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, under 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 defect area peripheral bone matching is good. Preliminary results show that this method has certain feasibility.
