Abstract:
An intervertebral implant includes a body having an upper surface, a lower surface and a transverse fastener hole. The body includes a dynamic fixation mechanism for seating a fastener in the fastener hole and translating the fastener relative to the implant to accommodate subsidence of the implant. In one embodiment, an implant includes a transverse slot with an elongated seat for translating a seated fastener relative to the implant. In another embodiment, an implant includes a displaceable sliding member for translating a fastener relative to the implant.
