目的: 探讨个性化锁骨近端解剖钢板螺钉固定有限元模型建立及有限元分析。
方法: 选择1例40岁男性健康志愿者,运用三维重建软件Mimics 15.01软件,Hypermesh 2019及Abaqus 2020软件的有限元分析模块,初步建立锁骨近端解剖钢板有限元模型并在锁骨长轴远端15 mm位置处施加250 N垂直方向的载荷观察整体结构,钢板、螺钉位移云图,Mises stress应力分布等有限元分析数据。
结果: 整体结构位移分布可看出最大的位移分布在锁骨远端,正常人体上肢重量,锁骨纵行、斜行骨折及摔倒时肩部撞击暴力、锁骨纵行、斜行骨折4种条件下最大位移分别为1.04、1.03、1.35、1.33 mm;从钛合金钢板位移云图中可知最大的位移分布在靠近锁骨远端位置,最大位移分别为0.89、0.88、1.10、1.09 mm。从钛合金螺钉位移云图中可知最大的位移分布在远端螺钉的根部,最大位移分别为0.88、0.87、1.08、1.06 mm。Mises Stress应力分布来看最大的应力主要分布在钛合金钢板和螺钉上,锁骨上的应力非常小。从应力分布云图中可以观察钢板最大主应力分布在锁骨近端第2排螺孔位置,最大的Mises应力分别为673.1、678.1、648.5、654.4 MPa,钛合金螺钉最大应力分别为414.5、417.4、415.8、419.7 MPa。
结论: 利用计算机模拟三维有限元计算方法表现个性化锁骨近端解剖钢板的生物力学变化,为个性化锁骨近端解剖钢板提供生物力学数据。 |

Abstract:
Objective To explore establishment and finite element analysis of personalized proximal clavicular anatomical plate screw fixation model.
Methods A 40-year-old male healthy volunteer was selected and the finite element analysis modules of 3D reconstruction software Mimics 15.01,Hypermesh 2019 and Abaqus 2020 were used. The finite element model of anatomic plate at the proximal clavicle was established,and a vertical load of 250 N was applied to the distal end of long axis of clavicle about 15 mm,then the overall structure,plate and screw displacement cloud image,Mises stress distribution were observed.
Results The displacement distribution of the overall structure shows the maximum displacement was distributed on the distal clavicle. Under the four conditions of normal upper limb weight,longitudinal clavicle fracture,oblique fracture and shoulder impact violence during fall,longitudinal clavicle fracture and oblique fracture,the maximum displacement were 1.04 mm,1.03 mm,1.35 mm and 1.33 mm,respectively. The displacement cloud map of titanium alloy steel plate showed the largest displacement was distributed near the distal clavicular bone,and the maximum displacement were 0.89 mm,0.88 mm,1.10 mm and 1.09 mm,respectively. The displacement cloud map of titanium alloy screw showed the largest displacement was distributed at the root of the distal screw,and the maximum displacement were 0.88 mm,0.87 mm,1.08 mm and 1.06 mm,respectively. Mises stress distribution showed the maximum stress was mainly distributed on titanium alloy plates and screws,and the stress on the clavicle was very small. Mises stress distribution cloud showed the maximum Mises stress was distributed at the second row of screw holes near the clavicle,and the maximum Mises stress were 673.1,678.1,648.5,654.4 MPa,respectively. The maximum stresses of titanium alloy screws were 414.5,417.4,415.8 and 419.7 MPa,respectively.
Conclusion The biomechanical changes of personalized proximal clavicular anatomical plates are demonstrated by using 3D finite element method to provide biomechanical data for personalized proximal clavicular anatomical plates. |
