Calcaneal Avulsion Fractures: An Often Forgotten Diagnosis.

Abstract

The calcaneus is the primary weight bearing bone in the heel, and its many surface contours render it a relatively difficult bone to visualize in its entirety. The stabilizing ligaments that hold the calcaneus in place occupy very specific locations, and the Achilles tendon enthesis is in a relatively constant location; therefore, avulsion fractures occur in reproducible locations. The mechanisms of injuries include overuse and neuropathic conditions, although most cases are related to trauma.
