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.
The disc consists of two titanium alloy end plates separated by a deformable core intended to allow natural disc movements.
The ESP prosthetic disc restores the mechanical properties of the intervertebral disc and in particular, its shock-absorbing properties.
