Spinal Stenosis

Spinal stenosis.

Stenosis is another word for “narrowing,” so if your Othopedist diagnoses you with spinal stenosis, it means the passage through which your spinal cord or nerves run is partially obstructed.  Houston Advanced Spine can treat stenosis using a variety of techniques.

Although spinal stenosis does not always result in symptoms, it can cause discomfort ranging from mild to debilitating. In severe cases, it can be difficult to walk even a moderate distance without pain. Stenosis can occur in two separate areas of the spine:

  • Stenosis of the spinal canal, which spans the length of the entire spine and houses the spinal cord
  • Stenosis of the intervertebral foramen, that is, the holes through which the nerves exit out of the spine to go to other areas of the body

Stenosis is common among adults over 50, affecting both women and men. Less commonly, people develop it when they are younger, typically due to an underlying condition such as a spinal injury.

Symptoms of Spinal Stenosis

he obstructions may or may not press on the sensitive nerves that fan out from the spinal cord. When nerves are irritated by pressure within the narrowing holes of the spine, it can cause a variety of symptoms that generally develop slowly. If left untreated, depending on its extent and severity, spinal stenosis can affect your daily routine. The most common places for spinal stenosis to occur are in your neck and lower back. Not everyone will have symptoms, but here’s what people with stenosis may experience:

Neck (cervical) stenosis

  • Neck pain, which may be mild
  • Burning pain, numbness or tingling in your upper extremities
  • Weakness in your upper extremities
  • Problems with balance and gait
  • Problems using your hands

Lower back (lumbar) stenosis

  • Burning pain in buttock or leg (sciatica) that may travel down to the foot
  • Back pain
  • Numbness or tingling in your buttock or leg
  • Weakness in your buttock or leg
  • The feeling that your foot is “slapping” the ground (foot drop)
  • Severe cramping of the calves when walking
  • Pain in the calves or legs that eases when you bend forward, sit or lie down

Causes of Spinal Stenosis

The most common cause of spinal stenosis is arthritis—wear and tear on the joints and discs of your spinal column. As you age, the cartilage that covers these joints is worn away in the same way that arthritis affects your knees or fingers. As the cartilage deteriorates, your body may grow new bony material to try to support the joints, known as bone spurs. The spurs don’t always cause problems, but when they grow in such a way that they compress a nerve, it can be very painful and may require surgical intervention.

Your body may also try to compensate for the loss of cartilage by increasing the size of the ligaments that connect your joints in your lower back. As they take up more space, they reduce the diameter of the spinal canal.

Bulging or slipped (herniated) discs or an abnormal curvature of the spine (scoliosis) can also cause spinal stenosis.
