The invention relates to a dynamic cervical disk prosthesis () comprising two upper () and lower () rigid plates containing a viscoelastic element (), said upper and lower plates (and) having a slightly cambered and striated contact face, the main characteristic of this invention being that the lower plate () is in the form of a housing, compatible with a twist-lock of the upper plate () while allowing the mobility and damping of the two plates (and) around the viscoelastic element () that can be freely distorted thereby avoiding all risk of detachment of the prosthesis when subjected to applied forces.

Dynamic cervical disk prosthesis provided with damping

A dynamic intervertebral stabilization device () comprising the following elements:

Dynamic intervertebral stabilisation device

Adjustable base piece () that can be incorporated into a prosthesis replacing the corpus vertebrae and comprising&#x2014;a plate () positioned in contact with an internal face of the adjacent corpus vertebrae; &#x2014;a curved panel () that can be adjusted in multiple directions by virtue of a ball stem () housed in a head () of the plate () which allows it to adopt the optimal angle with respect to this fixed plate (), so that the said curved panel (), thanks to its possibilities of multi-axis adjustment, can press espousing the external shape of the corpus vertebrae adjacent to the prosthesis, &#x2014;a clamping plug () which, once tightened, fixes the panel () to the plate () in the desired position, thus allowing this adjustable base piece () to be simultaneously in contact with an internal surface of the adjacent corpus vertebrae, thus giving this base piece, once attached to the corpus vertebrae, great bearing stability, with good adaptation to suit all shapes of vertebra encountered in real life.

Base piece adjustable prior to attachment and easily incorporated into a vertebral replacement device

The a device is provided for dynamic posterior stabilization. The device combines includes a mobile piston rod with a piston head at an end thereof; a viscoelastic shock-absorbing unit having a convex surface; a fixed rod defining an angle relative to an axis of a casing and the fixed rod including, at an end thereof, a concave surface; a viscoelastic ring; and wherein the viscoelastic components are contained within the casing.

Device for dynamic posterior stabilisation matching the anatomic lordosis

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. Said system his intended to be used in order to straighten and support a child's torso and his/her vertebral column, by acting on the central means by tightening the screws; dampen dynamic loads; be adjustable according to growth, the system being re-adjusted as often as necessary; and prevent significant stresses from being created in the bones, in particular, at the hooks, without impeding growth.

Distraction and damping system which can be adjusted as the vertebral column grows

A flexible intervertebral linking device () is provided. The device () utilizes two sets of structures. A first structure () is a rigid structure () preferably made of biocompatible metallic materials providing the device with good mechanical resistance by integral load transmission without deformation. A second structure () is a flexible or damping structure (and) made of biocompatible viscoelastic materials, permitting repeated elastic deformations. The combination of the two structures providing the device with both resistance and mechanical dampening of forces to which it is subjected, with the purpose of compensating for any deficiency in the flexibility of certain anatomical links of the human body.

A distraction device enabling management of the evolving deformation of the trunk of a child during growth. The device is easy to implant on account of its compact shape and includes two rods which can be bent and deformed on the ends thereof and which are mounted on a central adjusting member which is provided with a small hole for engaging a small tool that is designed to adjust the distance separating the elements for attachment to the bone. The inventive device can be locked in a position which is determined by the tightening of two screws which are disposed on the adjusting device.
