New internal transport distraction device for reconstructing segmental defects of the mandible.

We have developed a new internal distraction device for the transport of bone, which comprises a bridging reconstruction plate, a bracket with miniplates for fixing the transport disc, a traction mechanism, and traction wire. The entire device except for part of the traction mechanism is placed internally. Activation of the traction mechanism slides the bracket on the rail of the reconstruction plate with the traction wire, which carries the transport disc along the rail. The traction mechanism can be removed after the period of distraction, leaving only the other components during consolidation.
