In osteoporosis researchs, animal models have been used widely, but every model have associated with some advantages and disadvantages. In vitro studies with fresh cadaver look like good solution, however paucity of cadaver restricts its use. Demineralized calf vertebra model have been introduced as a new option. The aim of present study to check this new model on histopathological view and bone mineral density changes. Lumbar spines of seven fresh calves were cleaned from soft tissues and were submitted to DXA exams which provide the areal bone mineral density (BMD ) and bone mineral contents ( BMC ). Than, demineralization procedure was done for each L1 and L5 vertebras of calves whereas other vertebras were used as control group. Following procedure, new DEXA exams were made. Light microscobic evaluation with Hematoxylen-Eosine staining was achieved in control and study groups. As a result, bone mineral density changes was statistically significant between two group, but histological appearance was far from ordinary bone with empty bone lacunes in demineralized vertebras.
