How many lumbar vertebrae should I wait for the lumbar puncture needle? How to position it?

In clinical practice, lumbar puncture is generally performed in the intervertebral space of the third, fourth, or fourth and fifth lumbar vertebrae.

Because there are often no important nerves and blood vessels in this area, the spinal cord has basically become the cauda equina below the third and second lumbar vertebrae. Generally speaking, there is no spinal cord for puncture in this part, and the nerves are mainly some nerve fibers of the cauda equina, so the probability of injury after puncture will be smaller, even if the puncture is accidentally punctured on the nerve root, it will not cause some serious damage .

Lumbar puncture surgery is generally better and safer from the median approach, but some patients cannot penetrate from the median, and can also enter from the side, which can also solve the problem.
