Fracture prediction on patient-specific tibia model with osteogenesis Imperfecta under various loading direction
This study aims to predict the fracture of bone with osteogenesis imperfecta (OI) by considering the homogenization properties of real patient. A Type-III of osteotomy in OI femur was used as bone specimen. Nine representative volume element (RVE) models were developed based on μCT-images of bone...

| Summary: | This study aims to predict the fracture of bone with osteogenesis imperfecta (OI) by
considering the homogenization properties of real patient. A Type-III of osteotomy in OI femur
was used as bone specimen. Nine representative volume element (RVE) models were
developed based on μCT-images of bone specimen. Homogenized properties particularly the
Young's moduli of the RVEs was obtained based on homogenization theory in Voxelcon
software. The obtained homogenized properties were then assigned to the OI patient-specific
model that was developed from CT-images of real patient. The fracture of OI bone was
predicted based on linear static analysis and finite element method under loadings of activity
daily living (ADL). The results found that the fracture might be happen to the patient under
jumping load case, whereas the subject is expected to be safe under standing still and walking
load case. |
