Accessory navicular bone

What causes accessory navicular bone?

An accessory navicular bone is typically considered to be a developmental abnormality present from birth (congenital). Research involving large studies of families of individuals with accessory navicular bone suggests a genetic influence with possible autosomal dominant inheritance. The exact cause of accessory navicular bone is unknown; however, it may be related to an incomplete joining (fusion) of bones and connective tissue during development and/or an abnormal separation of affected bones and connective tissue.

How might accessory navicular bone be treated?

If the accessory navicular bone is causing symptoms, activities may be restricted and a softer shoe may be recommended until the symptoms go away. If the symptoms persist, a specially and carefully made shoe support may be tried. For people with accessory navicular bone who experience severe symptoms, surgery may be considered to remove the bony growth. Other treatments may include medications such as nonsteroidal anti- inflammatories (NSAIDs), immobilizing the area with a cast or boot, and physical therapy.
