Definition


A disk herniation is when an invertebral disk, located in the spinal column between two vertebra, slips out of position. This can lead to pressure on a nearby nerve and pain throughout the area it innervates. If medical treatment does not improve the condition and there is still severe pain, surgery can be advised. Taking the form of a laminectomy, this procedure is conducted on the spinal column, removing part of the vertebral bone, called the lamina, thus removing the herniation in order to relieve the pressure on the nerve. Another technique using microsurgery allows for a less damaging approach while hoping to achieve the same results as a laminectomy, that is to relieve the pain. In certain cases, however, despite a correctly performed surgery, the symptoms can persist.
