J Am Acad Orthop Surg, Vol 19, No 7, July 2011 Emilie Cheung, MD, Matthew Willis, MD, Matthew Walker, MD, Rachel Clark and Mark A. Frankle, MD Reverse total shoulder arthroplasty was initially used to manage complex shoulder problems. Indications have been expanded to include rotator cuff arthropathy, massive rotator cuff tear, failed shoulder arthroplasty, and fracture sequelae. Increased use of primary reverse total shoulder arthroplasty has led to reports of associated problems unique to the procedure. The most common complications include neurologic injury, periprosthetic fracture, hematoma, infection, scapular notching, dislocation, mechanical baseplate failure, and acromial fracture. Little information has been published regarding best practices for managing these complications.
