Anterior Disc Replacement

(ADR)

RELIEVE PRESSURE. RELIEVE PAIN.

Anterior disc replacement surgery is also a minimally invasive procedure that we perform to relieve the pressure on your spinal cord or nerves that may be causing pain, numbness, and weakness. We typically recommend this procedure for patients who have a cervical disc herniation or cervical degenerative disc disease that has not responded to non-surgical treatments.

 

The benefits of cervical disc replacement surgery include:

  • Maintaining normal motion in the neck
  • None of the complication or issues sometimes associated with a bone graft or fusion
  • A reduced chance of degenerative disc disease in adjacent cervical joints

Indications

An ADR is considered when there has been severe damage to a cervical spine disc as a result of osteoarthritis or a herniated disc. While the reasons for disc replacement are very similar to the reasons for Anterior Disc Fusion, there are some important differences:

  • Stricter criteria are used to indicate patients for disc replacement
  • The facet joints must be relatively healthy and should not exhibit hypermobility
  • The disease process should involve only the disc

The Procedure

The Sierra Spine doctors perform the ADR procedure using a minimally invasive technique where a small incision is made in the front (anterior) and to the side of the neck. This approach lets us access the disc without disturbing the neck muscles and uninvolved spinal nerves.

 

After we remove the damaged disc, we will smooth away any bone spurs and then place and anchor an artificial disc in the empty space that is left. We then close the incision and covers it with a dressing.

 

You will then be moved to a recovery room where you will be monitored for the next few hours. After you have recovered, you will be sent home with post-op instructions. Your doctor may also recommend you wear a soft collar for a short period of time to add support to your neck.
