Of 77 total shoulder-replacement arthroplasties with a Neer prosthesis, I evaluated 73 replacements in 65 patients at 2 to 6 and one-half years after the operation. The operations were performed for the treatment of osteoarthritis, rheumatoid arthritis, and old fractures or fracture-dislocations with traumatic arthritis. Postoperatively there was little or no pain even with vigorous activities in most shoulders, and active abduction improved by an average of 44 degrees, to an average of 120 degrees. The amount of abduction that was regained was related to the original diagnosis and to the amount of rotator cuff disease. Complications developed in 13 shoulders, and 5 reoperations were necessary. 8 glenoid components showed radiographic evidence of loosening. 52 of the remaining 65 shoulders had some radiolucency at the glenoid bone-cement junction.
