Cauda equina syndrome is a condition caused by damage to the cauda equina. The cause is not fully understood and may include inflammation, compression, trauma, congenital dysplasia, and surgical and anesthetic agents. 1. Inflammation: Infection of the spinal canal outside the lumbar dural sac, such as osteomyelitis, can lead to cauda equina syndrome. 2. Compression: Tumors near the spine compress the spinal canal, causing compression damage to the cauda equina nerve root. 3. Trauma: such as lumbar spine injury, fall, etc. may directly damage the cauda equina. 4. Congenital dysplasia: such as developmental lumbar spinal stenosis, part of the nerves in the spinal canal are squeezed and suffer from cauda equina syndrome. 5. Surgery and anesthetics: unavoidable intraoperative manipulation or anesthetics into the subarachnoid space triggers cauda equina syndrome. There are other causes of cauda equina syndrome, you need to go to a regular hospital, under the guidance of a professional doctor to avoid delaying the condition.
