What is posterior herniation?
Posterior herniation is when a disc in the spine becomes damaged and bulges outward from the spinal column toward the back. Common causes are work related injury and age.
A broad herniation means that at least 25% of the disc is affected. A central herniation means that the herniation is toward the spinal column. A broad central herniation of the disc with impingement on the thecal sac is a herniation in which a large portion of the disc is protruding toward the spinal column and is pressing against the membrane which surrounds the spinal cord.
It is descriptive term for the degenerative spine on CT or MRI. Central disk herniation means a central and posterior protrusion of disk material. Posterolateral disc protrusion indicates herniation of disk along the posterolateral margin of the disk to the spinal canal. Disc spur complex denotes a combined degenerative process with which the protruded disk is accompanied with adjacent bone change with spurring.
For a bit of background, a spinal disc herniation is a condition in which the vertebrae/discs bulge or distend beyond its usual anatomical position. Many people refer to a spinal herniation as a "slipped disc", while in fact this is not true. A spinal disc cannot simply 'slip' out of position unless very severe trauma is involved. The term 'posterior' is a medical term meaning 'backwards'. In this context, it means the spinal disc has…
