What are sportscasters talking about when they say a baseball player has had "Tommy John surgery?"

In medical terminology, it is called "ulnar collateral ligament reconstruction," and it is reconstruction of the ligament around the elbow. Tommy John was a former Chicago White Sox pitcher who was the first to undergo this surgical process in 1974. Before the surgery was developed the injury ended a player's career. The surgery has been refined and improved since 1974.
