1. A spinal support system, comprising:
a first rod receptacle for mounting to a pedicle screw, said first rod receptacle having a first side wall defining a first pair of diametrically opposed slots that extend axially along said first side wall and are open at a proximal end of said first rod receptacle; and
an extension assembly including a second rod receptacle mounted to a base portion, said second rod receptacle including an internal flange having an interior face and defining an axial thickness, said base portion including a mounting platform, said second rod receptacle having a second side wall defining a second pair of diametrically opposed slots that extend axially along said second side wall and are open at a proximal end of said second rod receptacle, said extension assembly including a pivot member that includes a head portion and a shaft portion, said shaft portion being in fixed relationship with said mounting platform to define an axial gap dimension between said head portion and said mounting platform, said internal flange of said second rod receptacle being captured between said head portion and said mounting platform, said axial gap dimension being greater than said axial thickness of said internal flange to enable rotation of said extension rod receptacle about said head portion,
wherein said interior face of said internal flange of said second rod receptacle conforms to said head portion to limit said rotation of said extension rod receptacle about said head portion to a substantially monoaxial rotation.
