Biomechanical consideration regarding bone substitutes use in surgical treatment of chronic osteomyelitis

The main aim of this study is to present the use of bone substitutes in chronic ostheomielitis surgical treatment and its biomechanical influence. MATERIAL AND METHODS: First step is three-dimensional reconstruction to one femur using CT sections; the second is the reconstruction of infected bone volume, synthesis of material properties, synthesis of loading forces, synthesis of boundary condition and, finally, finite element analysis. RESULTS: The calculated Von Mises stress as a result of finite element analysis indicates that bone substitute implantation lead to a stress distribution in bone similar with a health femur.
