Description
Osteoporosis, characterized by low bone density and deterioration, poses significant fracture risks, typically in older adults but also affecting children. Pediatric osteoporosis is a serious concern, requiring unique approaches distinct from adult treatments. This study addresses the gap in finite element analysis (FEA) models for pediatric bones by developing and validating a detailed model of the pediatric femur for children under 12 years old. Using scaled models to represent pediatric bones, this research demonstrates the unique biomechanical properties and fracture risks in children. The findings reveal that 2-year-old children's bones, with a higher density of 237.5 kg/m³ and a Young's modulus of 8.67 GPa, exhibit better stress management, resulting in lower deformation (8.31 mm) and von Mises stress (53.96 MPa), compared to 11-month-old bones. The results align closely with published data, with less than a 6% variance, highlighting FEA's accuracy in predicting stress patterns. The study concludes that pediatric osteoporosis significantly increases fracture risk, emphasizing the need for early detection and tailored treatment strategies.
