Why is the bone marrow of children under 2 years old to take the tibial tuberosity?

Adult bone marrow puncture often takes the anterior superior iliac spine, posterior superior iliac spine, lumbar spinous process, manubrium, etc., but children need to choose the tibial tubercle.

Suggestions: This is mainly because the above-mentioned bone marrow puncture site is too small for children, and it is not easy to puncture successfully, and the tibial tubercle is easy to touch and easy to puncture successfully, so choose the tibial tubercle, which is the tibial tuberosity. .

It is a diagnosis and treatment technique that inserts a puncture needle into the body cavity to extract secretions for testing, injects gas or contrast agent into the body cavity for contrast examination, or injects drugs into the body cavity. The purpose of puncture is blood test, blood transfusion, infusion and catheter placement for angiography.

Using lumbar puncture needle to puncture the subarachnoid space of the lumbar spinal cord is an important clinical auxiliary examination method in neurology. It can be used to measure cerebral pressure, collect cerebral effusion for routine, biochemical and bacteriological examination, tumor cell and enzymatic examination, and provide the basis for the diagnosis of intracranial inflammation, tumor, hemorrhage and cerebral white matter demyelination disease. However, when the intracranial pressure is too high, the lumbar puncture should be careful, it is best not to discharge the fluid, and only use the cerebrospinal fluid in the hose connected to the brain pressure gauge for testing to avoid brain herniation. Contrast can also be injected into the subarachnoid space for descending or ascending angiography. Air (or oxygen) can also be injected into the subarachnoid space, directional flow into the brain, do spinal lesions angiography, ventriculo-encephalography and cisternography.
