The distal tarsal group includes the navicular bone, three cuneiform bones and the cuboid bone. A portion of the navicular bone, the navicular prominence, projects on the medial side of the middle of the foot, inferior and anterior to the medial malleolus. Distal to the navicular, the three cuneiform bones—medial cuneiform, intermediate (middle) cuneiform, and lateral cuneiform—line up across the foot. These bones, plus the more lateral cuboid bone, connect the calcaneus and talus to the metatarsal bones.

The finite-element foot model was constructed based on the computed tomography (CT) image of a foot, as shown in Figure 2(a), using Hypermesh 2019 (Altair Engineering Co.). Materialise Mimics (Materialise Co.) was used to construct the finite-element model of the fifth metatarsal with distributed material properties. The bone structure consisted of the basal bone, metatarsal bones, medial cuneiform bone, intermediate cuneiform bone, lateral cuneiform bone, and cuboid bone. The talus—calcaneus–scaphoid bone and proximal phalanx—intermediate phalanx—distal phalanx of each toe were integrated as rigid bodies. Beam elements were used to model the ligaments, tendons, and aponeuroses. Second order tetrahedral solid elements were used for the bones and soft-tissue modelling. The total number of finite elements was 199 634.
