Abstract

[Indexed for MEDLINE] 4. J Am Acad Orthop Surg. 2018 Sep 1;26(17):587-596. doi: 10.5435/JAAOS-D-16-00408. Instability in Reverse Total Shoulder Arthroplasty. Chae J(1), Siljander M, Wiater JM. Author information: (1)From Reid Health, Richmond, IN (Dr. Chae), and Department of Orthopaedic Surgery, Beaumont Health, Royal Oak, MI, and Department of Orthopaedic Surgery, Oakland University William Beaumont School of Medicine, Rochester, MI (Dr. Siljander and Dr. Wiater). Recently, indications for reverse total shoulder arthroplasty have expanded to include glenohumeral arthritis, rotator cuff arthropathy, irreparable rotator cuff tears, complex proximal humerus fractures, sequelae of trauma, and failed shoulder prostheses. Dislocation is a common complication, with rates ranging from 1.5% to 31%. The literature pertaining to management of instability in reverse total shoulder arthroplasty is scanty. Assessment of the patient and biomechanical and surgical factors is critical in determining the best course of treatment. Future studies involving patient selection, prosthetic design, surgical technique, and biomechanics may help reduce the rate of instability. DOI: 10.5435/JAAOS-D-16-00408
