Abstract
Abstract An improved prosthetic implant for forming a rigid structure between adjoining vertebrae in a spinal column. The prosthetic implant includes a cage having a top, bottom, front end, back end, first side and second side walls. The first side wall has an arcuate surface. The top and bottom wall include one or more ridges to engage a surface of an adjacent vertebrae. The top and bottom wall also include an opening to receive packing material such as medicine, human tissue and the like. The top and bottom walls also incline simultaneously in two directions.
