Thumb carpometacarpal osteoarthritis is one of the most common problems in hand surgery practice. This common disease produces pain, aggravation of insufficient motion, joint instability, swelling, tenderness and crepitus, resulting in significant disability in daily living. Various surgical procedures have been developed such as simple trapeziectomy, arthrodesis, ligament reconstruction tendon arthroplasy, and implant arthroplasty. The goal is to perform the best operation in order to restore strength, range of motion, and painless function. We performed Watson's procedure on 11 patients. This technique is a modification of the Burton's procedure, which is based on three components: suspension of the thumb metacarpal on the flexor carpi radialis tendon through dorso-radial to palmarulnar insertion, maintenance of the cortical bridge at the base of the metacarpal, and interposition of a tight collagenous (tendon) arthroplasty. All patients acquired satisfactory pain relief, pinch power, grip strength, and range of motion.
