Abstract: The implant includes two side walls resting against the vertebral end-plates and an intermediate wall joining the supporting walls. The implant can be deformed for insertion between the vertebrae to be treated to restore the attenuated mobility of the vertebrae, and includes mounting elements mounting on the vertebrae. The side walls have a curved shape, whose convexity is oriented towards the outside of the implant; the intermediate wall has a curved shape, whose convexity is oriented towards the outside of the implant such that it does not form any pronounced angles with the supporting side walls. The supporting side walls and the intermediate wall, have a partially oval shape; and the mounting elements are configured such that the implant can be mounted on the vertebrae.

Abstract: The present invention provides interspinous vertebral and lumbosacral stabilization devices, and methods of using these devices for treating spinal instability conditions. The invention includes interspinous vertebral stabilization devices adapted for placement between the spinous processes of two or more adjacent vertebrae. The invention also includes lumbar stabilization devices adapted to be placed between a lumbar vertebra and an adjacent vertebra, including the first sacral vertebra (S1), to stabilize the lumbosacral region of a patient, and method for using such devices.

Abstract: The invention related to a distraction and damping system which combines two devices, namely a first distractor device and one or more other damping devices. The aforementioned distractor device is for children's bones and can support and lengthen said bones by means of rods which are mounted to an adjustment means. Moreover, said distraction and damping system is hooked to the bones at the ends of the rods which are connected to hooks. The above-mentioned damping devices consist of flexible and rigid means. The inventive system, which results from the combination of said two devices, comprises the implantation of novel means such as serrated rods, one of the ends of which takes the form of a piston head.
