Do lumbar puncture needle operation can cause syringomyelia?

These are two different concepts. Lumbar puncture surgery is only to extract a certain amount of cerebrospinal fluid for related examination after the puncture needle enters the subarachnoid space through the spinal ligaments and intervertebral discs. In adults, this operation avoids the spinal cord and will not cause any damage to the spinal cord. Syringomyelia is a chronic, progressive lesion of the spinal cord. The etiology is unclear, but the lesions are characterized by tubular cavities in the spinal cord (mainly gray matter) and glial (non-nerve cell) hyperplasia. It usually occurs in the spinal cord of the neck. When the disease involves the medulla oblongata, it is called a cavity of the medulla oblongata. Where you misunderstand is that the puncture needle may cause mechanical damage to the spinal cord during lumbar puncture surgery instead of another spinal cord disease with unclear etiology. So the conclusion is that lumbar puncture surgery does not cause syringomyelia.
