Lin M, Shapiro SZ, Doulgeris J, et al. - A finite element analysis study was performed to explore the impact of cage-screws on the biomechanical characteristics of the human spine, implanted cage, and associate hardware by comparing the micromotion and subsidence. Researchers constructed a finite element (FE) model of a C3-C5 cervical spine with anterior cervical discectomy and fusion (ACDF). They examined three models: the first was the original spine (S1 model), the second, S2, was implanted with cages and anterior plating, and the third, S3, was implanted with a cage-screw system in addition to the anterior plate. The outcomes exhibited that the cage-screw and anterior plating combination has promising potential to decrease the risk of micromotion and subsidence of implanted cages in two or more level ACDFs.
