A roentgenographic technique to evaluate and document hindfoot position.

ABSTRACT

The position of the posterior portion of the foot is difficult to evaluate and document on the basis of clinical examination. Conventional roentgenographic techniques also do not allow objective determination of hindfoot position. A new roentgenographic technique utilizing a double-exposure has been developed to allow accurate documentation of the position of the calcaneus relative to the ankle. Normal adult values for this technique have been determined from 60 normal feet.
