Cervical Artificial Disc Replacement
A Patient's Guide to Cervical Artificial Disc Replacement
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.
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.
This guide will help you understand:
What parts of the spine are involved?
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.
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.
On the left and right side of each vertebra is a small tunnel called a neural foramen. (Foramina is the plural term.) The two nerves that leave the spine at each vertebra go through the foramina, one on the left and one on the right. The intervertebral disc sits directly in front of the opening. A bulged or herniated disc can narrow the opening and put pressure on the nerve. A facet joint sits behind the foramen. Bone spurs that form on the facet joint can project into the tunnel, narrowing the hole and pinching the nerve.
A special type of structure in the spine called an intervertebral disc has two parts. The center, called the nucleus, is spongy. It provides most of the shock absorption in the spine. The nucleus is held in place by the annulus, a serie...
