Steroid-induced osteonecrosis of the femoral head (ONFH) has the incidence of 9-40% in patients receiving long-term treatment and is mainly involved in the middle and young people. It is mostly bilateral, with a wide range of necrosis and high disability rate, which brings disaster for patients and families. The experimental study shows that autophagy participates in the pathological process of steroid ONFH and is closely related to apoptosis, and the interaction between autophagy and bone cells is related to the dose of hormones. Moreover, autophagy also affects the interaction between osteoblasts and osteoclasts in ONFH. In the present review, we have discussed the role of autophagy in the pathological process of the steroid-induced ONFH.
