Ninety-one thumbs with symptomatic trapeziometacarpal arthritis were studied and classified by the severity of trapeziometacarpal arthritis, as seen on the roentgenogram. Thirty-five patients with mild changes had satisfactory relief of pain after treatment with anti-inflammatory drugs and a C-splint. Operation, consisting of resection of the trapezium and shortening by 1.5 cm of the abductor pollicis longus tendon was performed on 16 thumbs. In six patients a rolled palmaris longus tendon was inserted between the metacarpal base and the scaphoid. All patients had relief of pain, improvement of pinch and grip strength, and an increased range of thumb pronation after operation. There was no difference in the results of those patients treated with or without tendon interposition. Trapezial resection was found to be an effective means of treating patients with symptomatic trapeziometacarpal arthritis who failed to improve with conservative care.
