The "anteater nose": a direct sign of calcaneonavicular coalition on the lateral radiograph.
On the lateral foot or ankle film of patients at least 9 years old with calcaneonavicular bar (CNB), there is a tubular prolongation anteriorly of the superior calcaneus which fancifully resembles the nose of an anteater. This prolongation approaches or overlaps the midportion of the navicular. Such a configuration was present in all 30 feet reviewed with CNB, but not in 125 feet of 100 subjects, in their second decade, without CNB.
