What is a Herniated Disc?

A herniated disc has often described by patients as a "bulging disc, ruptured disc or a slipped disc.” These descriptions can be misleading and should be better understood. One of the most common causes of low back and leg pain is a lumbar herniated disc. Lumbar discs are made up of a tough interwoven like fabric called the annulus fibrosus and an inner cotton/get-like center called the nucleus pulposus. The discs are located between each vertebrae and serve a role as a shock absorber.

The bones (vertebrae) that make up your spine are cushioned by sponge-like disc. When these disc are healthy they keep our spine flexible acting as shock absorbers. When they become brittle or degenerative, the inner sponge (nucleus) may push against the outer annulus causing a tear and begin to bulge, rupture (herniated disc) or in worst cases cause the vertebral bodies to slip (spondylolithesis). A herniated disc can happen in the neck (cervical spine) middle of the back (thoracic spine) or most commonly in the lower back (lumbar spine).

What Causes a Herniated Disc?

Our spine and disc take a lot of stress over time. Most herniated disc’ are a result of a trauma or an accident putting direct stress on the disc. Gradually over weeks or months the outer annulus develops cracks and the inner gel-like nucleus is pushed out to become a bulging disc. When this occurs the disc puts pressure on the spinal cord (dura) and or nerve roots that branch our at each level and travel down your legs connecting to your muscles. A bulging disc is not always symptomatic. However, when the annulus becomes brittle and tears that bulging nucleus can protrude (ruptured disc) and extrude (herniated disc) or leave the disc entirely called sequestered disc. With time that herniated disc can become more pronounced and put significant pressure on the spinal nerves. This pressure and nucleus fluid that leaks out causes inflammation and pain sometimes localized to the back, buttock, thighs and sometimes all the way down into your calves and feet.

The following risk factors can contribute to herniated disc:

  • Aging: As we age our discs gradually dry out losing its strength and structural integrity.
  • Lifestyle: Not maintaining a well balanced diet, lack of regular exercise, over weight and smoking contribute to poor disc health
  • Posture: Poor mechanics when lifting or twisting puts additional stress on the spine and disc.

What are the Symptoms of a Herniated Disc?

The following symptoms are associated with a herniated disc:

  • Sharp or dull pain in the lower back which gets worse with physical activity such as lifting, bending, or as simple as coughing or sneezing, muscle spasms or cramping.
  • Sciatica (pain, burning, tingling, and numbness that extends from the buttock into the leg or foot).
  • Leg weakness or loss of leg function.
  • Loss of control of bowel or bladder function – Can be due to cauda equine syndrome or herniated disc and is considered a medical emergency. Seek medical attention immediately

How Long Is The Recovery?

Our Least Invasive Procedure patients’ can begin getting out of bed one hour after surgery and go home shortly afterwards. There will probably be some pain after the procedure and is usually localized to the incision site. Activity is gradually increased and patients can return to non-physical work as early as two weeks. Keep in mind just because there is less or no pain, always consult your physician before beginning any physical work.

Our Minimally Invasive Spine Surgery patients’ post-operative recovery is much longer and may involve overnight stay in the hospital. Once your pain in under control you can go home. Dr. Rodriguez will give you medication to control your pain while you recover at home.

At home, you will need to continue to rest. You will be instructed on how to gradually increase your activity. You may still need to take the pain medications for a while. However, pain and discomfort should begin to reduce within a couple of weeks after surgery. The doctor will discuss with you other techniques for reducing pain and increasing flexibility before you leave for home. MIS patients can return to non-physical work as early as four to six weeks. Spine fusion patients can return to non-physical work as early as two to three months.
