Intraoperative ultrasound for evaluation of reduction in congenital talipes equinovarus

A technique of intraoperative ultrasound for evaluation of reduction in congenital talipes equinovarus (CTEV) is reported. Ultrasound (US) scanning enables the surgeon to perform controlled reduction of both calcaneocuboid and talonavicular joint during the operation because visualization of the relation in the medial and lateral column of the foot is as precise as that obtained with radiographs. The relation between talus and calcaneus in the horizontal plane cannot be visualized. Examination is quick and simple but is more easily performed if the shape of the foot is near-normal; i.e., the foot has been well prepared for operation by nonoperative treatment.
