Abstract: The invention relates to an adhesive, shock-absorbing prosthesis (1) comprising two perfectly-integrated means, namely: a homogeneous block (11) which is made from a flexible, shock-absorbing material that is resistant to compression pressures, i.e. a polyurethane-type material that can withstand the repeated mechanical stresses of the intervertebral disk; and at least one adhesion means (12 or 13) which is used to provide suction such that the prosthesis (1) can be fixed in a flexible manner.

Abstract: A flexible intervertebral linking device (1) is provided. The device (1) utilizes two sets of structures. A first structure (11) is a rigid structure (110, 112, 114, 116) preferably made of biocompatible metallic materials providing the device with good mechanical resistance by integral load transmission without deformation. A second structure (12) is a flexible or damping structure (121 and 122) 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.

Abstract: The invention concerns a distraction device (4) for controlling the development of the deformation of a child's trunk during growth easily implantable into the human body and comprising rods (35, 36) coupled to the bones and mounted on central adjusting means (300) provided with a small hole (312) for engaging a small tool designed to adjust the distance separating the bone coupling means, said device (4) including a miniature casing (410) enabling the rods (35 and 36) to be translated in the direction of growth via a toothed wheel (311), said means being combined with an assembly of means: non-return catch (37), elastomer block (373), rigid cage (374) which enable the device (4) to be disengaged, tensioned and locked in one direction, while allowing growth to be monitored.

Abstract: A device (3) used to fit a nucleus prosthesis made up of: a deformable elastic nucleus prosthesis (1) which can adapt to the shape of intervertebral cavities, the prosthesis consisting of two parts, namely a male part (11) and a female part (12); and an insertion assembly (2) which is connected to the nucleus prosthesis (1). The elastic deformation of the nucleus prosthesis (1) makes it possible for the prosthesis to be inserted into the intervertebral cavity. The prosthesis is inserted using the elasticity thereof and the insertion means (2) which form part of the device (3) before insertion, but which can be subsequently removed.

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.

Abstract: 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.
