Digit-Like Bony Anomaly of the Hindfoot: A Case Report.

We report the case of an asymptomatic digit-like bony anomaly located on the plantar aspect of the calcaneus, which was incidentally found on radiographs of a 50-year-old male with a tibial shaft fracture. To the best of our knowledge, this is the first description of such an anomaly in the foot. The differential diagnosis includes accessory ossicles, polydactyly, heel spur, heterotopic ossification, osteochondroma, and pelvic digits.
