Introduction to Herniated Discs
Herniated DiscA disc is composed of two parts: an outer rim of fibrous (tough) tissue surrounding an inner loose material.
When there is a break in the outer rim, the inner material can leak out of the disc space and enter the spinal canal where the disc material can compress nerve roots or the spinal cord.
Disc herniation is a common cause of leg and back pain.
Symptoms of a Herniated Disc
The first symptom is usually extreme, sudden pain. In most cases the bottom two discs in the spinal column are the ones that herniate, so the pain usually begins in the lower back. When they bulge, these two discs exert pressure on the sciatic nerve, causing sharp pain to shoot down the leg. Sciatica will affect as much as 40% of the adult population at some point in their lives.
Herniated discs higher up in the spine can cause pain and weakness in the neck, shoulders, or arms.
Numbness and tingling in twoes and fingers, as well as a loss of movement or strength in any part of the body are also symptoms of a herniated disc and could be a sign of a serious problem. It’s important to note that pain is often not a matter of a single defect.
The pain associated with disc herniation usually improves with lying down and worsens with prolonged sitting/standing or walking. Rarely, bowel or bladder problems and progressive neurological deficits (such as weakness) may develop; this type of situation requires urgent surgical decompression of the nerves under pressure.
A magnetic resonance image (MRI) is an excellent tool to diagnose a herniated disc. If previous surgery has been performed in the area, however, a special MRI with contrast, or a CT myelogram is the most effective way to evaluate the spine. X-rays are also routinely used to determine the bony anatomy and alignment of the spine.
Treatment Options for Disc Herniation
Because there are so many causes of a herniated disc (and all back pain for that matter), each patient commands a different treatment plan. The first approach we take with all our patients is conservative, with treatment consisting of exercise, physical therapy or medication (or a combination therof). The majority of back problems go away in four to six weeks with moderate medical attention and pain medication. For those who fail conservative treatment there are now new microsurgical techniques that can offer appreciable relief.
Most people have full recovery from episodes of sciatica within the first few weeks. If the symptoms continue past 6 weeks, however, one should consider undergoing an evaluation which includes MRI studies.
If symptoms continue and conservative management has not been helpful, surgical decompression of the disc (microdiscectomy) may be helpful in relieving the symptoms. The only absolute indications for surgery, however, are progressive neurological symptoms, bowel or bladder problems, and severe, unremitting pain.
Conservative Treatments Options: |
- Medications (medicines are available to help control pain)
- Acupuncture (an adjunctive treatment for the relief of chronic or acute pain)
- Body Braces (a medical device designed to support the body and to correct spine curvature)
- Physical Therapy (therapist guides the exercise process, stretching the muscles along the spinal column while the patient is in the specified positions)
Surgical Treatments Options:
- Artificial Disc Replacement (total disc replacement)
- Spinal Fusion (remove the disc and fuse the vertebre together)
- Microendoscopic Discectomy (MED) (is performed by making a small incision in the patient’s back and inserting a small endoscopic probe between the vertebrae)
- Laminaplasty (procedure is used to relieve spinal cord compression in the cervical spine)
