摘要: The embodiments provide various interbody fusion spacers, or cages, for insertion between adjacent vertebrae. cages may contain an articulating joint to allow expansion and angular adjustment, enable upper lower plate components move relative one another. have a first, configuration characterized by reduced size at each of their ends facilitate through narrow access passage into the intervertebral space. In second, expanded configuration, are able maintain proper disc height stabilize spine restoring sagittal balance alignment. adjust angle lordosis, can accommodate larger lodortic angles in configuration. Further, these promote further enhance stability immobilizing vertebral bodies.
