Anatomical collateral ligament reconstruction in the hand using intraosseous suture anchors and a free tendon graft

Abstract

We describe anatomical collateral ligament reconstruction using a free tendon graft and intraosseous suture anchors in the digits. Eleven patients who underwent collateral ligament reconstruction at the proximal interphalangeal or metacarpophalangeal joints were enrolled in this study. Proper and accessory collateral ligaments were reconstructed using a free tendon graft in an anatomical configuration and the grafted tendons were fixed with suture anchors. The mean time from surgery to last follow-up was 9.2 months. All anchors used for fixation of grafted tendons remained securely at their original positions at the last follow-up visits. No significant complications were associated with the use of anchors. Clinical results were excellent in 10 patients and good in one. Anatomical reconstruction of collateral ligaments using suture anchors is simpler, faster, and safer than the conventional bone tunnel technique and it does not have the risks of breakage of bone bridges, skin irritation, or graft loosening.
