ABSTRACT

Incorrect treatment for femur head necrosis can cause collapse of femoral head and tresult in severe harm for the patients (especially for the patient with middle-aged and young). The structure and mechanics characteristics of tantalum rod is similar to bone tissue, it higher strength and can adapt the internal environment of organism, so it has a large potency in treating femur head necrosis. Treatment of early femur head necrosis with tantalum rod implanting had alreadly widey applied at home and abroad, the method has the advantages of simple operation, little risk, less complication and beseems the patient with stage I - II of ARCO. But reasons that the difficult diagnosis of early femur head necrosis, localized effect of tantalum rod, different experience of medical worker,caused the contentions about effect of tantalum rod implanting. With development of science, tantalum rod implanting combined with correlative biotechnology should raise the effect in treating femur head necrosis.
