1. A device for adjusting the relative positions of bone segments, comprising:
a body having a length;
a pair of rods, each of said rods rotatably supported by said body, a first of said rods including a first externally threaded rod portion longitudinally extending about a first axis, a second of said rods including a second externally threaded rod portion longitudinally extending about a second axis, said second axis being spaced apart from said first axis;
a movable carriage threadably coupled to the threaded portion of one of said rods, said carriage being adapted and configured to attach to an implantable device that is couplable to one of the bone segments; and
a platform affixed to said body, said platform being adapted and configured to attach to another implantable device that is couplable to one of the bone segments,
wherein threads of the first externally threaded rod portion are laterally spaced apart from threads of the second externally threaded rod portion, wherein rotation of the one said rod moves said carriage along the threaded portion of the one said rod, and
wherein said movable carriage includes a hole having an inner diameter greater than the major diameter of the threaded portion of the one said rod, said other rod passing through the hole.
