Abstract
The invention relates to an expandable socket () for a hip joint endoprosthesis able to be cementlessly anchored in place which is at least approximately hemispherical and which is provided with a plurality of slots () extending in a meridional direction, thus forming intervening tongues (), on which are formed projections () that form a plurality of rows () extending from an equator () of the expandable socket (). The projections () are arranged on the tongues () in such a manner that a row () of projections () arranged in the center of the tongue () extends on a meridian () of the hemispherical socket () while at least one adjoining row () of projections () extends in a line that extends at all points in parallel to the meridian () of the row () of projections () arranged in the center and not through a pole () of the hemispherical expandable socket ().
