Why Does A Lumbar Puncture Cause Cauda Equina Nerve Damage?

The cauda equina nerve is composed of 10 pairs of nerve roots originating from L2-5, S1-5 and caudal ganglia. It doesn't mean that the cauda equina starts at L2. The cauda equina connects to the spinal cord at the conus medullaris level in L1, so the cauda equina is equally likely to suffer if the upper nerve is damaged and something goes wrong. In the process of lumbar puncture, hematoma at the puncture site may be caused by partial puncture, which is relatively related to the patient's physical content, physical condition, and whether the coagulation function is normal. If the puncture results in severe hematoma, it is very easy to directly cause cauda equina nerve injury or cauda equina syndrome after the compression of the cauda equina nerve by hematoma due to the particularity of the location.
