A device and method for performing distraction osteogenesis. The distraction osteogenesis device, in accordance with the present invention, is modular in construction, and has at least two bioabsorbable footplates having screw or rivet holes therein and an extendable member therebetween. The extendable member is used to change the distance between the footplates. When performing the distraction osteogenesis procedure, the footplates are affixed to the bone on either side of an osteotomy/fracture by means of bioabsorbable screws or rivet bone fasteners. The footplates are connected to one another by the extendable member which spans the osteotomy site and stabilizes the bone segments comprising the osteotomy/fracture. Following implantation of the distractor, the extendable member is periodically elongated to incrementally separate the segments of the bone affixed to the respective footplates. Osteogenesis within the osteotomy site is sustained as the juxtaposed ends of the bone segments incrementally separate. When the bone attains a desired length and/or curvature, further elongation of the distractor is discontinued and the newly formed bone is permitted to harden. The extendable member is disconnected from the footplates and surgically explanted. The bioabsorbable footplates and the bioabsorbable screws or rivets affixing the footplates to the bone are not disturbed during explantation of the extendable member and are absorbed by the body over time. The bioabsorbable footplates may be adapted for use with a variety of extendable members.
