Ulnar neuropathy is a disorder involving the ulnar nerve. Ulnar neuropathy may be caused by entrapment of the ulnar nerve with resultant numbness and tingling. It may also cause weakness or and paralysis of the muscles supplied by the nerve. Signs and symptoms
In terms of the signs/symptoms of ulnar neuropathy trauma and pressure to the arm and wrist, especially the elbow, the medial side of the wrist, and other sites close to the course of the ulnar nerve are of interest in this condition. Many people complain of sensory changes in the fourth and fifth digits. Rarely, an individual actually notices that the unusual sensations are mainly in the medial side of the ring finger (fourth digit). Sometimes the third digit is also involved, especially on the ulnar (medial) side. The sensory changes can be a feeling of numbness or a tingling, pain rarely occurs in the hand. Complaints of pain tend to be more common in the arm, up to and including the elbow area, which is probably the most common site of pain in an ulnar neuropathy. Causes
Among the causes of ulnar neuropathy are the following-

Much more commonly, ulnar neuropathy is caused by overuse of the triceps muscle and repetitive stress combined with poor ergonomics. Overused and hypertonic triceps muscle causes inflammation in the tendon and adhesions with the connective tissue surrounding that tendon and muscle. These in turn impinge on or trap the ulnar nerve.
