Calcaneonavicular coalition |
| Discussion |
Plain film and CT images of calcaneonavicular coalition. Notice the elongated, tubular like extension of the anterior calcaneus seen on the lateral film; this imagery has been likened to the elongated nose of an anteater. There is abnormal bony fusion of the calcaneus and navicular bones, with the presence of a bony bar extending between these two bones.
