Abstract

Dispositif de fixation osseuse (10) comprenant une plaque allongée (12) comportant au moins deux paires d'ouvertures circulaires (24)(26) et une série d'ouvertures circulaires (62) placées le long de ladite plaque (12). Les ouvertures circulaires constituent chacune une cavité (30) dont les parois (31) s'étendent entre les surfaces supérieure (16) et inférieure (18) de la plaque, ces cavités possédant des diamètres plus petits (32) au niveau des surfaces de la plaque (16) (18) et un diamètre plus grand (34) entre lesdites surfaces. Ces cavités présentent la forme de deux cônes inversés (31a)(31b) possédant des bases circulaires correspondantes (31c), ce qui permet d'incliner une vis osseuse implantée (14). Une pluralité de vis osseuses (14) possèdent chacune une première partie d'extrémité filetée (36) et une deuxième partie d'extrémité agrandie ellipsoïdale (40). Une élément de verrouillage (48) est relié à la deuxième partie d'extrémité (40) de chaque vis osseuse (14) afin de dilater ladite deuxième partie (40), de manière se fixer à la paroi (31) de la cavité de la plaque (12).
