Lumbar Disc Herniation

A herniated disk refers to a problem with one of the rubbery cushions (disks) that sit between the individual bones (vertebrae) that stack to make your spine.A spinal disk has a soft, jellylike center (nucleus) encased in a tougher, rubbery exterior (annulus). Sometimes called a slipped disk or a ruptured disk, a herniated disk occurs when some of the nucleus pushes out through a tear in the annulus.A herniated disk, which can occur in any part of the spine, can irritate a nearby nerve. Depending on where the herniated disk is, it can result in pain, numbness or weakness in an arm or leg.Many people have no symptoms from a herniated disk. Surgery is usually not necessary to relieve the problem. Causes Disk herniation is most often the result of a gradual, aging-related wear and tear called disk degeneration. As you age, your disks become less flexible and more prone to tearing or rupturing with even a minor strain or twist.Most people can't pinpoint the cause of their herniated disk. Sometimes, using your back muscles instead of your leg and thigh muscles to lift heavy objects can lead to a herniated disk, as can twisting and turning while lifting. Rarely, a traumatic event such as a fall or a blow to the back is the cause.
