Lumbar spinal stenosis causes many dangerous complications

1. What is the cause of lumbar spinal stenosis?


Causes of spinal stenosis may include:
Degenerative changes can lead to the formation of bone spurs from the vertebral body. These bone spurs can grow into the spinal canal and cause compression of the spinal cord. Degeneration of spinal ligaments (eg, posterior longitudinal ligament, ligamentum fascia) thickens and narrows the lumen of the spinal canal. If ankylosing spondylitis occurs, these joints will enlarge so much that they press on the spinal canal. The anteroposterior diameter of the spinal canal is reduced when a disc herniates or bulges.

2. Symptoms of lumbar spinal stenosis


Sciatica with low back pain, numbness and tightness in the legs. Leg pain when walking: This is a symptom that can occur due to either narrowing of the spinal canal or inflammation of the arteries of the lower extremities. Leg pain from these causes all subside with rest, but with spinal stenosis, the patient often has to sit down for a few minutes to relieve the pain and is often accompanied by low back pain. Although sometimes the symptoms of spinal stenosis come on immediately, they generally develop over a long period of time. The longer a patient with lumbar spinal stenosis stands or walks, the worse the leg pain. Bend forward or sit down will widen the spine and relieve leg pain and other symptoms, but the pain will return if the patient keeps the back straight.

3. Is spinal stenosis dangerous?


In rare cases, lumbar spinal stenosis can cause more serious damage to the point of persistent pain and paralysis of the legs. In most cases, the pain radiates to the legs when walking, and the pain is relieved when sitting (this phenomenon can also be seen in lower extremity arteritis).
Cervical spinal stenosis can be more dangerous due to spinal cord compression and can lead to weakness in the arms and even quadriplegia. This does not happen in the lumbar spine, because the spinal cord is absent in the lumbar spine segment.
