Another cause of nerve compression is spinal stenosis, which is the narrowing of the spinal canal or intervertebral foramen.

神经受压另一个椎管，即椎管或椎间孔。

I'm far too young to get spinal stenosis. I looked it up.

我这么年轻 得椎管不可能啊 我查过。

Finally, any growth within the spinal canal like tumor, cysts, or abscesses can cause compression of the spinal nerves.

最后，任何椎管内占位，如肿瘤、囊肿或脓肿，都可压脊神经。

Each nerve leaves the spinal canal through the corresponding intervertebral foramen, which are openings between two adjacent vertebrae.

所有神经均通过相应椎间孔离开椎管；椎间孔开口于两块相邻椎体之间。

Compression can also be caused by spinal stenosis which is the narrowing of the vertebral foramen in the lumbar vertebrae.

另外，椎管也可引起压；椎管，顾名思义，指腰椎脊髓腔。

It could also develop slowly, like if it's caused by a tumor or spinal stenosis, where the pain increases over time.

疼痛也可能缓慢进展，比如由肿瘤或椎管引起时，那么疼痛久而久之会加剧。

Finally any growths within the spinal canal like tumors, cysts, or abscesses can cause compression on the spinal cord and nerves.

最后椎管内任何增生：如肿瘤、囊肿或脓肿，也可导致压脊髓神经。

The most common type of lumbar spondylolisthesis is anterolisthesis, where a vertebra moves forward and narrows the spinal canal, causing compression of the nerves.

腰椎滑脱最常见类型向前滑脱，即椎骨相对向前移动并使椎管变，从而压神经。

It's formed by the spinal nerves L4, L5 and S1, 2 and 3, which leave the spinal canal through the intervertebral foramen, an opening located between the vertebrae and behind intervertebral discs.

它由脊神经腰4（L4）、腰5（L5）、骶1（S1）、骶2（S2）和骶3（S3）组成；这些神经通过椎间孔离开椎管；椎间孔为椎骨之间、椎间盘后方椎管开口。

Finally, any trauma to the spine, like the one caused by a car crash, gunshot, etc. can lead to nerve damage or compression directly, or by causing bleeding inside the spinal canal, causing compression via hematomas.

最后，脊椎任何创伤：如车祸、枪击等，都可以直接导致神经损伤和压，或者引起椎管内出血，间接通过血肿压。

It can be congenital, meaning that the person is born with it, or acquired, usually due to degenerative disorders like ankylosing spondylitis, where the bones remodel causing intervertebral discs ossification, and the narrowing of the spinal canal.

它可能先天性，也就说患者出生便有这种情况；或获得性，通常退行性疾病，如强直性脊柱炎，导致骨重塑，引起椎间盘骨化，进而造成椎管。
