摘　　要：踝关节扭伤是临床上常见的关节类运动性软组织损伤,但由于踝关节结构的复杂性,进行摇拔戳手法治疗时难以对其内部进行量化研究。则基于成年男性患者CT图像和踝关节解剖特点建立足踝有限元模型,并应用运动捕捉技术获取摇拔戳手法治疗踝关节的运动学参数,模拟力学状况进行有限元加载计算,计算的运动角度结果与实际临床数据基本一致,表明模型有效。通过有限元进一步分析得到踝关节扭伤治疗后较治疗前踝穴关节面应力增大、损伤韧带的弹性模量减小等量化结果。仿真结果表明:利用有限元方法能够较好模拟摇拔戳手法的力学状况,可直观看出踝关节扭伤治疗前后韧带参数、关节面受力的变化,将治疗效果进行量化,为研究该手法的作用机理提供科学客观的依据。Ankle sprain is a common joint soft tissue injury in the clinic.Due to the complexity of the ankle joint structure,it is difficult to quantify the internal changes during the manipulation.According to the CT images of adult male patients and the ankle anatomical features,the finite element model of the ankle was established,and the kinematic parameters of the ankle joint were obtained by the motion capture technique.The finite element loading calculation was simulated by simulating the mechanical condition.The calculated motion angle results are basically consistent with the experimental data,and the verification model is valid.Further analysis showed that after the ankle sprain treatment,the joint surface stress of the axillary point was increased and the elastic modulus of the injured ligament was decreased.The simulation results show that the finite element method can better simulate the mechanical condition of the shaking and pulling method.It can visually see the changes of ligament parameters and joint surface forces before and after the treatment of ankle sprain,which can quantify the therapeutic effect.The mechanism of action provides a scientific and objective basis.
