Irreducible fracture of the calcaneus in a child.

Displaced fractures of the calcaneus are rare in children, and most do not require open reduction as a treatment modality. The case of a 4-year 8-month-old boy who sustained a fracture of the anterior process of the calcaneus requiring open reduction is presented; no similar fracture in childhood has been previously reported. Treatment guidelines for calcaneal fractures in children are reviewed.
