In this article we will discuss about Anatomical snuff box. So let’s get started.
Anatomical snuff box
It is a small triangular depression present on the dorsal and lateral (radial) aspect of hand. It’s medial boundary is formed by extensor pollicis longus, lateral boundary by extensor pollicis brevis and abductor pollicis longus, proximal border by styloid process of radius and distal border is formed by merging of lateral and medial border forming isosceles triangle. It’s floor is made by scaphoid and trapezium bone. It is innervated by the radial nerve, artery supply is through the radial artery and venous supply is through the cephalic vein. Clinically it is a common site for FOOSH injury(fall on outstretched hand).
