The ESP prosthetic disc is the result of 10 years of collaborative research work at the Hôpital Pitié Salpêtrière in Paris, the French Atomic Energy Commission (CEA) and the Université Paris VI, and was driven by the Oséo Innovation contest in France.
It consists of two titanium alloy plates and an elastomer pad. The pins on the outer surfaces of the plates facilitate primary fixation.
The ESP prosthetic disc restores the mechanical properties of the intervertebral disc and in particular its damping properties
