Estimation of the pre-deformed ankle bones shapes are a key factor in artificial joint replacement surgery, and the surgeon can achieve highly satisfactory outcomes for patients such as less pain and sufficient function with an alternative ankle joint. However, the relationship between the bone shape deformation process and stage of the disease remains unclear. In this study, we investigated the relationship between the disease stage and three-dimensional rear foot bones (tibia, talus, and calcaneus) in patients with ankle OA. Methods: Thirteen joints of eight women (69 ± 2 years) with OA and five healthy joints of five women (69 ± 2 years) with traumatic foot injury were investigated in this study. The images of the foot were captured using a Computed Tomography (CT) scanner, with the three-dimensional bone model created by stacking the CT images. In the control group, one left foot was randomly selected as the reference model. A three-dimensional cubic lattice deformation field was calculated from the three-dimensional bone model using the volume registration method to quantify the three-dimensional differences between the patients/subjects and the reference model. The relationship between the stage and shape was analyzed using principal component analysis (PCA). Results: In the tibia, the value of the first principal component corresponded to the curvature radius of the canopy surface shape, with a significant increase (p < 0.05) in the curvature radius of the tibia canopy surface in OA compared with the control group. In the talus, the value of the first principal component corresponded to the curvature radius of the subtalar joint surface, with a significant difference observed between the control and OA groups. The curvature radius of the subtalar joint surface tended to be larger in the OA group than in the control group. Conclusion: Three-dimensional analysis using PCA revealed that the curvature radius of the tibia canopy surface increased in the OA group, similar to that observed in two-dimensional X-ray analysis. Furthermore, the proposed method revealed bones shapes deformation in the subtalar and ankle joints along three dimensions in the OA stage. Thus, the shape change of the tibia and talus could be evaluated three-dimensionally and quantitatively for each stage using the proposed method.","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"ClinMed International Library"}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.23937/2643-3885/1710043","subitem_relation_type_select":"DOI"}}]},"item_10001_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"copyright 2020 ClinMed International Library.
