Radiological examination of the ankles of spina bifida children with flail lower limbs and valgus flat foot deformity has revealed a high incidence of abnormal valgus tilt of the ankle-joint. A study of ankle X-rays of spina bifida children before and after extra-articular subtalar fusion in which the bone graft is removed from the ipsilateral tibia has shown that the valgus tilt of the mortice may increase after this procedure.
