Abstract

The application is directed to implants that are adjustable between collapsed and expanded orientations. The collapsed orientation includes a smaller height to facilitate insertion into the patient. The expanded orientation includes a larger height for spacing and/or supporting the vertebral members. The implants generally include three or more separate sections that are nested together in the collapsed orientation. The sections move outward away from each other in the expanded orientation. An expansion means may be operatively connected to one or more of the sections to move the implants between the orientations. Methods of use are also included for moving the implants between the collapsed and expanded orientations.
