ABSTRACT:
In an artificial hip joint, in which a tapered cone of a metallic stem is inserted into a tapered hole of a ceramic stem head to be fixed, a truncated conical sleeve having a thickness of 50 .mu.m to 5.0 mm is compressedly held between a wall surface of the tapered hole and an outer circumferential surface of the tapered cone such that they are taperedly engaged with each other. With this artificial hip joint, an increased strength of the stem head, easy production, miniaturization, increased useful life time, safety in use, and the protection of the tapered cone are achieved.
