| 摘要 |
The invention relates to an intersomatic implant for insertion in the intervertebral space defined between two adjacent lumbar vertebrae, referred to as an overlying vertebra and an underlying vertebra, in order to reestablish the anatomical shape of the intervertebral space. According to the invention, the implant includes at least one spacer ramp (12a, 13a, 13b): extending between the anterior and posterior transverse walls (4) so as to project relative to a transverse face (8) in order to determine relative spacing between the underlying and overlying vertebrae while the implant is being inserted into the intervertebral space; and presenting a profile which is to be found circumscribed inside the intervertebral space in which the implant is to be placed.
