The Spine, Disc Disease and Treatment

Disc replacement

The spine is made up of a series of bones called vertebrae, stacked on top of each other, running from your neck to your lower back.  Between these vertebrae are what we call discs, which act as a cushion for the vertebrae.

What happens when discs degenerate?

The discs in the spine can be damaged as a result of traumatic injury, which results in a herniation (a bulge or rupture) of the disc. This is typically marked by a sudden onset of pain, which can start in the neck and radiate down the arm, or pain in the back that can radiate down the leg.  More commonly, though, what we see is chronic degeneration. This can result from normal aging or overuse, and pain will typically increase over time.

As a disc continues to degenerate, the space between the bones narrows, causing pain in the back or neck. That loss of space also results in less space for the nerves that go to the arms and legs, which can cause that radiating pain to the arm or leg as the nerves are compressed.

Treating damaged discs

Normally most spine providers will recommend conservative treatment first. Non-surgical treatments can be very effective to treat the pain associated with this condition. The initial treatment options include:

  • medications such as anti-inflammatories
  • physical therapy to work on exercise that can address some of the pain and restore function
  • activity modification
  • weight loss, especially in chronic degenerative conditions
  • cervical traction, which is a device that can gently pull in line with the neck to take some pressure off the nerves

If pain cannot be managed through those treatment options, more invasive treatments may be appropriate. Steroid injections that target the area of pain or the nerve that is being compressed can also be considered. These injections can decrease the local inflammation around the nerve that is being compressed.

When all other treatments have failed, there are surgical treatments that can address the issue. The type of surgery varies from patient to patient and also by the location of the issue (neck versus back), but treatment options include removing the disc, replacing the disc, or performing a fusion.

Disc replacement

Great advances have been made in treating spine disease in recent years. We now have the technology to replace discs when they have become damaged. Through this procedure, the surgeon can remove the damaged disc material, especially in the areas where it is putting pressure on the nerves. An artificial disc implant can then be used to fill the space where the previous disc was removed. This implant can mimic the role and the motion of the normal disc and help keep the pressure off the nerves.

Disc replacements can be an approach to treating pain and disc degeneration for some individuals, but not everyone is a candidate for this procedure.

Fusion

Fusion is another type of procedure. For some patients, the degenerative changes in the spine may be so severe that disk replacement is not an option. Other patients may have instability between the bones, so preserving the normal motion is not an option.  These patients may be candidates for fusion, a procedure that allows the bones to grow together across the disc space. The idea is that by stopping the motion and getting the bones to grow together, we can eliminate some of that pain that occurs with the motion. Fusion can also be helpful if there are several locations within the spine that have degenerated.

What to expect after a disc replacement procedure

A routine disc replacement may sometimes be done as an outpatient procedure, or it may involve an overnight stay in the hospital. Patients are permitted to walk right after surgery and gradually resume activity. They should avoid excessive bending, lifting, or twisting in the initial postoperative period.

Preventing disc damage

Like so many aspects of our health, both genetics and lifestyle play a role in disc disease. Some people are predisposed to develop degenerative changes in their neck and back. Lifestyle factors and overuse can also accelerate the degenerative process. But there are modifications you can make to help keep your discs as healthy as they can be:
