In this article, the authors point out the challenges in managing failed shoulder joint arthroplasty: irreparable rotator cuff deficiency, tuberosity malunion/nonunion, infection and instability. They review their experience with 57 patients having revision of a failed shoulder arthroplasty using a reverse total shoulder.
The types of primary arthroplasties were hemiarthroplasty in 23 (11 for fracture sequelae and 12 for
primary osteoarthritis), total shoulder arthroplasty (TSA) in 13 (for primary osteoarthritis), and reverse shoulder arthroplasty (RSA) in 14 patients (11 for cuff tear arthropathy and three for primary fracture treatment).
The Simple Shoulder Test results demonstrated an improvement from 1.2 to 5.6 points. Complications occurred in 12 cases (24 %), including postoperative hematoma, axillary nerve injury, fracture, and infection with Propionibacterium.
