The proximal end of the fracture should be fixed first, followed by the distal end. The fracture can be restored to its normal state by the action of the brace. The fracture can be fixed by splinting, plaster brace fixation and brace fixation, and it needs to be evaluated for nerve injury and important vascular injury before the manual repositioning, and timely treatment. After fracture, it is also necessary to decide whether to give conservative treatment or surgery according to the status, type and degree of injury. Conservative treatment is mainly for fractures with good stability and good alignment, and patients can be treated conservatively by external fixation with braces or casts. For serious fractures, comminuted fractures, and unstable fractures, timely surgical treatment is required.
