EXPANDABLE FIXATION ASSEMBLIES

摘要

Expandable fixation assemblies, expandable cranial fixation assemblies, and expandable intervertebral implant assemblies are provided for securing structures to bone and for securing bones and/or bone segments with respect to each other. An expansion member (26) can be moved through at least a portion of an expandable fixation body (24), thereby causing expansion of the expandable fixation body, such that bone engagement features of the expandable fixation body engage surrounding structure, such as bone.
