Fidji® Lumbar Cages
PEEK
![]() PEEK interbody fusion cages are more than simple spacers permitting vascularization between vertebral endplates; they mediate the application of physiological load conditions to the bone graft. This ensures continuity in the mechanical properties throughout the level involved, and consequently optimizes the conditions contributing to successful fusion. |
