Intraoperative C-arm views showing the various steps of the procedure: A A Hohmann retractor was used through the osteotomy site as a lever to maintain the correction and lateral translation of the distal segment. B Acute multiplanar correction was then carried out which included derotation, angulation, translation. C Two converging 2 mm wires were used for the preliminary fixation of the osteotomy. D Assessment of the correction by the mechanical access highlighted by the shadow of the electrocautery cable passes through the centre of the knee. E, F Anteroposterior and lateral views during application of the frame
