Fig. 3From: Preliminary exploration of the biomechanical properties of three novel cervical porous fusion cages using a finite element studyEstablish the finite element model of ACDF operation. The flow chart shows the topology optimization of the macro-structure and the parameter design of the cage frame according to the load-bearing results of the high-density fusion cage. Three kinds of porous cervical cages were obtained by filling the frame with different types of latticesBack to article page
