    ABSTRACT: In current study of femoral head necrosis and femoral neck fractures, more attentions has been paid to relationship between the femoral head trabecular bone within the spatial structure and its biomechanics. In this connection, PMMA (polymethyl methacrylate), special square iron, dental base acrylic resin liquid and powder were used to embed and fix human dry femur. Then, M618 Lie Axle Rectangle Desk Plane Grinding Machine was applied to grind the femur specimen, and then air blower clean, two-dimensional cross section image was obtained by using scanner. With Mimics software reconstruction, a three-dimensional model of spatial structure of trabecular bone was obtained, and the trabecular bone three-dimensional parameters were calculated. The authors obtained clear three-dimensional model of trabecular bone, reconstructed the real anatomic morphology of proximal femur. This is a good method to research into the interior structure of femur and to provide the foundation for the three-dimensional finite element analysis.
