- Foraminal Stenoses
Exostoses of bone tissue or protrusions of disk tissue can lead to constrictions at the nerve exits of the vertebral joints, which are called foraminal stenoses. This results in the irritation of the nerve roots as well as feelings of numbness and instability while walking.
A foraminal stenosis can be caused by facet arthrosis. This phenomenon of wear and tear results in an increased development of wild bone mass, which may constrict the nerve exit from behind. Yet disk tissue invading the nerve exit or exostoses of the vertebral bodies can pressure it also from the front. This can happen, for example, following old disk prolapses or in the wake of degenerative changes in the disks (osteochondrosis).
