Abstract
A bone distractor for distracting bone on opposite sides of an osteotomy of the bone. Included are a first affixation member for affixation to the bone on one side of the osteotomy and a second affixation member for affixation to the bone on another side of the osteotomy. A distraction element includes a screw having a rotatable member engaging the first and second affixation members for distracting the first and second affixation members relative to each other in response to rotation of the rotatable member. The first and second affixation members comprise resorbable material that is resorbed in the body after distraction is complete, thereby minimizing the size of the surgical wound required to remove the non-resorbable screw. Bone screws for affixing the affixation members to bone comprise a resorbable material, whereby the bone distractor can be explanted without explanting the bone screws.
