A case of a 4.5-year-old male who had undergone a previous excision of CPT when he was 3 years old. A AP and lateral X-rays showing recurrence of sclerosis and obliteration of medulla, and an impending fracture was noted. B AP and lateral X-rays showing refracture of the tibia and dysplastic fibula. C Immediate postoperative AP X-ray showing complete CPT excision, proximal corticotomy, intramedullary alignment using transcalcaneal wire, and near-total occlusion of the pseudarthrosis site by acute intraoperative shortening. D Lateral X-ray taken 8 weeks postoperatively, showing progression of union at the docking site and distraction at the regenerate. E Pre-removal AP and lateral X-rays showing complete union at the docking site and full consolidation of the regenerate. Note that the transcalcaneal wire was removed at an earlier stage. F AP and lateral X-rays taken 1 month after the removal of the frame, which show solid union without any sign of recurrence
