Lateral closing wedge osteotomy is a commonly described procedure for correcting cosmetically unacceptable post-traumatic cubitus varus deformity in children. We report a case of 12-year-old boy who underwent step cut osteotomy for cubitus varus deformity. Preoperative measurements of varus deformity followed by planning of osteotomy using a template was done. Intraoperatively the preplanned cuts were made using a posterior approach and then fixation was done using k wire. Patient recovered completely with correction of deformity. Step cut osteotomy has key advantages over traditional closing wedge osteotomy and hence can be used as an alternative surgical technique.
