An acetubular implant includes a cup for receiving an insert freely articulated in the cup, equipped with iliac expansions (8) and a plugging element; the cup consists of a hemispherical part extended by a cylindrical part whereto are attached the iliac expansions. The cylindrical part extends over substantially a half circumference of an equatorial edge of the hemispherical part and is defined by a plane (R) inclined on the equatorial plane. Part of the outer surface of the cup (2) is covered with a macrostructure (24) defining a set of raised parts with a series of equatorial and meridian grooves of predetermined shape such that the macrostructure is neither too rough nor too smooth.
An acetabular implant (1) for a hip prosthesis, comprising a cup (2) which is designed to receive an insert (3) freely articulated in the cup, and which is equipped with iliac extensions (8) and with an obturator element (9) for bone anchoring, which cup comprises a hemispherical part (6) to which the obturator element (9) is fixed and which is continued by a cylindrical part (7) to which the iliac extensions (8) are fixed, wherein said cylindrical part (7) extends over substantially a half-circumference of an equatorial edge of the hemispherical part (6) and is delimited by a plane R inclined on the equatorial plane (P) of the hemispherical part (6), the inclined plane continuing beyond the cylindrical part (7) via a truncated edge (11) of the hemispherical part (6) situated in the same inclined plane (R).
