Diagnosis and Treatment of Work-Related Ulnar Neuropathy at the Elbow

Abstract Ulnar neuropathy at the elbow (UNE) is the second most common entrapment neuropathy after carpal tunnel syndrome and occurs most commonly at the elbow due to mechanical forces that produce traction or ischemia to the nerve. The primary symptom associated with UNE is diminished sensation or dysesthesias in the fourth or fifth digits, often coupled with pain in the proximal medial aspect of the elbow. Treatment may be conservative or surgical, but optimal management remains controversial. Surgery should include exploration of the ulnar nerve throughout its course around the elbow and release of all compressive structures.
