Disc herniation sounds scary, but what is it really? Remember from Spine Anatomy 101 that the spinal disc is a squishy thing that sits in between the vertebral bodies—the bones that make-up the spine. Normally, the disc has a certain shape, a contour that slowly begins to change as the disc ages. Sometimes, the disc will bulge in a generalized fashion beyond the boundaries of the bones. Disc bulging is very common and normal as the disc gets older. When a disc herniates, a focal part of the disc is displaced beyond the vertebral body boundary. The difference between a bulge and a herniation is the amount of disc that is involved. The tricky part is that both bulges and herniations are found in people who have no pain.

A herniated (slipped) disk occurs when all or part of a spinal disk is forced through a weakened part of the disk. This places pressure on nearby nerves.

Causes, incidence, and risk factors
The bones (vertebrae) of the spinal column run down the back, connecting the skull to the pelvis. These bones protect nerves that come out of the brain and travel down your back, forming the spinal cord. Nerve roots are large nerves that branch out from the spinal cord and leave your spinal column between each vertebrae.
The spinal vertebrae are separated by disks filled with a soft, gelatinous substance. These disks cushion the spinal colum...
A recent study revealed that percutaneous disc decompression resulted in significant relief for painful herniated discs in sciatica patients for up to two years. The results of this first-of-its-kind study, conducted at the University of Athens in Greece, were presented at the Radiological Society of North America's 95th Annual Meeting earlier this month. Study Methods This was a randomized, controlled study that compared standard conservative therapy to the minimally invasive treatment known as percutaneous disc decompression. Subjects were divided into two groups, each containing 17 men and 14 women who complained of back and leg pain and were confirmed to have herniated discs and sciatica. Both groups had tried various conservative treatments in the past which were unsuccessful. The first group received six weeks of rigorous conservative therapy, which included analgesics, muscle relaxants and anti-inflammatory medications. The second group ...
