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.
Note that this ligament is also referred to as the medial collateral ligament [1] and should not be confused with the lateral ulnar collateral ligament (LUCL). [ 2 ] The anterior portion , directed obliquely forward, is attached, above, by its apex, to the front part of the medial epicondyle of the humerus ; and, below, by its broad base to the ...
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.
LOS ANGELES — Throughout Shohei Ohtani's free agency, a question that had gone completely unanswered was the exact nature of the elbow surgery the two-way phenom underwent at the end of the season.
The findings of UCL reconstruction were published in the Journal of Bone and Joint Surgery in 1986. [3] In the four decades since its inception elbow ligament replacement has become common practice for pitchers and players at all levels of baseball, [2] with an estimated one-third of all Major League pitchers in 2014 having undergone it.

In human anatomy, the radial (RCL) and ulnar (UCL) collateral ligaments of the metacarpophalangeal joints (MCP) of the hand are the primary stabilisers of the MCP joints. [1] A collateral ligament flanks each MCP joint - one on either side. Each attaches proximally at the head of the metacarpal bone, and distally at the base of the phalynx.
According to Dr. Jeremy Bruce's research on Ulnar Collateral Ligament Reconstruction shows that it has increased 10-fold in the first decade of the 21st century. [6] [7] He also quoted that due to the trend of UCL injuries continues to be on the rise, athletes aged 14 to 16 are less likely to return to the sport after Tommy John surgery.
