Location
On the posterolateral aspect of the wrist, at the radial end of the dorsal wrist crease, distal to the radial styloid process, in the depression of the anatomical snuffbox between the tendons of extensor pollicis longus and brevis.
How to locate: Extend and abduct the thumb fully; the hollow between the two prominent tendons at its base is the anatomical snuffbox. The point is in it at the level of the wrist joint, which you can feel by gently moving the wrist.
Regional anatomy: The needle passes through the extensor retinaculum between the tendons of extensor pollicis longus and brevis, reaching the tendon of extensor carpi radialis longus; the radial artery runs through the floor of the snuffbox.
Distances are in cun, a proportional unit — how to measure.
