Degenerative disc disease; Other names: Degenerative disc disorder, intervertebral disc degeneration: Degenerated disc between C5 and C6 (vertebra at the top of the picture is C2), with osteophytes anteriorly (to the left) on the lower portion of the C5 and upper portion of the C6 vertebral body.
The second disc replacement to achieve wide clinical use was the prodisc total disc replacement; it continues to have worldwide use today. Designed by French orthopedic spine surgeon Thiery Marnay, M.D., in the late 1980s, early implantations of the prodisc device began in 1990, with a 7-11 year follow-up published in 2005.
Any of the factors below may cause the spaces in the spine to narrow. Spinal ligaments can thicken (ligamenta flava) [24] [25] Bone spurs develop on the bone and into the spinal canal or foraminal openings; Intervertebral discs may bulge or herniate into the canal or foraminal openings [26] Degenerative disc disease causes narrowing of the ...
Some of the common cervical spine diseases include degenerative disc disease, cervical stenosis, and cervical disc herniation. Degenerative disc disease occurs over time when the discs within each vertebra in the neck begin to fall apart and begin to disintegrate. Because each vertebra can cause pain in different areas of the body, the pain ...
The natural evolution of disc disease and degeneration leads to stiffening of the intervertebral joint. This leads to osteophyte formation—a bony overgrowth about the joint. This process is called spondylosis, and is part of the normal aging of the spine. This has been seen in studies of normal and diseased spines.
Degenerative changes cause compression of the spinal cord. Degenerative disc disease (DDD) may trigger the pathogenesis of neurogenic claudication. [17] When intervertebral discs degenerate and change shape in DDD, the normal movements of the spine are interrupted.
