Fractures of the femoral neck often occur in the elderly, and their incidence is increasing as people live longer. There are two main problems in its clinical treatment: fracture non-union and ischemic necrosis of the femoral head. When the femoral neck in the elderly is usually combined with osteoporosis, a slight twisting fall, such as in a slippery bathroom, unsteady stairs and getting out of bed, may cause a fracture. Treatment timing Early treatment is beneficial to recover from post-fracture vascular compression or spasm as soon as possible. In principle, surgery for femoral neck fracture should not take more than 2 weeks. Accurate and good fracture repositioning is an important condition for bone healing. Traction on the affected limb, while adding counter-traction at the root of the thigh, and after the original length of the limb is restored, perform internal rotation and abduction repositioning. The first challenge for osteoporotic femoral neck fractures is to decide on the most suitable surgical option for the patient. However, it is important to prevent the fracture from failing to heal due to osteoporosis and insufficient fixation strength, or from necrosis of the femoral head due to ischemia. Sometimes a hemi- or total hip replacement is also used. Early ambulation is possible. Risk factors for why joint preservation can fail include the patient’s advanced age, the degree of osteoporosis, the location of the fracture, the direction of the fracture, and the greater degree of displacement of the fracture. Correct functional exercise can improve the blood circulation of the whole body and local area, and the activity can improve the blood supply of hip muscles and hip joint, prevent muscle atrophy, and keep the good movement function of hip joint is beneficial to the healing of femoral neck fracture. It can also promote the enhancement of gastrointestinal motility and increase appetite to prevent osteoporosis in the elderly. For fresh fractures with closed internal fixation, the foot should wear “Ding” shoes to prevent external rotation of the affected limb and to avoid affecting the stability of the fracture due to rotation of the fracture end. After internal fixation, you can rest in semi-recumbent position and start to exercise quadriceps and dorsiflexion and plantarflexion of ankle joint, and forbid to do hip inversion activities to prevent muscle atrophy, joint stiffness and fracture re-displacement. 4-6 weeks later, you can do active or passive hip and knee exercises in bed, but should not do hip inversion and external rotation exercises. 2-3 months walking exercises with the help of crutches, generally should not bear weight too early. Before the fracture heals, in order to prevent the hip joint from internal deformation and to facilitate the fracture healing, do not cross your legs, do not lie on your side, and do not get off the ground.
