Abstract
A guidance device including two vertebral units adapted to be fixed to the posterior side of two adjacent vertebrae of the spine and wherein the two units have substantially spherical complementary articulation surfaces which, when the units are fixed to the vertebrae, extend overall on the posterior side of the vertebrae and slide against one another about a center point located in the intervertebral space that separates the vertebrae, and wherein the device also includes a mechanical element to limit an amplitude of the relative sliding of the articulation surfaces.
