Beschreibung
Zusammenfassung:An acetabular prosthesis (1) for hip arthroplasty, comprising a metal- back (3) in which a cavity (5) is formed which is adapted to accommodate an insert (7) and which comprises a first region (50) having a substantially hemispherical internal surface (52) from which a second region (54) extends which has a substantially cylindrical internal surface (56), the height of the second region (54) being comprised in the interval between 1 and 5 millimeters and being adapted to help to retain the insert (7) in the cavity (5). La présente invention concerne une prothèse acétabulaire (1) servant à une arthroplastie de la hanche, comprenant une partie arrière métallique (3) dans laquelle est formée une cavité (5) qui est conçue pour loger un insert (7) et qui comprend une première zone (50) présentant une surface interne sensiblement hémisphérique (52) depuis laquelle s'étend une seconde zone (54) qui présente une surface interne sensiblement cylindrique (56), la hauteur de la seconde zone (54) étant comprise dans l'intervalle entre 1 et 5 millimètres et étant conçue pour aider à retenir l'insert (7) dans la cavité (5).
