Bladder channel · point 54

Outer Bladder line

Traditionally used for

  • Bowel health
  • Urinary & fluids
  • Nerves & recovery
  • Pain & joints

Location

On the buttock, 3 cun lateral to the midline, level with the fourth posterior sacral foramen.

How to locate: With the patient prone, find the sacral hiatus, which is level with the fourth posterior sacral foramen; the point is 3 cun lateral to the median sacral crest at that level.

Regional anatomy: Skin and subcutaneous tissue, then gluteus maximus toward the lower border of piriformis; the sciatic nerve runs deep in this region, so deep needling will often send sensation down the leg.

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