Title (EN) SURGICAL METHOD AND APPARATUS FOR FUSING ADJACENT BONE STRUCTURES
(FR) PROCEDE ET APPAREILS CHIRURGICAUX POUR SOUDER DES STRUCTURES OSSEUSES ADJACENTES
Abstract:
(EN) A fusion cage (10) having an external thread (12) can be surgically inserted into a threaded bore extending laterally between the adjacent bony structures such as two vertebrae (94, 95) with the thread (12) penetrating into cancellous bone of each of the vertebrae (94, 95). The fusion cage (10) is easily screwed into place by hand without damage to the bony structures (94, 95). Cage (10) is then packed with a bone-growth-inducing substance such as cancellous bone. When a pair of such cages (10) are implanted between adjacent vertebrae (94, 95), patients have been able to sit without pain by the second or third day, much earlier than has been possible in prior spinal fusions except those involving steel plates and screws. Eventually, the ingrowth of bone through perforations (13) in the valley (14) of the thread (12) of the fusion cage (10) forms a permanent interconnection between the two bony structures (94, 95).
(FR) Une cage de soudure (10) présentant un filetage externe (12) peut être implantée par voie chirurgicale dans un alésage fileté s'étendant latéralement entre les structures osseuses adjacentes, telles que deux vertèbres (94, 95), le filetage (12) pénétrant dans l'os spongieux de chacune des vertèbres (94, 95). La cage de soudure (10) est aisément mise en place manuellement par vissage sans endommager les structures osseuses (94, 95). La cage (10) est ensuite garnie d'une substance déclenchant la croissance osseuse, telle que de l'os spongieux. Lorsqu'une paire de ces cages (10) sont implantées entre des vertèbres adjacentes (94, 95), les patients sont en mesure de s'asseoir sans douleur dès le deuxième ou troisième jour, bien plus tôt que cela n'était possible dans des soudures spinales antérieures en dehors de celles mettant en ÷uvre des plaques d'acier et des vis. Enfin, la croissance interne de l'os à travers les perforations (13) dans le creux (14) du filetage (12) de la cage de soudure (10) forme une interconnexion permanente entre les deux structures osseuses (94, 95).
