摘　　要：背景:目前足部有限元模型的材料特性和参数大多参考国外文献,尚未见国内开展材料参数的测试研究工作的报道。国内常用的方法用游标卡尺测量韧带、肌腱的宽度和厚度计算截面积。目的:设计一种测量韧带横截面积的新仪器,提高测量精度。方法:通过设计一种新型韧带横截面积测量仪器,分别应用该新型仪器与传统游标卡尺对5具新鲜尸体踝关节韧带横截面积进行测量,然后对两种测量方法进行对比分析。结果与结论:1游标卡尺测量组距腓前韧带、跟腓韧带、胫舟韧带、胫跟韧带的横截面积平均值分别为(20.61±7.52)、(22.38±11.49)、(33.09±9.91)、(28.20±10.88)mm2,新型韧带横截面积测量仪器为(17.59±4.03)、(20.77±7.91)、(28.08±8.14)、(30.39±7.98)mm2,两种方法测量结果差异均无显著性意义,结果相当。2结果说明,该新型韧带横截面积测量仪操作简便,测量结果较准确可靠,填补了韧带横截面积测量实验无专用仪器的空白,其应用价值值得进一步研究。BACKGROUND：There is a lack of study on material properties and parameters of foot finite element models in China. Vernier caliper is a common method for measuring the width and thickness of ligaments and tendons to calculate the cross-sectional area. OBJECTIVE：To design a new ligament cross-sectional area measuring instrument to improve the measurement accuracy. METHODS：The cross-sectional area of the five fresh cadaver ankle ligaments was respectively measured using the new instrument and vernier caliper, and then a comparative analysis of the two measurement methods was performend. RESULTS AND CONCLUSION：The cross-sectional area of anterior talofibular ligament, calcaneofibular ligament, tibionavicular ligament and calcaneotibial ligament was （20.61±7.52）, （22.38±11. 49）, （33.09±9.91） and （28.20±10.88） mm^2, respectively measured by the vernier caliper, and （17.59±4.03）, （20.77±7.91）, （28.08±8.14） and （30.39±7.98） mm^2 by the new ligament cross-sectional area measuring instrument. These results suggest that this new measuring instrument is accurate, reliable and easy to operate, which can be used as a special instrument to measure ligament cross-sectional area, but further studies wil be necessary.
