ABSTRACT
PURPOSE:
To demonstrate that silicone metacarpophalangeal (MCP) arthroplasty provides excellent long-term outcomes with a low complication rate in osteoarthritis patients.METHODS:
A consecutive cohort of 35 patients with osteoarthritis of 1 or more MCP joints undergoing anatomically neutral silicone MCP arthroplasty was followed over a 15-year period. Functional outcomes including strength and range of motion (ROM), as well as complications, were recorded. All patients were available for long-term assessment including radiographs and outcomes questionnaire.RESULTS:
Average follow-up for the cohort of 35 patients (40 implants) was 8.3 years (range, 2-17 years). Average age was 58 years (range, 42-80 years) with 22 men and 13 women. In 31 patients, a single MCP joint was involved (middle finger, 20; index finger, 10; little finger, 1). The dominant hand was involved in 23 patients. Seven (of 14) patients had a concomitant RCL reconstruction of the index finger MCP joint; no other digit had a collateral ligament reconstruction. Average final visual analog scale pain score was 0.3 of 10. Average final active ROM arc was from 4° (range, 0°-20°) to 73° (range, 50°-90°) of flexion. One patient had a revision MCP arthroplasty for a 97% clinical survivorship. Radiographs demonstrated fractured implants in 5 of 40 (12.5%) implants, but none exhibited instability, pain, or ROM deterioration. Average Michigan Hand Outcomes Questionnaire score was 82 (of 100) at final follow-up.CONCLUSIONS:
Silicone arthroplasty is effective in the treatment of primary MCP osteoarthritis. Implant survivorship is 97% (clinical) and 88% (radiographic) in long-term follow-up. TYPE OF STUDY/LEVEL OF EVIDENCE Therapeutic IV.Palabras clave
