Accessory Navicular Syndrome

What Is Accessory Navicular Syndrome?

Accessory Navicular Syndrome (also known as, "os navicularum" or "os tibiale externum") is extra cartilage or bone located above the arch of the foot, potentially leading to pain and discomfort. This condition is congenital, which means it is present at birth. Although Accessory Navicular is not part of the typical bone structure, it still often goes unnoticed. Symptoms will often manifest during adolescence while cartilage and bones are still developing.


Symptoms of Accessory Navicular Syndrome

The accessory navicular ("extra bone") will be a visible protrusion from the foot and will typically be accompanied by redness and swelling. You may also notice a dull, throbbing pain in the arch of the foot. This pain will worsen with increased physical activity.



Foot Conditions related to Accessory Navicular Syndrome

Accessory Navicular Syndrome is closely related to other foot conditions such as,"bunions", "os peroneum", "tarsal coalition" and "plantar fibroma" which can produce similar feelings of foot pain and can feel like a small painful bump under the foot.


How To Treat Accessory Navicular Syndrome

Non-Surgical Treatment

For those looking for relief from the symptoms of Accessory Navicular, we recommend a softer shoe that reduce the impact on the foot. Wider fits and adjustable closures can also help alleviate some of the pressure on the accessory navicular. Reducing physical activity can also help relieve some of the pain associated with this foot condition.

Surgical Treatment

If pain is overwhelming, your doctor may recommend medical procedures that remove this extra bone. The "Kidner Procedure" is the most common surgical option for accessory navicular syndrome. This surgery is a simple removal of the extra bone. Recovery time is typically only 6 weeks to resume physical activity.
