A Typical Bifid Os Calcis: A Case Report

The bifid os calcis may be defined as anomalous ossification characterized by a calcaneus with two parts. Synonymous terms are calcaneus bipartitus or duplicate calcaneus. The calcaneus is separated by a cleft into a small anterior part and large posterior part. The anomaly usually is bilateral.1,4,6 We describe an isolated case of a bifid calcaneus with a small posteromedial part and a large anterior part.
