Location

On the lower back, on the posterior midline, below the spinous process of L5.

How to locate: With the patient prone, find L4 on the line joining the iliac crests, palpate down to the next spinous process (L5), and locate the point on the midline just below it, at the lumbosacral junction.

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