| 摘要 |
The invention relates to an intravertebral prosthesis, in particular for the cervical vertebral column, essentially comprising a first cover plate (1), for connection to a first vertebral body, a second cover plate (2), for connection to a second vertebral body and a prosthesis centre (10), which forms a joint with the second cover plate (2). The prosthesis centre (10) is held by a seat (9, 5) in the first cover plate (1), embodied as a guide device (7, 11, 12). The centre (10) may be inserted into the guide device from the ventral side in the AP direction (A) relative to the first cover plate (1). A stop plate (14) is provided on the ventral edge of the first cover plate which may be displaced in a sliding guide (18), between a locking and a non-locking position.
