ABSTRACT:
A kit of assemblable components for implantation into the bone of a mammal for use in distraction osteogenesis. The kit comprises a fixture, a footing and a distracter, the fixture including a longitudinally extending body portion with a proximal end and a distal end, the body portion having an exterior surface adapted for contact and integration with bone tissue, the body portion having a generally longitudinally extending bore extending from a proximal opening adjacent the proximal end to a distal opening adjacent the distal end. The footing includes a proximal surface and a distal surface. The distracter comprises a generally rod-shaped body including a distal end and a proximal end, and the proximal end of the distracter is adapted to bear against the footing. There are first and second engaging means on the fixture and the distracter respectively for adjustably locating the fixture relative to the distracter.
