Os tibiale externum and os supranaviculare

Case contributed by Dr Raul Medina


Ankle pain

Patient Data

Age: 73
Gender: Male

Large superimposed naviculare accessory and a small os supranaviculare up and between talus and naviculare are clearly depicted. 

Case Discussion

The tibiale externum was mistakenly considered a fracture. As with any accessory bone, knowing their existence is priority. Exclude a fracture is easy, whenever the corticated edges of a pseudofracture radiolucent line, can be defined.
