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 screw means has 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. An extension member is removably connectable to the rotatable member of the screw means for imparting torque to the screw means when connected thereto and rotated. The extension member can be flexible to permit elastic bending while imparting torque.
