Packaging structure of acetabular implants of hip prostheses and placement instruments of these implants comprising implant packages containing different sizes of acetabular implants and a presentation structure of the placement instruments of these acetabular implants, each implant packaging being separated from the other implant packages and containing the cup (50) and the core (51) of an implant of a certain size, wherein said presentation structure comprises at least two sterile instrument packages, physically separated from each other and physically separated from said implant packages, each of them being specific of a different implant size； where a first instrument package contains: - a first test cup (1) of an economical material, such as a plastic material, which allows this test cup to be for single use only, having this first test cup (1) a determined external equatorial diameter corresponding to the external equatorial diameter of the cup (50) of an acetabular implant of a first size； - at least one first test core (3) of an economical material, such as a plastic material, which allows this test core (3) to be of a single use, each first test core (3) having a part of coupling in the cavity formed by the cup (50) of the first size and a connection adapter to the femoral stem (52) to be implanted； A second instrument package contains: - a second test cup (1) of an economical material, such as a plastic material, which allows this cup to be for single use only, this second test cup (1) having an equatorial diameter determined external corresponding to the external equatorial diameter of the cup (50) of an acetabular implant of a second size； - at least a second test core (3) of an economical material, such as a plastic material, which allows this test core (3) to be of a single use, each second test core (3) having a part of coupling in the cavity formed by the cup (50) of the second size and a connection adapter to the femoral stem (52) to be implanted.Es
