title: Treatment of chronic injuries of the ulnar collateral ligament of the thumb using a free tendon graft and bone suture anchors.
abstract: We report the results of a simple technique, using bone suture anchors and free tendon graft, for the reconstruction of chronic injuries of the ulnar collateral ligament complex at the thumb metacarpophalangeal (MP) joint. Our series includes 20 patients, with a mean age of 29 years. The mean follow-up period was 42 months. Using the Glickel grading system, 14 patients had excellent results and six had good results. Seventeen patients had no pain and three complained of mild pain with weather changes. Fourteen patients regained full stability of the MP joint and six had mild laxity. The mean loss of pinch strength was 18% compared with the contralateral thumb. The mean loss of motion at the metacarpophalangeal joint was 21%.
