The tenderness in the anatomical box indicates fracture of scaphoid bone. The cephalic vein at this site is often used for giving intravenous uids. The supercial branches of the radial nerve can be rolled over the tendon of extensor pollicis longus.Anatomical Snuff Box Anatomical Snuffbox is a triangular depression on the lateral aspect of wrist immediately distal to the radial styloid process,that becomes prominent when thumb is fully extended Boundaries Floor Contents Lateral Anterior wall Abductor Pollicis longus Radially Extensor Pollicis Brevis Medially Medial Posterior wall Extensor Pollicis Radial styloid Scaphoid smooth convex articular surface Trapezium Base of First Metacarpal Cephalic vein Radial artery Supercial radial nerve
