Work-related Carpal Tunnel Syndrome

Carpal Tunnel Syndrome (CTS) involves compression of the median nerve at the wrist. The finger tendons, blood vessels and median nerve extend from the forearm to the fingers through a small tunnel (surrounded by bone) in the wrist, named the carpal tunnel. If any of the tendons in the carpal tunnel become swollen, the median nerve is pinched resulting in pain, numbness and tingling of the first three fingers of the hand. If CTS is not treated in its early stages, it can result in permanent disability. It is estimated that close to 1 million people in the United States annually may develop CTS, requiring medical care and leaving them at least temporarily disabled.
