摘要:
目的:基于有限元模型分析外侧踝关节扭伤“骨错缝、筋出槽”的病理状态。方法:基于1位外侧踝关节扭伤患者的CT资料,建立踝关节有限元模型并验证模型的有效性。采集踝关节扭伤后1 d、1周的在体动力学数据并加载于踝关节有限元模型跖屈、背伸、内翻、外翻四种工况中,分析踝关节面受力及踝周韧带的应力分布情况。结果:在相同的载荷下,四种工况中踝关节(胫距、距腓关节)面接触应力峰值在踝扭伤后随着时间的变化有增高的趋势,四种工况中踝周韧带在踝扭伤后不同时间点的应力分布及应力值存在变化。结论:所建立的踝关节有限元模型准确、有效,踝部关节面受力分布不均匀及韧带应力值的变化可能是外侧踝关节扭伤“骨错缝、筋出槽”的客观病理反映。
Abstract:
Objective:To demonstrate the pathological state about “joint displacement and sinew off-position” of lateral ankle sprain based on finite element model.Methods:Based on the CT data of a patient with lateral ankle sprain,the finite element model of ankle joint was established and verified.The biomechanical data were collected and loaded into the ankle finite element model of plantar flexion,dorsal extension,varus and valgus at 1 day and 7 days after injury,then the stress distribution of ankle joint surface and peri-ankle ligament was analyzed.Results:Under the same load,the peak contact stress of ankle joint(tibiotalar joint and talofibular joint)increased with time after ankle sprain,and the stress distribution and value of peri ankle ligament changed at different time points after ankle sprain.Conclusion:Based on the accurate and effective finite element analysis of ankle joint,the uneven stress distribution of ankle joint surface and changed ligament stress value may be the objective pathological reflection of “joint displacement and sinew off-position” of lateral ankle sprain.
