Cervical implants are orthopedic devices implemented by orthopedic surgeons to decompress and stabilize the spine. These devices are implanted either from the front (anterior) of the spine or from the back (posterior). We cover the previous implants below: The objectives of cervical spine surgery include:
- Reduce the pressure on the nerve (s) by decompression (for example, the surgical removal of tissues that push a nerve).
- Stabilizes the cervical spine by fusing or more cervical vertebrae.
Anterior cervical approach implantsJackets or interbody spacersSpacers and cages are placed between two vertebrae. Its purpose is:
1. Keep the space between the vertebrae (if the space becomes too narrow, the nerve roots can get trapped).
- Keep the spinal alignment (for example, a healthy neck has a specific curve, a spacer can help restore this curve) and / or
- Promote spinal fusion (for example, join (fuse) two or more vertebrae together).
The cages (an orthopedic implant ) are available in different sizes and shapes; Some are cylinder-shaped and others are box-shaped. The cages are placed or fit in the vertebral column between the vertebrae. Often, the cages are made of bone fiber, plastic, metal or carbon. Bone chips (allograft, autograft, other bone graft substitutes or other bone growth stimulating substances (eg, demineralized bone matrix) can be included in the cage.For months after surgery, the hope is that the cage will allow increase the fusion between the vertebrae below and above.The fusion increases the stability of the spine.
Spacers are solid devices and bone can not be packed inside. A spacer is used to help restore or correct the alignment of the spine. The anterior cervical plates are attached to the front of two or more vertebrae. The plates help:
- Increase the stability of the cervical spine immediately after surgery.
- Stabilize the cervical spine while it heals.
- Increase the chances of a successful solid fusion.
- It helps reduce the time the patient may require using a cervical collar after surgery.
The plates are made with screw holes through which bone screws are placed in the adjacent vertebral bodies (to be fused) to anchor the plates in the proper place. Both the screws and the plates come in different sizes and designs. Most plates are made of metal (mostly titanium); Some are made of plastic. Certain newer plates are made of composite materials that dissolve after fusion occurs. Some plate designs are self-compressible to help promote spinal fusion.
Artificial cervical discs: the spine surgeons of the world are interested in artificial cervical discs to treat degenerative diseases. It is believed that maintaining movement between the vertebrae is better than spinal fusion. Early studies report that artificial cervical discs can help slow down the procedure or prevent adjacent disc degeneration. The procedure is called disc arthroplasty. The artificial discs are made of various materials. Some designs are all made of metal and other plastic and metal compounds. There are several ongoing FDA trials of artificial discs in progress in the United States; some were completed while others continued.
It is encouraging that cervical decompression and stabilization procedures are some of the most successful operations that spine surgeons perform today. Patients generally have a rapid recovery and return quickly to activities of daily living with a marked improvement in their symptoms.
