A prospective study was undertaken to assess the outcomes of a series of patients treated using pyrocarbon implant arthroplasty after partial trapeziectomy for trapeziometacarpal joint osteoarthritis. We analysed the results of this procedure in 27 trapeziometacarpal joints of 25 patients. The mean follow-up interval was 34 months (range 26-52). The study showed that pyrocarbon interpositional arthroplasty provided excellent pain relief and high patient satisfaction. Overall function, according to disabilities of the arm, shoulder and hand (DASH) score, improved from 48 points preoperatively to 14 points at the last follow-up assessment. Key pinch strength recorded in the operated hands was comparable with the results obtained in the contralateral hand and in healthy individuals from the same population. No further operations were performed in the study group. Partial trapeziectomy with pyrocarbon arthroplasty may prove to be a successful option for the treatment of trapeziometacarpal joint osteoarthritis. Further long-term comparative studies are warranted.
