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

受压的另一个原因是椎管狭窄，即椎管或椎孔的狭窄。

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

我这么 椎管狭窄不可能啊 我查过的。

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

最后，任何椎管内的占位，如肿瘤、囊肿或脓肿，都可压脊。

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

所有均通过相应的椎孔离开椎管；椎孔开口于两块相邻椎体之。

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

另外，椎管狭窄也可引起压；椎管狭窄，顾名思义，指的是腰椎脊髓腔的狭窄。

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，比如是由肿瘤或椎管狭窄引起时，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.

最后是椎管内的任何增生：如肿瘤、囊肿或脓肿，也可导致压脊髓。

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

腰椎滑脱最常见的类型是向前滑脱，即椎骨相对向前移动并使椎管变窄，从而压。

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.

它是由脊腰4（L4）、腰5（L5）、骶1（S1）、骶2（S2）和骶3（S3）组成；这些通过椎孔离开椎管；椎孔为椎骨之、椎盘后方的椎管的开口。

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，脊椎的任何创伤：如车祸、枪击等，都可以直接导致损伤和压，或者引起椎管内出血，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.

它可能是先天性的，也就是说患者出生便有这种情况；或是获性的，通常原因是退行性疾病，如强直性脊柱炎，导致骨重塑，引起椎盘骨化，进而造成椎管狭窄。
