Spinal Stenosis

Spinal Stenosis is the narrowing of openings within the spinal canal through which the spinal cord and nerve roots pass.


What is Spinal Stenosis?

Spinal Stenosis is the narrowing of openings within the spinal canal through which the spinal cord and nerve roots run. Stenosis causes pressure on the nerves and spinal cord resulting in a multitude of symptoms. It may affect various parts of the spine.

Lumbar Stenosis Symptoms

  • Sciatica
  • Pain that radiates from the lower back down the buttocks and legs
  • Leg pain
  • Pain or cramping when standing or walking,usually alleviated by bending forward or sitting down
When looking at a normal spine, there is enough room for the nerve roots to slip through the bony channels. However, the spinal canal can become clogged with debris from bone spurs, disc bulges and disc herniations as we age, trapping and compressing nerves.

Although not all stenosis cases are critical, if ignored, loss of function may occur if nerves die or become irreversibly damaged.

Lumbar Stenosis causes nerve roots to the spine to become compressed, resulting in symptoms of sciatica; it accounts for 75% of all stenosis cases.

Cervical (Forminal) Stenosis Symptoms

  • Numbness
  • Weakness
  • Sensations of burning, tingling, and pins and needles in the affected extremity (arms, legs, feet, hands)
  • In severe cases, compression of nerves leading to the bladder and bowels may be involved, causing incontinence
Cervical, or Foraminal, Stenosis is a condition that progresses slowly and involves pinching of the spinal cord in the neck. Due to the fact that Cervical Stenosis involves compression of the spinal cord itself, as opposed to compression of the nerves, it is considered the more dangerous of the two. If untreated, severe cases may result in loss of motor control and paralysis.
