Tendon interposition arthroplasty for degenerative arthritis of the trapeziometacarpal joint of the thumb.
Arthrosis of the trapeziometacarpal joint of the thumb is a predictable sequelae of ligament laxity. A new technique of tendon interposition arthroplasty with ligament reconstruction using the flexor carpi radialis tendon for a painful arthritic trapeziometacarpal joint of the thumb is described. Twenty-one patients had 25 operative procedures; 14 were women and seven were men. All of the patients presented with intractable pain, crepitus, and varying degrees of laxity of the basal joint. Pinch strength was diminished. Follow-up averaged 37 1/2 months. After surgery, 91.7% of patients had good to excellent results, and 56% were completely pain free. Range of motion and grip and pinch strengths were equal on the operated and unoperated sides.
