What is it?

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.

Cubital tunnel syndrome symptoms may include numbness or tingling in the ring and small fingers, pain in the forearms and weakness of the hand.

Diagnosis is based upon findings from medical history and physical examination. Further evaluation for cubital tunnel syndrome may include blood tests for diabetes or thyroid disease, and nerve testing. For ulnar tunnel syndrome, imaging and nerve tests may be performed.


Treatment includes avoiding activities that make the pain worse, wrapping a pillow or towel around the elbow at night, physical and occupational therapy. Sometimes, surgery is needed.
