Definition

Ulnar neuropathy is an inflammation or compression of the ulnar nerve, resulting in paresthesia (numbness, tingling, and pain) in the outer side of the arm and hand near the little finger.

Description

The ulnar nerve transmits impulses to muscles in the forearm and hand. The nerve is responsible for the proper sensing of touch, texture, and temperature throughout the fourth and fifth digits of the hand, the palm, and the underside of the forearm. Ulnar neuropathy arises most commonly because of damage to the nerve as it passes through the wrist. The elbow is also a frequent site of nerve damage. Ulnar neuropathy is variously known as bicycler's neuropathy, cubital tunnel syndrome, Guyon or Guyon's canal syndrome, and tardy ulnar palsy.

Demographics

Ulnar neuropathy that originates at the elbow is very common....
