Will the cauda equina nerve be damaged after a lumbar puncture?

During the whole process of lumbar puncture, some of the puncture operations are likely to cause subcutaneous hemorrhage at the puncture site, which is related to the patient's physical fitness, health status, and whether coagulation is routine or not. If the subcutaneous hemorrhage caused by the puncture operation is relatively serious, due to the special location, it is easy to directly lead to the injury of the cauda equina nerve or the appearance of cauda equina syndrome after the cauda equina nerve is squeezed by the subcutaneous hemorrhage.

After the cauda equina nerve is squeezed, there will be tingling or numbness in the lower limbs. Abnormalities in these two senses are relatively common symptoms. If there is a very obvious damage to the cauda equina, it may endanger one's mobility, and in more serious cases, it may result in semi-paralysis or paralysis. The proportion of paralysis caused naturally from the cauda equina is relatively small compared to the total number of cases.

The cauda equina belongs to the peripheral nerve, which not only endangers everyone’s motor function and sensory function, but also endangers the patient’s defecation and sensory problems in the saddle area. Therefore, the cauda equina is also a very important innervation area for our body.

The cauda equina syndrome formed after damage to the cauda equina nerve is also regarded as a more serious complication in the lumbar spine complications.
