From: Low-intensity pulsed ultrasound enhances callus consolidation in distraction osteogenesis of the tibia by the technique of lengthening over the nail procedure

Fig. 1

Sequential radiographic images of the left tibia in a 22-year-old female patient who received low-intensity pulsed ultrasound (LIPUS) after 7.3 cm of tibial lengthening. At the end of the distraction phase, the anteroposterior (AP) (a) and lateral (b) images show a callus with a cylindrical shape and intermediate density. At the time of external fixator removal, the AP (c) and lateral (d) images show progression of callus consolidation with a cylindrical shape and normal density. The external fixation index of the patient was 29.6 days/cm. At 9 months postoperation, the AP (e) and lateral (f) images show full corticalization of the regenerated callus
