Purpose:
Arthritis of the carpometacarpal joint of the thumb is common, and there are many studies regarding its treatment. We investigated the long-term outcome of interposition arthroplasty with a fascia lata allograft (pillow technique), without ligament reconstruction, to treat thumb carpometacarpal arthritis. The technique consisted of complete trapeziectomy, use of alloplastic tensor fascia lata, and K-wire immobilization for 5 weeks.
Methods:
The outcomes of 31 thumbs in 24 female patients were measured at a mean follow-up of 12.5 years (range, 10-15 years).
Results:
Grip strength, key pinch, pulp-to-pulp pinch, tripod pinch, and range of motion were all improved. The Disabilities of the Arm, Shoulder, and Hand median score, which was only measured postoperatively, was an average of 5 (range, 0-52.6). No extrusion of the graft material was noted, and no revisions were performed.
Conclusions:
Our results indicate that a fascia lata allograft can be used as an interposition material in thumb carpometacarpal arthroplasty. This technique provides pain relief and satisfactory function at an average of 12.5 years after surgery.
Type Of Study/Level Of Evidence:
Therapeutic IV.
