Pronator syndrome Discussion
Pronator syndrome refers to a disturbance in function of the median nerve
due to some mechanical abnormality at the level of the forearm. This is
most often related to the path normally taken by the nerve through the
middle of the pronator teres muscle, although other areas may be the site
of the difficulty. Pronator syndrome may resemble carpal tunnel syndrome,
but is much less common than carpal tunnel syndrome. Unfortunately, there
is no reliable nerve test to confirm the diagnosis except in cases having
nerve damage. Pronator syndrome is usually treated conservatively, with
surgery to release pressure on the nerve an option for severe cases.
Pronator syndrome may be an explanation for persistent or recurrent
symptoms following surgery for carpal tunnel syndrome, and may be part of a
double crush condition. Outcome following surgery is unpredictable, and
at least one out of three patients have lingering symptoms despite
technically satisfactory surgery.
