Abstract

The treatment of trapeziometacarpal (TM) osteoarthritis is still debated, as many surgical options are available, and no technique has proven to be superior. Prosthetic treatment in this context has been described since the early 60s. Recently, the use of pyrolytic carbon-based prosthesis has revolutionized arthroplasty surgery in the hand. We performed a retrospective investigation of our surgical management of TM osteoarthritis since 2010 including the study only patients treated with partial trapeziectomy and Pyrodisk implant, with at least 5 years follow-up. After the application of inclusion criteria, 26 patients (6 males and 20 females) were retained. Despite the literature suggesting that implant TM surgery is well suited for older patients, in our experience, the procedure was mainly proposed to the young manual worker, with high demands in terms of thumb strength and stability (mean age of 53 years old, range 37-65). A statistically significant improvement in post-operative DASH, Kapandji and scores was observed. As well, strength measurements, particularly pinch strength and grip strength, increased significantly after the surgery. According to our findings, the Pyrodisk implant provides satisfactory results in terms of thumb strength and stability even in young and active patients and should therefore be considered as a valuable option in selected cases. Meticulous surgical procedure is mandatory in order to avoid complications and should therefore be executed by an expert surgeon. Abbreviation: IV: level of evidence.
