How to treat a comminuted humerus fracture depends on the situation. First, if it is an elderly patient, particularly old, over 80 years old with a comminuted humerus fracture, this time is usually treated by conservative treatment, such as cast fixation with an abductor or external fixation with a brace. The fracture can be stabilized after 6-8 weeks of treatment. 8-12 weeks, the fracture can basically heal. Second, for young people, most of the comminuted humerus fractures need to be treated surgically because comminuted fractures are unstable, easily displaced, and even not easily healed, so incision and internal fixation are usually required. Thirdly, if the powder if a comminuted fracture, the fracture displacement is not too obvious, and at the same time may be combined in the own disease, such as severe hypertension, coronary heart disease, diabetes, not suitable for surgery, then also can be conservative treatment. Therefore, the specific treatment of comminuted fractures of the femur cannot be generalized. In particular, if there is a combination of open comminuted fracture and severe soft tissue defect, surgery is necessary and anti-infection and anti-inflammatory treatment may be required.
