83) Explanation


• The anatomical snuffbox is formed by the tendons of extensor polloicis longus and brevis, and abductor pollicis longus.
• It has the radial artery running in the floor of the snuffbox, and the radial nerve passing to the dorsum of the hand.
• Boundaries of snuff box:
ƒ Postero-medial border is the tendon of the extensor pollicis longus.
ƒ Antero-lateral border is a pair of parallel and intimate tendons of the extensor pollicis brevis and the abductor pollicis longus.
ƒ The proximal border is formed by the styloid process of the radius.
ƒ The distal border is formed by the approximate apex of the schematic snuffbox isosceles
