Cervical Implants Used in Spine Surgery

Cervical implants are orthopedic devices deployed by Orthopedic surgeons to decompress and stabilize the spine. These devices are implanted either from the front (anterior) of the spine, or from back (posterior). We cover anterior implants below:

The goals of cervical spine surgery include:

  1. Reduce pressure on the nerve(s) by decompression (for example, surgically removing tissues pushing on a nerve).
  2. Stabilize the cervical spine by fusing to or more cervical vertebrae together.

Anterior Cervical Approach Implants

Interbody Cages or Spacers

Spacers and cages are placed between two vertebrae. Their purpose is to:

  1.Maintain space between vertebrae (if the space gets too narrow, nerve roots can be pinched).

  1. Preserve spinal alignment (for example, a healthy neck has a specific curve; a spacer can help restore this curve) and/or,
  2. Promote spinal fusion (for example, join (fuse) two or more vertebrae together).

Cages (an orthopedic implant) is available in different sizes and shapes from Top Orthopedic Implants Manufacturers In India; some are cylinder-shaped and others box-shaped. Cages are placed or fit into the spine between vertebrae. Often cages are made from bone, plastic, metal, or carbon fiber. Bone chips (allograft, autograft, other bone graft substitutes, or other bone growth stimulating substances (for example, demineralized bone matrix) may be packed into the cage. During the months after surgery, the hope is the cage will allow and enhance fusion between the vertebrae below and above. Fusion increases stability of spine.

Spacers are solid devices and bone can’t be packed inside. A spacer is used to help restore or correct spinal alignment.

Anterior Cervical Plates are attached to the front of two or more vertebrae. Plates help to:

  1. Increase stability of cervical spine immediately after surgery.
  2. Stabilize the cervical spine while healing.
  3. Increase the chances for a successful solid fusion.
  4. Help to reduce the time the patient may require wearing a cervical collar after surgery.

Plates are made with screw holes through which bone screws are placed into the adjacent (to be fused) vertebral bodies to anchor the plates into proper place. Both screws and plates come in different sizes and designs. Most plates are made from metal (mostly titanium); some are made from plastics. Certain newer plates are made from composite materials that dissolve after fusion occurs. Some designs of plate are self-compressing to help promote spinal fusion.

Artificial Cervical Discs: Spine surgeons of the world are interested in cervical artificial discs to treat degenerative disease. It is believed maintaining movement between vertebrae is better than spinal fusion. Early studies report cervical artificial discs may help slow down the procedure or prevent adjacent level disc degeneration. The procedure is called disc arthroplasty. artificial discs are made from various materials. Some designs are all metal and others plastic and metal composites. There are several ongoing FDA trials of artificial discs underway in the United States; some completed while others still going on. Devices are being cleared for sale and implantation if the studies demonstrate efficacy and safety compared to fusion in selected cases.

Conclusion

It is encouraging that cervical decompression and stabilization procedures are some of the most successful operations spine surgeons perform nowadays. Patients usually have rapid recovery and quickly return to activities of daily living with marked improvement of their symptoms.
