CT scan in a study of the normal anatomy of the hindfoot and midfoot.

The authors use CT scan to describe the anatomy of the hindfoot and midfoot. Initially the bones and related joints are examined, the latter being particularly complex and difficult to evaluate in this area with traditional radiology. Particular emphasis is placed on the description of the subtalar joint complex, to which all the bones of the hindfoot and midfoot contribute with the exception of the cuneiforms. This is followed by a description of the anatomical features of the soft tissues. The components of the five areas into which the hindfoot and midfoot may be subdivided are illustrated, with particular emphasis on the structures of the medial region which contribute to the formation of the tarsal tunnel. Starting from a description of the anatomy of this area, the main neurovascular trunks, the fascial structures, ligaments and muscles in the various sites are defined.
