A spinal fusion implant assembly (100) for spacing vertebrae is provided. The implant (100) includes two components (102; 104) each having a vertebral contact surface (112; 132), a pair of side portions (106, 108; 126, 128), and an end plate (110; 130). The two components (102; 104) are complementary such that when placed together they form a whole. Each of the sides (106, 108; 126, 128) has a high point (114, 116; 138, 140) and a low point (118, 120; 134, 136), such that a sloped edge of each side is defined between the high point and the low point, and the slope of the first sides (106; 126) is complementary to the slope of the second sides (108; 128). The device also includes a translation mechanism (150) for providing relative motion between the components (102; 104).
L'invention concerne un ensemble greffon (100) d'arthrodèse destiné à espacer des vertèbres. Ledit greffon (100) comprend deux composants (102; 104) présentant chacun une surface de contact (112; 132) avec la vertèbre, deux parties latérales (106, 108; 126, 128), et une plaque d'extrémité (110; 130). Les deux composants (102; 104) sont complémentaires de sorte qu'ils forment un tout lorsqu'on les assemble. Chacune des parties latérales (106, 108; 126, 128) présente un point haut (114, 116; 138, 140) et un point bas (118, 120; 134, 136) de manière que ces deux points définissent entre eux un bord incliné sur chacun des cotés, et que la pente des premiers côtés (106; 126) et la pente des seconds côtés (106; 126) soient complémentaires. Le dispositif comprend également un mécanisme de translation (150) permettant un mouvement relatif entre les composants (102; 104).
