Fractures of the calcaneus. Part I: Anatomy, injury mechanism, and classification.

Calcaneal fractures have been treated by closed methods since the time of Hippocrates. The understanding of the anatomy, injury mechanism, and classification of these fractures has advanced since surgical treatment was introduced in 1850. Despite 145 years of different treatment techniques, no consensus has been reached. Investigation into the injury patterns, anatomy, and outcomes has lead to the advances reviewed in this article.
