Friends with a history of spinal stenosis must know what cauda equina syndrome is.
In the face of lumbar spinal stenosis, everyone must have such questions. Why do you have to understand cauda equina syndrome if you have a history of lumbar spinal stenosis? What's the connection between them? Bian Xiao will take you to understand the relationship between lumbar spinal stenosis and cauda equina syndrome.

The concept of lumbar spinal stenosis: refers to various forms of spinal canal, neural tube and intervertebral foramen stenosis, as well as a series of low back pain and a series of nervous system symptoms caused by the change of spinal canal volume caused by soft tissue and the stenosis of dural sac itself; It's called lumbar spinal stenosis

The concept of cauda equina syndrome: cauda equina syndrome is also called cauda equina nerve damage; Mostly due to various congenital and acquired reasons, the lumbar spinal canal is absolutely or relatively narrow, and the cauda equina nerve is compressed, resulting in a series of neurological dysfunction.

What is the relationship between lumbar spinal stenosis and cauda equina syndrome? The reason for this is the following:

Reason 1: The spinal canal is connected with the sacral canal of the sacrum by the hole of the free vertebra, with the foramen magnum of the occipital bone, with the cranial cavity, and ends at the sacral canal hiatus. Its contents include spinal cord, spinal cord sac, spinal nerve roots, blood vessels and a small amount of connective tissue, so once spinal canal stenosis oppresses cauda equina, it will cause a series of symptoms, which is a major factor leading to cauda equina syndrome.

Reason 2: The cauda equina nerve branches are located in Lumbar 2- Lumbar 5, and the sacral nerve 1- Sacral 5 and caudal nerve. There are ten pairs of nerve roots, which pass through the intervertebral foramen of the corresponding vertebrae respectively, forming a cauda equina-like structure called cauda equina nerve. It mainly innervates lumbosacral caudal nerve, mainly manifested as abnormal sensation around the saddle area, which can cause numbness or stimulation, accompanied by incontinence or abnormal sensation of lower limbs; Therefore, partial lumbar spinal stenosis will compress the cauda equina, causing the above symptoms and cauda equina syndrome.

The above is the relationship between lumbar spinal stenosis and cauda equina syndrome, so friends with spinal stenosis or related history need to know what cauda equina syndrome is. Once the symptoms are found, it is recommended to check, treat and recover in time!
