OverviewSymptomsTreatmentPrevention

Distal median nerve dysfunction

Alternative Names:

Neuropathy - distal median nerve

Carpal tunnel syndrome



Treatment:

Treatment is aimed at correcting the underlying cause. In most cases, isolated median nerve dysfunction is due to entrapment or injury. In this case, identifying the site of entrapment is best done with EMG or in some cases, X-rays and MRI scans. If an entrapment is confirmed, medications and even surgery may be helpful, depending on the site of entrapment and severity of nerve injury.

If the median nerve is affected by carpal tunnel syndrome, a wrist splint can reduce further injury to the nerve and help alleviate symptoms. In some cases, no treatment is required and recovery is spontaneous. Over-the-counter or prescription analgesics may be needed to control nerve pain (neuralgia).

If other nerves are also affected, it is necessary to look for an underlying medical problem that can affect nerves. Medical conditions like diabetes, kidney disease and others can damage nerves. In these cases, treatment is directed at treating the underlying medical condition.

Physical therapy exercises may be appropriate for some persons to maintain muscle strength. Orthopedic assistance may maximize the ability to use the hand. This may include use of braces, splints, or other appliances. Vocational counseling, occupational therapy, occupational changes, job retraining, or similar interventions may be recommended.



Expectations (prognosis):
If the cause of the nerve dysfunction can be identified and successfully treated, there is a possibility of full recovery. In some cases, there may be partial or complete loss of movement or sensation. Nerve pain may be severe and persist for a prolonged period of time.

Complications:
  • Partial or complete loss of hand movement
  • Partial or complete loss of sensation in the fingers
  • Recurrent or unnoticed injury to the hand


Calling your health care provider:
Call your health care provider if symptoms of distal median nerve dysfunction are present. Early diagnosis and treatment increase the chance of controlling symptoms.
