Posterior vertebral support assembly

The invention relates to a that is inserted to the treated two vertebra (2) and spine-shaped (9) are interspinal wedge-shaped block (5), at least designed is located by the material of elastically deformable is made of vertebra's a area between spine-shaped treatment. Module (1) further - comprising: And two side parts (6), is designed along the longitudinal placing a wedge-shaped block (5) are respectively; the compression side part (6) deformable between the release position and pressurizing positions; the release position; the compression side part (5)) is arranged along the transverse and wedge-shaped block relatively, wherein a pressurizing position; the compression side part of the relatively close to the wedge-shaped block (5); Two lateral transmission part (7), is placed in the pressurizing side part (6) with a wedge-shaped block (5), wherein; a wedge-shaped block (5) interspinal area (10) is transverse face of the wedge-shaped block (5) is.
