Cubital Tunnel Syndrome is due to the compression of the ulnar nerve around the back of the elbow. This results in numbness of the little and ring fingers and weakness and wasting of the hand muscles. These symptoms are often worse during activities when the elbow is bent and at night-time. Cubital Tunnel Syndrome is often caused by repetitive motion and overuse activities as well as, repetitive trauma to the back of the elbow.
For mild cases, a nighttime splint that prevents elbow bending will help to reduce the symptoms. For more severe cases, an operation, which "decompresses" the ulnar nerve, is required. This operation is usually performed under general anaesthesia as a daycare procedure.
