If a fracture has occurred, surgery should be actively performed and the rational use of internal fixation should be recommended, because the long duration of conservative treatment can increase the risk of decubitus ulcers, pulmonary infections, thromboembolism, muscle atrophy, etc., while aggravating disuse osteoporosis and forming a vicious circle. The choice of surgical method should take into account the convenience of early postoperative activity and comprehensive treatment through physical therapy, physiotherapy psychology, nutrition, calcium supplementation, pain relief, promotion of bone growth, containment of bone loss, and improvement of immune function and overall quality.
