When a fracture occurs, the first step is to clarify whether the alignment of the fracture is good, that is, to take X-rays first, as follows: 1. Plaster fixation: If the alignment of the fracture is good, you can use plaster fixation, and the lower limb must be elevated during the plaster fixation, which is conducive to the swelling. If the fracture is not well aligned and aligned, the fracture should be repaired by manipulation, and after the fracture is repaired by manipulation to achieve the ideal alignment and alignment, the cast can be applied. 2. Surgery: If the fracture does not reach the ideal position during the repositioning by manipulation, the fracture should be treated surgically by internal fixation with plate and screw. It does not need to be fixed.
