An os calcaneus secundarius is an accessory ossicle of the anterior calcaneal process present in up to 5% of the population at cadaveric examination. The ossicle can be a cause of ankle pain and may mimic bifurcate ligament avulsion fracture of the anterior calcaneal process.
Differential diagnosis
- fracture of the anterior process of the calcaneus - difficult to distinguish from an os calcaneus secundarius if the suspected fracture is subacute or chronic.
- fracture of the tuberosity of the calcaneus
- calcaneus accessorius
- cuboideum secundarium
- os sustentaculi
