A multi-plane bone distraction system including a saw guide, a drill guide, a rigid plate and a distraction assembly for use as a distraction device in cutting and lengthening the bone or as a compression device in cutting and shortening the bone in conjunction with repositioning the other end of the bone in three planes relative to the one end of the bone.

Multi-plane bone distraction system

The bone saw guide of this invention allows precise perpendicular or angular cutting of a bone with a conventional bone saw. An inverted U-shaped blade guide portion positions the blade and an upstanding saw guide portion guides the neck of the saw. A plate connects the two portions. The invention allows a bone segment to be removed and the cut ends to be compressed together to shorten the bone.

Precision bone cutting guide

A bone compression and distraction device for compressing and distracting the ends of a bone and affixing a splint plate thereacross. The device comprises a pair of blocks interconnected by an adjustment assembly. The blocks are each seated on the ends of the splint plate and connected to the respective ends of the bone by a long bone screw positioned through a transverse hole in the block and through aligned holes in the splint plate. One of the holes in the splint plate is slotted to allow the compression or distraction of the bone ends whereupon short bone screws are positioned through other holes in the splint plate into the bone ends allowing the blocks to be removed and its screws replaced by short bone screws positioned through the same holes in the plate and into the bone ends.
