Modern artificial disc replacement devices are precision-engineered medical prosthetics developed to replicate the exact kinematic parameters of healthy human discs. Rather than relying on bone bridging across a joint, ADR relies on osseointegration, where bone grows directly into porous titanium or plasma-sprayed endplates, while a mobile or fixed core provides controlled articulation.
