1. A retractor assembly comprising:
a retractor body including a proximal end defined along a first axis and a distal end opposite the proximal end, the proximal end defining an inner surface that faces the first axis, and an outer surface opposed to the inner surface, wherein at least a portion of the retractor body is open so as to define a channel, the channel being elongate along the first axis, and the retractor body further defines at least one flange extending outwardly therefrom between the proximal and distal ends;
an anchor receptacle disposed at the distal end of the retractor body, the anchor receptacle defined along a second axis that extends through the channel, the anchor receptacle having an anchor receptacle proximal end and an anchor receptacle distal end that is spaced from the anchor receptacle proximal end along the second axis, wherein the channel is open from the proximal end of the retractor body toward the anchor receptacle proximal end,
wherein the second axis is offset with respect to the first axis such that 1) an entirety of the proximal end of the retractor body is offset from the second axis in a direction that is perpendicular to the second axis, and 2) the outer surface of the proximal end of the retractor body faces the second axis; and
a locking assembly carried by the anchor receptacle, the locking assembly configured to attach to the retractor body and to a bone anchor that is configured to be driven into an underlying target location of a patient such that the bone anchor is connectable to the retractor body.
