Abstract

Osteoporosis is a disease characterised by reduction of Bone Mineral Density (BMD) and micro-architectural deterioration of bone tissue. From all the osteoporotic fractures, hip fractures are the ones with most serious consequences. A new treatment to prevent these fractures is femoroplasty, consisting of the injection of bone cement into an osteoporotic femur in order to improve its mechanical properties. Injecting large amounts of cement can lead to bone thermal necrosis or create regions of stress concentration. The present study introduces a new evolutionary method for the optimization of the injected bone cement distribution and the minimization of its volume. The new method was numerically applied in a typical case of an osteoporotic femoral augmentation and compared to a powerful deterministic optimization method.
