A graftless spinal implant for mechanically attaching two adjacent vertebrae includes a body having first and second opposite surfaces. The first and second surfaces include at least one protruding member for securing the body to adjacent vertebrae, wherein the exterior surfaces of the body and the first and second protruding members include a bioactive coating. The bioactive coating can be selected from coatings such as for example, hydroxyapatite. The exterior bioactive coating facilitates the ongrowth/ingrowth of vertebral bone between the implantable spinal fusion device and adjacent vertebrae. Advantageously, this allows the device to avoid the use of a bone graft and/or bone growth agents.
Cette invention se rapporte à un implant vertébral sans greffe servant à fixer mécaniquement deux vertèbres adjacentes et comprenant à cet effet un corps possédant une première et une seconde surface opposées. Ces première et seconde surfaces comprennent au moins un élément saillant servant à fixer ledit corps auxdites vertèbres adjacentes, les surfaces extérieures dudit corps et les premier et second éléments saillants contenant un revêtement bioactif. Ce revêtement bioactif peut être choisi parmi des revêtements tels que l'hydroxyapatite. Ce revêtement bioactif extérieur facilite la croissance/l'interposition de l'os vertébral entre le dispositif implantable de fusion des vertèbres et les vertèbres adjacentes. Un tel dispositif a l'avantage d'éviter l'utilisation d'une greffe osseuse et/ou d'agents de croissance osseuse.
