Core Tip
Core tip: Although all artificial discs are intended to achieve the same aims, there is considerable heterogeneity in the design of lumbar and cervical implants. The “second generation total disc replacements” are non-articulating viscoelastic implants aiming at the reconstruction of physiologic levels of shock absorption and flexural stiffness. This review aims to give an overview of the available implants. We herein discuss the new challenges concerning the choice of materials, the connection between the components of the internal structure and the metal endplates and even the bone anchoring mode. We discuss the consequences of the different technological choices and we emphasize the special features to watch out for when monitoring these implants in the future.
