前路颈椎间盘切除融合术(Anterior Cervical Discectomy and Fusion)

  颈椎间盘突出压迫脊髓或神经,有些病例需要进行前路颈椎间盘切除并植骨融合内固定(Anterior Cervical Discectomy and Fusion,缩略为ACDF)。介绍前路颈椎间盘切除的适应症及方法。

 


  Anterior Cervical Discectomy and Fusion

  前路颈椎间盘切除融合术

  If you have a condition in your neck that puts pressure on your spinal cord or spinal nerves. Your doctor may recommend an anterior cervical discectomy and fusion.
  
  如果您脖子的病变压迫了脊髓或神经,医生可能会推荐进行前路颈椎间盘切除融合术。

  The spine in your neck also called the cervical spine has seven seperate bones called vertebrae. The front of each vertebra is called the vertebral body, except for the first vertebra. Between most vertebrae is a soft cushion  called an intervertebral disc. The back part of each vertebra has a curve section called the vertebral arch. Except for the first vertebra, each vertebral arch has a bony projection called the spinous process. On each side of the spinous process is a flat piece of bone called a lamina. The vertebral arch of the vertebra surrounds and protects your spinal cord, a column of nerves tissue connecting your brain to other nerves in your body.
  
  脖子这一片脊柱称作颈椎,由7块称为脊椎骨的单独的骨头组成。除了第一颈椎,每个脊椎骨的前部称为椎体。在大部分脊椎骨之间都有软骨垫片,称为椎间盘。每个脊椎骨的后部有弯曲的部分称为椎弓。除了第一颈椎,每个椎弓都有骨性突起,称为棘突。在棘突的两侧,是一片扁平的骨头,称为椎板。脊椎骨的椎弓包绕并保护脊髓。脊髓是连接大脑和身体其它神经的柱状的神经。

  Your spinal cord passes through an inclosed space called the vertebral canal, which is formed by the vertebral arches of your vertebrae. Over time, your cervical spine may develop problems, such as a bulging disc , a herniated or ruptured disc, or bony growth on your vertebrae called bone spurs. These changes can narrow your vertebral canal and put pressure on your spinal cord or the nerves that branch off it. The pressure can cause neck pain and stiffness, or pain, numbness and weakness in your arms or hands.
  
  脊髓在由脊椎骨的椎弓形成的封闭空间(称为椎管)穿行。岁月流逝,颈椎可能出现诸如椎间盘膨出、突出、脊椎骨长出骨赘(骨刺)等病变。这些变化会使椎管变窄,并压迫脊髓或其发出的神经,导致颈部疼痛和僵硬,或胳膊和手的疼痛、麻木和无力。

  Your surgeon will make an incision on your neck. The front of your cervical spine containing the damaged disc will be exposed. Your surgeon will remove the entire damaged disc. This helps relieve the pressure on your spinal cord and nerve roots. Then your surgeon will remove any bone spurs. The vertebral bodies above and below the removed disc will be trimmed to allow placement of a bone graft.
  
  术者将在颈部作一切口。显露包含受损椎间盘的颈椎的前部。去除整个受损的椎间盘,这样有利去解除脊髓或神经根上的压迫,并去除骨赘。对摘除的椎间盘上下的椎体进行修整,以便进行植骨。

  Your surgeon may use a plastic spacer filled with synthetic bone graft, or bone graft may be taken from another donor before your procedure. The bone graft may be placed between two prepared vertebrae, allowing them to fuse together.
  
  术者可能会使用一种填满合成骨的塑料间隔器,或术前从捐献者身上获取的植骨块。移植骨块放于两个准备好的椎体之间,以利于它们融合到一起。

  Your surgeon may attach a metal plate with screws to keep your spine stable, while your bone graft assists in fusing the vertebrae together.
  
  术者可能加用钢板螺钉以保持脊柱的稳定,促进移植骨块与椎体融合到一起。

  Your skin incision will be closed with skin glue or skin closure tape.
  
  术者会用皮肤胶水或皮肤闭合胶关闭切口。

  Your neck may be placed in a collar to keep it still while your vertebrae fuse.
  
  在椎体融合过程中,可能使用颈托固定颈椎,以保持颈椎静止不动。
