Intervertebral Connecting Device

An intervertebral connecting device, which is intended to connect at least two vertebrae together, this device being characterized in that it includes:

• at least one stationary element (2;
• 2′;
• 2″;
• 2′″;
• 52, 53;
• 152, 153), connected with a vertebra or the sacrum,
• at least one mobile connecting element (10;
• 10′;
• 10″;
• 10′″;
• 60;
• 110;
• 165;
• 215;
• 265;
• 315) capable of moving with respect to the stationary element or each stationary element,
• as well as at least one intermediate element (22;
• 22′;
• 22″;
• 22′″;
• 72;
• 172, 172′) allowing the articulation of the mobile element or each mobile element with respect to the stationary element or each stationary element,
• in that the intermediate element or each intermediate element is received in interior volume (16;
• 16′;
• 116;
• 167, 169;
• 217, 227;
• 327) of said mobile element (10;
• 10′;
• 10″, 10′″;
• 110;
• 165;
• 215;
• 265;
• 315) or of said stationary element (52, 53),
• in that stationary element (2;
• 2′;
• 2″;
• 2′″;
• 152, 153) or mobile element (60) is received at least partially in interior volume (26;
• 26′) of the intermediate element,
• and in that it is provided with some means allowing the connection, at least in translation, of said element (2;
• 2′, 2″;
• 2′″;
• 152, 153) or of said mobile element (60) with respect to said intermediate element, these means of connection in translation including the periphery of outlet (27), which is essentially rigid, of interior volume (26) of intermediate element (22).
