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.
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.
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 are both non-surgical and surgical treatment options. [5]

That's because Ohtani is recovering from an injured elbow ligament — the ulnar collateral ligament — that often leads to a procedure colloquially known as Tommy John surgery. Ohtani has been ...
Type Ia: thin; lax when the elbow is extended and becomes taut when the elbow is flexed. Type Ib: thick; taut even when the elbow is not fully flexed (90°–120°). Under both definitions, Osborne's ligament forms the roof of the cubital tunnel, an opening between the muscles through which the ulnar nerve passes. [citation needed]

Olecranon fracture is a fracture of the bony portion of the elbow. The injury is fairly common and often occurs following a fall or direct trauma to the elbow. The olecranon is the proximal extremity of the ulna which is articulated with the humerus bone and constitutes a part of the elbow articulation. Its location makes it vulnerable to ...
