A Patient’s Guide to Cervical Artificial Disc Replacement

人工颈椎间盘置换术指南

Introduction

简介

Artificial disc replacement(ADR) is relatively new. In June 2004, the first ADR for the lumbar spine (low back) was approved

by the FDA for use in the US. Replacing a damaged disc in the cervical spine (neck) is a bit trickier. The disc is part of a complex joint in the spine. Making a replacement disc that works and that will last is not an easy task. There are now several Cervical artificial disc replacement devices that have been approved by the FDA for use in the United States.

相比较而言，人工颈椎间盘置换术是一项新技术。在2004年6月，美国FDA批准开展了第一例人工腰椎间盘置换术。而置换受损的颈椎间盘有点棘手。椎间盘是脊柱中复杂关节的一部分。想要让置换的椎间盘能运作并能持久发挥作用，这并非易事。现如今有几种人工颈椎间盘置换装置已经在美国获得FDA的批准。

The artificial disc is inserted in the space between two vertebrae. The goal is to replace the diseased or damaged disc while keeping your normal neck motion. The hope is that your spine will be protected from similar problems above and below the affected spinal level.

人工间盘植入于两椎体间。其目的是置换病变或损伤的椎间盘并保持颈部正常的运动。希望保护你的脊柱免受相邻病变椎节的影响而产生类似问题。

What parts of the spine are involved?

涉及到哪个部位的脊柱？

Disc replacement typically occurs at cervical spine levels C4-5, C5-6, or C6-7. The first seven vertebrae make up the cervical spine. Doctors often refer to the cervical vertebrae as C1 to C7. The cervical spine starts where the top vertebra (C1) connects to the bottom of the skull. The cervical spine curves slightly inward and ends where C7 joins the top of the thoracic spine (the chest area) at the first thoracic vertebra, T1.

通常椎间盘置换在颈4-5、5-6或6-7颈椎水平进行。头端七个椎

体构成了颈椎。医生们经常所指的颈椎是指颈1到颈7。颈椎起始于颈1与颅底的连接处。颈椎曲度轻度前凸，终止于颈7在胸1连接胸椎处。

Each vertebra is made of the same parts. The main section of each cervical vertebrae, from C2 to C7,is formed by a round block of bone, called the vertebral body. A bony ring attaches to the back of the vertebral body. This ring has two parts. Two pedicles connect directly to the back of the vertebral body. Two lamina bones join the pedicles to complete the ring. The lamina bones form the outer rim of the bony ring. When the vertebrae are stacked on top of each other, the bony rings form a hollow tube that surrounds the spinal cord. The laminae provide a protective wall around the spinal cord.

每个椎体由类似的部分构成。从颈2到颈7，每个颈椎的主要部分是由被称之为椎体的圆形骨块构成。一个骨性环连接椎体背侧。骨环有两部分构成。两个横突直接连接椎体背侧。两侧椎板连接横突封闭骨环。椎板构成了骨环的外侧边缘。当脊椎相互堆叠，骨环则组成了一个围绕脊髓的中空管道。横突提供了围绕脊髓的保护结构。
