Dysplasia of the ankle malleolus is uncommon but it may result in osteoarthritis. We developed a new treatment for dysplasia of the ankle malleolus using the Ilizarov apparatus. In the reconstruction of medial malleolus, a rectangular fragment is osteomized from the tibia and then it is moved medially and distally in the Ilizarov apparatus. When the fragment comes to the correct anatomical position, it is united to the medial cortex of the tivia with an Ilizarov olive wire. In the reconstruction of the lateral malleolus, the shortened fibula is osteomized and lengthened distally in the apparatus. Two patients had their ankle reconstructed using this technique with very satisfactory results. Although dysplasia of the ankle malleolus is often associated with leg length discrepancy and foot deformity, the simultaneous correction cannot be done with the conventional procedures reported by Gruca, Serafin and other authors. We conclude that this procedure be considered as the definitive operation because these conditions can be treated at one stage.
