Necrosis of the femoral head does not usually cause necrosis of other bones, but may cause joint damage. Necrosis of the femoral head occurs when the blood vessels supplying the femoral head become diseased, resulting in impaired blood and oxygen supply to the femoral head, and ultimately causing ischemic necrosis of the femoral head, which is commonly seen in fractures of the neck of the femur, prolonged alcohol consumption, and hormone use. Other bones are less likely to develop necrosis because they have a different vascular supply system. Necrosis of the femoral head can lead to degenerative changes in the acetabulum, which can cause serious damage to the articular cartilage, and in the later stages, osteoarthritis of the hip joint is very likely to occur. In case of necrosis of the femoral head, you should consult a doctor in time to find out the cause of the disease and standardize the treatment under the doctor’s guidance in order to get well soon.
