目的:利用有限元方法比较3枚交叉桥架埋头钉和锁定接骨板(锁定钢板)固定MasonⅢ型桡骨头骨折的生物力学稳定性。
方法:利用逆向建模技术,将1例25岁健康男性青年桡骨CT数据及内固定数据导入相关软件,分别建立MasonⅢ型桡骨头骨折的3枚交叉桥架构型埋头钉与锁定钢板的三维有限元模型,对桡骨头进行100 N轴向加载,比较两组模型最大位移、内固定上最大Von Mises 应力及应力分布等指标。
结果:3枚交叉桥架埋头钉组和锁定钢板组最大位移分别为0.069 mm和0.087 mm,内固定上Von Mises 应力峰值分别为18.59 MPa和31.85 MPa,3枚交叉桥架埋头钉组应力分布更加均匀。
结论:两种内固定方式均能提供良好的固定强度,3枚交叉桥架埋头钉较锁定钢板固定方式更具稳定性,应力分布更均匀。 |

Abstract:
Objective To compare the biomechanical stability of three cross-bridge headless compression screws and locking plates in the fixation of Mason type Ⅲ radial head fractures by finite element method.
Methods Using reverse modeling technology,the radial CT data and internal fixation data of a healthy 25-year-old male were imported into the relevant software. Three-dimensional finite element model of 3 cross-bridge headless compression screws and locking plates for MasonⅢ radial head fractures were established,and the radial head was loaded with 100 N axial loading. The maximum displacement,maximum Von Mises stress and stress distribution of the two groups were compared.
Results The maximum displacements of the three cross-bridge screws group and locking plate group were 0.069 mm and 0.087 mm respectively,and the Von Mises stress peaks were 18.59 MPa and 31.85 MPa respectively. The stress distribution of the three screws group was more uniform.
Conclusion Both internal fixation methods can provide good fixation effect. CoMPared with the locking plate fixation method,the 3 cross-bridge headless compression screws fixation is more stable and the stress distribution is more uniform. |
