| Research Abstract |
To elucidate a mechanism of a foot disease, it is important to comprehend the load response of its complicated structure three-dimensionally. We quantitatively evaluated the bone rotation of each joint in the medial longitudinal arch(MLA)(first metatarsal bone, cuneiforms, navicular, talus, and calcaneus) and compare the load response in normal feet to that in flat feet while using the reconstructive three dimensional(3D) CT image data during weightbearing. The total relative rotations were significantly larger in the flatfoot in comparison with the healthy foot in all MLA joints, and the largest rotation was observed in the talonavicular joint, followed in order by talocalcaneal joint, tibiotalar joint, first tarsometatarsal joint, and cuneonavicular joint.
