title: Long-term results of cemented Steffee arthroplasty of the thumb metacarpophalangeal joint.
abstract: A retrospective evaluation of the Steffee metacarpophalangeal (MCP) thumb joint prostheses was performed to determine the long-term outcome and survivorship of the prosthesis. Fifty-four primary thumb arthroplasties (49 patients) were performed for pain, weakness, or instability involving the thumb MCP joint secondary to arthritis. Underlying etiology included rheumatoid (49 thumbs), psoriatic (1 thumb), scleroderma (2 thumbs), and degenerative (2 thumbs) arthritis. Thirty-one thumbs had concomitant interphalangeal joint instability and underwent interphalangeal joint fusions. At an average follow-up period of 57 months, the average motion of the MCP joint was 21 degrees (range, 0 degrees to 40 degrees ), with a significant improvement in position and stability. Thumb axis length was maintained or increased in 98%. Although there was not a consistent long-term improvement in grip or pinch strength, 87% of the patients reported subjective improvement in strength and function as a result of surgery. Pain was relieved in all thumbs with preoperative pain. Complications included a periprosthetic fracture, 2 late infections, and 1 gross loosening of the implant. The survivorship of the implant was 93% survivorship at 5 years and 89% survivorship at 10 years, with only 4 failures in 54 thumbs. The Steffee thumb MCP arthroplasty resulted in excellent long-term survivorship, patient satisfaction, and functional outcome.
