SPINAL STENOSIS | DrBurke

Definition of Spinal Stenosis

Spinal stenosis is a disease of the spinal cord that is closely associated with arthritis. Stenosis is derived from the ancient Greek meaning ‘to constrict’ or ‘to narrow’. Spinal stenosis is then defined as the narrowing of the spinal canal. The spinal canal allows for passage of the spinal cord which provides nourishment to the lower back and lower limbs. Narrowing of the spinal space causes irritation and sometimes destruction of the spinal nerves. This, then results in a wide range of symptoms, arthralgia (joint pain) and arthritis (joint inflammation) being one of the major symptoms.

Causes of Spinal Stenosis

Spinal stenosis is one of the most common forms of arthritis. The causes include:

  • Age > 50 years – this accounts for 50% of cases
  • Thickening of the spinal ligaments
  • Overgrowth of the vertebral bones
  • Spinal tumors
  • Spinal injury
  • Congenital spinal stenosis
  • Scoliosis
  • Comorbid arthritis e.g. Paget’s disease, Ankylosing spondylitis, osteoarthritis etc.
  • Elevated circulating calcium
  • Herniation of the vertebral disc

Symptoms of Spinal Stenosis

The most prevalent site of spinal stenosis is the lumbar section.  It accounts for more than 65% of all cases of spinal stenosis. Other sites that are less common include: the cervical section and the thoracic section.

  • Pain in the lower back. Occasional pain in the middle and upper back.
  • Pain that is intense, cramping and excruciating
  • Severe disabling pain interrupting daily activities e.g. bending, climbing a few stair cases

  • Joint pain especially spinal and sacroiliac with or without joint inflammation
  • Numbness and weakness in the legs
  • Extreme feet numbness causing foot drop syndrome
