Intervertebral disk prosthesis system

An intervertebral disk prosthesis system for forming an artificial intervertebral disk comprising a first prosthesis component and a second prosthesis component which is independent of the first prosthesis component, wherein each of the two prosthesis components comprises a first and a second vertebral body contacting element for placement on neighboring vertebral bodies which bound an intervertebral disk space of a spinal column and a joint element that is mounted between and is moveable relative to at least one of the first and second vertebral body contacting elements, wherein each prosthesis component comprises a ball joint that is mounted in a moveable manner between the first and second vertebral body contacting elements,

• the intervertebral disk prosthesis system further comprising a guidance device for defining a superior swivel joint that is defined by both prosthesis components together for simultaneously twisting the two first vertebral body contacting elements relative to the two second vertebral body contacting elements about a common center of rotation which is located in a spatial region between central points of the two ball joints,
• the guidance device on each prosthesis component comprising a respective guidance surface for guiding a movement of the two ball joints relative to the second vertebral body contacting element, the guidance surface defining a joint plane that is inclined at an angle of inclination relative to a longitudinal axis which is oriented in the direction of the first vertebral body contacting element in a basic position and is defined by the second vertebral body contacting element, the angle of inclination of the joint plane having a value within a range of 10° to 80°.
