Lumbar Disc Herniation

The lumbar spine (lower back) is composed of vertebrae bodies and disc (cushions) between each body. The disc consists of an outer rim of strong collagen or connective tissue (annulus) and an inner core of a gel like material called the nucleus. As the Lumbar disc degenerates (ages), a tear of the outer layer (annulus) can occur because of a minor or more severe trauma such as an accident, stressful sports, heavy lifting, or bending, and even simple activities of daily life.

When this happens, a piece of the inner gel or nucleus may herniate from the disc causing sudden (or acute) back pain or leg pain (sciatica). This is commonly known as a slipped disc or herniation disc.

If part of the gel-like nucleus contracts, it can cause a chemical inflammation response or herniated disc. Symptoms can include buttock pain, radiation of pain down the leg, numbness and tingling and weakness.

Most patients (80%-90%) respond to conservative treatment such as physical therapy and exercise, chiropractic, anti-inflammatory medications like Advil or Aleve and rest or reduction of certain physical activity. If leg pain remains severe (7-9/10) then epidural steroid injections can be of benefit.

If surgery is necessary when conservative measures fail to relieve symptoms, usually a simple minimally invasive procedure can be performed. Removal of the herniated piece of nucleus or gel will relieve leg pain in 90% of cases.
