In order to apply various material properties of the spine(T12), the functional relation between the well known apparent density and HU(Hounsfield unit) from CT image were employed and thus real material properties can be assigned to each element of FE model. The FE analysis showed similar results with the experiments. With this approach accurate analysis of the vertebroplasty and its clinical applications can be expected. 한국정밀공학회 골밀도를 고려한 척추 성형술의 생체역학적 평가 Biomechanical evaluation of the vertebroplasty based on bone density Article 2 한국정밀공학회지, v.23, no.8, pp.185 - 194 한국정밀공학회지 23 8 185 194 kci ART001097905 Vertebroplasty(척추성형술) Osteoporosis(골다공증) Biomechanical study(생체역학적 연구) Finite elememt analysis(유한요소해석) PMMA(폴리메틸메타크릴레이트) Compression fracture(압박골절) Material properties(재료물성치) Vertebroplasty(척추성형술) Osteoporosis(골다공증) Biomechanical study(생체역학적 연구) Finite elememt analysis(유한요소해석) PMMA(폴리메틸메타크릴레이트) Compression fracture(압박골절) Material properties(재료물성치)
