Posterior vertebral support assembly to correct for vertebral disk degeneration, includes two lateral transmission elements placed between two lateral compression lines and a spacer for maintaining height of inter-spinal zone

摘要

The support assembly includes two lateral compression lines (6) interconnecting two adjacent vertebrae (2) and being elastically deformable in a longitudinal direction. A spacer (5) is placed between spinal apophyses (9) of the two vertebrae. The lateral compression lines are deformable between a relaxed condition when the spine is extended in a curved position, and a compression condition when the spine is in flexion. Two lateral transmission elements (7) are placed between the compression lines and spacer so that when they are in their compression position they support the spacer in a transverse sense.
