| 摘要 |
<p>The invention concerns an interbody implant designed to be inserted in the disc space defined between two neighbouring vertebrae, called overlying and underlying vertebrae, the implant having the form of a generally parallelepiped cage (1) comprising at least two sagittal walls (2, 3) interconnected by at least front (4) and rear (5) transverse walls, the walls (2 to 5) having edges (10) extending on one side to define a first transverse surface (8) and on the other side, to define a second transverse surface (9). The invention is characterised in that the implant comprises: one first transverse surface (8) having in the sagittal plane, a convex profile congruent with the sagittal anatomical profile of the overlying vertebra, and a second transverse surface having in the frontal plane a convex profile congruent with the frontal anatomical profile of the underlying vertebra.</p> |
