INTEGRATED GLOBAL LAYOUT AND LOCAL MICROSTRUCTURE TOPOLOGY OPTIMIZATION APPROACH FOR SPINAL CAGE DESIGN AND FABRICATION

摘要

A method being in block (10) where a mechanical environment of a lumbar spine segments is modeled. In block (12) the method perform a global layout topology optimization process. Then in Block (14), the method performs density distribution on the global layout topology optimization solution from block (12). The density distribution contemplates a local microstructure topology optimization solution from block (16). After completion of the density distribution process in block (14) , the methods proceeds to block (18). In block 18, the methods provides an integrated design topology solution for the fusion cage. In the block (20), the as-designed cage fabricated.
