Abstract:
1. A system comprising: a rod comprising a first end, said rod being wound into a spiral substantially along a first helicoidal curve with respect to a longitudinal axis, a part configured to be inserted between two adjacent vertebrae, said part having at least one pre-formed through-hole in an outer surface adapted to be in contact with a face of one of said two adjacent vertebrae, said pre-formed through-hole having an axial line, means for rotatably driving said rod about the longitudinal axis so that upon rotatably driving the rod, the first end of said rod can move alternately into a bone and out of said bone and for driving said rod outside of the bone so that said first end of the rod moves at least once into said at least one pre-formed through-hole in said part, and the axial line of said at least one pre-formed through-hole being perpendicular to a longitudinal axis of said rod when said rod moves into the at least one pre-formed through-hole.
