Top 10 Spinal Injuries
Disks are shock absorbers that normally contain water in their central portion. As aging progresses disks tend to lose that water. As a result, disks may lose their normal height.
Literally slipped vertebra in Greek, degenerative spondylolisthesis is the end result of degenerative disk and facet joint disease except that instead of the disk merely losing its height the whole vertebra slips forward on the one below.
When a disk with a weakened wall tears it may allow the central portion of the disk to push through the tear or herniate.
Bacterial infection of a vertebra or disk does not commonly occur, but persons with an immune deficiency and those who use illicit drugs intravenously areat risk.
A number of conditions can cause pain that is perceived in and around the spine, including kidney stones, uterine diseases, pregnancy, fibromyalgia, aneurysm of the aorta or a tumor involving the pancreas.
Loss of bone mineral causes weakening of the vertebrae, a condition commonly associated with menopause in women, but also occurring in men after the age of 70 years.
The most common form of spinal deformity is scoliosis, which may occur during the adolescent growth spurt or develop in adulthood secondary to degenerative disk disease over several spinal levels.
Or narrowing of the spinal canal, is typically the end result of progressive degenerative disk and facet joint disease resulting in compression of the nerve roots in the spinal canal.
The soft tissues of the spine (muscles and ligaments) may be injured due to overloading or awkward positioning. Individuals who are physically de- conditioned are susceptible to straining injuries of the lower back.
By far, the most common cause of a tumor involving the spine is due to metastasis from a cancer at another site.
