Location

On the posterolateral aspect of the forearm, on the line connecting LI5 and LI11, 5 cun proximal to the dorsal wrist crease.

How to locate: With the elbow flexed and the forearm in mid-position, span the line from LI5 to LI11 with both hands to find its midpoint, then go 1 cun toward the wrist. The point is on the dorsolateral side of the radius, 5 cun above the wrist crease.

Distances are in cun, a proportional unit — how to measure.

3D view

Approximate placement, carried over from our 2D body map onto a single adult male model (BodyParts3D) and checked against the point's location text. Shown on one side of the body. Locate the point on your patient by the location text and palpation, not by this model.

Cun on this part of the body
From the cubital crease to the wrist crease: 12 B-cun (WHO 2008, General Guidelines, Proportional Bone (Skeletal) Measurements, p. 12). On the model, the cubital crease = line between the humeral epicondyles. On the model, the wrist crease = line between the radial and ulnar styloid tips.
