Glucocorticoid-induced osteonecrosis of the femoral head is one of the most common causes of osteonecrosis of the femoral head in clinical practice. It is caused by the disorder of lipid metabolism and the formation of small blood clots during the long-term use of large amounts of hormones, resulting in impaired blood circulation in the femoral head and osteoporosis in the femoral head, which eventually leads to a series of diseases such as necrosis and collapse of the femoral head. If this disease occurs, there should be a systematic examination to clarify the specific severity of femoral head necrosis. In the early stage, conservative treatment should be actively pursued, such as crutches, avoiding pressure on the femoral head area, completely avoiding hormonal drugs, and not drinking alcohol to prolong the life of the femoral head. If the femoral head necrosis reaches the middle and late stage and there is collapse, only total hip replacement surgery can be done.
