Accessory Navicular Syndrome

Accessory Navicular Syndrome

What is it? This is a bony prominence located on the midfoot region or the midtarsal region of the foot. It is usually painful. It occurs in conjunction with flat foot deformities. Due to the attachment of the posterior tibial tendon in the area, this problem can be diffucult to treat conservatively and surgical treatment may be nessesary in extreme conditions.

IIb: inferior placement of the accessory bone.
Type III: Enlarged navicular tuberosity
