Early outcomes of Pyrocardan implants for trapeziometacarpal osteoarthritis.

The aim of this retrospective study was to assess the early outcomes of trapeziometacarpal osteoarthritis treatment using Pyrocardan implants in patients with early Eaton (stage I and II) osteoarthritis. We analyzed the results of 27 patients, with a median age of 59 years (range, 34-78 years) and a mean follow-up of 24 months (range, 12-41). The level of satisfaction was assessed using a postoperative questionnaire. Twenty patients mentioned having improvements in their activities of daily living, 20 patients were satisfied with the outcomes of surgery, and 19 patients would consider undergoing the procedure a second time. Five patients needed reoperation for complications, including persistent pain, grinding, or implant dislocation. Pyrocardan implants may be a valuable temporary therapy as more conventional arthroplasty techniques are still feasible in case of failure. However, multicenter randomized controlled trials with a longer follow-up are needed to assess the long-term outcomes.
