Abstract
The invention relates to a surgical implant intended to maintain and assist with the relative movement with respect to one another of two successive vertebras so as to obtain dynamic stabilization, said implant comprising an upper piece (2) and a lower piece (3) which are intended each to be associated with the processus spinosus, or spinal process, of one of said vertebras, said pieces each comprising a means (4, 5) of association with a spinal process and means of connection to the other piece. According to the invention, said connecting elements are designed to collaborate in such a way as to form a pivot joint, at least one of said connecting elements being a visco-elastic element.
Claims9
A surgical implant including two articulated pieces (2, 3), each of said pieces including means of association (4, 5) with a spinal process of two successive vertebras respectively, characterised in that said pieces include respective connecting elements (20, 30) adapted for collaborating in such a way as to form a pivot joint, one of said connecting elements (30) being a visco-elastic element.
An implant according to any one of the preceding claims, characterised in that it further includes means (50, 51, 52;
- 150, 151, 152) for locking said connecting elements.
An implant according to any one of the preceding claims, characterised in that said connecting elements (30, 20) are two respectively male and female elements of a ball joint, clamping means (50, 51, 52;
- 150, 151, 152) making it possible to limit the movement between the pieces to a pivoting movement.
