T12 - L1 is contraindicated for lumbar puncture.
Lumbar puncture is commonly used to extract the spinal fluid for evaluation.
L2 - L3, L3 - L4, L5 - S1 levels are safely used for lumbar puncture. Spinal cord ends at the L1 level so any puncture above this level is contraindicated as it may affect the spinal cord.
Among these levels, L3 - L4 is the most commonly used disc space for lumbar puncture.
