Cubital tunnel syndrome is a set of symptoms caused by abnormal pressure on the ulnar nerve. The nerve passes through the cubital tunnel on the inside of the elbow. Problems with this nerve can cause a weak hand grip and numbness in the ring and small finger.
Pressure on the ulnar nerve can cause problems in the hand and fingers.
