Plague Inc. has been downloaded over 10 million times worldwide and over 200 million games have been played to date. As an intelligent and sophisticated strategy game, I think Plague Inc. appeals to people looking for something more meaningful and substantial than the majority of mobile games.
Anterior Cervical Discectomy & Fusion (ACDF) Overview. Anterior cervical discectomy and fusion (ACDF) is a surgery to remove a herniated or degenerative disc in the neck. An incision is made in the throat area to reach the front of the spine. The disc is removed and a graft is inserted to fuse together the bones above and below the disc.
But in some cases, the nucleus pushes completely through the annulus and squeezes out of the disc. This is called a disc herniation or protrusion. Herniation and protrusion are two words for the same thing. If a piece of the disc breaks off, it's called a sequestered fragment. Surgery is almost always needed for sequestration. The loose piece can enter the spinal canal and put pressure on the spinal cord or spinal nerve roots causing serious problems.
