<p>The invention concerns an implantable device for fixing a rod (20) in a rather thin bone wall (EO) comprising two parts (10, 10) each comprising a body (11) with a passage (12) for receiving the rod, and a curved hook (13) extending laterally relative to the body. Each hook (13) is shaped such that the two hooks facing each other can be simultaneously inserted, by mutually tilting the two parts urging their bodies closer to each other, in an opening (T) arranged in the wall, and be mutually spaced rearwards as said bodies are brought closer to each other. The rod (20) received in said passages (12) of the two bodies (11) is capable of preventing any reverse tilting of said parts (10). The invention is particularly useful for fixing a rod for backbone osteosynthesis in the flat part of the skull occipital bone.</p> |
