Reconstruction of chronic collateral ligament injuries to fingers by use of suture anchors.

AIM To evaluate the effectiveness of suture anchors in the reconstruction of chronic collateral ligaments of fingers. METHODS We treated 8 patients, 6 with chronic instability of the collateral ligament of the thumb and 2 with the instability of the fifth finger, using the Statak suture anchor. A stable joint was achieved in each case, with no recurrent instability or pain within a mean of 14 months of the follow up. RESULTS Postoperatively, each patient returned to his or her original job, their daily activities, and sports. There was no significant difference on manual stress testing measurements between operated and uninjured fingers. Mean pinch strength and range of motion were 90% (range, 78-104%) and 94% (range, 70-100%), respectively, compared to uninjured fingers. CONCLUSION Suture anchor technique can be recommended as a simple and effective method of repairing the collateral ligament of fingers.
