Early signs of osteonecrosis of the femoral head are not obvious and are not easily taken seriously. It may be cured through surgical treatment. Necrosis of the femoral head, with atypical early symptoms, mainly manifests as pain or soreness in the hip or groin area, which can be relieved after resting, and there are also cases of acute onset. Hip necrosis can choose surgical treatment and non-surgical treatment, but necrosis progresses faster, non-surgical treatment is not effective, most patients will finally choose surgical treatment. That is, hip preservation treatment or artificial hip replacement, patients can achieve the expected life expectancy. Patients who have already suffered from femoral head necrosis should control their weight, reduce the use of glucocorticosteroids, avoid overwork and strenuous exercise, and consume more high-calcium and high-protein foods in their diet.
