# Implant for an osteosynthesis device, particular for the spine

## 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.
