Accessory ossicles of the feet are common developmental variants with almost 40 having been described. Some of the more common include ^1-4:

os peroneum
os subfibulare
os subtibiale
os tibiale externum (accessory navicular)
os trigonum
os calcaneus secundaris
os calcanei accessorium ⁶
os intermetatarseum
pars peronea metatarsalis primi (pars peronea metatarsalia)
os supratalare
bipartite hallux sesamoid
os supranaviculare
os infranaviculare (cuneonavicular ossicle) ⁵
os intercuneiforme
os vesalianum pedis
os sustentaculi
os subcalcis
os cuboideum secundarium
os talotibiale
os paracuneiforme
os aponeurosis plantaris
os cuneometatarsale plantare
os talus secundarius
os cuneometatarsale I tibiale
os cuneo–I metatarsale-II dorsale

Knowledge of their presence is helpful so that they are not misdiagnosed as fractures.
