External modular network implants - design 3 - prototype The proper shape of MAI is related to the bones microscopic structure and to the numerical simulation presented in the previous chapter. As one can observe comparing the structure of a healthy bone Fig. 58 with that of an osteoporotic bone Fig. 59 the internal architecture of the healthy bone has a regular modular structure Burstein et al. 1976 . Fig. 58. Normal bone Fig. 59. Osteoporosis affected bone Osteoporosis affect the bones net and leads to additional load. These problems increase the risks for bones fracture or they can limit the relative bones mobility Evans 1976 . A modular net identical in structure with the bone and locally configurable in terms of tension and release is best design solution in terms of biocompatibility. The identification of the mechanical solicitation of the particular bone structure using finite element method leads to the concept of the practical implementation of a feasible device able to undertake the functionality of normal bones. This device will partially discharge the .
