What are disc protrusions?

What are disc protrusions?

Disc protrusion is a common form of spinal disc deterioration that can cause neck and back pain. Changes occurring with the regular aging process are responsible for disc deteriorations, although an injury might speed up the degenerative process.

What is normal disc height?

Average lumbar disc height was 5.6 ± 1.1 mm for men and 4.8 ± 0.8 mm for women at T12/L1, 6.9 ± 1.3 mm for men and 5.8 ± 0.9 mm for women at L1/2, 8.1 ± 1.4 mm for men and 6.9 ± 1.1 mm for women at L2/3, 8.7 ± 1.5 mm for men and 7.6 ± 1.2 mm for women at L3/4, 9.2 ± 1.6 mm for men and 8.5 ± 1.6 mm for women at L4/5.

What is Pseudodisc?

pseudodisc of anterolisthesis: deformity of annular fibers due to anterolisthesis mimicking a true protrusion or bulge.

What is disc dissection?

Disc desiccation is one of the most common features of degenerative disc disease. It refers to the dehydration of your discs. Your vertebral discs are full of fluid, which keeps them both flexible and sturdy. As you age, the discs begin to dehydrate or slowly lose their fluid.

What causes disc height loss?

Staying in one position too long or having poor physical mechanics when moving can put added stress on certain spinal discs and contribute to degeneration and height loss. Smoking – Smoking is bad for your health for a number of reasons, but it also can really impact your spinal discs.

What is the normal distance between L5 and S1?

Computed tomographic scans and anatomic evaluations showed that there was an average 22-mm distance between the L5 and S1 nerve roots available to enter the L5-S1 disc space.

Is disc protrusion same as herniation?

Herniation and protrusion are two words for the same thing. If a piece of the disc breaks off, it’s called a sequestered fragment. Surgery is almost always needed for sequestration. The loose piece can enter the spinal canal and put pressure on the spinal cord or spinal nerve roots causing serious problems.

What happens when a disc completely degenerates?

Over time, a degenerating disc may break down completely and leave no space between vertebrae, which can result in impaired movement, pain, and nerve damage.

How do you treat disc height loss?

Treatment may include occupational therapy, physical therapy, or both, special exercises, medications, losing weight, and surgery. Medical options include injecting the joints next to the damaged disc with steroids and a local anesthetic. These are called facet joint injections.

Can you increase disc height?

Thus, another treatment option is motorized decompression, a technique designed to lessen pressure on the discs, vertically expand the intervertebral space, and restore disc height[5–7].

How is the abnormally displaced nucleus pulposus described in disc herniation?

In the case of disc herniation then the abnormally displaced nucleus pulposus should be described in terms of its position in both axial and sagittal planes. Disc herniations are localized in the axial plane into several zones: The pedicle and disc are used as reference points for craniocaudal localization on sagittal images: 1.

What is degenerative disc disease (DDD)?

Degenerative disc disease (DDD) is an exceedingly common entity in the spine, encountered with increasing frequency throughout life and becoming almost universal in late adulthood to a varying degree.

What is disc herniation?

Disc herniation. Dr Daniel J Bell ◉ and A.Prof Frank Gaillard ◉ ◈ et al. Disc herniation refers to the displacement of intervertebral disc material beyond the normal confines of the disc but involving less than 25% of the circumference (to distinguish it from a disc bulge).

What is disc desiccation?

Disk desiccation. Disk desiccation is an extremely common degenerative change of intervertebral discs. The incidence climbs with age, and to a large degree a gradual dehydration is a ‘normal’ part of disk aging. It results from replacement of the hydrophilic glycosaminoglycans within the nucleus pulposus with fibrocartilage.
