Summary:The invention relates to an anterior osteosynthesis plate for lumbar-lumbar or lumbar-sacral vertebrae, the plate being of the type comprising:an elongate body:adapted to cover of the anterior portions of two consecutive vertebrae;possessing an anterior face (6) and an opposite posterior face (7);presenting end zones that are interconnected by a connection zone (11); andprovided with two through holes for anchoring screws.According to this invention, the posterior face (7) of the plate presents a bearing surface (12, 13), which bearing surface is designed to come into contact with the anterior surface (3) of the corresponding vertebra, the bearing surfaces (12, 13)being firstly inclined to define an obtuse angle (alpha) between them in the sagittal plane (S) matching the relative angle between the anterior portions of the two vertebrae, and secondly being interconnected in the connection zone by a concave extension (17) such that at least the posterior face (7) of the body presents a profile that is concave in the sadittal plane.
