Objective:The operation process of support and implantation of tantalum rod for necrosis of the femoral head is simulated. Three-dimensional finite element model of support and implantation of tantalum rod for necrosis of the femoral head is established and the stress distribution of axial force of the femur is simulated. Methods:There is 1 case of ARCO II femoral head necrosis of adult female patient. The pelvis is scanned with CT. MIMICS 15.0 is used for three-dimensional reconstruction of pelvic. According to operation requirements, Pro/Engineer 5.0 is used to design 3D model of Kirschner pin and tantalum rod. And then the operation process of support and implantation of tantalum rod is simulated. And then ANSYS 12.0 is used to establish finite element model for support of tantalum rod for necrosis of the femoral head. Results:The location, shape and size of the necrotic area are reconstructed. The operation process of support and implantation of tantalum rod is simulated. A total of 129,968 nodes and 92,426 units of finite element model are established for support and implantation of tantalum rod for necrosis of the femoral head. Conclusion: High simulation digital model is provided for decision-orientated study and clinical teaching with clear objective; high-accuracy finite element is provided for operation simulation and biomechanical analysis before operation.
