摘要
The invention relates to a self-fixating trial socket for releasable insertion into a corresponding cavity in a hip bone. The self-fixating trial socket comprises an outer surface, which is matched to the cavity in the hip bone, an inner surface, which is matched to an inlay, especially a trial inlay, and/or to a ball joint head, for receiving the latter in the hip joint socket, especially self-fixating trial socket, and at least one holding element for fixating the hip joint socket in the cavity, the at least one holding element comprising at least one spring element which is constructed in such a way that in the inserted state the spring element exerts, at least in some places, an outwardly directed spring force on the cavity in the hip bone for releasable fixation of the hip joint socket.
