Abstract
An inner shell for insertion into an outer shell to thereby form a hip joint socket. The inner shell includes an outwardly projecting thread spigot located at a pole with the thread spigot defining a rotational axis and being screwable into an inner thread of the outer shell. The inner shell further includes a projection arranged at the outer edge and extends outwardly radially to the rotational axis. The projection includes at least one locking part that acts on the outer shell, when the inner shell is placed within the outer shell, in order to prevent rotation of the inner shell about the rotational axis.
