MRI compatible The titanium plates reduce artifacts under the MRI and improve the postoperative control. The plates are coated with DIAMOLITH®. Shock absorption The shape of the inferior plate and the PE nucleus are designed to enable absorption of shocks and vibrations. Mobile or fixed nucleus The BAGUERA®L concept allows the surgeon to choose the mobility of the nucleus intraoperatively, without changing the superior or inferior plates. The movement of the mobile nucleus is controlled to respect rotation movements. Primary stability The porous titanium coating as well as the 5 upper and 5 lower fins are designed for primary and secondary stability.
