This study states that The use of reverse total shoulder arthroplasty (RTSA) has spread worldwide as a result of an expansion of indications and an aging society. However, the value of RTSA for very old patients is rarely analyzed. This study was conducted to investigate the outcome of primary RTSA in patients older than 80 years.

We identified 171 shoulders (159 patients) treated with RTSA at an age of more than 80 years between January 2005 and March 2018. The primary outcome parameters were Subjective Shoulder Value (SSV) and the Constant-Murley score, mortality, complications, and reoperation rates. Secondary outcomes were adverse radiographic outcomes. A minimum follow-up of 1 year was accepted in 14 patients (8%) because of these patients’ older age.

We included 171 cases (159 patients; 120 female) with a mean age of 84 ± 3 years (range 80.1-94). The main indication for RTSA was cuff tear arthropathy (43%), isolated rotator cuff tear (22%), and fracture (21%). A total of 136 patients (79%) were eligible for physical examination with a mean follow-up of 41 ± 25 months (12-121).
