The anatomical snuffbox is a triangular deepening on dorsoradial aspect of the hand at the level of the carpal bones. [See image below]
The name originates from use of this space for snuffing tobacco powder.
Anatomically, the tendon of extensor pollicis longus forms the posterior border
Anterior border is formed by extensor pollicis brevis and the abductor pollicis longus.
The styloid process of the radius forms proximal border and the apex of the triangle formed by anterior and posterior border.
Trapezium and the scaphoid can be palpated in the floor of the snuffbox.
The radius and scaphoid articulate deep to the snuffbox to form the basis of the wrist joint. A tenderness in this area should arouse suspicion of scaphoid fracture.
