Abstract:
Total joint arthroplasty is a promising surgical treatment for painful thumb trapeziometacarpal osteoarthritis. Strict surgical technique is essential to achieve a reliably good outcome. Preoperative radiographic evaluation before surgery and intraoperative fluoroscopy during surgery are valuable means of optimizing implant positioning. This article provides an overview of how to perform proper radiographic evaluation for trapeziometacarpal arthroplasty, and discusses radiographic guidelines for correct implant placement and how to use them during surgery.
