Overview
Ulnar nerve entrapment is a medical condition consequent to the compression of the ulnar nerve along its course. Although compression may occur in the axilla and upper arm, at the elbow, the forearm and the wrist, by far the most common site of entrapment is the elbow.
Ulnar nerve entrapment at the elbow is known as Cubital Tunnel Syndrome. This occurs when the nerve is constricted as it passes through the cubital tunnel on the inside of the elbow.
Common Symptoms
- Numbness and tingling in the ring and little fingers.
- Weakness in the hand and difficulty with finger coordination.
- Muscle wasting (atrophy) in the hand in severe cases.
