<p>The invention relates to an extra-discal system for connecting a first vertebra to a second vertebra. The system comprises a first element (1) for rigidly connecting to the first vertebra, a second element for rigidly connecting to the second vertebra, a connector (2) arranged so as to be rigidly connected to the first rigid connection element (1), and an intervertebral connection member (3, 3', 3") arranged so as to be connected or built into the connector (2) and the second rigid connection element. The system further comprises means (4, 4', 5, 5', 7, 7', 8, 8") for articulating the connection member (3, 3', 3") and the connector (2), or the first rigid connection element (1) and the connector (2), or the first rigid connection element (1), the connector (2) and the connection member (3, 3', 3"). Said articulation means (4, 4", 5, 5', 7, 7', 8, 8') are arranged so as to enable a displacement movement among the articulated parts when the system is assembled.</p> |
