Anatomical Snuffbox: Structure and Function
Overview
The anatomical snuffbox is a small triangular depression located on the radial aspect of the dorsum of the hand. It is formed by the tendons of the extensor pollicis longus and extensor pollicis brevis muscles. This structure is easily visible when the thumb is extended away from the hand.Structure
The anatomical snuffbox is bound by the tendons of the abductor pollicis longus and extensor pollicis brevis muscles on the ulnar side, and the tendon of the extensor pollicis longus muscle on the radial side. The floor of the snuffbox is formed by the scaphoid and trapezium bones of the wrist.Function
The anatomical snuffbox serves as an important landmark for locating the radial artery, which runs through the anatomical snuffbox on its way to the hand. This structure is also utilized for specific clinical examinations, such as the Finkelstein test for diagnosing de Quervain's tenosynovitis.Clinical Significance
Injuries to the tendons or bones within the anatomical snuffbox can result in pain, limited range of motion, and functional impairments. It is crucial for healthcare providers to be aware of the anatomy of this area to accurately diagnose and treat conditions affecting the hand and wrist.Anatomical snuffbox Examples
