This study investigates the biomechanical behavior of cancellous bone in the os occipitale through finite element modeling.Utilizing micro-computed tomography scans, 47 bone segments were analyzed, and their apparent Young's moduli of each segment were determined in three orthogonal directions.The results revealed strong directional dependencies of Young's modulus on bone volume fractions.In contrast, nondirectional dependency exhibited a weaker correlation, indicating an orthotropic elasticity.The derived correlation equations offer an efficient means to describe cancellous bone in cranial biomechanical simulations, especially when a detailed trabecular representation is impractical.
