Method and apparatus for external bone fixator

摘要

An external fixator for securing a first bone portion in a position relative to a second bone portion. The fixator includes a first clamping assembly for receiving a first bone screw connected to the first bone portion and a second clamping assembly for receiving a second bone screw connected to the second bone portion. The first and second clamping assemblies are interconnected by a main body which includes a plurality of serrated joints. Each serrated joint preferably includes first and second overlapping flanges which carry cooperating serrated surfaces adapted to selectively interlock. Each joint includes a fastener defining a pivot axis, the fasteners being operative to mechanically separate the cooperating serrated surfaces upon rotation in a first direction.
