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.

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.
