Arthroscopic Partial Trapeziectomy and Interposition Arthroplasty of the Thumb Carpometacarpal Joint

Abstract

Trapeziometacarpal arthritis, a common and disabling condition, often is treated by open procedures involving trapeziectomy and interposition arthroplasty. A minimally invasive technique potentially could offer advantages over more common open procedures. We describe an arthroscopic technique for the treatment of trapeziometacarpal arthritis. After adequate arthroscopic debridement, interposition arthroplasty may be performed with a variety of materials.
