1. A pedicle screw-mounted retractor system, comprising:
a first and a second retractor blade body having a proximal and distal end, a proximal shoulder, an inside diameter, a first partially offset non-concentric outside diameter and a second partially concentric outside diameter; and
a first and a second locking shim;
wherein each of the first and second locking shim comprises a leg, a distal L-shaped foot, an opposing proximal top flange projecting away from the distal L-shaped foot, and
wherein each of the first and second locking shim is configured for removable locking placement between two or more tangs of a pedicle screw tower of each of the first and a second pedicle screw, within each diametral retractor blade body;
a proximal end flange extending perpendicularly on one side of each retractor blade body, comprising a first receptacle configured to receive the proximal top flange of the locking shim and a second receptacle to receive a post sub-assembly; and
a post sub-assembly extending distally from the second receptacle,
wherein each said post sub-assembly is configured to lockably receive a handle or a mounting arm of a spinal joint retractor,
wherein each of the first and second retractor blade body comprises a longitudinal diametral tube configured with a proximal opening, a distal opening, and through bore,
wherein each of the first and second retractor blade body is configured for placement over and onto an extended tulip of a first and a second pedicle screw, each pre-positioned in a pair of adjacent caudal and cephalad vertebrae on a same side of a spine and configured for distracting the vertebrae, and
wherein each retractor blade body further comprises at least one visualization slot through one side of the retractor blade body, said at least one visualization slot positioned diametrically opposite the side having the proximal end flange.
