Claim Text:
1. A method of vertebral stabilization, comprising the steps of: placing a generally flattened four sided disc between two human vertebrae, said flattened disc comprising a generally flat second side, and a first side with 4 tapering sides forming four disc edges, and with said second side being beveled along said edges, with a first and second opposing edges having straight slightly curved edges generally opposite each other, with the third and fourth edges each having a pair of pointed lobes with a notch between said lobes, with said second side having a recess for a tool, with said disc placed on edge between two vertebrae with said slightly curved edges on vertebrae inner faces and with said tool recess accessible from outside said vertebrae; inserting a tool into said tool recess; turning said tool and said flattened disc ninety degrees using said tool until said sides with said pointed lobes on said third and fourth edges contact said vertebrae faces; removing said tool from contact with said disc; and leaving said disc between said adjacent vertebrae as a spacer to prevent contact between said adjacent vertebral faces with nerves between said adjacent vertebrae.
