Tension-Free Weight-Bearing Immobilization in Steroid-Induced Osteonecrosis of the Femoral Head Albino Rat Models

To establish a steroid induced osteonecrosis of the femoral head, or SONHF model, use an albino rat. Intraperitoneally inject lipopolysaccharide into the midline of the rat's abdomen every 24 hours. After the last lipopolysaccharide injection, inj
