| 摘要 |
The invention concerns a vertebral implant (1) adapted to be inserted from the rear in an intervertebral space (2), characterised in that it comprises two arms (3) articulated about a transverse axis (4) located in the proximity of one end (5) of said arms opposite their insertion end (6) into the intervertebral space, and means (7, 8, 12) for adjusting the angular opening of the arms, adapted to co-operate with the inner surface of the arms between the insertion end and the hinge axis. The two arms (3) are identical and have a double external curve corresponding to the convexo-concave surface of the supporting vertebral end-plate, and the arms (3) are globally wedge-shaped when they are closed on each other, thereby facilitating the insertion of the implant (1) in an intervertebral space as well as its removal, if required.
