1. A system comprising:
a bone anchor assembly; and
a guide member, having a longitudinal axis, for positioning and angulating the bone anchor assembly, the guide member comprising:
a proximal end and a distal end,
a lumen extending from the proximal end to the distal end,
a pair of opposed longitudinal rod slots opening to the distal end and extending proximally for a length along the guide member and contiguous with the lumen, to form a rod channel dimensioned to guide a spinal rod into the bone anchor assembly;
a bone anchor engagement feature at the distal end; and
a side track extending longitudinally between the pair of opposed longitudinal rod slots,
wherein the side track is configured to receive a guide member attachment feature of a pivot rack, wherein the guide member attachment feature has a broad portion and a narrower portion to allow the guide member attachment feature to be freely slid in the side track while constrained from moving radially with regard to the guide member, and
wherein the guide member is configured to rotate around a rotation axis perpendicular to the longitudinal axis when the guide member attachment feature is seated in the side track.
