In congenital convex pes planovalgus, the navicular is typically positioned:

• A. Ventral to the talus
• B. Medial to the talus
• C. Dorsal to the talus
• D. Distal to the talus

Answer: (C)

In congenital convex pes planovalgus, the navicular bone is typically positioned dorsal to the talus. This condition involves a flatfoot deformity characterized by a pronounced arch under the load-bearing conditions, and it often results from normal development occurring in utero. The dorsal positioning of the navicular in this context is significant because it indicates a disruption in the normal mechanical alignment of the foot's structure, which affects weight distribution and stability. The abnormal positioning can lead to not only deformities but also functional issues as the foot may lack the necessary support from the arch, ultimately leading to compensatory mechanisms in gait and weight distribution. Understanding the typical positioning of the navicular, particularly in relation to the talus, is crucial for clinical assessments and treatment planning in cases of congenital foot deformities. Recognizing that in this condition the navicular shifts dorsally rather than maintaining a more medial or ventral position allows practitioners to better evaluate the overall alignment and function of the foot in these patients.
