Case: A week ago, 79-year-old Mrs. Liu from Liu Bang’s hometown underwent bipolar artificial femoral head replacement surgery in our department for a right femoral neck fracture. According to the principle of fracture treatment, incisional internal fixation was preferred, and the family initially thought so too. The reasons why elderly patients with femoral neck fracture are not suitable for incisional internal fixation: 1. The surgery is more traumatic and bleeding. 2, long postoperative bed rest, can not be liberated from the bed early, many complications, most patients will be bedridden from then on. 3. Fractures of the femoral neck are difficult to heal and the incidence of secondary femoral head necrosis is high. The latest treatment concept for these patients is to treat them with the method that causes the least damage and pain and allows them to get out of bed as soon as possible. Bipolar artificial femoral head replacement surgery is the best choice for patients with this type of disease. This option can be chosen when the patient has fair internal organ function and good physical condition through preoperative evaluation. This method uses a small incision, which is characterized by less damage, less bleeding, shorter operation time, and the ability to get out of bed early. The relatives who came to visit the patient were happy to say: the old man could get out of bed within a week after the operation, I can’t imagine that he could recover so fast, so the elderly femoral neck fracture can be treated in this way.
