Correction of a severe poliomyelitic equinocavovarus foot using an adjustable external fixation frame

One-stage surgical correction of severe equinocavovarus deformity can result in complications ranging from skin necrosis to tibial nerve palsy. Fewer complications have been reported when severe deformities were treated by gradual correction using external frames such as the Ilizarov external fixator or the Taylor Spatial Frame™. We describe a case of a 64-year-old female patient with severe poliomyelitic equinocavovarus whose deformity required her to ambulate using the dorsum of her right foot as a weightbearing surface. We treated the deformity with gradual correction using a Taylor Spatial Frame™, followed by ankle arthrodesis. At the most recent postoperative evaluation, 20 months after the initial surgery, the patient was pain free and ambulating on the sole of her right foot.
