Ulnar Nerve Entrapment eMedicine Orthopedics

Description: Because of the anatomic positioning of the ulnar nerve, it is subject to entrapment and injury by a wide variety of causes. It is the second most common entrapment neuropathy in the upper extremity (the first being the median nerve and its branches). Because of its superficial position at the elbow, it is often injured by excessive pressure in this area (leaning on the elbow during work or while driving a car). This article discusses the most common type of entrapments of the ulnar nerve, which occur most frequently at the elbow and wrist.
