herniated disc los angelesDegenerative disc disease, while one of the more common sources of chronic back and neck pain, remains one of the more difficult spinal conditions to treat effectively. As we age, discs between bones of the spine (vertebrae) can become damaged, begin to degenerate and ultimately contribute to spinal instability. Currently, the standard surgical treatment for symptomatic degenerative disc disease is spinal fusion in which two or more vertebrae are permanently fixed together as a single unit. This procedure can have notable disadvantages, including limited flexibility, altered biomechanics of the spine, and potential for degeneration of discs above and below the fusion.

Disc replacement is a cutting-edge alternative to spinal fusion that involves replacing a damaged disc with an artificial implant which closely mimics the stability and shock absorbing properties of a healthy spinal disc. By avoiding fusing multiple vertebrae together, disc replacement preserves the natural flexibility and biomechanics of the spine while relieving pain due to spinal instability.

What is an Artificial Disc?

Efforts to create a safe, durable, and functional artificial disc began in the early 1960s. In the past 50 years, the design of artificial discs has improved dramatically, making disc replacement the treatment of choice for many patients requiring surgical stabilization.

An artificial disc is a composite structure, composed of rigid metal endplates and a polyethylene or rubber spacer in between. With the endplates securely fixed to vertebrae above and below, the flexible spacer provides cushion and enables all the complex range of motions of a natural spinal disc. An artificial disc can be easily monitored through X-ray imaging and is built to support normal daily activities for up to 50 years. The materials used are similar to those used in hip and knee replacements, and are designed not to cause irritation or sensitivities.

Who is a Candidate for Disc Replacement?

Before performing surgery, Dr. Gravori carefully assesses each patient’s condition to ensure that the most appropriate surgical technique is used. Patients typically must meet the following criteria to be eligible for disc replacement:

  • Back pain and/or spinal instability attributed to disc degeneration
  • No significant bony compression of nerves
  • No major spinal deformity (scoliosis)
  • Not excessively overweight

How Does Disc Replacement Work?

Dr. Gravori is among a select group of physicians trained to perform artificial disc replacement in both the neck and the lower back. Depending on the patient’s condition, disc replacement surgery may be performed from the side (lateral) or front (anterior) of the spine. The first step of surgery is to remove the damaged disc (complete discectomy). The vertebrae above and below are then spread apart slightly and the artificial disc is inserted into the vacated disc space, with the metal endplates securely fixed into the vertebral surface. Overtime, bone will naturally grow around the metal plates and provide additional stability to the implants. Finally, the incision is closed with sutures.

Recovery time following disc replacement may vary from one to several days after surgery, depending on the health of the patient, surgical technique, and the location of the replaced disc. Generally, there is less pain and fewer complications associated with disc replacement compared with traditional spinal fusion.
