What is Accessory Navicular Bone?
An accessory navicular bone is an accessory bone of the foot that occasionally develops inside of the foot. This bone is usually asymptomatic and may be present in approximately 2-14% of the general population. When it does become symptomatic, surgery may be necessary to remove the bone.
Symptoms of an accessory navicular bone may include pain and swelling to inside part of the foot at the level of insertion of posterior tibial tendon.
