Spinal stenosis

Spinal stenosis is a typical degenerative disease. Aging causes loss of moisture in disc, which in turn causes decreased elasticity or internal deformity of the disc. Once the internal disc ( pulp) is weakened, it will eventually collapse since it can no longer withstand the body weight. The narrowing of intervertebral space caused by this collapse is called spinal stenosis. Many cases of chronic herniation of intervertebral disc lead to the development of spinal stenosis. Moreover, repeated surgeries to remove herniated pulp decrease the amount of internal pulp and frequently cause spinal stenosis.
