Computed tomography of the calcaneus: normal anatomy

The normal sectional anatomy of the calcaneus was studied as the background for interpretation of computed tomography (CT) of fractures. Multiplanar CT examination of the normal calcaneus was obtained, and sections were matched with a simplified anatomic model. Sectional anatomy in the four most important planes is described. This facilitates three-dimensional understanding of the calcaneus from sections and interpretation of CT sections obtained in any atypical plane.
