Ulnar Collateral Ligament Repair With Suture Bridge Augmentation

Abstract

The gold standard for management of elbow ulnar collateral ligament (UCL) injuries in elite athletes is reconstruction of the UCL with a tendon graft. Over the past several years, UCL repair for acute tears, as well as partial tears, in young athletes has gained increasing popularity, with studies reporting good outcomes and high rates of return to sports. Additionally, there is increased interest in ligament augmentation using the InternalBrace concept. A recent technique paper describes a direct repair of the UCL augmented with a spanning suture bridge. Although clinical outcomes for this method are promising, one possible concern when using this technique is bone loss at the ulnar origin of the UCL should revision reconstruction be required. We propose an alternative augmentation method that allows for stress shielding of the healing native ligament while minimizing bone compromise in the face of UCL reconstruction at a later time point.
