DDD can cause mild to severe pain, either acute or chronic, near the involved disc, as well as neuropathic pain if an adjacent spinal nerve root is involved. Diagnosis is suspected when typical symptoms and physical findings are present; and confirmed by x-rays of the vertebral column.
Subacute combined degeneration of spinal cord; Diagram of the principal fasciculi of the spinal cord. (In subacute combined degeneration of spinal cord, the "combined" refers to the fact that the dorsal columns and lateral corticospinal tracts are both affected, in contrast to tabes dorsalis which is selective for the dorsal columns.)
In the more narrow sense, it refers to spinal osteoarthritis, the age-related degeneration of the spinal column, which is the most common cause of spondylosis. The degenerative process in osteoarthritis chiefly affects the vertebral bodies, the neural foramina and the facet joints (facet syndrome). If severe, it may cause pressure on the spinal ...
Because each vertebra can cause pain in different areas of the body, the pain from the disease can be sensed in the back, leg, neck area, or even the arms. When the spinal canal begins to lose its gap and gets thinner, it can cause pain in the neck, which can also cause a numb feeling in the arms and hands.
There are many causes for spinal stenosis but degenerative changes are a precursor to spinal stenosis becoming symptomatic. [33] While the exact prevalence of degenerative LSS is unknown, it is estimated that it ranges from 1.7% to 13.1%. [34] However, the results from these statistics have been put into question.
Myelopathy describes any neurologic deficit related to the spinal cord. [1] The most common form of myelopathy in humans, cervical spondylotic myelopathy (CSM), [2] [3] also called degenerative cervical myelopathy, [4] results from narrowing of the spinal canal (spinal stenosis) ultimately causing compression of the spinal cord. [5]
Some authors favour degeneration of the intervertebral disc as the major cause of spinal disc herniation and cite trauma as a minor cause. [7] Disc degeneration occurs both in degenerative disc disease and aging. [8] With degeneration, the disc components – the nucleus pulposus and annulus fibrosus – become exposed to altered loads ...
Spondylosis deformans is a disease of the spine in humans and other vertebrates. It occurs when intervertebral discs begin to degenerate, leading to the formation of bony spurs or bridges around the disc and nearby spinal joints. Severe cases can result in pressure on the spinal nerves, causing neurological signs and symptoms. [1]
