Cervical Disc Herniation

Neck pain is part of everyday life for millions of adults. For many people it is just irritating, but for others it can be disabling, affecting their neck, shoulders and even their arms. While there are numerous conditions that can result in this type of pain, a common cause is a herniated disc. At the San Diego Center for Spinal Disorders (SDCSD) we are experienced with treating herniated discs both non-operatively and operatively.

The Basics
Discs, which act as shock absorbers for the spine, are located in between each of the vertebrae in the spine. Each disc contains a tire-like outer band (called the annulus fibrosus) that surrounds a gel-like substance (called the nucleus pulposus).

A herniation occurs when the outer band of the disc breaks or cracks and the gel-like substance from the inside of the disc leaks out, placing pressure on the spinal canal or nerve roots. In addition, the nucleus releases a chemical that can cause irritation to the surrounding nerves causing inflammation and pain.

How Do Discs Herniate?
Most cervical disc herniations occur as a result of sudden stress. This occurs during movements resulting in sudden flexion, extension, or twisting of the neck, such as during a fall or auto accident. Sometimes they occur gradually, over weeks or months. There are risk factors that can contribute to the chances of a disc herniation, including:

• Aging. As we get older, discs gradually dry out, affecting their strength and resiliency.
• History Major or minor trauma to the cervical spine.
• Lifestyle choices. Lack of regular exercise, not eating a well-balanced diet, and tobacco use substantially contribute to poor disc health.
• Poor posture, incorrect and/or repetitive lifting or twisting can place additional stress on the cervical spine.

Diagnosis
Good treatment is always based on an accurate diagnosis. Our comprehensive diagnostic process includes:

• Medical history. We will talk to you about your symptoms, how severe they are, and what treatments you have already tried.
• Physical examination. You will be carefully examined by one of our spine specialists for limitations of movement, problems with balance, and pain. During this exam, we will also look for loss of reflexes in the extremities, muscle weakness, loss of sensation or other signs of spinal cord damage.
• Diagnostic tests. Generally, we start with plain x-rays, which allow us to rule out other problems such as infections. CT scans and MRIs are often used to give us three-dimensional views of the cervical spine and can help detect herniated discs.

Symptoms
Symptoms of a cervical disc herniation may include the following:

• Dull or sharp pain in the neck or between the shoulder blades, which can intensify in certain positions or after certain movements.
• Pain that radiates down the arm to the hand or fingers (this is called radiculopathy).
• Numbness or tingling in the shoulder or arm.

Treatment for Cervical Disc Herniation
Most cases of cervical disc herniation do not require surgery. There are a number of non-surgical treatments that can help relieve symptoms. These include the following:

• Pain medications such as anti-inflammatories to reduce swelling and pain, muscle relaxants to calm spasm, and other medications to alleviate acute pain.
• Heat/cold therapy, especially during the first 24-48 hours.
• Physical therapy exercises such as gentle massage, stretching, and neck bracing or traction to decrease pain and increase flexibility.

At the SDCSD we are well equipped to provide all of the non-operative treatments described above. We are closely affiliated with outstanding physical therapy resources in the same building as our practice, our medical staff are able to provide expert education about such issues as healthy posture, good body mechanics, and suitable exercises.

Surgical Options
If non-surgical measures do not work, we may recommend surgery to treat your disc herniation. At SDCSD we have a new, state-of-the-art surgery center in the same building complex as our practice, and your surgery may be done here.

An anterior (from the front) cervical discectomy is the most common surgical procedure to treat damaged cervical discs. The goal of this procedure is to relieve pressure on the nerve roots or on the spinal cord by removing all or part of the damaged disc.

During the surgery, the soft tissues of the neck are separated to expose the offending disc. The disc is removed to decompress the spinal cord or nerve roots. If necessary, the space left by the removed disc will be filled with a bone graft. The bone graft may be obtained from the bone bank or from the patient's own hip, depending on the specific situation. The bone graft is used to join or fuse the vertebrae together. This is called a fusion. In some cases, some instrumentation (such as plates or screws) may be used to help promote fusion and to add stability to the spine.

During posterior cervical surgery, a portion of the bone covering the nerve may also need to be removed. This procedure is called a laminotomy.

Fortunately, these procedures can often be done utilizing minimally invasive techniques. Minimally invasive surgery uses smaller incisions and specialized instruments such as microscopes and endoscopes. We use minimally invasive techniques only when we are convinced that the surgical outcome will be as good or better with a minimally invasive technique, as compared to a traditional open technique.

Recovery
Most of our patients at SDCSD can begin getting out of bed on the same day surgery is performed! Activity is gradually increased and patients are typically able to go home within 1 - 2 days after their procedure, depending on the extent of the surgery. As with most surgeries, there will be some pain after the procedure. However, the staff at our practice is very attentive to patients' pain levels, and we have considerable expertise at minimizing pain and discomfort using pain medications and other modalities.

At home, you will need to continue to rest. You will be instructed on how to gradually increase your activity. You may still need to take the pain medications for a while. However, pain and discomfort should begin to reduce within a week or two after surgery. Other techniques for reducing pain and increasing flexibility will be discussed with you before you leave for home. When you can return to work and other activities such as sports and driving will also be discussed with you before you leave.

Your health is our primary concern
At SDCSD we want you to return to an active, pain-free lifestyle. Our team of medical experts, including our affiliated physical therapy team, will work with you over the long-term to ensure a complete and successful recovery.
