| 摘要 |
The invention concerns an intervertebral implant comprising a wedge designed to be pressed between two spinous processes, said wedge having two opposite grooves each defined by two wings, the axes of said two grooves being substantially mutually parallel and said spinous processes being urged to be supported in said two grooves. The wedge (10) comprises at least a central recess (16) between said two grooves (12, 14), said central recess (16) passing right through said wedge (10) along an axis Ac substantially parallel to said axes Ag1 and Ag2 of said grooves, thereby making said wedge (10) is elastically deformable.
