    • A vertebral fusion device (40', 51, 51 ',52, 53) comprising a support element configured for insertion between two corresponding vertebral portions of two adjacent vertebrae (10,20), such as spinous processes (12,22) and transverse processes (14,24), or joint surfaces of the vertebral bodies (11,21) or of the facets (13,23), comprising a granular osteosynthesis material (32), preferably in cortico-spongeous chips made of bone bank human bone, which is plastically deformable, and a hollow container body (31, 31 ',41) that contains the osteosynthesis material (32) and has a side wall, for example made with a network of interlaced meshes, and two open end portions (35,45',45") to allow a contact between the osteosynthesis material (32) and respective surfaces of said corresponding vertebral portions, so that the osteosynthesis material (32) is kept in a compressed condition between said corresponding vertebral portions and receives mechanical loads therefrom which promote osteosynthesis. In particular, the side wall of the hollow container body (31,31', 41) is substantially radially inextensible. The fusion devices may form a vertebral fusion system comprising a plurality of devices selected among an intersomatic device (51,51'), an interspinous device (40'), an interarticular device (52), an intertrasverse device (53), in particular the system may comprise an interspinous device (40'), at least one intersomatic device (51,51 ') and a couple of interarticular devices (52) to obtain a primary stabilization of the implant and a successful osteosynthesis.
    • 脊椎融合装置(40',51,51',52,53)包括构造成用于插入两个相邻椎骨(10,20)的两个对应的椎骨部分之间的支撑元件,例如棘突(12,22)和横向 方法(14,24)或椎体(11,21)或小面(13,23)的关节表面,包括颗粒状骨接合材料(32),优选地在由骨库人骨构成的皮质海绵状切片 ,其包含所述骨接合材料(32)并具有侧壁的中空容器主体(31,31',41),所述中空容器主体(31,31',41)具有例如由交织网状网构成的侧壁和两个开口端部(35 ,45',45“),以允许所述骨接合材料(32)与所述对应的椎骨部分的相应表面之间的接触,使得所述骨接合材料(32)在所述对应的椎骨部分之间保持在压缩状态并且接收机械载荷 从而促进骨接合。 特别地,中空容器主体(31,31',41)的侧壁基本上是径向不可延伸的。 融合装置可以形成椎体融合系统,该系统包括多个选自下述装置之间的装置:特别是在一个插入式装置(51,51'),棘突间装置(40'),一个关节间装置(52),一个反转装置(53) 所述系统可以包括棘突间装置(40'),至少一个交流装置(51,51')和一对相关装置(52),以获得植入物的主要稳定性和成功的骨接合术。
