How to locate
The patient's forearm should be in a relaxed supinated position. The wrist joint space is a more reliable reference point than wrist crease to identify Bizhong EX-UE.
Draw an imaginary line between the midpoint of the wrist joint space and cubital crease. Identify Bizhong EX-UE in the middle of these two point, between the ulna and radius.
