The paper discusses the results of measurement of elastic modulus and the mineral content for 42 samples of trabecular bone, collected from femoral heads after alloplastic implantation of hip joint. The samples were collected from femoral heads with coxarthrosis and osteoporosis. Measurement of elastic modulus in compression test, and with the use of ultrasonograph technique with 0.5, 1 and 2 MHz frequency of transducers was performed for the samples. Also, evaluation of mineral density of the bone - BMD, and ash density - Ash.D was performed. The results obtained suggested usability of BMD and Ash.D indicators for assessment of elastic properties of trabecular bone. The relations with elastic modulus evaluated using R correlation coefficient were similar for BMD and Ash.D, and contained within the range R = 0.57 – 0.68.
