Perforation of necrosis of the femoral head can usually be recovered with regular treatment and rehabilitation. Perforation of femoral head necrosis generally refers to medullary core decompression. It is a direct access to the femoral head through the path around the femoral head, in order to reduce the pressure in the femoral head through the decompression orifice, and improve the symptoms of osteonecrosis of the femoral head due to the increase of internal pressure. It reduces internal bone pressure, relieves pain, improves venous return, and helps blood vessels grow in. As it is not irreversible surgery, it is to go to regular hospitals to receive treatment and follow the doctor’s instructions for recovery after surgery. During the recovery period, rest should be paid attention to, and activities under the bed should be carried out under the care and help of family members. After the operation, rehabilitation training should be carried out under the guidance of doctors at the appropriate time to prevent the patients with necrosis of the femoral head from having wasting muscle atrophy. It is recommended that patients who need core decompression surgery for necrosis of the femoral head should go to regular hospitals and under the correct operation of doctors.
