Neuromuscular examination of the hand and wrist indicates Ulnar nerve dysfunction. There may be weakness of wrist and hand flexion and difficulty moving the fingers. A detailed history may be needed to determine the possible cause of the neuropathy. Tests are guided by the suspected cause of the dysfunction, as suggested by the history, symptoms presented, and pattern of symptom development. They may include various blood tests, X-rays, scans, or other tests and procedures.
Treatment is aimed at maximizing use of the hand and arm.
The cause should be identified and treated as appropriate. In some cases, no treatment is required and recovery is spontaneous. If there is no history of trauma to the area, conservative treatment is indicated by sudden onset, minimal sensation changes and no difficulty in movement, and the absence of test results indicating degeneration of the nerve axon. Corticosteroids injected into the area may reduce swelling and pressure on the nerve. Surgical intervention is indicated if the disorder is chronic or symptoms are worsening, if there is difficulty with movement, or if there is evidence that degeneration of the nerve axon is present.
