20090216277 | POSTERIOR LUMBAR JOINT PROSTHESIS - There is provided a posterior lumbar joint prosthesis which includes prosthetic elements reproducing the movements of the joint facets and vertebral anchors which adapt to the variations in the anatomy of vertebra. In use, the prosthesis has lower and upper connectors on each side of the lumbar vertebra. The lower connectors are coupled with, and pivotably mounted onto, respective lower pedicular screws, and a member defining a member axis links lower and upper connectors on each side of the lumbar vertebra. Upon lateral flexion of one of the upper and lower vertebrae relative to the other, each lower connector is capable of multiaxis pivotable movement relative to the respective lower pedicular screws such that each member is capable to pivot with respect to (i) the axis of the lower screw, (ii) a first axis intersecting the lower screw and the lower connector, and/or (iii) an axis intersecting the above first axis and the lower screw, while the member can also move along the member axis. | 08-27-2009 |
20090254186 | NUCLEAR IMPLANT - The nuclear implant according to this invention constitutes, between two overlying and underlying vertebrae Va, Vb of a spine segment Sr, an intervertebral support device that damps shock and ensures the mobility of the functional unit that is formed by the vertebrae of a vertebral column, whereby the nuclear implant includes a filling element ( | 10-08-2009 |
20100145663 | METHOD FOR SIMULATING THE BEHAVIOR OF AN ARTICULATED SET OF BONES - A method of simulating the behavior of an articulated set of bone parts, in particular the vertebral column of a subject comprising a construction step of constructing a three-dimensional geometrical model of the set from data that is specific to the subject in a reference position; and a mechanical customization step of customizing the geometrical model by detailing at least some of the connection areas of the bone parts. The mechanical customization step includes a stage of customizing critical connection areas for the bone parts, referred to as junction areas; a data acquisition stage of acquiring data concerning the articulated bone set of the subject during at least one clinical test of posture in a position different from the reference position or a clinical test of movement starting from said reference position; and a characterization stage for characterizing the mechanical parameters of said junction areas in order to cause the model to reproduce the data acquired during the above-mentioned clinical test. | 06-10-2010 |
20120277862 | NUCLEAR IMPLANT - A process for nucleotomy of an intervertebral disk to create a nuclear space and a method for replacing a nucleus pulposus of an intervertebral disk after a nucleotomy are provided. The methods position a nuclear implant between two overlying and underlying vertebrae of a spine segment in the form of one or more continuous wire arranged as a stack of helices inside the nuclear space. | 11-01-2012 |
20130013006 | Intervertebral disc prosthesis and instrumentation for insertion of the prosthesis between the vertebrae - The present invention relates to an intervertebral disc prosthesis and insertion instrumentation, the prosthesis comprising at least first and second osseous anchoring means, the first osseous anchoring means disposed proximal to the periphery of the plate on which it is situated and the second osseous anchoring means being offset along the antero-posterior axis, the second osseous anchoring means comprising a basal portion and a sharp-edged portion of width narrower than the basal portion. The instrumentation comprises a rod fitted with at least two feet forming a clip and sliding in a tube, sliding the rod in the tube, in the direction of the manipulation end, causing closing of the clip by contact between the exterior of the feet and a truncated portion of the tube and sliding the rod in the tube, in the direction of the prehension end, causing opening of the clip by contact between an axis and the interior of the feet of the rod. | 01-10-2013 |
20130238030 | SYSTEMS AND METHODS FOR LINKING IMPLANTS AND REDUCING DEFORMITIES - A system for linking bone anchors and reducing spinal deformities includes a first pair of bone screws, a first cross-link, a second pair of bone screws, a second cross-link, and a longitudinal member. The first pair of bone screws attach to opposite sides of a first vertebral level. The first cross-link includes end members that removably attach to heads of the first pair of bone screws and a first coupling feature disposed between the end members. The second pair of bone screws attach to opposite sides of a second vertebral level. The second cross-link includes end members that removably attach to heads of the first pair of bone screws and a second coupling feature disposed between the end members. The longitudinal member links the first coupling feature to the second coupling feature to enable simultaneous positioning of the first vertebral level with the second vertebral level. | 09-12-2013 |
