Cervical Spinal Stenosis
Cervical stenosis is a relatively common condition. However, the symptoms, which can include neck pain, weakness or numbness in the shoulders or arms, and clumsiness with hands, can be quite alarming for patients. At the San Diego Center for Spinal Disorders (SDCSD), we have extensive experience treating this condition, and have a history of successful results.
Cervical stenosis is a narrowing of the spinal canal in the neck area or upper part of the spine. This narrowing places pressure on the spinal cord. While some patients are born with this narrowing, most cases of cervical stenosis occur to patients over the age of 50 and are the result of aging and "wear and tear" on the spine.
Many patients with cervical stenosis have a history of some kind of injury or trauma to the neck, however this trauma may have occurred many months or even years before the onset of stenosis symptoms.
Symptoms of Cervical Stenosis
The symptoms of cervical spinal stenosis may include the following:
- Neck pain; not always severe.
- Pain, weakness, or numbness in the shoulders, arms, and legs.
- Hand clumsiness.
- Gait and balance disturbances.
- Burning sensations, tingling, and pins and needles in the involved extremity, such as the arm or leg.
- In severe cases, bladder and bowel problems.
- Although rare, severe cases can also cause significant loss of function or even paraplegia.
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 tumors and infections. CT scans and MRIs give us three-dimensional views of the cervical spine and can help detect osteophytes (bony growths) and herniated discs. In some patients we may use myelograms. This is a test that involves the use of a liquid contrast dye that is injected into the spinal column to show where the spinal cord pressure is occurring.
Treatment of Cervical Stenosis
Most cases of cervical stenosis are successfully treated with non-surgical techniques such as pain and anti-inflammatory medications. Depending on the extent of nerve involvement, some patients may need to temporarily restrict their activities and wear a cervical collar or neck brace for a time. However, most patients only need to rest for a brief time. Physical therapy exercises will also be prescribed to help strengthen and stabilize the neck as well as build endurance and increase flexibility. At SDCSD, our patients receive physical therapy from a group of expert physical therapists in the same building as our practice's office.
If these non-surgical measures do not work, we may recommend surgery to treat your stenosis. At SDCSD, it is likely that your surgery would be performed at our new, state-of-the-art surgery center, in the same building complex as our practice.
There are a number of surgical techniques that we can use to treat this condition. The goal of each of these surgical decompression treatments is to widen the spinal canal and relieve the pressure by removing or trimming whatever is causing the compression. However, since all surgical procedures carry a certain amount of risk, we will discuss all of your options with you before deciding which procedure is best for you.
The most common surgery for cervical stenosis is called a decompressive laminectomy in which the laminae (roof) of the vertebrae are removed, creating more space in the spinal canal for the nerves. If only a portion of the laminae need to be removed, it is called a laminotomy. Your surgeon may also consider performing a posterior laminoplasty. This technique helps to retain spinal stability while also expanding the spinal canal. If there are any herniated or bulging discs, these may also be removed (this is called a discectomy) to increase canal space. Sometimes the foramen (the area where the nerve roots exit the spinal canal) also need to be enlarged. This procedure is called a foraminotomy.
For those patients who need surgical repair on more than one level or who have significant spinal instability, spinal fusion may be done in addition to the decompression surgery. This involves taking a small piece of bone (taken from the hip or obtained from the bone bank) and grafting it onto the spine. Spinal implants (called instrumentation) such as plates and screws are used to support the spine and provide additional stability. In most cases, we can determine ahead of time if fusion surgery is necessary. If it is, we will discuss this with you ahead of time so that you are aware of what is being done.
At SDCSD, most patients can get out of bed on the same day surgery is performed. Activity is gradually increased and patients are typically able to go home within a few days after their procedure, depending on the extent of the surgery. As with most surgeries, there will be some pain after the procedure. However, we have pain medications available that will help keep you comfortable. You can be assured that our staff takes pain management very seriously.
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.
