股骨头部分置换术精准微创治疗ARCOⅢ期股骨头缺血坏死的实验研究

Experimental study on precise treatment of ischemic necrosis of femoral head in ARCO stageⅢby partial femoral head replacement

采用尸体髋关节标本对股骨头部分置换术进行实验性研究,初步评估该手术的可行性。课题组在2例成年髋关节标本上分别模拟股骨头部分置换手术,在C形臂监测下,使用空心环钻,沿股骨颈方向建立骨隧道,取出负重顶区死骨(模拟),制作骨缺损区,将合适尺寸的股骨头假体置入该区,影像学结果显示股骨头假体与骨缺损区周缘骨的匹配良好,初步认为该方法具备一定可行性。

To evaluate the feasibility of partial replacement of femoral head with cadaveric hip joint specimens.In two cases of specimens of adult hip portion of simulated femoral head replacement surgery,un-der the C arm monitoring,using hollow trephine,build bone tunnel along the direction of the femoral neck,remove the weight-bearing area dead bone(simulation),making bone defect area,the appropriate size of the femoral head prosthesis into the area and imaging results show that the femoral head prosthesis and bone de-fect area peripheral bone matching is good.Preliminary results show that this method has certain feasibility.
