Without knowing the early symptoms of osteonecrosis of the femoral head, many people may not pay attention to osteonecrosis of the femoral head. In fact, early treatment of osteonecrosis of the femoral head is the most beneficial to the recovery of the disease. What are the common early symptoms of femoral head necrosis? The early symptoms of femoral head necrosis are: pain in the lower back, pain in the affected hip, pain in the groin area, pain in the knee joint, fear of the affected limb, weakness and soreness when moving more, easy fatigue, etc. Lower extremity cold fear is always a symptom of lower extremity coldness, which appears at the same time with the lower extremity weakness symptom of early symptoms of femoral head necrosis. In a period of time, the patient feels cold in the lower extremities and does not dare to wear too little on the lower body, there is always some cold feeling, and the temperature is slightly low, both lower extremities can feel it most sensitively, especially to the air conditioner and electric fan. The early symptoms of femoral head necrosis can be examined by X-ray, which is a planar imaging of the femoral head and mainly looks at the appearance of the femoral head. In the early stage of femoral head necrosis, X-rays can only see the reduced blood circulation around the femoral head and a small amount of cystic changes, which cannot accurately reflect the changes in the bone cells of the femoral head, and can only be seen on X-rays when the femoral head necrosis has developed to the middle and early stage. The early symptoms of osteonecrosis are not all in the hip joint, and the frequency of occurrence varies, with a few days of symptoms and a few days of no symptoms, and will disappear on their own without treatment. These early symptoms of osteonecrosis of the femoral head usually do not appear in one patient at the same time, so it is difficult for inexperienced orthopedic surgeons to make a correct judgment of osteonecrosis of the femoral head at an early stage, which is the reason for the high rate of misdiagnosis of early symptoms of osteonecrosis of the femoral head.
