This audit summarizes the first 100 consecutive shoulder arthroplasties performed by a single surgeon between 2013-2016. It found: 1) The majority of procedures were for osteoarthritis or cuff tear arthropathy. The proportion of revisions is increasing. 2) Outcomes were comparable to national joint registry data, with reverse replacements being more common than anatomical replacements. 3) Complication rates were lower than literature reports, with 3 periprosthetic fractures, 2 dislocations, and 1 acromial stress fracture being the main surgical complications.
