General

The ulnar nerve is a nerve that passes from the axillary area to the hand through a groove in the inner side of the elbow. Cubital tunnel syndrome refers to pressure or stretching of the ulnar nerve, which may cause numbness or tingling in the ring and small fingers, pain in the forearms and weakness of the hand. Ulnar tunnel syndrome refers to compression of the ulnar nerve as it passes to the hand through the Guyon’s tunnel and causes numbness, pain or tingling of the wrist.
