Abstract

Przedmiotem zgłoszenia jest endoproteza stawu biodrowego, która jest złożona z trzpienia (1), który na połączeniu z główką kulistą (4) ma odcinek szyjki walcowej (2) zwężający się promieniowo do końcówki walcowej (3). Utworzony odcinek powierzchni kulistej (22) styka się bezpośrednio z powierzchnią czołową półpierścienia dolnego (8) i powierzchnią czołową nadlewu (7). W trakcie przywodzenia, jak i odwodzenia kończyny dolnej odcinek powierzchni kulistej (22) przylega ściśle do pierścienia dolnego (8) i nadlewu (7) przez co zwiększa się docisk panewki do kości biodrowej i zabezpiecza endoprotezę przed wyrwaniem z kości biodrowej.The subject of the application is a hip joint endoprosthesis, which consists of a stem (1) which, at the connection with the ball head (4), has a section of the cylindrical neck (2) radially tapering to the cylindrical tip (3). The created section of the spherical surface (22) is in direct contact with the front surface of the lower half ring (8) and the front surface of the sprue (7). During adduction and abduction of the lower limb, a section of the spherical surface (22) adheres closely to the lower ring (8) and the sprue (7), which increases the pressure of the acetabulum on the hip bone and protects the endoprosthesis against being pulled out of the hip bone.
