Which artery is palpated when taking the pulse from anatomical snuff box?
Ans radial Explanation • Anastomical box (ASB) has the radial (A) artery as one of its contents. - Radial artery pulsations can be felt in the ASB over the scaphoid and trapezium bones in the floor. • Brachial (B) artery is the content of cubital fossa. It divides into radial and ulnar artery in the fossa itself. • Ulnar (C) artery is a branch of brachial artery which is present in the cubital fossa and passes superficial to the flexor retinaculum to reach the palm. • Ulnar artery gives common interosseous artery which further gives the branches - anterior and posterior interosseous arteries. None of the interosseous (D) arteries enter the anatomical snuff box. • Anatomical snuff box is bounded by the 2 long tendons - Abductor pollicis longus (APL) at the antero-lateral wall and extensor pollicis longus (EPL) at the postero-medial wall. - Extensor pollicis brevis accompanies the abductor pollicis longus, so that the two extensor tendons are at the opposite walls. - de Quervain's tenosynovitis affects the antero-lateral wall of the anatomical snuff box and the tendons involved are APL and EPB. • Floor of the fossa has four bones in the proximal to distal sequence: Radial styloid process → Scaphoid → Trapezium → Base of first metacarpal. - Fracture of scaphoid produces tenderness in the anatomical snuff box. • Roof of the ASB is formed by the skin fascia and 2 import structures are observed here: Cutaneous branch of radial nerve and cephalic vein. • Anatomical snuff box becomes prominent on lateral aspect of the wrist, when the thumb is fully extended.
