How to locate disposable bone marrow puncture needle

Frequently selected puncture sites in clinic:

Anterior superior iliac spine: 1 ~ 2cm above the posterior of the anterior superior iliac spine is usually chosen as the puncture point, where the bone surface is relatively flat, easy to fix, and convenient and safe operation.

Posterior superior iliac spine: located on both sides of the sacral vertebra, above the hip bone protrusion.

Fix the bone marrow puncture needle fixator on an appropriate length (about 1.5cm for iliac bone puncture, appropriate length for the fat), fix the skin of the puncture site with the left thumb and index finger, and Pierce vertically on the bone surface with the right hand. When the puncture needle touches the bone, rotate left and right and slowly drill into the piercing substance. When the resistance disappears and there is a sense of empty air and the puncture needle is fixed in the bone, It means it has entered the marrow cavity.
