Fractures of the femoral head or the femoral neck are both prone to femoral head necrosis, and the chances of necrosis after a femoral head fracture are higher than after a femoral neck fracture. Because of the anatomical structure of the femoral head, which is completely inside the joint cavity, even after surgery, the establishment of blood circulation is very slow and difficult, and the chance of necrosis of the femoral head even reaches more than 70% in particularly severe comminuted femoral head fractures. Therefore, if you have a femoral head fracture, you should try to fix the fracture and give it a chance to heal as much as possible. If the fracture is treated conservatively, the chance of necrosis is higher and the possibility of non-healing is greater.
