A polyaxial screw system and method are provided. The system comprises a receiver having a pivot area defined by a pivot joint or a material between a pair of receiver walls or members that permit the receiver walls or members to move or pivot relative to each other so that a dimension of a socket area can be changed. The socket area is defined by socket walls that when at least one of the receiver members pivots relative to another receiver member or wall, a distance between the socket walls gets smaller so that the socket walls can engage and lock against a head of a polyaxial screw.
