EXPERIMENTAL DETERMINATION OF MECHANICAL PROPERTIES OF BONE

Abstract

The annual increasing number of hip fracture due to osteoporosis and other bone diseases has been announced as a major public health problem. A total of 1.5 million fractures occur every year, including 500,000 vertebral fractures and 280,000 hip fractures. This prognosis points out the importance of preventing and reducing osteoporotic fractures. It is therefore important to detect the disease in time and before the occurrence of the first fracture leading to postoperative complications. For this reason, femoral fractures caused by the osteoporosis becomes increasingly important goal for both clinicians and biomedical researchers in order to evaluate and to prevent the risk of neck femur fracture with suggestion of the required necessary treatments. Over the past decades, a number of different Finite Element (FE) models were developed to predict the femur fractures. One of the main steps is to feed the mechanical properties of bone to these models. This can lead us to the first objective of this work which aims to alert primarily to the importance and seriousness of fractures resulting from osteoporosis. Second, to prepare a practical procedure to: (i) prepare bovine bone samples and to (ii) conduct tests on bone materials. Series of test results resulting was conducted and mechanical elastic modulus, shear modulus and properties of bovine cortical bone were determined.
