Abstract
In an intervertebral implant with a top contacting element, a bottom contacting element and arranged between these a core which with an upper, spherical bearing surface engages a spherical bearing socket, having the same radius, of the top contacting element and with a lower, spherical bearing surface engages a spherical bearing socket, having the same radius, of the bottom contacting element, in order to improve the kinematics and the endurance, it is proposed that the radius of the bearing surface and of the bearing socket receiving it differ on opposing sides of the core at least by the factor 5.
