| Abstract(in English) | Although many studies of femoral fracture reduction have focused on long bone shaft fractures, proximal femoral fractures happen frequently especially for elderly people. In long bone shaft fractures, bone fragments have a common bone shaft axis which can be used as an indicator for repositioning, whereas in proximal femoral fractures, bone fragments have no such common axis and there is no clear indicator for repositioning. Previous study on proximal femoral fractures, the healthy contralateral femur model was used for repositioning, however, right and left femora have some asymmetry. Then, we propose a method of collating both the fracture lines and the shape of the contralateral femur. The fracture lines were extracted from bone fragments. In our experiment, the average error of reduction was 4.45mm and 3.83 degree when it took an initial value at 10mm 10 degree, 5.11mm and 6.95 degree when it took an initial value at 20mm 20 degree. |
