Location

On the back, on the posterior midline, in the depression below the spinous process of T9.

How to locate: With the patient prone and the arms at the sides, find T7 level with the inferior angles of the scapulae and count down two spinous processes; the point is in the depression below the spinous process of T9.

Regional anatomy: Beneath the skin and subcutaneous tissue the needle passes through the supraspinous and interspinous ligaments toward the ligamentum flavum; the spinal canal and cord lie beyond it.

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