Considerable researchers analyzed the effects of hormone treatment on osteoporoticvertebral bones. Hormone treatment of age-related osteoporotic bone has a potential to decrease anincidence of osteoporosis. In the present paper, experimental and simulated tests for the mechanicalcharacteristics of osteoporotic models and their hormone-treated models were investigated. Threedimensional (3D) geometries of the models (rapid prototyped and finite element models) weregenerated from high resolution micro-computed tomography ($-CT, Skyscan 1076, Skyscan,Belgium) scan data for the central parts of the second lumbar vertebrae. From these 3D geometries,cubic specimens with side length 6.5mm were formed and analyzed. Rapid prototyped (RP) models,instead of the real bone specimen, of vertebral trabecular bones were created in the fused depositionmodeling (FDM) machine. In the present study, experimental compressions test for RP models werecarried out by the INSTRON testing machine (8874 series, Instron, UK). The mechanicalcharacteristics of finite element (FE) models for simulated compression tests were compared withphysical predictions from RP models for experimental compression test. As a result, it is found thatthe hormone therapy is likely to be less effective than reported by previous researchers. Aremarkable agreement was achieved between the results obtained from the experimental tests forRP models and simulated tests for FE models
