Definition: Cubital tunnel syndrome occurs when the ulnar nerve, one of the primary nerves supplying movement directions to the forearm muscles and sensory information from the hand, becomes compressed near the elbow.
The cubital tunnel is an area through which the ulnar nerve passes; it is formed by bones and ligaments near the elbow. If the cubital tunnel becomes too tight, the ulnar nerve can be compressed, or pinched. When this occurs, muscles of the wrist and hand can become weakened, and numbness and pain of the little and ring fingers may result. Cubital tunnel syndrome can have similar symptoms to golfer's elbow, although the cause is different.
