Accessory Navicular Wheeless (Visit this link)
accessory navicular is an accessory ossicle of the foot which is located on the medial side of foot, proximal to the navicular
and in continuity with the tibialis posterior tendon;
- approximately 2-12% of people may have this ossicle;
- accessory navicular generally does not ossify until 9 years of age, and in about one half of cases, the
accessory navicular will go on to fuse to navicular;
- a valgus stress injury may fracture the attachment of the ossicle to the navicular resulting in abnormal motion;
- insertion of major portion of tibialis posterior tendon into accessory bone displaces tendon, allowing foot
to deviate into a valgus position;
- this results in flatfoot w/ prominences of accessory bone& navicular;
