Ruptured Disc (Herniated Disc) Information

Herniated disc facts

  • The discs are pads that serve as "cushions" between the vertebral bodies, which minimize the impact of movement on the spinal column.
  • Each disc is designed like a jelly donut with a central softer component (nucleus pulposus).
  • Abnormal rupture of the central portion of the disc is referred to as a disc herniation.
  • The most common location for a herniated disc to occur is in the disc at the level between the fourth and fifth lumbar vertebrae in the low back.
  • If the disc herniation is large enough, the disc tissue can press on the adjacent spinal nerves that exit the spine at the level of the disc herniation.
  • The physical examination, imaging tests, and electrical tests can aid in the diagnosis of a herniated disc.
  • Depending on the severity of symptoms, treatments for a herniated disc include physical therapy, muscle-relaxant medications, pain medication, anti-inflammation medications, local injection of cortisone (epidural injections), and surgical operations.

How are the spine and its discs designed?

The vertebrae are the bony building blocks of the spine. Between each of the largest parts (bodies) of the vertebrae are the discs. Ligaments are situated around the spine and discs. The spine has seven vertebrae in the neck (cervical vertebrae), 12 vertebrae in the mid-back (thoracic vertebrae), and five vertebrae in the low back (lumbar vertebrae). In addition, in the mid-buttock, beneath the fifth lumbar vertebra, is the sacrum, followed by the tailbone (coccyx).The bony spine is designed so that vertebrae "stacked" together can provide a movable support structure while also protecting the spinal cord (nervous tissue that extends down the spinal column from the brain) from injury. Each vertebra has a spinous process, which is a bony prominence behind the spinal cord that shields the cord's nerve tissue. The vertebrae also have a strong bony "body" in front of the spinal cord to provide a platform suitable for weight-bearing.The discs are pads that serve as "cushions" between the vertebral bodies that serve to minimize the impact of movement on the spinal column. Each disc is designed like a jelly donut with a central softer component (nucleus pulposus). Ligaments are strong fibrous soft tissues that firmly attach bones to bones. Ligaments attach each of the vertebrae and surround each of the discs. When ligaments are injured as the disc degenerates, localized pain in the area affected can result.

How do health care professionals diagnose a herniated disc?

The doctor will suspect a herniated disc when symptoms described above are present. The neurologic examination can reveal abnormal reflexes. Often pain can be elicited when the straight leg is raised when lying or sitting. This is referred to as a "positive straight leg raising test." There can be abnormal sensation in the foot or leg.A variety of blood tests are frequently done to determine if there are signs of inflammation or infection.Plain film X-rays can indicate "wear and tear" (degeneration) of the spine. They do not, however, demonstrate the status of discs. In order to determine whether or not a disc is herniated, an MRI scan or CT scan is performed for diagnosis. Sometimes a CT myelogram is used to further define the structures affected by a herniated disc. A CT myelogram is a CT that is performed after contrast dye is injected into the spinal canal. This allows for better visualization of the discs in certain cases. An electromyogram (EMG) can be used to document precisely which nerves are being irritated by a disc herniation.

Is it possible to prevent a herniated disc?

A herniated disc can only be prevented by avoiding injury to the spine.

What are home remedies for a herniated disc?

Home remedies for disc herniation can be very effective in relieving the pain. These include over-the-counter nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen (Advil, Motrin) and naproxen sodium (Aleve), as well as the application of heat and ice. Alternating heat and ice is very effective for pain relief for many people. Activity modification is also important, which includes avoidance of activities that aggravate pain and may worsen the nerve impingement. Bed rest and complete inactivity are unnecessary; they hinder recovery and are not advised.

What are risk factors for a herniated disc?

Risk factors for a herniated disc include degeneration of the spine and heavy lifting or bending of the spine.

What are symptoms of a herniated disc?

The symptoms of a herniated disc depend on the exact level of the spine where the disc herniation occurs and whether or not nerve tissue is being irritated. A disc herniation may not cause any symptoms. However, disc herniation can cause local pain at the level of the spine affected.If the disc herniation is large enough, the disc tissue can press on the adjacent spinal nerves that exit the spine at the level of the disc herniation. This can cause shooting pain in the distribution of that nerve and usually occurs on one side of the body and is referred to as sciatica. For example, a disc herniation at the level between the fourth and fifth lumbar vertebrae of the low back can cause a shooting pain down the buttock into the back of the thigh and down the leg. Sometimes this is associated with numbness, weakness, and tingling in the leg. The pain often is worsened upon standing and decreases with lying down. This is often referred to as a "pinched nerve."If the disc herniation occurs in the cervical spine, the pain may shoot down one arm and cause a stiff neck or muscle spasm in the neck.If the disc herniation is extremely large, it can press on spinal nerves on both sides of the body. This can result in severe pain down one or both lower extremities. There can be marked muscle weakness of the lower extremities and even incontinence of bowel and bladder. This complication is medically referred to as cauda equina syndrome.

What exercises and stretches can be done for a herniated disc?

Exercising is not advised for new symptoms of a herniated disc. On the other hand, building and maintaining strength in the back muscles and abdominal muscles is very important to prevent and treat chronic back problems. Exercises such as walking, physical therapy, and yoga have been proven to be very beneficial for those with chronic back pain.Simple stretching can be very beneficial for symptoms of a herniated disc. Stretching should be started slowly and carefully. Stretching generally involves stretching the back in a backward bending position, called extension.

What is a herniated disc? What causes a herniated disc?

As described above, each disc of the spine is designed much like a jelly donut. As the disc degenerates from age or injury, the softer central portion can rupture (herniate) through the surrounding outer ring (annulus fibrosus). This abnormal rupture of the central portion of the disc is referred to as a disc herniation. This is commonly referred to as a "slipped disc."The most common location for a herniated disc to occur is in the disc at the level between the fourth and fifth lumber vertebrae in the low back. This area is constantly absorbing the impact of bearing the weight of the upper body. This is especially important when we are standing or sitting. The lower back is also critically involved in our body's movements throughout the day, as we twist the torso in rotating side to side and as we hinge the back in flexion and extension while bending or lifting.

What is the prognosis (outlook) for a herniated disc?

The outlook for herniated disc depends on the severity and accompanying symptoms. While it is often possible to have full recovery with conservative treatment measures, sometimes surgical intervention is necessary because of persistent symptoms.

What is the treatment for a herniated disc?

Occasionally, disc herniation is incidentally detected when a test such as an MRI is performed for other reasons. If no symptoms are present, no particular treatment is necessary.Depending on the severity of symptoms, treatments for a herniated disc include physical therapy, muscle-relaxant medications, pain medications, anti-inflammation medications, local injection of cortisone (epidural injections), and surgical operations. In any case, all people with a disc herniation should rest and avoid reinjuring the disc. Sometimes, even people with relatively severe pain early on can respond to conservative measures, including physical therapy with an exercise regimen, epidural cortisone injection, and/or oral cortisone medication (such as methylprednisolone or prednisone), without the need for surgical intervention.There are now a variety of surgical approaches to treat disc herniation. Each type of operation is customized to the individual situation and depends a great deal on the condition of the spine around the disc affected. Surgical options include microdiscectomy using small surgical instruments and open surgical repair (either from a posterior or anterior approach). Urgent operation can be necessary when cauda equina syndrome is present (reviewed above).

What kind of health care professionals treat herniated discs?

Many different health care providers treat herniated discs. Usually patients will see their primary care provider initially, who may be a general practitioner or specialist in internal medicine or family practice. Other physicians who frequently see patients with herniated discs include emergency-medicine physicians, pain-management specialists, orthopedists, neurosurgeons, rheumatologists, and neurologists.
