Minor avulsion fractures are common and usually require no specific treatment.
Isolated fractures of the navicular are uncommon.If undisplaced, these would normally be managed conservatively. Displaced fractures require an orthopaedic opinion and consideration of ORIF.
Fractures of the navicular may occur in association with dislocations of the mid-foot. Any significant injury in this area requires a lateral x-ray of the foot in addition to normal foot x-rays. If there is concern about a dislocation, a CT is required.
