Simultaneous arthrography of the talocrural and talonavicular joints in children. I. Technique.

A method is described by which simultaneous arthrography of the talocrural and talonavicular joints is performed on neonates and small infants with a high degree of success and a very low risk of complications. From films exposed in exact, standardized projections, valuable and highly reproducible information is obtained about the configuration of the talus, the shapes and mutual relationships of the joint surfaces, and any obliteration of the recesses. One disadvantage of the method is the need for general anaesthesia.
