Fractures of the navicular bone of the foot, if there is a comminuted fracture of the girdle of the navicular bone or of the body of the navicular bone, the local blood circulation is not very good, and there is a possibility of slow growth of the bone or of bone nonunion or osteonecrosis. Therefore, the above fractures must be correctly anatomically repositioned, surgically cut and repositioned, and the fracture ends fixed using screws or Kirschner pins. After surgery, the fracture must be immobilized with a plaster cast, and the fracture must be treated with bone-growing medications and physical therapy to promote recovery, and it takes 3 months to see the growth of a bone scab. In the case of avulsion fracture of the navicular bone with a rim, the effect on blood circulation is not too great in this case. If there is no malalignment, immobilization can be given for about 4 weeks.
