In clinical practice, if a comminuted femur fracture occurs, most of them are able to heal, but they must be under the correct guidance and treatment of the doctor to achieve the desired result. If a comminuted femur fracture occurs, rubbing or massaging the area is prohibited. It is important to go to the hospital in a timely manner, and after the doctor’s examination, and then assisted by the X-ray, CT film or nuclear magnetic film of the femoral stem to clarify the diagnosis and the degree of fracture comminution, and then consider the appropriate treatment. If the patient is in good health and the degree of fracture comminution is severe, surgical treatment can be considered, with intramedullary pin internal fixation being preferred. If the patient is weak and the vital signs are not stable, conservative treatment should be considered by giving traction to the lower extremity with local braking, fixation in a cast or brace, and regular review of X-rays.
