For a pedicle screw a receiver member is provided for hingedly connecting a screw (2) comprising a threaded shaft portion (3) and a spherical-segment-shaped head (4) on the one hand and a rod (16) on the other hand. In order to improve the stocking costs for screws of different shaft lengths and shaft diameters, the receiver member has a receiver chamber (7) therein, the receiver chamber has a bore (8) at one end thereof for passing the threaded shaft portion (3) followed by an inner hollow spherical-segment-shaped portion (9) for supporting the head of the screw (2) to be received, and an aperture (10) on the side opposite to the bore (8) for inserting the screw (2). Further, a compression member (18) is provided which exerts, in assembled state, a force onto the head such that the head is pressed against the hollow spherical-segment-shaped portion (9). The new receiver member provides that only screws with different screw shafts must be stocked and in operation these screws can be then assembled with the uniform receiver members.
