| 摘要 |
The invention relates to an interbody cage, including a cage body (1) comprising a first and second vertebral bearing element (2a, 2b) each provided with a surface (3a, 3b) capable of bearing against upper and lower vertebrae (4a, 4b), respectively, wherein the first and second vertebral bearing elements (2a, 2b) are capable of being angled relative to one another. The interbody cage further comprises an expansion element (5) to be inserted into the interbody space between the two vertebrae (4a, 4b), then rotatably actuated to expand the interbody space such that the cage body (1) can be inserted therein. The expansion element (5) or other means (6) are arranged so as to vary, in situ, the angle of the first vertebral bearing element (2a) relative to the second vertebral bearing element (2b) of the cage body (1) when the cage body is inserted into the interbody space. |
