Abstract
The invention shows a double-cup hipjoint socket of oval cross-section with a spherical bearing cup (4). the metallic outer cup (1) exhibits a constant thickness of wall and is provided with openings (3) for anchoring in the pelvic bone. The inner cup (2) of plastics may be latched to the outer cup (1) and by springy tongues (11) on the opposite side. The oval shape is generated by inserting straight intermediate pieces (5,6) in the inner and outer cups. Through the elongated shape of the outer cup (1) which may be inserted in different directions, an optimum fastening may be striven for. The definitive position of the spherical bearing cup (4) is established for the first time by the insertion of a fitting inner cup (2). In doing so the spherical bearing cups (4) may be shifted in the equatorial plane of the outer cup (1) and/or in the direction of the polar axis of the outer cup.
