APPARATUS AND METHODS FOR INSERTING AN IMPLANT

摘要

A system and method for inserting an implant into a cavity is disclosed, which may include advancing an implant insertion instrument toward a pair of adjacent bodies, the implant insertion instrument having two opposed ramps, wherein each ramp has a distal tip and wherein the longitudinal axes of the opposed ramps are separated by an initial angle, inserting the distal tips of the opposed ramps between the adjacent bodies, thereby creating an initial interbody cavity between the adjacent bodies,- expanding the interbody cavity while maintaining the initial angle between the longitudinal axes of the opposed ramps,- placing the implant in a final location between the adjacent bodies,- transferring a compressive force urging the adjacent bodies together from the opposed ramps to the implant; and extracting the implant insertion instrument from the interbody cavity.
