple shoulder pathologies, however has a high rate of complications, so the indication should be accurate, especially in patients treated for fractures or revision surgeries.
