title: PyroCarbon implant hemiarthroplasty for trapeziometacarpal arthritis.
abstract: The trapeziometacarpal joint is commonly affected by degenerative arthritis, presenting with pain, stiffness, and swelling at the base of the thumb. When conservative treatment fails, surgical intervention may be warranted based on clinical and radiologic staging as well as patient demand. The concept of replacing the trapeziometacarpal joint remains attractive because of the decreased pain and stiffness, prevention of thumb shortening, and earlier recovery of strength seen with implant arthroplasty. A technique of using a cementless PyroCarbon hemiarthroplasty implant that allows excellent range of motion and decreased postoperative stiffness and pain is presented, with a focus on dorsal capsular reconstruction to prevent subluxation of the implant.
