Herniated Discs

Each vertebra in the spine is separated by a disc. These discs are composed of a tough fibrous outer ring (annulus fibrosus) and a gel-like center (nucleus pulposus). Functioning much like shock absorber, they spread out the weight-bearing forces in the spine.

If the outer ring gets damaged, one of two things can happen:

How does a herniated disc happen?

As we age, our discs weaken. When this happens, repetitive stress or injury may cause damage to one or more discs. The gel center may then bulge out of the damaged fibrous ring and put pressure upon the spinal cord, nerves, or other sensitive tissues. When this happens, you may experience pain or symptoms such as weakness, numbness, or tingling.

How is a herniated disc diagnosed?

To diagnose a herniated disc, your physician will review your health history and perform a physical examination.

Your doctor may also recommend diagnostic imaging such as an X-ray, MRI, or CT scan. Electromyography (EMG) testing may also be used to assess nerve signals.

How are herniated discs treated nonsurgically?

Fortunately, despite the pain associated with a disc herniation, symptoms can often improve on their own with supportive treatments.

Nonsurgical treatment options for herniated discs include:

What are the surgical treatment options for herniated discs?

If conservative treatments are ineffective, surgery may be considered. Surgery is reserved only for the cases where everything else has been tried or the limb weakness is so severe that you cannot do the most basic of daily activities.

Surgical treatments for herniated discs include:


The most common surgery for herniated discs is called a “microdiscectomy.” In this surgery, a one- to two-inch incision is made in your spine on the side of the herniation. The surgeon then finds the herniation and cuts it out. The surgery usually lasts about one to two hours, and many people feel better right upon waking up.

Disc replacement surgery

Disc replacement is most effective when the source of the pain is contained in the disc and the disc alone, and when the patient meets other qualifications, including a healthy weight, no prior major spine surgery, and no deformity in the spine.

Cervical discectomy and fusion

Anterior cervical discectomy with fusion is a surgical procedure that involves relieving the pressure placed on nerve roots and/or the spinal cord by a herniated disc or bone spurs in the neck.

How is an ACDF performed?
Through a small incision made near the front of the neck, the surgeon:

The goal of laminectomy is to relieve the pressure on the spinal nerves that is causing your symptoms.

How laminectomy works:


A foraminotomy is another kind of decompression surgery that aims to reduce the pressure on your spinal nerves. The surgeon makes more room for the nerves by enlarging the opening the nerves travel through on their way out of the spinal canal.
