颈椎间盘突出(Herniated Disc - Cervical)

颈椎间盘疝出,或颈椎神经根病,是一小部分椎间盘突出导致颈部脊神经受压。小的疝出有时称为膨出或突出,当人们因疝出而遭受疼痛,常描述为神经挤压痛。

Introduction(概述)

  A cervical disc herniation, or cervical radiculopathy, occurs when a small portion of a disc ruptures and causes pressure on spinal nerves in the neck. Small herniations are sometimes called bulges or protrusions, and people experiencing pain from the herniation often describe it as a pinched nerve.

Symptoms(症状)

  Depending on which cervical disc has herniated, the specific pain symptoms may vary. In general, pressure on a spinal nerve causes discomfort in various sites along one or both arms, frequently down to the hand. There can be shooting, burning pains, weakness, and/or numbness. In some instances, a cervical herniation can cause pressure on the spinal cord, a condition called cervical stenosis. Stenosis can lead to a medical condition called myelopathy. Myelopathy symptoms can include neck stiffness, numbness or heaviness in the arms and hands, or a shock-like feeling down the arms or legs. In severe cases, there can be difficulty using the arms and hands or difficulty walking.

  根据颈椎间盘疝出的节段不同,疼痛症状的细节有所不同。通常,当脊神经受压,会引起一侧或双侧上肢不同部位的不适,经常放射到手部,包括枪击样、烧灼样疼痛,无力和/或麻木。有时,颈椎间盘疝出会压迫脊髓,导致颈椎管狭窄。椎管狭窄会引起脊髓病变。脊髓病变的症状包括颈部僵硬、胳膊和手的麻木或沉重感,或闪电样感觉下传到双胳膊或双腿。在严重情况下,会出现胳膊和手活动困难,或行走困难。

Causes(病因)

  Cervical disc herniations are most frequently caused by degeneration due to the normal aging process. As small tears in the disc’s outer layer (annulus) develop and enlarge over time, the jellylike inner layer (nucleus) may bulge outward, causing pressure on the spinal cord and nerves. Occasionally, trauma or an episode of heavy lifting causes sudden rupture of the disc resulting in symptoms.

  颈椎间盘疝出常常由于年龄正常变老引起的退变而导致。当椎间盘外层(纤维环)的小撕裂随着时间而发展增大,胶冻状的内层(髓核)会向外膨出,导致脊髓或神经受压。偶尔,创伤或一段负重的经历或导致椎间盘突然破裂,引起症状。

Summary(总结) 

  Arm pain and discomfort from a disc herniation can often be resolved with medication and non-operative treatments (physical therapy). When these treatments are successful, arm pain tends to disappear first and it may take longer for weakness or numbness to improve. Surgery is performed for those whose symptoms do not improve.

  因椎间盘疝出引起的胳膊疼痛或不适往往可以用药物或非手术治疗(理疗)来缓解。当这些治疗有效,疼痛首先趋于消失,但无力和麻木需要更长时间来恢复。如果症状不缓解,就需要进行手术治疗。
