The paper presents results of static and fatigue strength, and mineral content for 60 trabecular bone samples. The samples were collected from human femoral heads after alloplastic treatment of femoral head, of patients suffering from coxarthrosis and osteoporosis. Evaluation of mineral density of the bone BMD, and ash density - Ash.D were performed. Static and fatigue strength of the bones was determined through compression test. Fatigue compression test was performed with stepwise increasing amplitude. The results obtained suggested correlation between BMD, Ash. D and the results of static and fatigue test. The relations obtained, evaluated using R correlation coefficient, fell within the range R = 0.70 – 0.75. The results confirmed the usability of BMD and Ash.D indicators for evaluating static and fatigue strength of trabecular bone.
