Abstract
An implant includes: an inner rod having an outer surface; an outer rod in telescopic engagement with the inner rod, the outer rod having a threaded inner surface in axial slidable engagement with the outer surface of the inner rod; the inner rod and the outer rod each having an end configured for attachment to bone; a rotational actuator housed within the inner rod; and a lead screw in axial alignment with the rotational actuator and rotationally coupled thereto, the lead screw in threaded engagement with the threaded inner surface of the outer rod, whereby rotational motion of the actuator is converted into linear motion, resulting in telescopic changes in the overall axial length of the device.
