High Index Of Suspicion

The Stener-type lesion of the radial collateral ligament is rare. The insertion of the abductor pollicis brevis is believed to preclude its occurrence. The aim of this study was to determine whether this lesion can be induced mechanically. Four specimens were tested in neutral rotation and 20° of supination, in 45° and 30° of flexion, and in the neutral position. The angle of ulnar adduction to form a Stener-type lesion was measured. The lesion occurred only in 45° flexion in all specimens. A lesser angle of flexion decreased the rate of ligament displacement. In the neutral position no ligament displacement was found. A Stener-type lesion of the radial collateral ligament can occur in ulnar adduction and flexion of the metacarpophalangeal joint. Supination of the joint increases the likelihood of ligament displacement. As distal ruptures of the radial collateral ligament are uncommon, a high index of suspicion is required for diagnosis.

Thumb Metacarpophalangeal Joint

Five cases of chronic instability of the radial collateral ligament of the thumb metacarpophalangeal joint are presented. All patients were treated using the Mitek suture anchor to reattach the avulsed ligament to bone in its anatomical position. Tendon advancement or graft reinforcement was not used in conjunction with the repair. A stable thumb metacarpophalangeal joint was achieved in each case with no recurrent instability or pain found within 9 months of follow-up. Postoperatively, each patient exhibited a full return to activities of daily living within 2 to 3.5 months. Grip and pinch strength and range of motion were nearly the same as in the uninjured hand. We recommend the Mitek suture anchor as a simple and effective method of repairing the chronic radial collateral ligament injury. The importance of correct anatomical placement of the anchor is stressed, and guidelines for this are discussed.
