Abstract

The invention concerns an assembly (1) comprising an interspinous wedge (5) configured to be inserted between the spinous processes (9) of two vertebrae (2) to be treated, whereof at least one zone designed to be placed between the spinous processes of the vertebrae is made of an elastically deformable material. The assembly (1) further comprises: two compressive lateral elements (6), designed to be placed on either side of the wedge (5) in the longitudinal direction, said compressive lateral elements (6) being deformable between releasing positions, wherein they are relatively spaced apart from the wedge (5) in the transverse direction, and compressive positions, wherein they are relatively close to the wedge (5) in the transverse direction; and two lateral transmission elements (7), placed between the compressive lateral elements (6) and the wedge (5), configured to press against the wedge (5) in the transverse direction thereof, at the interspinous zone (10) of the wedge (5).

Description

technical field

[0001] The present invention relates to a posterior vertebra support assembly.

[0002] In the case of degenerated intervertebral discs of two vertebrae, and / or stretched degenerated ligaments, it is known to place wedges between the spinous processes of two vertebrae to make vertebral support possible. In this respect, the French patent applications with application numbers FR 9403716 and FR 9802300 filed by the proprietor of the present application are incorporated by reference. Background technique

[0003] The wedges in these earlier patent applications are attached to the spinous processes of the two treated vertebrae by two separate ligaments, each passing through the wedge and tightly surrounding the corresponding spinous process. As the spine flexes in a forward direction, the spinous processes separate from each other, causing longitudinal stretching of the wedge.

[0004] The disadvantage of this longitudinal stretching is that the wedges are comp...
