Why can bone marrow aspiration also pass through the sternum?

Bone marrow aspiration has important diagnostic value for blood diseases, especially leukemia. Different types of diseases can be diagnosed through bone marrow examination; it is also very helpful for the diagnosis of certain parasitic and bacterial diseases.

In addition, for long-term fever, liver, spleen, and lymph node enlargement, bone marrow biopsy can be performed to confirm the diagnosis. Bone marrow puncture can be performed by iliac crest puncture, sternal puncture, tibial puncture and spinous process puncture. Osteoporosis at the iliac crest, thinner cortex, and more bone marrow fluid, puncture is safer and easier to perform. Bone marrow aspiration is not recommended for hemophilia, severe bleeding tendency, local skin infection, etc. For older children who can cooperate, sternum and spinous process puncture can also be used.

Many people think that bone piercing is a very scary thing, but the method is actually very simple. First select the puncture site, inject a small amount of anesthesia locally, and extract a small drop of bone marrow tissue with a bone puncture needle. A skilled doctor operates the entire process of bone piercing, but only a few minutes.

After the bone marrow is extracted, the child can get up and move after the bleeding is stopped by pressing the puncture point. There may be local soreness during the extraction of bone marrow, which can be tolerated by the child. There is no harm to the health of children, and it will not cause long-term damage. Since bone marrow is a tissue with strong regenerative ability in the human body, and the amount of bone marrow extraction is very small, there is no need to worry about hurting the "vigor", and there is no need to supplement additional nutrients.
