    The presented study aimed to examine the compressive and tensile behavior of the polyurethane foams mimicking trabecular tissue in the artificial human femurs and assess their potential to replicate osteoporotic type of human bone tissue. Two types of Synbone femur models: one of the normal density (model 2350) and one of the lower density (model LD2350), and three types of Sawbones femur models (model 1130-21-8, 1130-21-3, 1130-192) were investigated. Polyurethane foams were extracted in the form of slices cut in coronal plane from the femoral head. Cuboid samples were cut in three different directions and tested uniaxial for identification of compressive and tensile properties including elastic modulus, Poisson’s ratio, yield limit, and ultimate strength. The ANOVA test revealed that only SYNBONE LD2350 trabecular tissue exhibits anisotropy properties (p<0.001). In most cases, the tensile properties were greater than compressive ones (t-test, p<0.001). The obtained results are within the ranges suggested by other authors for mimicking the osteoporotic type of human tissue. The presented data broadens the range of data on mechanical properties provided by the producers. These data can serve as a reference for researches using composite femurs made of these particular polyurethane foams for conducting biomechanical studies and validation of accompanying numerical simulations.
