In one embodiment, the implant may include a jack base, a jacking segment and a compressible spacer or sleeve. The implant may be inserted through a single stab or puncture entry. Jack base is placed in a first portion of a vertebra via a hole in an adjacent vertebra, in one embodiment, and the jacking segment is placed in the adjacent vertebra and connected to the base. After being connected, the depth of the adjustable portion of jacking segment in its vertebra determines the spacing between portions of the adjacent vertebrae. |
