Spinal Stenosis
What Is Spinal Stenosis?
Spinal stenosis is a narrowing of the open spaces within the spine that can put pressure on the spinal cord or the nerves that branch out from it. This narrowing most often affects the neck (cervical spine) and lower back (lumbar spine), but it can occur in other regions of the spine as well.
Spinal stenosis is commonly related to age-related changes in the spine, including disc degeneration, bone spurs, thickened ligaments, or arthritis in the joints of the spine. In some cases, prior injury, surgery, or other conditions can also contribute. Because spinal stenosis can affect the nervous system, early evaluation and treatment are important when symptoms appear.
Types of Spinal Stenosis
Cervical Spinal Stenosis
Cervical spinal stenosis occurs in the neck region. The spinal canal narrows and can compress the spinal cord or the nerve roots where they exit the spine. This may cause neck pain, shoulder or arm pain, hand weakness, loss of dexterity, numbness or tingling, and difficulty with coordination or balance. In more severe cases, bowel or bladder function may be affected.
Lumbar Spinal Stenosis
Lumbar spinal stenosis occurs in the lower back and is the most common form of spinal stenosis. It can cause lower back pain, leg pain or cramping (often called sciatica), numbness or tingling in the legs or feet, and difficulty walking or standing for long periods. Symptoms often worsen with standing or walking and improve when sitting or bending forward.
Common Symptoms
Symptoms vary depending on where the stenosis occurs but may include:
- Neck or back pain
- Numbness or tingling in the arms, hands, legs, or feet
- Weakness in the extremities
- Pain, heaviness, or cramping in the legs when walking or standing
- Problems with balance or coordination
If these symptoms develop or worsen over time, a medical evaluation is recommended. Your doctor may perform a physical exam and order imaging tests, such as X-rays or MRI, to confirm the diagnosis.
Nonsurgical Treatments
Many cases of spinal stenosis can be managed without surgery, especially when symptoms are mild to moderate. Treatment focuses on relieving pain, improving mobility, and protecting long-term spinal health.
Lifestyle Modifications
Simple changes can help reduce stress on the spine. These may include adjusting daily activities, avoiding positions that increase symptoms, maintaining good posture, and taking frequent breaks during prolonged standing or walking. A healthy weight and regular low-impact exercise can also lessen pressure on the spine.
Medications
Pain-relieving medications may be recommended to help manage discomfort. These can include over-the-counter nonsteroidal anti-inflammatory drugs (NSAIDs), or in some cases, prescription medications. Your doctor will choose the most appropriate option based on your symptoms and medical history.
Physical Therapy & Exercise
Physical therapy can help strengthen the muscles that support the spine, improve flexibility, and promote better posture and body mechanics. A customized exercise program may include stretching, core strengthening, and conditioning activities designed to reduce pain and improve walking tolerance.
Epidural Steroid Injections
For more significant pain or inflammation, epidural steroid injections may be used. These injections deliver anti-inflammatory medication into the space around the spinal cord and nerves, targeting areas of compression to reduce swelling and relieve pain.
Supportive Devices
In some cases, bracing can provide extra support and help limit painful motion. Walking aids, such as canes or walkers, may improve balance and reduce pressure on the spine, particularly for patients with lumbar spinal stenosis who have difficulty standing or walking.
Surgical Treatments
If nonsurgical treatments no longer provide relief and symptoms significantly impact daily activities, surgery may be considered. The goal of surgery is to relieve pressure on the spinal cord or nerves and improve stability when needed. The specific procedure recommended will depend on the location and severity of the stenosis.
Laminectomy
In a laminectomy, the surgeon removes the lamina—the back part of the vertebra—to create more space for the spinal cord and nerves. This is one of the most common procedures for spinal stenosis and can reduce nerve compression and pain.
Cervical Laminoplasty
Laminoplasty is a procedure commonly used for multilevel cervical spinal stenosis. Instead of removing the lamina, the surgeon reshapes and repositions it to enlarge the spinal canal, creating more room for the spinal cord while maintaining spinal stability.
Spinal Fusion
In some cases, vertebrae may be fused to provide stability after decompression surgery. Spinal fusion uses bone grafts and hardware such as screws, rods, or plates to permanently join two or more vertebrae. This eliminates motion at the affected level and can help prevent further nerve compression.
Your doctor will discuss the benefits and risks of each option and recommend a treatment plan tailored to your specific condition, overall health, and goals.
