腰椎滑脱常见两种原因，老年人往往是退变性滑脱，年轻人常由椎弓峡部裂（或称椎弓崩裂）引起。本视频主要介绍峡部裂性腰椎滑脱的病因、发病原理以及可能引起的症状。

Isthmic spondylolisthesis is a lumbar spinal condition in which a fracture of the isthmus causes one vertebral body to slip forward on top of the vertebral body below it.

峡部裂性腰椎滑脱是由于峡部裂使一个椎体在另一个椎体上面滑动产生的一种病症。

The isthmus, or pars interarticularis, is a small, thin segment of bone that connects the facet joints at the back of the spine.

峡部或称椎弓峡部，是脊柱背侧连接上下关节突之间的一段小而细的骨段。

A fracture of the isthmus, known as a spondylolysis, is usually a result of stress to the spine.

峡部裂，即椎弓崩裂，常是脊柱应力的结果。

A spondylolysis can, but does not always lead to slippage of the vertebrae, known as spondylolisthesis.

椎弓崩裂可以，但不总是会导致椎体滑脱。

Isthmic spondylolisthesis most commonly occurs at the lowest level of the lumbar spine, the L5-S1 segment. Spondylolisthesis is graded on a scale from 1 to 4, measuring how far one vertebra has slipped forward on another.

峡部裂性腰椎滑脱最常见于最下面的腰椎，腰5/骶1节段。腰椎滑脱根据测量一个椎体相对于另一个椎体滑动的距离分为1-4度。

Isthmic spondylolisthesis does not always cause immediate symptoms of pain. When it does, it usually manifests as a deep ache in the lower back.

峡部裂并不总是立即引起疼痛症状，当有症状时，通常表现为腰部深部疼痛。

Pain from isthmic spondylolisthesis tends to be worse when standing or walking, or during activities that involve bending backward. There may be tightness in the hamstrings.

因峡部裂性腰椎滑脱引起的疼痛往往在站立或行走后以及包括向后弯曲等活动时加重。可能还会有肌肉紧张。

Sometimes, the disc space between the two vertebrae can wear out. The resulting compression of nerve roots leads to radiating pain, numbness, or weakness in the legs.

有时，两个椎体间的椎间盘空间会磨损变窄，可压迫神经根引起下肢的放射痛、麻木、乏力。

Isthmic spondylolisthesis is a fairly common condition among young athletes.

在年轻的田径运动员中，峡部裂性腰椎滑脱是相当常见的情况。
