Abstract:
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) mm2, respectively measured by the vernier caliper, and (17.59±4.03), (20.77±7.91), (28.08±8.14) and (30.39±7.98) mm2 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.
