Biomechanical analysis of stand-alone lumbar interbody cages versus 360° constructs: an in vitro and finite element investigation
Autor: Ali, Kiapour, Elie, Massaad, Amin, Joukar, Muhamed, Hadzipasic, Ganesh M, Shankar, Vijay K, Goel, John H, Shin
Publikováno v: Journal of Neurosurgery: Spine. 36:928-936
OBJECTIVE Low fusion rates and cage subsidence are limitations of lumbar fixation with stand-alone interbody cages. Various approaches to interbody cage placement exist, yet the need for supplemental posterior fixation is not clear from clinical stud
