摘要:
目的:通过有限元分析,对比锁定钢板固定和普通钢板固定治疗跟骨骨折的临床疗效。方法:通过CT扫描得到健康成年男性左侧跟骨数据,利用Mimics10.0软件、Solidworks2010三维设计软件及Ansys12.1有限元分析软件制成跟骨骨折锁定钢板固定和普通钢板固定有限元模型,分析二者在640 N、1 280 N、2 560 N及5 120 N载荷下的峰值应力、总位移和关节面蹋陷方向位移。结果:锁定钢板固定模型在不同载荷下的峰值应力、总位移和关节面蹋陷方向位移均小于普通钢板固定模型。随着载荷的倍增,锁定钢板固定模型的峰值应力、总位移和关节面蹋陷方向位移值变化不大,普通钢板固定模型的相应指标随载荷的倍增近似成倍增加。结论:对于跟骨骨折,锁定钢板固定在峰值应力、稳定性和防止跟骨垂直方向蹋陷方面优于普通钢板固定。
Abstract:
Objective:To compare the clinical curative effect of internal fixation with locking plate with that of internal fixation with common plate in the treatment of calcaneal fractures through finite element analysis.Methods:The data of left calcaneus of normal adult males were collected through CT scans,and the Mimics10.0 software,Solidworks2010 software and Ansys12.1 software were used to build the finite element models of internal fixation in calcaneal fractures with locking plate and common plate,respectively.Such parameter of the models were analyzed as the peak stress,total displacement and displacement in the direction of collapse of articular surface under the load of 640 N,1 280 N,2 560 N and 5 120 N,respectively.Results:The peak stress,total displacement and displacement in the direction of collapse of articular surface for models of fixation with locking plate were all less than those for models of fixation with common plate.Along with the multiplication of loads,little change were found in the peak stress,total displacement and displacement in the direction of collapse of articular surface for models of fixation with locking plate,while above mentioned indexes doubled approximately for models of fixation with common plate.Conclusion:Fixation with locking plate is better than fixation with common plate in the peak stress,stability and prevention of calcaneus collapse in vertical direction for the calcaneal fractures.
