Cauda equina syndrome (CES) is a condition that occurs when the bundle of nerves below the end of the spinal cord known as the cauda equina is damaged. [2] Signs and symptoms include low back pain , pain that radiates down the leg , numbness around the anus, and loss of bowel or bladder control. [ 1 ]
Cauda equina syndrome, a rare disorder affecting the bundle of nerve roots (cauda equina) at the lower (lumbar) end of the spinal cord, is a surgical emergency. [3] Cauda equina syndrome occurs when the nerve roots in the lumbar spine are compressed, disrupting sensation and movement. [ 4 ]
Compression of the cauda equina can cause permanent nerve damage or paralysis which can result in loss of bowel and bladder control and sexual dysfunction. This disorder is called cauda equina syndrome. Other complications include chronic pain. [citation needed]
The two main proposed mechanisms agree that neurovascular compression plays a role. The ischemic theory proposes that poor blood supply to the spinal nerve roots results in NC. In contrast, the venous stasis theory proposes that a combination of low oxygen levels and metabolite buildup are responsible due to venous backup at the cauda equina. [7]
Decompression of the spinal cord or cauda equina [ edit ] Laminectomy is an open or minimally invasive surgical procedure in which a portion of the posterior arch of the vertebrae and/or spinal ligaments is removed from the spine to alleviate the pressure on the spinal canal contents.
Spinal cord compression is a form of myelopathy in which the spinal cord is compressed. Causes can be bone fragments from a vertebral fracture, a tumor , abscess , ruptured intervertebral disc or other lesion.
Severe spinal-cord compression is considered a surgical emergency and requires decompression to preserve motor and sensory function. Cauda equina syndrome involves severe compression of the cauda equina and presents initially with pain followed by motor and sensory.
Cauda equina compression can also be due to stenosis of L4-5 region as well. [1] Even though the CT scan allows for intensive image studying, the fixed nature of the image collection process alone is not enough to reach a definitive diagnosis of lumbar spinal stenosis.
