Intervertebral implant

An intervertebral implant comprising:

• a spacer having two opposite notches for receiving two spinus processes of two vertebrae, each notch defining a bottom and two flanges, each flange having an inside wall;
• a tie for holding said spacer to said spinus processes, said tie including at least one strap having first and second ends and a portion surrounding a portion of a surface of a spinus process opposite from the bottom of a notch;
• first fixing means formed in at least one of said flanges to fix the first end of said strap;
• and
• self-locking second fixing means comprising a first slot and a second slot, said slots being formed through another one of said flanges, and said second slot being situated between said first slot and the bottom of the notch, the second end of said strap being inserted through said first and second slots and then pulled, so that the second end of said stay is locked by friction, thereby securing the spacer to said spinus processes.

• and
• self-locking second fixing means comprising a first slot and a second slot that are parallel to each other, said slots being formed through at least another one of said flanges, and said second slot being situated between said first slot and the bottom of the notch such that a portion of the strap which passes through the first slot and projects from said inside wall of said another one of said flanges is pressed against a portion of the strap which penetrates into the second slot, thereby enabling the end of said strap to be locked by friction and securing said spacer to said spinus processes.
