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
