Finite element analysis of different spinal cage designs for posterior lumbar interbody fusion

The study on spinal cage designs for their implementation in the medical field is developing over the years. Currently, many designs have been studied varying from the biomaterials and the designs. This study aimed to determine the best design structure of an annealed titanium spinal cage with the i...
