The need for Tommy John surgery comes from an injury to the elbow that happens frequently to major league baseball players. Unfortunately, pitches often rupture the ulnar collateral ligament in their elbows. The surgery to correct this injury is named for the first player to receive this operation, Tommy John of the Dodgers in 1974.
