The authors review the clinical and roentgenographic results of 34 malunited ankle fractures in 33 patients treated at Kyushu Rosai hospital from 1978 to 1987. Proximal displacement of the tibial malleolus is left in the adduction fracture, while proximal and lateral displacement of the fibular malleolus remains in the lateral rotation fracture and in the abduction fracture. The clinical and roentgenographic results were worst in the ankle fractures with valgus displacement of the tales due to proximal displacement of the fibular malleolus. Correction of fibular shortening and of lateral rotation of the fibula is most important.
