After fracture, if the local skin and soft tissues are intact and there is no obvious breakage or defect, internal fixation is generally recommended because internal fixation is a direct use of plates, screws, or interlocking intramedullary nails to fix the bone surface, which is much stronger than external fixation braces. In addition, after suturing the wound, there is usually no impediment to later functional exercise. The external fixation stent is generally necessary to put two thick screws on the two ends of the fracture, and the wound must be left on the skin surface. to do the fixation.
