A trephine biopsy should never be performed on the sternum, due to the risk of injury to blood vessels, lungs or the heart. Bone marrow aspiration may also be performed on the tibial (shinbone) site in children up to 2 years of age while spinous process aspiration is frequently done in a lumbar puncture position and on the L3-L4 vertebrae.
T-ALL can spread to the brain and spinal cord, [2] which can be diagnosed through lumbar puncture assessment. Lumbar puncture helps identify leukemic cells in the cerebrospinal fluid (CSF). [3] Even if leukemic cells are not found in the CSF at the time of diagnosis, it is highly likely that they will spread there over time.
For those children with spinal cord diseases, lumbar puncture may damage the spinal cord due to possibility of tethered spinal cord syndrome where the spinal cord is located below than the usual spinal termination level. [3] Therefore, lumbar puncture should be done at the lowest position as possible for such cases. However, spinal cord injury ...
