Accessory navicular bone is the presence of an extra bone growth core on the inner side of the navicular bone of the foot where the tibialis posterior tendon is attached.
The common symptoms for patients with this condition is swelling, pain and tenderness, often combined with a flatfoot deformity. Very often pain starts after long distance walking or impact sports activities like running, jumping, competitive ball games and frequent changes of running direction.
This condition classify as a congenital condition which is present from birth even though this cannot be seen in early x-rays due to cartilaginous nature of immature bones.
Orthotics can be used as a conservative treatment or other treatment for additional deformities. Related to individual findings and chronic pain, a minor surgical treatment with removal of accessory bone can be done with a short rehabilitation period with very good success rate.
