Artificial hip joint comprising with mechanical damping properties has flattened dome and arrangement of separated, rigid damping rings.

摘要

An artificial hip joint where the metal shell is hemispherical or ellipsoidal, with a flattened dome (17) (polar compartment). The metal shell is hemispherical or ellipsoidal, with a flattened dome (17) (polar compartment). It blends into a band-like equatorial ball segment having recesses in its wall, which separate a rigid internal ring damping against a rigid outer ring (12). The wall of the polar compartment has recesses (13) and/or it is thinned.
