An accessory navicular is an extra piece of bone material that is located just above the arch on the inside of the foot.
It's usually encased in the posterior tibial tendon, which attaches the inside arch of the foot to the calf muscle. Accessory Navicular is a condition we commonly see in our pediatric patients.
Most people do not have an accessory navicular. People who do have one are born with the condition. And while many go their whole lives without realizing they have the extra bone, in some it causes pain or other problems.
