A Guide to the Accessory Navicular Bone
What is an accessory navicular bone?
The accessory navicular bone (ANB) is an additional bone or piece of cartilage located above the arch of the foot, adjacent to the navicular bone, a key structure in the midfoot. The ANB is a congenital anomaly, present in approximately 2–25% of the population, and can vary in size, shape, and exact position, leading to different classifications. While it is not essential for normal foot function, the ANB can sometimes become irritated over time, resulting in accessory navicular syndrome (ANS). This condition may cause pain, swelling, and tenderness along the inner foot, potentially making walking and physical activity difficult.
For more information on the ANB, including common disorders, treatment options, or personal experiences with accessory navicular syndrome, explore the other sections.
