Why is a spinal tap done between L3 and L4?
The insertion of a needle under local anaesthetic requires careful positioning to prevent injury to the spinal cord.

Palpate that interspace (L3-L4), the interspace above (L2-L3), and the interspace below (L4-L5) to find the widest space.
Why is a spinal tap performed below L2 of the spinal cord?

Why is it relatively safe to do a spinal tap at L3-L4?
Which landmark can you use to find this level? The spinal cord usually ends at the inferior border of L1 or the superior border of L2. Therefore, inserting the needle between L3 and L4 or L4 and L5 is relatively safe. This level corresponds to the lumbar cistern.

This will in turn create the greatest interspinous distance (opens the gap) through which to access the intrathecal space.
