A spinal fixation system includes a plurality of bone anchors and an array of receiver sub-assemblies, with each bone anchor having a common universal capture portion configured for bottom loading into one of the receiver sub-assemblies that includes at least one of a multiplanar receiver sub-assembly, a monoplanar receiver sub-assembly, and a monoaxial receiver sub-assembly that further include, respectively, a multiplanar retainer sub-assembly for providing pivotal motion of the bone anchor relative to the receiver in multiple planes, a monoplanar retainer sub-assembly for limiting pivotal motion of the bone anchor relative to the receiver to a single plane, and a monoaxial retainer sub-assembly for inhibiting all pivotal motion of the bone anchor relative to the receiver while providing of rotation the monoaxial receiver sub-assembly about the longitudinal axis of the bone anchor.
