When foreign bodies remain in the vertebral canal
for a long period of time, they can slowly degrade or corrode and cause sustained tissue irritation, which can lead to chronic inflammation and progressive damage to nerve roots or spinal cord itself, causing pain or a delayed neurological deficit .
The two most distal screws protruded into the vertebral canal
but spinal cord compression was not suspected (Figure 7).
In the present study, the vertebral canal
diameter was significantly enlarged, and kyphosis was significantly improved.
Nerves in the vertebral canal

There is a significant difference in the size of the lumbar vertebral canal
in different ethnic groups, emphasizing physiology and clinical problems present in that group.
"The most tragic thing was that one of the pellets had landed into the middle of his vertebral canal
in the lumbar area, severing the spinal cord, leading to instant paralysis of his hind legs, so he couldn't have moved from the spot where he was shot at.
This anatomy text focuses on the structures that anesthetists should know: the respiratory pathway, lungs, thoracic wall, and diaphragm; the heart and great veins of the neck; the vertebral canal
and its contents; the peripheral and cranial nerves; the autonomic nervous system; the thoracic inlet; the antecubital fossa; the orbit and its contents; and the abdominal wall; as well as the anatomy of pain.
(1987) compared mensuration of vertebral canal
size of chondrodystrophic dogs and non-chondrodystrophic dogs and inferred that the spinal cord of non-chondrodystrophic dogs occupied a lesser cross sectional area of the vertebral canal
than did the spinal cord of Dachshunds and subarachnoid and epidural spaces were less in Dachshunds than the other group.
Spinal stenosis is a broad term that encompasses all entities that decrease the space available for the spinal cord in the vertebral canal
. According to Postacchini , three forms of degenerative lumbar spinal stenosis can be distinguished.
The greatest diameter of the vertebral canal
was observed at the atlas bone ([C.sub.1]) (0.8 cm).
A 5 x 3 x 3 [mm.sup.3] bone tunnel was drilled in the vertebrae with a bitbrace and the vertebrae must not be drilled through to the vertebral canal
. Bleeding was completely stopped.
