Avulsion fractures of the navicular bone are relatively minor among fractures and are not considered serious. Avulsion fracture of the navicular bone is usually a tear of the tendon or ligament at the fracture site, and the displacement is usually small. It can be treated with plaster fixation, and most of the patients can be cured by conservative treatment. If the displacement is large, surgery is needed, and this kind of fracture is mostly fixed by absorbing screws or square head screws.
