Publication number: 20050043740Abstract: Instrumentation and techniques for preparing vertebral members for insertion of an implant. Foundation instruments provide a reference relative to the vertebral members. The foundation devices guide the placement of one or more instruments that prepare the vertebral members. The instruments operatively align with the foundation instruments in a specific orientation to ensure proper placement relative to the vertebral members. Preparatory instruments may be used to further remove bone from the vertebral members. The preparatory instruments may be used prior to or after the other instruments. An insert is inserted and mounted to the vertebral members after the bone has been removed. A holder may be used for holding and placing the implant relative to the vertebral members.Type: ApplicationFiled: August 20, 2003Publication date: February 24, 2005Inventors: Regis Haid, Vincent Traynelis, Thomas Zdeblick, Bradley Coates, Greg Marik, Craig Squires, Courtney Williams, Linda Holmes
