Patient's question:
My father-in-law has been experiencing significant weakness in his lower limbs recently and has difficulty standing steadily. A thorough examination revealed that he has avascular necrosis of the femoral head. What are the causes of avascular necrosis of the femoral head?Doctor's answer:
Avascular necrosis of the femoral head is a difficult-to-treat orthopedic disease. The main causes include long-term use of high-dose corticosteroids and excessive alcohol consumption. These factors lead to the obstruction of blood vessels supplying the femoral head, resulting in avascular necrosis of the femoral head. Rest is essential. Maintain good deep sleep. Hip joint pain is the main symptom of avascular necrosis of the femoral head, which can radiate to the front and lateral side of the thigh. Pain is more pronounced during movement. In severe cases, the femoral head may collapse and deform, severely affecting hip joint function. If there is no relief or the condition worsens, it is necessary to seek medical attention promptly to identify the cause. Maintain a positive mood. Consume more fruits and vegetables daily to aid digestion and stay hydrated.
