Carpal tunnel syndrome (CTS) is a nerve compression syndrome associated with the collected signs and symptoms of compression of the median nerve at the carpal tunnel in the wrist. Carpal tunnel syndrome usually has no known cause, but there are environmental and medical risk factors associated with the condition. [1] [6] CTS can affect both wrists.
More than three million patients seek medical attention every year for nerve-related disorders such as sciatica, carpal tunnel syndrome or various other nerve injuries, yet before 1992, no radiologists were trained to image nerves. [5] There are two main physical bases for the imaging discovery.
Carpal tunnel as seen on MRI. The carpal bones that make up the wrist form an arch which is convex on the dorsal side of the hand and concave on the palmar side. The groove on the palmar side, the sulcus carpi, is covered by the flexor retinaculum, a rigid band of fibrous tissue, thus forming the carpal tunnel.
Carpal tunnel surgery is usually considered after other treatment options have failed, Melamed says. Other, less invasive treatments, like splinting and steroid injections, are typically tried first.
