What Are the Symptoms of Cervical Spinal Stenosis?
Patients with cervical spinal stenosis may have the following symptoms:
- Tingling, pain or numbness that originates in the neck and extends down the arms
- Loss of control over the arms (called spasticity) that can lead to the inability to hold objects
- Numbness in arms
- Loss of position sense, meaning the inability to know what position arms are in if they are not visible.
- With major weakness or loss of bladder or bowel control, seek help immediately as this could signal a serious problem
What Are the Causes of Cervical Spinal Stenosis?
The natural aging process is far and away the main cause of spinal stenosis. Osteoarthritis is the most common cause of cervical spinal stenosis. The gelatinous discs that cushion the vertebrae in the spine begin to dry out as we age, resulting in shortened disc height. This puts pressure on the facet joints. As they feel more pressure, they too deteriorate, leading to arthritis. The arthritis can cause the ligaments around the joints to thicken and enlarge, decreasing space in the spinal canal for nerves to pass through. The cartilage that protects joints wears away as well. Too much wear leads to bone-on-bone rubbing. To compensate for the missing cartilage, the body may grow bone in the facet joints. Bone overgrowth is called spurs, and their formation further contributes to the narrowing of space in the spinal canal for nerves to pass through. Once the space within the spinal canal becomes too cramped, pain can ensue.
Cervical spinal stenosis can also be caused by other conditions as well. Those include:
- Spondylosis or spondlylolisthesis (slipped disc)
- Injury or fracture
- Rheumatoid arthritis or ankylosing spondylitis
- Metabolic conditions such as Paget’s disease or fluorosis, an excessive level of fluoride in the body.
What Are the Treatments for Cervical Spinal Stenosis?
Dr. Singh first uses conservative, non-surgical treatments for cervical spinal stenosis. Non-surgical treatments, however, do not correct spinal narrowing. Instead, the treatment options for cervical spinal arthritis and cervical spinal stenosis are aimed at controlling pain and improving quality of life for some patients. Some treatment options include:
- Nonsteroidal anti-inflammatory drugs to reduce swelling
- Physical therapy to increase flexibility
- Spinal steroidal injections or “blocks”
If a patient does not improve after non-surgical treatment, Dr. Singh may suggest surgery as a solution for cervical spinal stenosis. The goal of the surgery is to open the spinal canal to give nerves adequate space. There are two primary kinds of surgery to treat cervical spinal stenosis, depending on whether or not the patient has coexisting instability (abnormal movement) or deformity (abnormal alignment of the spine):
