<p>PURPOSE:To prevent the elution of toxic materials in a metal and to easily optimize physical characteristics, such as modulus of elasticity. CONSTITUTION:The artificial joint 1 is constituted of a spherical head part 2, a metallic neck part 3 next to this part and a metallic stem part 4 next thereto. Of these parts, the stem part 4 is constituted of a relatively large- diameter stem base part 5 and a stem front end part 6 having a convergent shape. A coating layer consisting of a resin material for living bodies, such as, for example, polyetheretherketone, is formed on the outer peripheral surface 71 of a core material 7 for the neck part 3 and the stem part 4.</p> |
