Abstract

Abstract Translated from German Die Hüftgelenkspfanne besteht aus einem Kunststoff-Pfannenkörper (1) und einem diesen umgebenden Ring (8) aus Metall. Beide Einzelelemente sind über einen Aussenkonus (6) und einen Innenkonus (7) im Passsitz miteinander verbunden. Dabei rasten Ansätze (10) in Ausnehmungen (11) des Ringes (8) ein und sind durch seitliche Schrägflächen (13) an den Ansätzen (10) bzw. Hinterschneidungen (14) in den Ausnehmungen (11) gegen ein Herausfallen gesichert. The acetabular cup consists of a plastic socket body (1) and a ring (8) made of metal surrounding it. Both individual elements are connected to each other in the snug fit via an outer cone (6) and an inner cone (7). Lugs (10) snap into recesses (11) of the ring (8) and are secured against falling out by lateral inclined surfaces (13) on the lugs (10) or undercuts (14) in the recesses (11). Die neue Pfanne ist bei Kaltfliessen des Kunststoffes selbstfixierend, so dass zu Abrieb führende dauernde Relativbewegungen zwischen Ring (8) und Pfannenkörper (1) vermieden werden. The new pan is self-fixing when the plastic flows cold, so that permanent relative movements between the ring (8) and the pan body (1) leading to abrasion are avoided.
