Unilateral, volume- expanding os subcalcis. Patient history and treatment. A case report

Abstract Accessory bones of the foot are common, but the presence of accessory bones located at the plantar aspect of the calcaneus is rare. We present the case of a 72-year-old female that suffered with a volume expanding os subcalcis. Due to marked disability, the large os subcalcis was excised with a favorable outcome.
