Abstract
The invention relates to a dynamic cervical disk prosthesis () comprising two upper () and lower () rigid plates containing a viscoelastic element (), said upper and lower plates (and) having a slightly cambered and striated contact face, the main characteristic of this invention being that the lower plate () is in the form of a housing, compatible with a twist-lock of the upper plate () while allowing the mobility and damping of the two plates (and) around the viscoelastic element () that can be freely distorted thereby avoiding all risk of detachment of the prosthesis when subjected to applied forces.
