The bone augmentation device is used for attachment of soft tissues to bone by means of sutures. It comprises a curved bone plate (1) with several through holes (2). The bone plate (1) lies in a curved plane (3) having a curvature R PL, in the range of 25 to 100 mm. The edges (4) of the plate (1) are rounded with a curvature R EP in the range of 0,2 to 0,7 mm and the edges (5) of the through holes (2) are rounded with a curvature R EH in the range of 0,2 to 0,8 mm. The device according to the invention prevents the suture from cutting through the bone and prevents gapping between the soft tissue (tendon) and bone which would result in a poor healing. The consequence is that a stable repair will facilitate healing. Dispositif d'augmentation osseuse servant à fixer des tissus mous à l'os par l'intermédiaire de sutures. Il est composé d'une plaque vissée incurvée (1) comportant plusieurs perçages (2). Cette plaque vissée (1) est située dans un plan incurvé (3) dont l'incurvation RPL est située entre 25 et 100 mm. Les bords (4) de la plaque (1) sont arrondis selon une incurvation REP située entre 0,2 et 0,7 mm. Les bords (5) des perçages (2) sont arrondis selon une incurvation REH située entre 0,2 et 0,8 mm. Ce dispositif empêche la suture de couper l'os et évite l'apparition d'un espace entre le tissu mou (tendon) et l'os, en qui entraînerait des difficultés de guérison. Il permet d'obtenir une répartition stable facilitant la guérison.
