Biomechanical Considerations in the Hindfoot

Abstract

An examination of normal hindfoot function puts into perspective the advantages of anatomic internal fixation for both talar and calcaneal fractures. Almost all talar fractures involve the subtalar or the talocalcaneal joints directly or indirectly. Intra-articular calcaneal fractures, which account for at least 70% of all calcaneal fractures, are commonly treated by internal fixation and, by definition, always involve the subtalar joint.
