摘要: A hip joint femoral prosthesis has a rod (2), the proximal end (6) of which has a cross-section of oval shape and a surface area increasing towards the proximal end. At least one wall of the proximal end includes alveoli (9) therein hollowed out so as to present a maximum depth on their side towards the proximal end. The alveoli are of a circular or semi-circular shape and intersect, thereby providing a surface which improves the stability and anchoring of the prosthesis into the femur.

摘要: An acetabular prosthesis assembly for implantation into a prepared acetabulum has a generally hemispherically-shaped cup (1). The cup (1) has a substantially hemispherically-shaped inner surface (2) and a substantially hemispherically-shaped outer surface (3) defining a wall therebetween. The wall has a plurality of generally circular apertures (6, 7, 8) therein for receiving a bone screw. The wall surrounding each aperture has a bevelled surface extending toward the outer surface (3) followed by a generally cylindrical surface extending from the bevelled surface to the outer surface of the cup. The generally cylindrical surface of each aperture (6, 7, 8) is threaded with threads of predetermined diameter and pitch. A bone screw has a first screw thread having a pitch and diameter for engagement with the thread of the cylindrical surface on the cup and a second screw thread having a major diameter and a pitch greater than the predetermined diameter and pitch of the cylindrical surface. A plastic insert for attachment to the inner surface of the cup is provided.

摘要: The invention relates to an acetabulum cup for a total prosthesis of the hip.
The prosthesis (1) in the form of a spherical cap comprises threaded blind holes (4, 4') on its convex outside surface (3).
The entirely smooth inside surface (2) prevents the premature wear of an insert made of plastic material interposed between it and the head of the femoral part of the prosthesis.摘要翻译: 本发明涉及一种用于髋关节全假体的髋臼杯。 球形帽形式的假体(1)包括在其凸出的外表面(3)上的螺纹盲孔(4,4')。 完全光滑的内表面(2)防止插入塑料材料的插入件与假体的股骨部分头部之间的过早磨损。
