颈椎管狭窄(Cervical Spinal Stenosis)

颈椎管狭窄是颈椎管各个方向径线减小,或者说容积减小。颈椎管狭窄可减少脊髓和神经的有效空间和血供,引起功能障碍。因此颈椎管狭窄症,是引起椎管狭窄脊髓压迫的各种疾病的统称,不是单一特定的疾病。

  Cervical spinal stenosis with myleopathy is diagnosed when degenerative changes in the cervical spine cause spinal cord compression.

  当颈椎退变引起脊髓压迫,可诊断为颈椎管狭窄伴脊髓病。

  The spinal cord is a nerve bundle that runs from the base of the brain to the low back. In a normal spine, there is ample space for the spinal cord in the spinal canal.

  脊髓是从颅底走行到腰椎的一束神经。在正常脊柱,脊髓在椎管内有充足的空间。

  In cervical spinal stenosis, however, this space becomes too narrow.

  然而,在颈椎管狭窄时,这个空间变得狭小。

  Over time, degenerative changes in the spine can cause the spinal canal to narrow. Having a congenitally narrow spinal canal makes one susceptible to developing cervical spinal stenosis.

  久而久之,脊柱的退变会引起椎管狭窄。如果天生就有椎管狭窄,就更容易发展成为颈椎管狭窄症。

  Degenerative changes can be caused by one or a combination of conditions, such as osteoarthritis or herniated discs.

  退变可因诸如骨关节炎或椎间盘突出等一个或多个病症引起。

  In cervical osteoarthritis, cartilage between the facet joints degenerates over time, resulting in friction between the bones.

  在颈椎骨关节炎,关节突关节的软骨逐渐退变,导致骨与骨之间产生摩擦。

  This friction can lead to the development of osteophytes, or bone spurs, which can encroach upon the nerve roots as they exit the spinal canal through the foraminal opening, or they can encroach centrally on the spinal cord itself.

  这种摩擦会引起骨质增生或骨刺形成,在神经根通过椎间孔开口处离开椎管时压迫神经根,或在中央椎管压迫脊髓本身。

  One or more herniated cervical discs may also contribute to spinal compression if they herniate into the spinal canal.

  一个或多个颈椎间盘突出如果进入椎管,也会造成脊髓压迫。

  Herniated discs may further impinge on nerve roots that already have some foraminal compression from osteoarthritis.

  已经因骨关节炎产生一些椎间孔狭窄者,椎间盘突出可进一步压迫神经根。

  Spinal cord compression, or myelopathy, can affect how the spinal cord functions.

  脊髓受压产生脊髓病,会影响脊髓的正常功能。

  The symptoms of cervical spinal cord compression can include a combination of numbness, tingling, weakness, or pain in the arms, hands, and legs.

  颈脊髓压迫的症状包括同时出现麻木、刺痛、无力,或引起胳膊、手和腿的疼痛。

  Symptoms can also include a loss of bladder or bowel control, or problems with balance or coordination, such as a shuffling gait or tripping easily when walking.

  症状还包括大小便不能控制、平衡或协调能力障碍,以及行走不稳、拖行步态或走路时容易绊倒。

  Cervical spinal stenosis with myleopathy can be permanently disabling if it is allowed to progress too far. It can be treated with a cervical decompression surgery.

  颈椎管狭窄伴脊髓病如任其发展,可造成永久性的功能障碍,应通过颈椎减压手术进行治疗。
