Abstract:
Reverse shoulder arthroplasty (RSA) was proposed to deal with rotator cuff tear arthropathy in the 1970s and improved from 1985 to 1995 by Dr. Grammont who designed the contemporary type of reverse shoulder prosthesis successfully. The number of RSAs has grown rapidly over the past decade. Currently, the indications for RSA include, in addition to rotator cuff tear arthropathy, massive rotator cuff tears which can not be repaired, proximal humerus fractures or their sequelae, inflammatory shoulder disease, osteoarthritis with abnormal glenoid morphology, anatomic revision after failed total shoulder arthroplasty or hemiarthroplasty, and shoulder tumors. Absolute contraindications to RSA include infection, complete axillary nerve palsy, neuropathic shoulder arthropathy, and glenoid bone loss. At present, the stability of the glenoid baseplate, an important factor affecting the incidence of postoperative complications, is mainly achieved by implantation of the screws for the glenoid baseplate base. Therefore, correct implantation of the screws is of great significance to reduce the complications in RSA.
