How is ulnar entrapment treated?
The ulnar nerve may be entrapped at either the cubital tunnel in the elbow or Guyon’s canal at the wrist.
Avoiding pressure on the nerve at the level of the elbow is achieved by keeping the forearm on the volar side and avoiding rubbing the elbow on hard surfaces.
Repetitive ulnar deviation and flexion at the wrist aggravates the ulnar nerve at Guyon’s canal.
Avoidance of such activities and use of nonsteroidal antiinflammatory drugs (NSAIDs) may help.
Sometimes decompressive surgery is necessary.
