概要 |
The risk of hip fractures in osteoarthritis patients has increased due to bone structure deterioration and increased incidental falls. This study aimed to determine the strength and fracture location ...of the normal and osteoarthritis femurs. The quantitative computed tomography (QCT) based finite element method (FEM) was used for the analysis. Three-dimensional models were constructed and simulated through Mechanical Finder. Bone mineral density (BMD) was estimated and considered as one of bone material properties index. Young’s modulus (E) and strain energy density (SED) distribution were also investigated. A strong correlation between strength and average BMD was observed in normal femurs. In the osteoarthritis femur, the fracture may occur in both the head and neck region, whereas the neck region is mostly fractured in normal femurs. The average femoral strength of the normal femurs was found to be approximately 3957±293 N, while 3549±180 N is for that of osteoarthritic ones.続きを見る
