Spinal stenosis is an abnormal narrowing of the spinal canal or neural foramen that results in pressure on the spinal cord or nerve roots. [6] Symptoms may include pain, numbness , or weakness in the arms or legs. [ 1 ]
These exercises were initially developed for men under 50 and women under 40 who had exaggerated lumbar lordosis, whose x-ray films showed decreased disc space between lumbar spine segments (L1-S1), and whose symptoms were chronic, but low grade. [citation needed]
Any forward slipping of one vertebra on another can cause spinal stenosis by narrowing the canal. If this forward slipping narrows the canal sufficiently, and impinges on the contents of the spinal column, it is spinal stenosis by definition. If associated symptoms of narrowing exist, the diagnosis of spinal stenosis is confirmed.
There is an association between intervertebral disc space narrowing and lumbar spine pain. [24] The space between the vertebrae becomes more narrow, resulting in compression and irritation of the nerves. [25] Spondylolithesis is the anterior shift of one vertebra compared to the neighboring vertebra. It is associated with age-related ...
The intervertebral disc is removed and replaced with a small plug of bone or other graft substitute, along with a height restoration device to un-impinge nerves, and in time, the vertebrae will fuse together. Intervertebral disc arthroplasty: also called Artificial Disc Replacement (ADR), or Total Disc Replacement (TDR), is a type of arthroplasty.
Pick-up games are meant to be fun, but jumping into any sport without any conditioning, stretching or warming up can result in serious injury, Dr. Molly McDermott, a sports medicine specialist at ...
This definition reflects the current hypotheses for the pathophysiology of NC, which is thought to be related to the compression of lumbosacral nerve roots by surrounding structures, such as hypertrophied facet joints or ligamentum flavum, bone spurs, scar tissue, and bulging or herniated discs.
Lumbar spinal stenosis is classified as a narrowing of the spinal canal in the lumbar region of the vertebrae. This may lead to compression of the nerve root of the spinal cord and result in pain of the lower back and lower extremities.
