What is lumbar spinal stenosis?

THIS POST IS PART OF THE ULTIMATE GUIDE TO BACK PAIN RELIEF

Lumbar stenosis is when the canal that carries the nerves through the lower back narrows. Lumbar spinal stenosis typically occurs as a result of aging and symptoms may develop slowly over time.

Anatomy

The spine is made up of 24 bones, called vertebrae, which are stacked on top of one another. These bones connect to protect the spinal cord. Muscles, ligaments, nerves and intervertebral discs are also part of your spine.

What causes lumbar spinal stenosis?

Arthritis refers to degeneration of any joint in the body and is the most common cause of spinal stenosis. As a spinal disc degenerates and loses water content arthritis can result.  The cartilage that covers and protects the joints begins to wear away.

If the cartilage wears away completely, it can result in bone rubbing on bone. To make up for the lost cartilage, your body may respond by growing new bone in your facet joints to help support the vertebrae. Over time, this bone overgrowth-called spurs-may narrow the space for the nerves to pass through.

Symptoms of lumbar spinal stenosis

  • Discomfort in your back, buttocks and legs
  • Pain, cramping or weakness when you walk
  • Less pain while sitting or leaning forward
  • Pain when running or golfing

Physician examination

To determine whether you have lumbar spinal stenosis, your physician will ask you for a complete medical history and conduct a physical examination. Other tests which may be ordered to confirm your diagnosis include: X-ray, MRI or in rare cases, a CT scan.

Pros and cons of back surgery

How is lumbar spinal stenosis treated?

Once someone develops pain from lumbar stenosis they most commonly tend to have that pain unless it is treated. Roughly 10 percent of patients may have a spontaneous recovery and another 20 percent may have some worsening over time. The remaining 70 percent tend to have symptoms that do not particularly improve or worsen over time. Developing a paralysis or nerve injury is very rare unless someone has severe narrowing around their nerves or had a sudden injury.

  • Oral steroids
  • Nerve medications
  • Over the counter pain medication
  • Spinal injections 
  • Physical Therapy exercises

Surgery

The surgeries for lumbar stenosis are very effective for reducing or eliminating the pain that stems from pressure on the nerves. Many patients choose surgery when they have not had relief from the other nonsurgical treatments. The most common surgery is called a laminectomy.   

Rehabilitation

Surgeons are different in their protocols for recovery. In general, it is acceptable to walk up to several miles a day immediately following surgery. Some physicians recommend a course of physical therapy and strengthening two weeks after surgery.  During this time, there are still limitations on bending, lifting and twisting. All restrictions are lifted approximately six weeks after surgery.
