Claim:
1. An intervertebral expansible implant, comprising: a plane of expansion intrinsic to the implant, wherein the implant includes a first length corresponding to a contracted configuration and a second length shorter than the first length corresponding to an expanded configuration; first and second opposed plates wherein each plate includes a recess configured for engaging a portion of a respective vertebrae of two vertebrae adjacent each respective plate during use of the implant, wherein the first and second plates are intended to move away from one another according to the plane of expansion as the implant is expanded; at least first and second implant end members monolithically integral with each of the opposed plates, wherein the opposed plates move away from one another as the end members are brought towards one another; at least a first support and a second support, wherein each support is connected to respective first or second end members, and is disposed between the respective first or second end members and the first or second opposed plates, wherein each support is separated from a winged portion of at least one of the first and second opposed plates by a transverse slot extending over a length of each support; and a retaining element configured to be retained by the implant after expansion to retain the implant, once expanded, in the expanded configuration, wherein: the head-recess is sized to receive and retain the head portion of the retaining element, such that when the head portion of the retaining element is fully received into the head-recess, a top surface of the head portion sits flush with or below the end-surface.
