Cervical disc prosthesis

Combining Cervical Alignment & Balance with Natural Motion Maintains natural motion Restores sagittal alignment with unique lordotic core Achieves balance in single or multi-level procedures Reduces focal deformities The design innovations in the Synergy Disc provides a physiologic, dynamic center of rotation (COR) in flexion and extension, as well as lateral bending and axial rotation. The Synergy Disc design offers clinical benefits over existing total disc replacement devices with additional features that include the following. Unique, lordotic core geometry Low-profile disc heights Multiple, anatomic footprints Semi-constrained design with safety stops Stability zone that provides balance MRI imaging friendly Time-tested orthopedic materials The simple surgical steps with a secure fixation method provides predictable, reproducible and reliable results. Synergy Disc Design Rationale The Synergy Disc introduces deformity correction while maintaining a full range motion (ROM). It has titanium-on-polyethylene articulation with a mobile center of rotation (COR). The polythene core incorporates varying degrees of lordotic correction, to preserve or reconstruct sagittal alignment. Flexion-Extension The Synergy Disc provides 22˚ range of motion in flexion-extension Lateral Bending +/-12˚lateral bending Axial Rotation +/-12˚ axial rotation A-P Translation 2mm of pure Anterior-Posterior Translation with safety stops at the extents of motion.
