Femoral intertrochanteric fracture, also known as femoral intertrochanteric fracture, is a common low-energy injury in the elderly, with the aging of society and the increase of per capita life expectancy, the incidence of femoral intertrochanteric fracture is on the rise, the hip is a good site for osteoporotic fractures in the elderly, the average age of patients with intertrochanteric fracture is 5-6 years higher than that of patients with femoral neck fracture, 90% occur in elderly people over 65 years old, and the incidence over 70 years old The incidence increases sharply over the age of 70. In the eyes of most people, fractures do not kill, but for the elderly, a fracture of the trochanter may be the last blow of their lives. Due to the fracture, the elderly lose the ability to stand, walk or even move in bed. If conservative treatment is used, the patient has to be bedridden for a long time, and long-term bedridden for elderly patients is more likely to cause the decline of heart and lung and other important organ functions, and complications such as crushing pneumonia, decubitus ulcer, urinary stones, deep vein thrombosis of lower limbs, pulmonary embolism, etc. Once these complications occur, due to the fracture Although fractures do not cause death, the complications of long-term bed rest will seriously threaten the life of the elderly. According to statistics, the mortality rate of patients with intertrochanteric fractures treated conservatively is as high as 30% after one year. In addition, the incidence of deformed healing, delayed healing, and nonunion is significantly higher after conservative treatment, making it more likely that serious functional impairment will remain. In addition to the physical and psychological pain, intertrochanteric fractures have become a heavy burden for individuals, families and society due to the high cost of medical and nursing care caused by prolonged bed rest. Although DHS (dynamic hip screw) and PFNA (intramedullary fixation) can achieve satisfactory fixation temporarily, it takes time for the fracture to heal; meanwhile, because of the severe osteoporosis in elderly patients, internal fixation failure and deformity may occur during the healing process. For advanced age and osteoporotic heavy intertrochanteric fracture, our department adopts bone cement type long stem hemi hip replacement, which can make the patient get a painless and functional joint at an early stage, without waiting for bone healing, and can go to the ground at an early stage, which obviously reduces the discovery of complications and achieves satisfactory results. Experts remind that even in advanced age but with good bone quality, internal fixation is still preferred for intertrochanteric fractures of the femur.
