When this condition (referred to as a Stener lesion) occurs, the adequate healing of the tear is prevented altogether. For a Stener lesion to occur, a complete tear of the ulnar collateral ligament must be present. However, the Stener lesion can occur even in the absence of a tear of the accessory collateral ligament or volar plate.
Ulnar collateral ligament reconstruction, colloquially known as Tommy John surgery, is a surgical graft procedure where the ulnar collateral ligament in the medial elbow is replaced with either a tendon from elsewhere in the patient's body, or with one from a deceased donor.
Due to the relation between their insertions on the sides of the metacarpal head and the axis of rotation in the joint, the collateral ligaments are taut in flexion but lax in extension, while the accessory collateral ligaments are lax in flexion but taut in extension. [1]
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 ...
The Ligament Advanced Reinforcement (LARS) is a leading artificial ligament in ACL repair surgery. They are made of polyethylene terephthalate (PET). [3] They consist of an intraosseous and an intra-articular portion. The intraosseous section consists of longitudinal fibers bounded by a knitted transverse structure.

A sprain is a soft tissue injury of the ligaments within a joint, often caused by a sudden movement abruptly forcing the joint to exceed its functional range of motion.. Ligaments are tough, inelastic fibers made of collagen that connect two or more bones to form a joint and are important for joint stability and proprioception, which is the body's sense of limb position and movem
The injury is often associated with an experience of a sharp “pop” in the elbow, followed by pain during a single throw. [2] In addition, swelling and bruising of the elbow, loss of elbow range of motion, and a sudden decrease in throwing velocity are all common symptoms of a UCL injury. If the injury is less severe, pain can alleviate with ...
