[Calcanear fractures. Advantages of horizontal tomography in exact diagnosis of the type of injuries (author's transl)].

The usual radiographic projections do not enable to do a complete diagnosis of the pattern of the calcanear fractures. Horizontal tomograms, performed since 1975 by the authors with a complex movement tomographe show the superior surface of the calcaneus. Compared with the sagittal and frontal tomograms, they are absolutely necessary to know the shape of the fractured calcaneus and to precise the anatomical basis of its treatment.
