We treated two cases of tibia vara deformity with metaphyseal dysplasia using hemicallotasis technique. One was a 16-year-old boy with 12 degrees of bilateral tibia vara. Another was a 17-year-old boy with 17 degrees of tibia vara in the right side, and 18 degrees of tibia vara in the left side. After osteotomy, hemicortical elongation was gradually performed until the aimed angular correction was gained. Height was increased by 1.5cm. There were no problems in both cases and we concluded that the Orthofix technique is useful for the treatment of tibia vara deformity and shortening.
