What happens to the disc with injury or age?

With injury or age, these discs can become damaged, and the supporting ligaments surrounding them weaken. One of the reasons we lose height as we age is that the intervertebral discs lose their water content. This leads to shrinkage of the disc and, as a result, height diminishes.

What is a discogram used for?

An injured disc can be a source of pain. A discogram is used to determine if a particular disc is the source of pain. Discograms are provocative tests, meaning that they attempt to reproduce rather than remove pain. The reproduction of pain during a discogram can help determine if injury to a particular disc is the source of a person's pain.

How is a discogram performed?

When performing a discogram, a needle is inserted into the disc and a contrast dye is injected. This extra fluid in the disc increases the pressure in the disc. Patients with an injured disc may then experience pain that can mimic the pain they have been experiencing. The intensity of the pain is recorded on a 0-10 scale. Based upon this information, the diagnosis of a particular disc injury can be made. The doctor can then determine what the optimal treatment options are for relief of the underlying pain.

What happens after the procedure?

Patients may be sore for several days after the procedure. Any discomfort can be treated with the local application of ice packs or with a cooling pad on and off for periods of twenty minutes.
