Roentgenographic examination of the subtalar joint

In fractures of the calcaneus, the traditional roentgenographic technique cannot provide the necessary information for surgically restoring the subtalar joint and correctly judging the prognosis. The author recommends the oblique view roentgenographic technique which provides essentially more information than Boehler's axial roentgenogram, and can technically be taken more easily. Data obtained by using the oblique view roentgenographic technique facilitate the diagnosis of fractures of the calcaneus and allow the assessment of the degree of dislocation, and of the displacement of the articular surface, i. e. the correct judgement of the surgical intervention.
