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.

Introduction Digital collateral ligament injuries are common hand injuries that can cause significant pain and functional impairment. Ultrasonography can be useful in the evaluation of these ligamentous injuries, as it is both cost-effective and allows for easy, dynamic evaluation during imaging. Case report We report a rare sonographic finding of an index finger radial collateral ligament injury that was found to have a flap of the ligament entrapped within the metacarpophalangeal joint, which to our knowledge has not been described previously. We correlate this finding with an intraoperative image of the entrapment of the collateral ligament. We also report on the novel application of superb microvascular imaging to aid in the diagnosis of digital collateral ligament injury. Discussion This particular injury pattern has not been reported in the literature previously and likely explains the patient’s lack of improvement with nonoperative management. Our finding is similar to a Stener lesion seen in a thumb ulnar collateral ligament injury in which the ligament is unable to heal due to entrapment. In addition, using superb microvascular imaging (SMI), we were able to visualize hyperemia to surrounding structures and the ligament itself which suggested an acute injury. Conclusion We anticipate that this case report will provide sonographers with knowledge and images of this specific injury pattern to the digital collateral ligaments.
