Cubital tunnel refers to a tunnel at the elbow through which the ulnar nerve (funny bone nerve) travels. It carries sensations from the small finger and adjacent part of ring finger as well as the back of the hand to the brain. It also carries signals that cause contraction of several muscles in the hand.

 

Cubital tunnel syndrome refers to a group of symptoms resulting from pressure on the ulnar nerve at the elbow: numbness and tingling of small finger and ulnar side of ring finger; symptoms get worse on bending the elbow. As the condition progresses muscle of the hand become weak and later atrophy and the small and ring fingers start clawing (see Fig 3, 4). For More Information: Cubital tunnel syndrome
