Guided mobile nucleus The guided mobile PE nucleus is designed to prevent excessive constraints on the facet joints. It allows 6 degrees of freedom. Anatomical DESIGN The sloping anatomical design of the plates optimizes the fit between the device and the disc space, and maximizes the endplate coverage. MRI compatible The DIAMOLITH® coated titanium plates reduce artifacts under MRI for a better postoperative control. Radiolucent holder The radiolucent holder allows for both the verification of the anterior position of the device and confirmation of the fitting accuracy. Thanks to this holder, the device is delivered pre-assembled for better handling.
