Lumbar Disc Herniation

A herniated lumbar disc can press on the nerves in the spine and may cause pain, numbness, tingling or weakness of the leg called "sciatica." Sciatica affects about 1-2% of all people, usually between the ages of 30 and 50.

The spine is formed by 24 bones called vertebrae that are separated from each other by discs that protect against bone on bone friction and act as buffers to absorb the shock produced by almost any movement. The disc has an inner component called nucleus pulpous made up of a gel-like substance and an outer component called annulus fibrosus that contains the inner core in its place.


The integrity of the disc may be compromised by:

  • Aging
  • Trauma
  • Stress
  • Overweight
  • Smoking habit
  • Inheritance
Herniated Disc

Any of the above may cause alterations to the disc that cause a dehydration of the disc with loss of height, fissure of the annulus and ultimately a tear that protrudes the inner core, affecting the nerve roots and producing pain.

There are different stages or classifications of herniated discs.

Lumbar Disc Hernation


Symptoms include:

  • Discomfort in the lower back
  • Pain that travels down the leg or buttocks
  • Muscle spasms
  • Weakness
  • Diminished reflexes

In more serious conditions, it may affect bladder and bowel control. Symptoms may vary and one may be more prominent than the other. It is commonly diagnosed by a medical examination and confirmed with imaging studies.


In early stages, it may be treated conservatively with oral medication to control pain and muscle spasms. However, it usually is a surgical condition due to the worsening of the symptoms and the disability it produces. If you’ve been diagnosed with a herniated disc and have tried conservative measures or surgical without any success, you may benefit from our minimally invasive procedures.
