Radial tunnel syndrome discussion
Radial tunnel syndrome refers to irritation of the radial nerve in the
forearm. It may result in an aching pain in the forearm, and pain or
numbness on the back of the hand, behind the thumb. It is usually
spontaneous, but may arise in association with local trauma, inflammation
or tumor. Onset of symptoms may be gradual or abrupt, and there may be
weakness of the muscles which straighten the fingers and thumb. Symptoms
may be aggravated by use, but there is no clear evidence that use of the
hands causes radial tunnel syndrome. Nerve studies may or may not confirm
the diagnosis. If there is no evidence of nerve damage, initial treatment
options are conservative, with antiinflammatory medication, vitamin B6 and
Neurontin or similar medication. Painful activities are avoided for
comfort. Surgery to take pressure off the nerve may be considered after
three months of plateau of symptoms. On the average, about seven out of ten
patients are improved following surgery. Chances of persistent problems are
greater in older patients, those with long standing symptoms, those with a
compensation related diagnosis, or in the context of metabolic or multiple
level nerve irritation.
