The UCL, or ulnar collateral. ligament, is located in. the middle thumb joint, and provides support to. the thumb during grip. and pinch. It is the most. common ligament injury.
The ulnar nerve passes through the cubital tunnel which is a bony passageway. When you hit your funny bone and have tingling in the small and ring fingers, you are hitting the ulnar nerve at the cubital tunnel. The ulnar nerve controls muscles primarily of the little, ring, and sometimes middle fingers. It also controls muscles in the hand used for strong pinch, and other muscles that coordinate fine movements. Symptoms may primarily involve numbness and tingling in the little and ring fingers, the side and back of the hand.
