You can’t turn over immediately after femoral head surgery, usually you can turn over passively on the 2nd day, the time to turn over on your own is different according to different surgeries, usually it takes about 2~4 weeks to turn over on your own. There are two types of femoral head surgeries: core decompression and artificial hip replacement. 1. Core decompression surgery: Core decompression surgery is to cure femoral head necrosis by lowering the pressure of the femoral head’s medullary cavity, so as to reopen the locally occluded small blood vessels and increase the blood supply to the femoral head. Generally, you can turn over by yourself in about 4 weeks after the operation. 2. Artificial Hip Replacement: Total hip replacement, removing the necrotic femoral head and using an artificial joint to solve the problem of necrosis of the femoral head. Generally, the wound heals in about 2 weeks after the operation, and then you can turn over on your own. Turning over early after femoral head surgery can prevent complications such as pressure sores, lung infections, intestinal obstruction, etc. However, according to the patient’s recovery, turn over under the guidance of the doctor to ensure the stability of the bone, and do not operate on your own, so as to avoid the occurrence of joint dislocation and other accidents.
