Ulnar Nerve Disorders PatientPlus

Description: Causes of ulnar nerve disorders
* Ulnar nerve can be damaged by dislocation or fracture dislocation of the elbow and can be compressed by those who habitually lean on their elbows.
* May be associated with medial epicondylitis (golfer's elbow).
* Nerve can become entrapped in the cubital tunnel of the elbow during heavy manual work or following a previous poorly healed supracondylar fracture of the humerus or due to osteophytic encroachment in osteoarthritis.
* Causes of compression of the ulnar nerve at the wrist include aneurysm of the ulnar artery, thrombosis, synovial inflammation and ganglia, or by repeated trauma at work.
