ABSTRACT

The implant comprises a part (2) for anchorage in the bone and a body (3) for
fixing on a rod (4), the body comprising two lateral branches (5) defining a
passageway (6) which is open on each side of the body for receiving the rod,
and a screw-threaded plug (8) adapted to be screwed between the branches; a
strip (14), interposed between the plug and the rod, is fixed to a ring (15)
with which it constitutes a pellet (16). The strip (14) is curved and defines
a concave surface (14a) adapted to be applied against the surface of the rod.
The curvature of the strip (14) permits clamping the rod (4) in position with
a relatively small clamping pressure in that the forces are distributed, which
improves resistance to alternating bending of the rod in the body (3) and
resistance to fatigue.
