Relationship between the mineral content of human trabecular bone and selected parameters determined from fatigue test at stepwise-increasing amplitude

19--26

Purpose: The study aimed to investigate a relationship between the mineral content of the human trabecular bone and parameters determined from compression fatigue tests at stepwiseincreasing amplitude. Methods: Mineral content of the trabecular bone was estimated as ash density and bone mineral density values. The relationship between the ash density, bone mineral density and factors obtained from fatigue test: fatigue life, cumulative elastic energy and cumulative energy of dissipation was determined. Results: The results from the measurements of ash density and bone mineral density show good correlation with the fatigue test results. The relationship was estimated based on the correlation coefficient R within 0.74-0.79 for the particular pairs of factors. Conclusions: The study shows that the ash density and the bone mineral density are good predictors to estimate the fatigue life of trabecular bone. The study also validates the applicability of the tests at stepwise-increasing amplitude in determining the mechanical properties of trabecular bone.

Relationship between BMD, apparent and ASH dunsity of human trabecular bone

Trabecular bone is one of components of bone which quality is responsible for strength whole human bone. It is a porous structure, which change with age. In medical practise for estimation quality of bone the most often is used dual energy x-ray absorptiometry (DEXA). For scientific investigation of bones are often used apparent density and ash density. In the work presented results comparison values BMD, apparent and ash density obtained from measurement samples of human trabecular bone. Obtained values coefficient of determination R2 for relationship between this densities were in range 0,28÷0,62.
