Defendant of Femoral Neck Fracture: Hello, Liu Xingzhi. This situation requires surgical treatment according to the patient's physical condition. Interviewee with femoral neck fracture: If Liu Ming doesn't have surgery, he may always be on crutches. Femoral neck fracture can lead to femoral head necrosis, which is a disabling disease. Responder: Liu Mingjian needs femoral head replacement in principle when he is so old, as long as his body can bear it. What kind of respondent doctors will comprehensively analyze the classification of femoral neck fractures according to specific conditions? According to the shape of femoral neck fracture, Dr. Lin divided it into incarcerated fracture and dislocation fracture. The fracture lines of these two kinds of femoral neck fractures can be expressed as dense lines and/or transparent lines. Dense fracture lines indicate that the trabeculae of the two fracture ends overlap and embed, while transparent fracture lines indicate that the two fracture ends are separated. In addition, the fracture site can be divided into: under the head type: the fracture line is located at the junction of head and neck; Transcervical type: the fracture line is located in the middle of femoral neck; Basal type: the fracture line is located at the bottom of the femoral neck, mostly outside the joint capsule; Head and neck type: the upper end of the fracture line is under the head and the lower end is in the middle of the femoral neck. This kind of fracture has poor blood supply at the proximal end and is not easy to heal.
