Which LU point is at the wrist joint, in the depression between the radial artery and the tendon of abductor pollicis longus, level with Shénmén HE-7 (the proximal border of the pisiform bone)?

Which LU point is at the wrist joint, in the depression between the radial artery and the tendon of abductor pollicis longus, level with Shénmén HE-7 (the proximal border of the pisiform bone)?

• A. LU-9
• B. LU-10
• C. LU-7
• D. LU-8

Answer: (A)

Taiyuan, the Lung point at the wrist, sits in the wrist joint depression in a specific groove: between the radial artery and the tendon of abductor pollicis longus, at the level of the transverse wrist crease and the proximal border of the pisiform bone (near Shénmén). That exact relationship—wrist crease level, between the radial artery and the APL tendon, aligned with the pisiform border—matches the description given, so this is the correct site. Other Lung points around the wrist are in different neighboring positions (proceeding higher up the forearm or located on the palm/thenar area), so they don’t fit the described landmarks as precisely.
