Whether the fracture is displaced again after the fracture, mainly based on clinical symptoms and related auxiliary examination to determine: 1, the previous pain, swelling and other related symptoms gradually reduce, if there is external injury or weight bearing, these symptoms reappear and become more and more serious, suggesting that the possibility of displacement is relatively large. 2, according to the relevant auxiliary examination, if the latest radiographs show and the last fracture without dislocation comparison, it will be able to clearly find out whether there is a problem of displacement. If the latest radiograph shows no dislocation with the previous fracture, it will be able to clearly find out whether there is a problem of dislocation. At this time, according to the characteristics of the dislocation, we should choose whether we need to correct the manipulation of restoration, or directly carry out surgery to fix the fracture site. This is because in cases of obvious malalignment the fracture may affect healing, or lead to malunion, which may affect the function of the area.
