Cubital Tunnel Syndrome PatientPlus
Synonym: ulnar neuritis
The ulnar nerve arises from the medial brachial plexus and innervates the muscles of both the forearm and parts of the hand. It also carries sensory neurones supplying the skin of the back of the forearm, the palm and the fourth and little fingers. Most damage to the ulnar nerve occurs at the elbow where it passes through the cubital tunnel. The ulnar nerve may also be damaged:
* At the wrist: due to pressure in Guyon's canal from a deep ganglion, tumour or laceration.
* In the hand: due to compression of the deep motor branch against the pisiform and hamate, such as with prolonged pressure over the outer palm, e.g. motorcyclists and using vibrating drills.
* The elbow is the most common site of compression of the ulnar nerve.
* Cubital tunnel syndrome is the second most common compressive neuropathy (after carpal tunnel syndrome).
* Cubital tunnel syndrome affects men more often than women.
