Abstract
This is a report of a case of the pronator syndrome which relapsed three times and was operated on four times.
Case: A 70 year old female with a complaint of paresthesia in the median nerve region and muscle weakness in the right index finger. A positive Tinel's sign at both proximal forearm and wrist were elicited and a nerve conduction test revealed the slowing of conduction velocity in the forearm and prolongation of distal motor latency across the carpal tunnel. The patient was diagnosed as having both the pronator syndrome and the carpal tunnel syndrome. A release operation for the median nerve was performed June 1996, and symptoms remitted, but, recurred two months later, the nerve having been compressed by the exostosis of the radius. This tumor was resected February 1997 and again symptoms remitted, recurred four months later. July 1997, the operation to release the nerve compressed by the pronator teres muscle was performed and symptons disappeared, but recurred 21 months later, the nerve having been compressed by the osteochondroma of the ulna which was resected April 1999. To date, the patient has been free from symptoms for more than 7 months.
