摘要:
目的：运用有限元分析，探讨三角稳定固定系统对股骨颈骨折的生物力学特性。方法：选取1名健康青年志愿者，获取其股骨CT影像学资料，构建股骨三维模型及股骨颈骨折三维模型。运用Ansys12.1有限元分析软件，模拟人体直立情况下正三角、倒三角稳定固定系统对内固定物应力分布、骨折处位移的影响。结果：正三角内固定、倒三角内固定模型的股骨头最大等效应力接近，倒三角内固定模型的内固定物最大等效应力低于正三角内固定。正三角内固定、倒三角内固定模型的股骨近端、内固定物最大位移接近。结论：正三角、倒三角稳定固定系统的股骨头最大等效应力、股骨近端最大位移、内固定物最大位移接近，倒三角内固定模型的内固定物最大等效应力更低。 【关键词】三角稳定固定系统；股骨颈骨折；生物力学；有限元分析
Abstract:
Abstract: Objective To explore the biomechanical characteristics of femoral neck fracture with triangular stabilization and fixation system by finite element analysis. Methods The CT imaging data of the femur in a healthy young volunteer was obtained, and the three-dimensional models of the femur and femoral neck fracture were constructed. Ansys12.1 finite element analysis software was used to simulate the effects of regular triangular and inverted triangular stabilization and fixation systems on the stress distribution of internal fixator and the displacement of the fracture when human body was in upright posture. Results The maximum equivalent stress of femoral head in regular triangular and inverted triangular internal fixation models was similar, while the maximum equivalent stress of internal fixator in inverted triangular internal fixation model was lower than that in regular triangular internal fixation model. Moreover, the differences in the maximum displacements of proximal femur and internal fixator between regular triangular and inverted triangular internal fixation models were trivial. Conclusion There is no significant difference between regular triangular and inverted triangular stabilization and fixation systems in the maximum equivalent stress of femoral head, the maximum displacement of proximal femur and the maximum displacement of internal fixator, but the maximum equivalent stress of internal fixator in inverted triangular internal fixation model is lower.
