Every prosthesis is mobile. 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. This ensures that the emphasis is not merely on maintaining movement, but in particular on the quality of movement of a natural disc. 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.
Maintaining physiological movement
- Posteriorly oriented prosthesis design
- Perfect adaptation to the natural anatomy
- Variable centre of rotation
- Corresponds to the centre of rotation of a healthy disc
- Pure translation, uncoupled from rotation
- Promotes facet-guided motion, no gaping of the joints
Standard surgical technique
- One-piece prosthesis design
- Similar to a cage implantation
- Pre-mounted, sterile packed
- No assembly required – ready for immediate use
- Proven surface teeth fixation
- High primary stability without keel preparation
Safety-first implant design
- Posteriorly oriented centre of rotation
- Implant positioned in front of the posterior edge
- Instruments with depth stops
- Guarantee simple, safe manipulation
- Extensive mechanical testing
- Giving your patient safe segemental movement – for life
