The head-preserving treatment of femoral head necrosis is a recognized problem, and there is a lack of effective drug treatment measures. In recent years, we have achieved better results in the treatment of early femoral head necrosis by using femoral head marrow core decompression compounded with autologous stem cell transplantation. The mechanism of this treatment for femoral head necrosis is: through a minimally invasive channel in the femoral neck, we use a spatula to scrape away the necrotic and cystic lesions of the femoral head, thus reducing the necrosis and pain of the bone tissue caused by the increased pressure due to edema in the femoral head and improving the blood flow in the necrotic area of the femoral head; in addition, we extract the patient’s own bone marrow tissue before surgery, concentrate it and then extract our own bone marrow stromal stem cells, which have These cells have a strong differentiation function and are compounded into tricalcium phosphate artificial bone scaffold material and implanted into the necrotic area of the femoral head through the femoral neck channel. This procedure is a minimally invasive treatment in which an incision of approximately 3 cm is made in the greater trochanter of the femur and the procedure is performed under fluoroscopy. The entire procedure takes about half an hour, and the patient can get up early and move around after the surgery, with a quicker recovery.
