Foot Transverse Arch Instability following Sequential Ligament Sectioning between the first Cuneiform and the second Metatarsal ￡
Foot Arches play important roles in weight bearingand propulsion. However biomechanics of human foot transversearch is far from being well understood and controversies stillexist. In this paper six fresh-frozen cadaveric feet were loadedfrom 0N to 1200N with 200N intervals, following sequentialsectioning ligaments between the first cuneiform and the secondmetatarsal from dorsal to plantar. Physical informations of foottransverse arch, i.e. bone displacement, bone surface strain andplantar pressure were gathered and then analyzed. The resultspresented a multi-field look into the stability of human foottransverse arch contributed by the three ligaments and disclosedinterosseous ligament, i.e. Lisfanc ligament, paid moreimportance to foot transverse arch stability than the other two.This research aimed at fostering well understanding ofbiomechanics of foot transverse arch and promoting furtherfundamental biomechanical research relating to low energyligamentous injuries in midfoot.
