人工颈椎间盘置换术(Cervical Disc Replacement)

人工颈椎间盘置换术,是用人工椎间盘假体,替代受损的颈椎间盘,解除突出椎间盘或骨赘对脊髓和神经的压迫,保留病变颈椎间隙的活动度。

  Cervical disc replacement surgery is designed toreplace a damaged spinal disc in the neck with an artificial disc implant.

  人工颈椎间盘置换术是用人工椎间盘植入替代受损的颈椎间盘。

  Damaged cervical discs are most likely to occur at the C4-C5, C5-C6, or C6-C7 levels.

  颈椎间盘受损通常发生于颈4/5、颈5/6、颈6/7节段。

  The damaged disc may be due to conditions such as a cervical disc herniation, and/or osteophytes, also called bone spurs, encroaching upon the nerve root.

  椎间盘损害通常因颈椎间盘突出和/或骨赘(也称骨刺)侵犯神经根等情况引起。

  During cervical disc replacement surgery, a one-to-two-inch incision is made in the front of the neck.

  在人工颈椎间盘置换术中,需要在颈前区作1~2英寸的切口。

  The thin platysma muscle that lies just underneath the skin is cut and moved aside, and the pre-vertebral fascia, a thin layer of tissue that surrounds the spine, is removed to expose the spinal discs.

  切开紧贴皮下的颈阔肌并牵开,分离颈前筋膜(在脊椎周围的一薄层组织),显露颈椎间盘。

  An Incision is made in the outer coating of the disc, called the annulus fibrosus, and the soft inner core of the disc, called the nucleus pulposus, is removed. Most of the damaged disc is extracted, but a small portion may be left intact.

  在椎间盘外层(纤维环)作一切口,将椎间盘的内核(髓核)去除。取出大部分受损的椎间盘,保留小部分椎间盘。

  The disc space between the vertebrae is then restored to its normal height.

  于是,椎体间的椎间隙保留正常的高度。

  This restoration of disc space height aids in the decompression of surrounding nerve roots and makes room for the new artificial disc.

  保留椎间隙高度有助于解除周围神经根压力,并给新的人工椎间盘植入留下空间。

  Using X-ray guidance, the surgeon inserts the artificial disc into the space previously occupied by the natural disc.

  使用X线的引导,术者在原先被自身椎间盘占据的空间植入人工椎间盘。

  There are many different cervical artificial disc designs and materials commercially available.

  目前市场上有各种不同设计类型和材料的人工颈椎间盘。

  Patients can usually leave the hospital after one to two days, with minimal activity restrictions.

  患者在1到2天后可以出院,对颈椎活动的限制较小。
