BERTONA ALTIERI, Bernardo A et al. Resultados a corto plazo de la prótesis invertida de hombro según la patología. Rev. Asoc. Argent. Ortop. Traumatol. [online]. 2017, vol.82, n.4, pp.278-286. ISSN 1852-7434.

Objective: 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, 85 reverse shoulder arthroplasties were performed. Surgical indications included: rotator cuff tear artropathy, glenohumeral osteoarthritis, proximal humeral fractures and revision arthroplasty. Patients were clinically and radiologically evaluated and analyzed in different groups. Results: The mean follow-up was 42 months (range 26-60) and the mean age was 74.5 years (range 56-90). Constant score improved from 16.7 to 62.1 on average (p<.001) while ASES score improved from 12.7 to 68.8 on average (p<.001). Elevation increased from 80.5° to 111.5° (p<.001). There was no significant improvement in internal and external rotation. Sixty patients (78.9%) were very satisfied/satisfied. A total of 22 patients (27.8%) had notches in the inferior rim of the glenoid. Complication rate was 20%, being more frequent in the group of fractures and revision arthroplasties. Conclusions: 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 a valid alternative in multiple shoulder conditions; however, complication rate is high, so the indication should be accurate, especially in patients treated for fractures or in revision surgeries.
