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 ...
Definition A brain herniation is when brain tissue, cerebrospinal fluid, and blood vessels are moved or pressed away from their usual position inside the skull. Alternative Names Herniation syndrome; Transtentorial herniation; Uncal herniation; Subfalcine herniation; Tonsillar herniation; Herniation - brain Causes, incidence, and risk factors Brain herniation occurs when something inside the skull produces pressure that moves brain tissues. This is most often the result of brain swelling from a head injury, stroke , or brain tumor. Brain herniation is the most common side effect of tumors in the brain, including: Metastatic brain tumor Primary brain tumor Herniation of the brain can also be caused by other factors that lead to increased pressure inside the skull, including: Abscess Hemorrhage Hydrocephalus Strokes that cause brain swelling Brain herniation can occur: Between areas inside the skull, such as those separated by a rigid membrane like the tentorium or falx Through a natural opening at the ...
