ONZ neurosurgeon Dr. Thomas Bierstedt about ESP disc.
The ESP disc prosthesis is made of 2 titanium alloy end-plates and an elastomeric cushion. The spikes on the end-plates outer surfaces improve primary fixation. The combination of a hydroxyapatite (HA) coating on top of a T40 rough surface are considered as one of the best existing coating. The titanium alloy used for the end plates allows clear medical imaging and guarantees good bony fixation over time.

ONZ neurosurgeon Dr. Bernd Illerhaus about Synergy.
The Synergy Disc is our viable alternative to fusion in patients with pre-operative alignment issues. It is available in many different sizes and configurations. It is our preferred implant type in case of kyphotic misalignments and by this restoring sagittal balance and preserving vertebral motion.
Different anatomies require different implant solutions. Principally we target to replace the pathomorphologic disc by an artificial disc that mimics the biostatical features of a natural, healthy disc. In patients with very low discal heights we have to react with the smallest implant types available.
