Disclosed is a novel connection assembly for a spinal implant system having: novel interface element having an internal stop that limits rotation of the spinal implant rod and associated members with regard to the spinal implant bolt and associated members allowing the implant system to initially assume a position that approximates its final adjusted position and allows the assembly's size to be reduced without sacrificing its mechanical strength; a compressible member located between the interface elements that ensures free rotation of the spinal implant rod and its associated members in relation to the spinal implant bolt and its associated members until a proper position has been obtained and allows an initially secured system to be repositioned without additionally separating the interface element's locking structures; and components provisionally secured to prevent disengagement during transportation and handling that can be engaged during installation utilizing minimal force with common hand tools.
