The explosion of carpal tunnel cases in the past few years seems to be related to the increased use of computers and the improper placement of the hands over the keyboard. But what about all those secretaries pouring over typewriters for years, and construction workers using jackhammers eight hours a day, or employees in many other occupations whose wrists are continually bent for long periods of time working numerous types of equipment?

As a common injury seen in litigation, we have chosen several exhibits that will explain the anatomy of the wrist and point out the location of the median nerve in relation to the carpal ligament.

Arteries and Nerves of the Upper Extremity

This highly detailed illustration from the Ciba Collection of Medical Illustrations helps to show the origin of the nerves in the hand. It traces the cervical nerves, which emanate from the brachial plexus as the medial, radial and ulnar nerves, and shows their path to the hand. It serves as a good foundation for the introduction of the specific area of the wrist to follow.

Ligaments of the Wrist

Also from the Ciba Collection, this exhibit gives a detailed view of the specific area where the median nerve passes under the carpal ligament.

Carpal Tunnel Syndrome and Release

From our friends at Medical Visions, this illustration shows the relevant anatomy from both an anterior and cross section view. The full color exhibit is 30x40, laminated, mounted and framed. It can be shipped unmounted on request.

Carpal Tunnel Hand Model

This superbly detailed model allows for demonstration of the nerve as it passes under the carpal ligament. The components are flexible and the carpal ligament can be cut to demonstrate the surgical procedure. This model is an excellent companion to any two-dimensional illustration.
