Aim: To describe our experience of modified technique of translational step cut osteotomy for the correction of cubitus varus deformity in children and to access the functional outcome at 6th month of follow-up.
Methods: We enrolled 27 children of either gender or side between ages from 5 to 12 years having cubitus varus deformity at our institute. After clinical and radiological workup, all children underwent correction of the deformity using modified technique of translational step cut osteotomy.
Results: Mean age of children was 8.41±2.15 years and duration from initial injury to presentation was 14.2 ± 5.71 months having male predominance. The mechanism involved were fall (55.6%), followed by road traffic accident (22.2%) and playground area (22.2%). Most children had right side deformity (66.7%). 51.9% children have initial treatment from bonesetter making cosmesis and functional reasons as main factor for parents to seek medical advice. Radiological union was achieved in the mean duration of 5.00 ± .62 weeks. The mean pre-operative humero-ulnar angle of the involved side was 199±10.58o and post-operative angle at the end of 6th month of the involved side was 170.62±4.12o.
Conclusion: Step-cut translational osteotomy humerus is very good procedure for correction of cubitus varus deformity with negligible complications and excellent to good outcomes according to Flynn’s criteria.
