Spinal Disc Herniation

Slipped Disc, Herniated Nucleus Pulposus

Spinal disc herniation is a bulging intervertebral disc. The bulge can press on a nerve, causing pain in an arm or leg. A spinal disc herniation does not always cause pain in the back. But if there is back pain, it is often severe and feels stabbing or sharp. Spinal disc herniation usually occurs in the lower back and less frequently in the neck.


Cause

The intervertebral disc has an elastic ring and a soft interior. The vertical posture puts pressure on the elastic ring. Due to weakening, the soft inside can start bulging and pinch a nerve that runs nearby.

Wear of the intervertebral disc is the main cause of spinal disc herniation. This is the cause in about half of the people over fifty years. Usually, however, a spinal disc herniation causes no symptoms. The condition is part of the aging process. It’s often unclear what is causing symptoms of a herniated disc. Heavy work with a lot of lifting can cause back pain, but it doesn’t cause spinal disc herniation.


Symptoms

The main symptom is low back pain, radiating to a leg or neck pain, radiating to an arm. The pain arises in a short time, often for no apparent reason, sometimes suddenly, for example when lifting. The radiating leg pain is worse than the back pain. There is often also tingling or numbness in a part of the leg or in the foot. The pain increases with coughing and pressing. Lying down usually relieves the pain.


Diagnosis

The diagnosis of spinal disc herniation is usually already clear on the basis of the symptoms only. With specific tests of the physical examination, nerve stimulation can be determined. In order to determine which nerve is pinched, the route of the radiating pain is important. Furthermore, the doctor examines muscle strength, reflexes and skin sensation. A spinal disc herniation can be seen on an MRI scan.


Treatment

The pain diminishes when the pressure on the nerve reduces. The bulging intervertebral disc will have to shrink, which almost always happens spontaneously. In the first weeks, the back should be loaded as little as possible, but bed rest is not necessary. Painkillers help to overcome this period. In about eighty percent of people, recovery occurs in a period of two to three months.

In case of severe pain, the general practitioner may prescribe painkillers. Sometimes, the doctor may also provide opioids, which are painkillers derived from opium. These drugs are intended to eliminate the worst pain, but they don’t cure the spinal disc herniation.

Surgery is to be considered in case of permanent pain. In some specific situations, surgery is necessary in an earlier stage. In general, the worse the symptoms, the greater the chance that surgery will lead to improvement. During the operation, which is carried out under general anesthesia, the damaged disc is removed. The pinched nerve, that causes the problems, would then have adequate space. After the operation, a scar arises at the site of the removed intervertebral disc. So it’s not that the vertebrae will directly be on top of each other.


Prognosis

The course of a spinal disc herniation varies greatly. In the majority of cases, it’s a condition that heals spontaneously in a few months, without residual symptoms, or sometimes with the remaining of a numb spot or a slight loss of strength. In some cases, surgical intervention is required.

Research shows that eighty to ninety percent of the patients is satisfied with the final result after spinal disc herniation surgery. About five percent of patients operated gets a spinal disc herniation again at the same place. However, this can also be surgically treated with a good result.
