Abstract:
1. A prosthetic device comprising: a body; a cap made of metal material, having inside an acetabular seating, said cap having an internal wall that lines the seating and an external part consisting of a lattice with cells making a plurality of cavities disposed three-dimensionally, open and intercommunicating, connected with each other, said lattice being solid with the external part facing toward the outside of the internal wall, at least part of the lattice is formed, without a break in continuity, by a plurality of geometric meshes of polygonal shape repeated in space over all or part of the body, having a cellular geometry with elementary cells open and contiguous, to define a plurality of polygons with a spatial development delimiting the cavities, so the lattice is able to promote osteo-integration, wherein each geometric mesh is formed by a first polygonal part with four sides, each of said four sides formed as an angled segment, and a second part formed as an angled segment and a third part formed as an angled segment, wherein each angled segment has first and second consecutive rectilinear segments, wherein an angle is formed in the angled segment at an intersection of each pair of its first and the second consecutive segments; wherein the first polygonal part has vertexes that are not co-planar; the second and the third part with angled segments are disposed transversely to the first part substantially across a respective median line of the first part, crossed with respect to each other, superimposed on the first polygonal part, one on one side and one on the other side to define in the space a plurality of hexagons having vertexes that are not co-planar, the first part and the second part forming a first hexagon and a second hexagon of said plurality of hexagons having vertexes that are not co-planar; the first part and the third part forming a third hexagon and a fourth hexagon of said plurality of hexagons having vertexes that are not co-planar; wherein a first end of a first angled segment of the second part coincides with a first vertex of the first part and a second end of a second angled segment of the second part coincides with a second vertex of the first part; and wherein a first end of a first angled segment of the third part coincides with a third vertex of the first part and a second end of a second angled segment of the third part coincides with a fourth vertex of the first part.
