The aim of ROTAIO is to replicate the natural movement of a healthy disc. The solution: a variable centre of rotation, enabling physiological facet-guided movement. However complex the joint kinematics of ROTAIO, the surgical technique nevertheless remains simple. ROTAIO is implanted by the ‘gold-standard’ Smith-Robinson technique as a single component without additional preparative surgical steps. ROTAIO can therefore be described in a single phrase: Implantable like a cage –moves like a disc.

  • Posteriorly-oriented prosthesis design.

  • Variable centre of rotation.

  • Pure translation, uncoupled from rotation.

  • Pre-mounted, sterile packed.

  • Proven surface teeth fixation.

  • Extensive mechanical testing.
