The acute rupture occurs in collisions when the elbow is in flexion such as that in a wrestling match or a tackle in football. The ulnar collateral ligament distributes over fifty percent of the medial support of the elbow. [16] [17] This can result in an UCL injury or a dislocated elbow causing severe damage to the elbow and the radioulnar joints.
During activities such as overhand baseball pitching, this ligament is subjected to extreme tension, which places the overhand-throwing athlete at risk for injury. [4] Acute or chronic disruption and/or attenuation of the ulnar collateral ligament often result in medial elbow pain, valgus instability, and impaired throwing performance. There ...
During hyperextension the accessory ligaments are lengthened while the proper ligaments are shortened. [3] As a result, the joint is stable during full flexion while the relaxed collateral ligaments allows lateral and rotation movements during extension. [4] The tendons of interosseous and lumbricales add to the lateral stability of the joint. [1]
The composition of the triangular ligamentous structure on the lateral side of the elbow varies widely between individuals [1] and can be considered either a single ligament, [2] in which case multiple distal attachments are generally mentioned and the annular ligament is described separately, or as several separate ligaments, [1] in which case parts of those ligaments are often described as ...
Tommy John surgery (TJS), known in medical practice as ulnar collateral ligament (UCL) reconstruction, is a surgical graft procedure in which the ulnar collateral ligament in the medial elbow is replaced with either a tendon from elsewhere from the patient's own body, or the use of a tendon from the donated tissue from a cadaver.
The ulnar collateral ligament (UCL) can become stretched, frayed, or torn through the repetitive stress of the throwing motion. The risk of injury to the UCL is believed to be extremely high, as the amount of stress through the structure approaches its ultimate tensile strength during a hard throw. [2]
Instead, adult athletes have a fused growth plate, meaning that ligaments and tendons must bear the stress of the repeated throwing motion. A more common injury in adults is to the ulnar collateral ligament of the elbow, an injury that often requires Tommy John surgery in order for the athlete to resume high-level competitive throwing.
