Ulnar Tunnel Syndrome of the Wrist
Ulnar tunnel syndrome can cause numbness and tingling that is confined to the little finger and along the outside of the ring finger. It is seen more common in women than men, usually occurs between 40-60 years of age.The ulnar nerve, one of the three major nerves supplying the hand, travels through a small space in the elbow, runs in the forearm, and to the heel of hand. It then branches out in the palm and into the ring and little fingers. Excessive compression of the nerve can lead to muscle weakness and lost of feeling in the hands.
