Many of these techniques are more suitable for uniplanar ankle deformity. Particularly, if there are multiplane ankle deformities, the use of the six-axis deformity correction system may be successful in solving the problems which may occur during the correction. In this article, we report two cases of three plane deformities of ankle joint due to trauma sequelae, which were treated with supramalleolar osteotomy using a hexapod fixator which is called the Smart Correction Frame®.
