The spinal cord continues below L2 down into the sacrum as many separate strands of nerve pathways, the cordae equina, bathed in CSF.

What level of lumbar puncture do LP?

Therefore a lumbar puncture is generally performed at or below the L3-L4 interspace. As a general anatomical rule, the line drawn between the posterior iliac crests often corresponds closely to the level of L3-L4. The interspace is selected after palpation of the spinous processes at each lumbar level.

Can a lumbar puncture detect Alzheimer’s?

Alzheimer’s disease is characterised by the abnormal clumps of proteins called amyloid and tau in the brain. These changes are reflected in the levels of proteins in the cerebrospinal fluid, so a lumbar puncture can indicate whether the brain is affected by Alzheimer’s disease.
