Zusammenfassung:PURPOSE:To well disperse body load and tensile force to the lower limbs by constituting the title pelvis of a high hardness molded body enveloped in a tissue membrane and providing three blade parts to the upper part of said molded body while providing a socket part for a hip joint, a long projection for connecting the pubic symphysis and an ischial bone forming part to the lower part thereof. CONSTITUTION:The title pelvis is composed of a high hardness molded body whose surface is preliminarily enveloped in a tissue membrane and three fixed blades 4, 5, 6 are provided to the upper part inserted in the periosteum of said molded body and, when the pelvis 1 is looked from the front, two blades among them are present outside the ala ossis ilium 15 and one of them is present inside the articulatio sacroiliaca of the ala ossis ilium and a part of the sacrum 14 and the ala ossis ilium 15 is supported so as to be grasped by three blades. A socket for a hip joint 25 is provided to the lower part of the molded body at an angle of inclination of about 45 deg. with respect to verticality to be present on a surface of a forward angle of torsion of about 10 deg. and has a long projection 7 for connecting the pubic symphysis 16. The tissue membrane is formed from a fabric, a knitted fabric or a film composed of a polyamide fiber, a polyester fiber, polystyrene or an ABS resin. The high hardness molded body is obtained by using an alumina polycrystalline material, hydroxyapatite or the like as main structural components.
