A connector assembly for interconnecting a bone fastener and a spinal rod, the connector assembly extending generally along a first assembly axis and comprising: a connector extending generally along a second rotational axis which transverses the assembly axis, and the connector having a first end and a second end disposed in co-axial orientation to one another, the first end defining a first cavity around the assembly axis and the second end of the connector adapted to be coupled to the bone fastener; a spinal rod receiver having a receiver body coupled to a collar, the collar defining a fifth internally threaded cavity, in co-axial orientation with the receiver body, the receiver body defining a second implant cavity around a third axis which transverses the assembly axis, the second implant cavity for receiving the spinal rod, the rod receiver attachable to the first end of the connector for selectively adjusting the direction of at least a portion of the rod, when received in the second implant cavity, in a coronal plane; a washer having an upper face and a lower face, the washer defining a third cavity around the first assembly axis substantially circumscribing and slidingly coupled to the receiver body, the upper face of the washer being splined or ridged; and a compression member having a hexagonal nut coupled to a retaining flange, the retaining flange defining a fourth internally threaded cavity around the first assembly axis, the fourth internally threaded cavity for receiving the hexagonal nut, and the hexagonal nut having an externally threaded shaft extending through the third cavity of the washer and engaging the fifth internally threaded cavity of the collar to secure at least a portion of the rod into the receiver body. a connector extending generally along a second rotational axis which transverses the assembly axis, and the connector having a first end and a second end disposed in co-axial orientation to one another, the first end defining a first cavity around the assembly axis and the second end of the connector adapted to be coupled to the bone fastener; a spinal rod receiver having a receiver body coupled to a collar, the collar defining a fifth internally threaded cavity, in co-axial orientation with the receiver body, the receiver body defining a second implant cavity around a third axis which transverses the assembly axis, the second implant cavity for receiving the spinal rod, the rod receiver attachable to the first end of the connector for selectively adjusting the direction of at least a portion of the rod, when received in the second implant cavity, in a coronal plane; a washer having an upper face and a lower face, the washer defining a third cavity around the first assembly axis substantially circumscribing and slidingly coupled to the receiver body, the upper face of the washer being splined or ridged; and a compression member having a hexagonal nut coupled to a retaining flange, the retaining flange defining a fourth internally threaded cavity around the first assembly axis, the fourth internally threaded cavity for receiving the hexagonal nut, and the hexagonal nut having an externally threaded shaft extending through the third cavity of the washer and engaging the fifth internally threaded cavity of the collar to secure at least a portion of the rod into the receiver body.
