Abstract: One of the most commonly injured structures of the thumb metacarpophalangeal (MCP) joint is the ulnar collateral ligament (UCL). An acute injury of this ligament is often amenable to primary repair. Despite the favorable outcomes of primary repair, the thumb is often restricted during initial healing of the ligament with immobilization and delayed rehabilitation.…

Abstract: Medial epicondyle fracture nonunions of the elbow may lead to symptomatic instability in the high-demand or overhead athlete. These injuries are challenging to treat surgically because of the small residual bony fragment, the scarred and shortened chronically injured ulnar collateral ligament (UCL), which prevents it from being mobilized and reduced to its native position.…

Abstract: Purpose: Most elbow dislocations can be treated conservatively, with surgery indicated in special circumstances. Surgical options, apart from fracture fixation, range from repair or reconstruction of the damaged ligaments to static external fixation, usually entailing either a long period of immobilization followed by carefully monitored initiation of movement or dynamic external fixation. In general,…

Abstract: The ulnar collateral ligament (UCL) is the primary restraint to valgus angulation at the elbow. Injury to the UCL is increasingly common and can lead to instability, especially in athletes involved in overhead throwing. Conventional treatment is reconstruction using tendon autograft but performance levels are often restricted after long periods of rehabilitation. Modern surgical…

Abstract: Background: Throwing athletes with ulnar collateral ligament (UCL) injury and symptomatic valgus instability can expect to return to the same or higher level of play. Reconstruction with tendon graft is the dominant method of surgical treatment. Recent evidence suggests that spanning the joint with a suture anchored on both sides is biomechanically equivalent to…

Abstract: Background: Ulnar collateral ligament (UCL) injuries have increased significantly in recent years, and reconstruction has become the preferred treatment for UCL injury over ligament repair. In a recent study, UCL repair with internal bracing demonstrated significantly greater resistance to gap formation in biomechanical tests, even at low cycles of valgus loading…. Read Paper

Background: Current ulnar collateral ligament (UCL) reconstruction techniques are substantially less stiff and demonstrate lower load to failure compared with the native UCL. UCL repair with the addition of an internal brace has demonstrated superior biomechanical performance compared with docking UCL reconstruction, but internal bracing has not yet been used in UCL reconstruction….

Abstract: The anterior bundle of the ulnar collateral ligament (UCL) is the primary restraint to valgus force at the elbow, especially during the arm-cocking and arm-acceleration phases of the overheard throwing cycle. Injuries of the UCL can range from partial thickness tears, end avulsions, to chronic attritional ruptures with poor tissue quality. The incidence of…

Abstract: Background: The number of throwing athletes with ulnar collateral ligament (UCL) injuries has increased recently, with a seemingly exponential increase of such injuries in adolescents. In cases of acute proximal or distal UCL insertion injuries or in partialthickness injuries that do not respond to nonoperative management, UCL repair and augmentation rather than reconstruction may…
