(57) Abstract : A spinal implant assembly comprises a connection assembly, an elongated spinal implant, and a bone fastener. The connection assembly includes a body defining a first opening for receiving the elongated spinal implant, a second opening for re- ceiving a bone fastener and a plug. The first opening is perpendicular to and overlapping the second opening to allow direct contact between the spinal implant and the bone fastener. The second opening includes a plug slot having a wall at an end opposite the first opening that defines an engagement surface. The plug includes a mating surface that forms an interlocking engagement with the engagement surface of the wall. An opposite second surface of the plug defines a groove for receiving the elongated stem of the bone fastener adjustable to a desired angular orientation and height. The connection assembly further comprises means for urging the elongated spinal implant to press against the bone fastener and the plug which, subsequently, is pressed against the engagement surface of the wall.
