ABSTRACT:
A centro-medullary nailing rod for treating bone fractures, the rod being generally in the form of a longitudinally split tube, and being characterized by the fact that it includes locking tongues (3-4; 5-6) suitable for preventing or limiting relative displacement between the two edges (20-21) of the slot (2) in the longitudinal direction, while allowing relative displacement thereof in the transverse direction. The invention improves the resistant of the rod to twisting.
