1 UCL Injury Stories

The ulnar collateral ligament (UCL) of the elbow is part of the complex of ligaments and tendons that attach and stabilize the bones of the lower and upper arm where they meet at the elbow joint. UCL injuries are also often called Tommy John injuries, named after the famed Major League Baseball player Tommy John who, in 1976, became the first person to return to play at the professional level after experiencing a complete tear of his ulnar collateral ligament.
