Left femoral neck fracture is mostly treated by surgery, but for those who are in poor condition and cannot tolerate surgery, conservative treatment can be used. 1. Surgical treatment: including closed reduction internal fixation, incision reduction internal fixation, artificial joint replacement and other methods. Patients with internal fixation treatment should avoid weight bearing for one year after surgery to avoid ischemic necrosis of the femoral head. Artificial joint replacement patients should have early rehabilitation after surgery to avoid adhesion. 2. Conservative treatment: mainly wearing anti-rotation shoes, skin traction or tibial tuberosity traction treatment for 6~8 weeks. Since conservative treatment patients have to stay in bed for a long time, attention should be paid to avoiding pressure ulcers and preventing local infection at the traction site. When left femoral neck fracture occurs, you should seek medical treatment in time, according to your own situation and under the guidance of the physician to avoid delaying the condition.
