ABSTRACT
PURPOSE: evaluate the radiologic and clinical results of modified step-cut osteotomy for correction of cubitus varus deformity in children. MATERIALS AND METHODS: We analysed 16 children who had varus deformity preoperatively and received modified step-cut osteotomy. The results were evaluated by final follow-up radiographs and clinical results, which were humeral-elbow-wrist angle, lateral prominence, range of motion and complications. RESULTS: The average preoperative humeral-elbow-wrist (HEW) angle was -15.8degrees and average last follow-up HEW angle was +6.7degrees Lateral prominence under 5 mm occurred in 3 cases and one children showed limited motion and transient ulna neuropathy. CONCLUSION: The results demonstrate that modified step-cut osteotomy achieve good correction of cubitus varus without lateral bony prominence or complications.
