"Anatomical Snuff Box" - This feature can be seen by abducting the thumb as far as possible. Such action will produce a small depression at the lateral aspect of the wrist on its posterior side. On the cadaver, extend a superficial incision along the lateral edge of the first metacarpal following the superficial radial nerve as a guide. Create a small flap of skin by which to gain access to the area.
This space is formed by the tendinous extensions of the abductor pollicis longus and extensor pollicis brevis, laterally, and the extensor pollicis longus, medially.
The floor of the snuffbox is formaed by the scaphoid bone of the wrist. With removal of the superficial fat and fascia in the space, the passing of the radial artery in the space can be seen.
