Abstract
An intervertebral implant comprising a spacer for engaging between two spinous processes of two vertebrae of the spine. The spacer has two elements each presenting a first part suitable for being connected to a spinous process and bearing second parts opposite from the first part, the bearing second parts being situated facing each other. An elastically-compressible member is disposed between the bearing second parts. Links are provided which are distinct from the elastically-compressible member for linking together the two elements, the link member being suitable for blocking translation movement of the two elements relative to each other when the two elements are driven apart from each other.
