钽金属治疗股骨头缺血性坏死的最新进展

股骨头缺血性坏死是骨科领域的一种常见病,常见病因为创伤、酗酒及激素应用等。目前治疗方法是早期减少坏死股骨头中心压力,后期行人工关节置换术,但都存在诸多缺陷和不足。多孔钽棒植入是近些年临床预防和治疗股骨头缺血性坏死的新疗法,它与成骨细胞有良好的生物相容性,通过植入股骨头软骨下对其提供有效的支撑,经过临床随访效果满意。该文对股骨头缺血性坏死的临床治疗方法及钽金属在这一疾病治疗中的现状予以综述。

New Development of Tantalum Treatment for Avascular Necrosis of the Femoral Head

Avascular necrosis of the femoral head is a common disease in the department of orthopedics.The common pathogeny includes trauma,intemperance,hormone application and so on.Relieve the pressure of the centre of necrotic femoral head at early stage and conduct hip replacement at later stage are the therapeutic methods at present,but both of them have lots of defects and disadvantages.In recent years,tantalum implantation has become a new therapeutic method for preventing and curing avascular necrosis of the femoral head in clinical practice.Tantalum and osteoblasts have a good compatibility,implanting tantalum under the cartilage of femoral head can provide effective sustain for the area of avascular necrosis,with satisfactory results during follow-up visits.Here is to make a review of the therapeutic methods of avascular necrosis of the femoral head and the application of tantalum treatment for the disease in clinical practice.
