The principles of treatment for hip fractures occurring in 85-year-old elderly people are as follows: First, if the patient is in poor general condition or has a combination of serious heart, lung, kidney, liver and other dysfunctions, conservative treatment should be considered. Usually, anti-rotation shoes can be worn, continuous skin traction of the lower limbs, and bed rest for 6-8 weeks, and isometric contraction training of the quadriceps and ankle flexion and extension activities can be started. During the bed rest period, the patient should not lie in the lateral position and the affected limb should not be inducted to avoid fracture displacement. After eight weeks, the patient can sit up in bed, and after three months, the patient can gradually leave the bed with the help of crutches and walk without weight. In about six months, the fracture will be firm and healed, and the patient can return to normal life. Secondly, if the head-down fracture occurs or the general condition is good, early surgery can also be considered to enable the patient to turn in bed autonomously to avoid serious bed-ridden complications such as decubitus ulcer and pneumonia.
