(a) Anteroposterior (on the right) and lateral radiographic (on the left) views of left tibia (case 4) showing very discrete bone regenerate after 6 weeks of distraction at a rate of 0.25 mm × 2 times/day. (b) Anteroposterior (on the right) and lateral radiographic (on the left) views of left tibia (case 4) after 7 weeks of the accordion technique showing significantly improved osteoformation.
