In occupations that require repetitive wrist movements, change in the way the job is performed may be necessary. There may be weakness of the thumb and difficulty with opposition of the thumb and little finger. 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 independence and ability to function at work and home.
The cause should be identified and treated as appropriate. In some cases, no treatment is required and recovery is spontaneous. Corticosteroids injected into the area may reduce swelling and pressure on the nerve in some cases. Surgical decompression may be recommended if the symptoms are caused by entrapment of the nerve. Surgical removal of lesions that press on the nerve may benefit some cases.
