Abstract: A two step locking screw assembly includes a receiving member for receiving a fixation member and an anchor having an enlarged portion and a shank. The enlarged portion of the anchor may be seated in the receiving member. An insert may also extend inside the receiving member. An outer fastener may be positioned in the receiving member. The outer fastener may include a central opening and a pair of ramped flanges. An inner fastener may be disposed inside the central opening of the outer fastener.

Abstract: A rod to rod connector includes at least one clamping assembly for receiving a first spinal rod. The clamping assembly may include a polyaxial articulation element. The articulation element may include a hollow body forming an opening. The clamping body may further include a pivot element configured to clamp the first spinal rod between the pivot element and a channel wall in the clamping assembly. The rod to rod connector may also include a connector member for connecting the clamping assembly to a second spinal rod. The connector member may include a socket configured to receive the polyaxial articulation element of the clamping assembly, with the articulation element polyaxially rotatable relative to the axis of the socket.

Abstract: A low profile spinal stabilization system according to one embodiment includes an elongated fixation element having a socket. The system also includes an anchor element having a spherical end for insertion into the socket of the elongated fixation element, the spherical end having a plurality of petals separated by a plurality of radially arranged slots. The system further includes a locking element for insertion into the spherical end of the anchor element to lock the spherical end of the anchor element inside the socket of the elongated fixation element.
