Patients with femoral head necrosis should try to sleep in a flat position, not in a side-lying or prone position, which will cause the femoral head to be squeezed more severely and have more serious consequences. When sleeping, try to sleep on a hard bed. When the patient wants to turn over, he can gently turn on his side and put a soft cushion under the femoral head, and the time spent on his side should not be too long. When the symptoms of femoral head necrosis are serious, try not to lie on your side. You can place a functional pillow next to the femoral head to prevent the femoral head from being squeezed due to the patient’s activities while sleeping. In daily life, try not to do exercises that put pressure on the femoral head, do not walk for a long time, do not bend over, and do not walk fast. At the same time, we should pay attention to local warmth to avoid getting cold and chill, which will make the femoral head necrosis more serious.
