Spinal Stenosis
The vertebrae are the bones that make up the lumbar spine (low back). The spinal canal runs through the vertebrae and contains the nerves supplying sensation and strength to the legs. Between the vertebrae are the intervertebral discs and the spinal facet joints The discs become less spongy and less fluid filled with age. This can result in reduced disc height and bulging of the hardened disc into the spinal canal. The bones and ligaments of the spinal facet joints can thicken and enlarge, due to arthritis, also pushing into the spinal canal. These changes cause narrowing of the lumbar spinal canal which is known as spinal stenosis. This can lead to leg pain with walking activities, general low back pain, weakness, loss of flexibility, and an interference in your normal daily activities.
