Os supranaviculare
Dr Mohammad Taghi Niknejad and Dr M Venkatesh et al.
The os supranaviculare is an accessory ossicle 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.
