Neuropathy – ulnar nerve; Ulnar nerve palsy
Definition of Ulnar nerve dysfunction
Ulnar nerve dysfunction is a problem with the ulnar nerve, which travels from the shoulder to the hand and allows movement or sensation in the wrist or hand.
Causes, incidence, and risk factors
Damage to one nerve group, such as the ulnar nerve, is called a mononeuropathy. Mononeuropathy means there is nerve damage to a single nerve. Both local and body-wide disorders may damage just one nerve.
Signs and tests
A careful history of when the problem started and what you might have been doing that could have injured the nerve is important.
The goal of treatment is to allow you to use the hand and arm as much as possible. The cause should be identified and treated. Sometimes, no treatment is needed and you will get better on your own.
If the cause of the dysfunction can be found and successfully treated, there is a good chance of a full recovery. In some cases, there may be partial or complete loss of movement or sensation. Nerve pain may be severe and last for a long period of time.
