An os supranaviculare is an accessory ossicle of the foot located at the proximal dorsal aspect of the navicular bone or talonavicular joint. It is also known as Piries bone, talonavicular dorsale, or (dorsal) talonavicular ossicle and is present in ~1% of the population.
Differential diagnosis
An os supratalare is also anatomically seen in close proximity, sitting above the talar beak, but not at the superior margin of the navicular bone.
Additionally, It is important to differentiate an os supranaviculare from the dorsal avulsion fracture of the navicular bone.
