Abstract

Devices and methods for immobilizing adjacent vertebrae are disclosed including the utilization of one or more implants inserted between adjacent vertebrae and having protrusions thereon for substantially fixedly securing with the vertebrae. In one form, an implant may be inserted in a first orientation and then rotated to a second orientation having a larger profile. A second implant may also be inserted in the same vertebral space in the same manner. A trial spacer may be used to determine the proper implant size. In another form, an implant may be inserted already in the fusion orientation. The implants and trial spacer, as well as a spreader and/or a scraper for preparing the intervertebral space, may be inserted in the vertebral space with the same insertion tool. The inserter tool may include a threaded member for attachment with the implants or other devices.
