초록
본 논문에서는 유한요소해석을 이용하여 경골 골절부의 변형률 분포를 계산하였다. 16주에 걸친 골절 회복기간 동안 최적의 가골 형성의 조건을 찾기 위해 스테인리스 강 고정판과 다양한 적층순서를 가지는 복합재료 고정판이 고려되었다. 이 연구를 통해 골절부 가골 형성을 촉진하는 2~10% 변형률을 유발하는 최적 하중 조건을 계산하였다. 해석결과로부터 복합재료 고정판의 경우 최적의 변형률을 가지게 하는 하중조건은 스테인리스 강 고정판의 경우보다 낮았으며, 응력방패 현상을 감소시켜 골절치료에 유리함을 가지는 것을 알 수 있었다.
Abstract
In this paper, finite element analyses were used to estimate the strain distribution at the fracture site of a tibia bone. A stainless steel bone plate and various composite bone plates were considered to find out the best conditions for callus generation while bone fracture was cured for 16 weeks. Through this research, the appropriate load condition which makes the strains between the appropriate range(2~10%) was sought. From this analysis, it was found that lower level of external load is needed for the appropriate strain for the case of composite bone plate application and it was also found that the composite bone plate had potential advantages for effective bone fracture healing relieved stress shielding effect.
