Lumbar Spinal Stenosis 腰椎管狭窄 (Reading & Sharing)
Definition, Pathophysiology, Incidence, and Prevalence
Spinal stenosis is a narrowing of the spinal canal, lumbar stenosis is the narrowing of the lower back, the lumbar portion (Spinal stenosis, 2018). This spinal canal narrowing can place additional pressure onto the spinal cord nerves which may cause the affected individual pain. Ferri (2018) explains that in lumbar stenosis, the spinal nerve roots in the lower back become compressed and this can produce symptoms of sciatica involving: tingling, weakness, and/or numbness that radiates from the low back and into the buttocks and legs, especially with activity. Spinal stenosis can occur due to a variety of reasons. Most people with spinal stenosis are over the age of 50; however, some individuals have congenital defects with their spinal canal, causing compression on the spinal cord (Spinal stenosis, 2018). Other causes of lumbar spinal stenosis include: osteoarthritis of the vertebrae can prompt the formation of bone spurs, Paget’s disease, herniated vertebrae, tumors, spinal trauma, and thickened ligaments (Ferri, 2018).

Lumbar Spinal Stenosis / Reading and Sharing
Lumbar spinal stenosis is a narrowing of the spinal canal at the lumbar region (Spinal stenosis, 2018). Ferri (2018) explains that in lumbar stenosis, the spinal nerve roots in the lower back become compressed, and this can place additional pressure onto the spinal cord nerves which can produce symptoms of sciatica involving: tingling, weakness, and/or numbness that radiates from the low back and into the buttocks and legs, especially with activity.
There are not many studies that research the incidence and prevalence of lumbar spinal stenosis. It is estimated that over 200,000 adults have lumbar spinal stenosis and that number is expected to be 64 million in the elderly by the year 2025 (Wu et al., 2017). Most people with spinal stenosis are over the age of 50; however, some individuals have congenital defects with their spinal canal, causing compression on the spinal cord (Spinal stenosis, 2018).
