Cubital tunnel syndrome

Cubital tunnel syndrome is a condition in which the ulnar nerve—better known as the elbow nerve or “funny bone nerve”—becomes compressed in the cubital tunnel on the inner side of the elbow. This nerve runs through a narrow passage behind the bony prominence of the elbow and provides, among other things, sensation and strength to the ring finger and little finger. When the nerve becomes irritated, compressed, or repeatedly stretched, symptoms may occur such as tingling, numbness, pain, or weakness in the hand and fingers. The syndrome is common in people who frequently lean on their elbows, make many bending and straightening movements, or sleep at night with their elbows strongly bent. A good brace or night splint can help reduce pressure on the nerve and support recovery.
