镁合金与钛合金接骨板固定股骨中断骨折的有限元分析
Finite element simulation of femur fracture healing by magnesium alloy and titanium alloy
摘要
Abstract
To explore the similarities and differences of mechanical properties in AZ31 magnesium alloy and traditional titanium in treating femoral fracture,we conducted three-dimensional recon-struction of the femur by human femur CT image,imported the model into ANSYS,then mod-eled plates and bone screws,and carried out finite element analysis.Magnesium alloy was as the experimental group and titanium was the control group.Fracture period,early healing period,and late healing period were simulated.The stress of 8 key points in plate and femur were extracted and analyzed.The results showed that four key points on the femur of the titanium control group were compressed in the bone healing period,while four key points on bone plate is stretched.As the fracture healing,the value of key points in bone plate reduces,the value of key points in femur increases.The results of magnesium alloy experimental group were similar to the titanium control group,while the data of magnesium group was larger than that of titanium group.In conclusion in the bone healing period,the medial femur is compressed,and the side with plates is stretched. The regularity of 8 positions on the magnesium alloy plates are consistent with that on the titani-um plates.With the gradual healing of fracture,the stress of medial femur increases,while the stress of the side with plates decreases.The magnesium alloy plates and the titanium plates have similar mechanical properties in the process of fracture treatment.关键词
