title: Partial arthroscopic trapeziectomy with ligament reconstruction to treat primary thumb basal joint osteoarthritis.
abstract: Since the outcome of partial trapeziectomy is not always satisfactory, we proposed using arthroscopy to perform partial trapeziectomy and to perform ligament reconstruction with the abductor pollicis longus tendon. A tendon strip was left intact at its insertion at the base of the first metacarpal and then slipped into the trapeziectomy space. It was fixed into a blind tunnel at the base of the second metacarpal with a bioabsorbable interference screw. Forty-nine patients were surgically treated between 2006 and 2009. With an average follow-up of 3.6 years, 83.5% of patients were satisfied with the procedure; 96% of thumbs were stable and 74% were pain free. The average recovery time was 4.5 months. There were four cases of radial nerve branch irritation and one case of flexor carpi radialis tendinitis; there were no cases of complex regional pain syndrome. This minimally-invasive technique is a less-aggressive treatment approach for thumb carpometacarpal joint arthritis, which simplify postoperative recovery.
