Pyrolytic carbon arthroplasty for the proximal interphalangeal joint: results after minimum 3 years of follow-up.

A retrospective study was undertaken to review the outcomes of a consecutive series of patients treated using pyrocarbon surface replacement arthroplasty by the same surgeon. We analyzed the results of this procedure in 24 proximal interphalangeal (PIP) joints in 19 hands of 16 patients. The minimum follow-up was 3 years. The study showed that pyrocarbon PIP joint replacements provided excellent pain relief and high patient satisfaction. More than two-thirds of patients subjectively rated postoperative range of motion and functional outcomes as better than preoperatively. Objective assessment showed a modest improvement in the active range of motion, which did not achieve statistical significance, although we did observe a statistically significant increase in passive range of motion. The results are encouraging for those surgeons who seek an alternative to silicone implant PIP joint arthroplasty in high-demand patients.
