In total, 61 samples were collected from human trabecular bone after hip arthroplasty. Samples were examined on microCT device. As the result, values of four structural indices (BV/TV, Tb.Th, Tb.N and BS/BV) describing the structure of trabecular bone were obtained. The fatigue tests of the samples were carried out with stepwise increasing amplitude. From the test obtained fatigue life Ns was found between 3,75·103 cycles and 5,02·104 cycles. Relations between fatigue life and structure indices were described by determination coefficient R2. Values of the coefficient were found in range 0,49-0,69. On the base of the obtained results we ascertained existing relation between selected structure indices and fatigue life obtained from test with stepwise increasing amplitude.
