Abstract
Pronator syndrome is median nerve compression neuropathies at the site where the nerve passes through the pronator teres, to which Seyffarth was the first to draw attention in 1951. Pronator syndrome is very rare and often misdiagnosed as carpal tunnel syndrome. A 36-year-old female patient was referred to our clinics. Initially carpal tunnel syndrome was suspected. But her symptom had shown atypical pattern such as distal interphalangeal joint’s complete paresis of flexion in index finger. We planned carpal tunnel release and exploration of median nerve at proximal forearm simultaneously. Postoperatively we gained complete recovery of hand function free of symptom at last follow-up. It is often difficult to differentiate pronator syndrome from carpal tunnel syndrome. Indeed, these two conditions may coexist(double crush syndrome). If atypical carpal tunnel syndrome is suspected, appropriate diagnosis and treatment should be pursued.
