Abstract

L'invention concerne une plaque de métal pour fixation osseuse(100) qui présente de multiples premiers trous (120) d'un ensemble de trous circulaires ménagés dans une structure alvéolée à concentration rapprochée, qui se caractérise en ce qu'un second type de trous (130a) de dimensions inférieures aux premiers trous (120) sont également ménagés dans chaque zone entourée, parmi les multiples premiers trous (120), par trois trous adjacents de la catégorie des premiers trous (120a, 120b, 120c) et en ce qu'il n'y a pas de zone en pente en périphérie (116) de la plaque de métal pour fixation osseuse (100). L'invention concerne par conséquent une plaque de métal pour fixation osseuse (100) à haut degré de latitude de pliage ou de cintrage, présentant un risque réduit d'altération de tissus par blessures induites par la périphérie (116) de la plaque de métal pour fixation osseuse (100).
