Spinal Instability and Spinal Stenosis

Spinal instability


Spinal instability is the abnormal movement of the spinal column under normal conditions. Spine provides support, structure and protection to whole body. An unstable spine loses all its functions and integrity. As disc between vertebrae splits, it loses tension and thereby causing abnormal movement of the vertebrae. This affects the nearby nerve. Thus pain is induced in the back and leg region. Abnormal spine column may be a result of trauma, spinal injury, or degenerative spine disease.


The common symptoms of spinal stability are:

  • Acute pain in buttock, leg and back.
  • Permanent neurological disorders such as loss of sensation or paralysis.
  • Compression of spinal cord.


Depending upon the cause and severity of condition, the treatment method varies. For mild or moderate symptoms, conservative treatment procedures are opted. They include rest, wearing of brace and physical therapies. Surgical treatment is mainly used to treat trauma caused instability or congenital instability

Spinal Stenosis:


With age, changes start to occur in shape or size of spinal canal. One such change is narrowing of spinal canal. This disease condition is known as spinal stenosis. The lower back or neck region is most commonly affected, thus causing pressure on the spinal cord or nerves. Severe pain is experienced in legs, lower back or calves. Females are more prone to spinal stenosis. Other than aging, the common causes of spinal stenosis are:

  • Development of bone spurs
  • Osteoarthritis
  • Spine surgery or injury
  • Paget’s disease.


Unlike disc prolapsing, spinal stenosis is a chronic condition. The various symptoms include:

  • Shooting pain in back, neck and legs
  • Burning sensation, numbness and tingling
  • Discomfort in standing and walking


The complete cure of spinal stenosis is not possible. Only pain management and control of symptoms can be done. For treating initial stages of pain, conservative methods are the best option. They include medication, cortisone injections, rest, and physiotherapy.

In severe cases, surgical methods are chosen. They may be:

  • Decompression Surgery
  • Spinal Fusion Surgery
  • Interspinous Process Spacer
