PyroCarbon disk, an innovative approach to interpositional arthroplasty for treatment of CMC arthritis. It is a biarticular convex disc made of PyroCarbon, designed to resurface the thumb carpometacarpal (CMC) joint damaged by arthritis with resultant pain and loss of function. The implant and CMC joint are stabilized by a biologic tendon, transferred and passed through the trapezium, through the implant, and into the first metacarpal. Bone healing to this tendon within the trapezium and the metacarpal give alignment and stability to the implant, which is additionally supported by the prepared concave surfaces of the joint and the convex surfaces of the implant. Goals are pain relief and restoration of motion. As this operation preserves trapezial bone stock, normal thumb length and pinch strength are realistic and achievable goals. Finally, saving the trapezium permits greater choices should revision surgery be indicated.
