1. A system for use in minimally invasive spine surgery, the system comprising:
a bone anchor having:
first and second arms that are spaced from one another such that the first arm is spaced from the second arm in a first direction, and the second arm is spaced from the first arm in a second direction that is opposite the first direction,
wherein the first and second arms have first and second inner surfaces, respectively, that face each other and define a rod-receiving channel therebetween, and first and second outer surfaces, respectively, that are opposite the first and second inner surfaces, wherein the first arm defines a first recess that extends into the first outer surface and terminates in the first arm with respect to both the third direction and a fourth direction that is opposite the third direction;
a first tissue retractor that extends from the first arm but not the second arm along a third direction that is perpendicular to each of the first and second directions, the first tissue retractor defining a first concave inner surface, and the first tissue retractor defining a first tissue retractor length that extends along the third direction from the first arm to a free end of the first tissue retractor; and
a second tissue retractor that extends from the second arm but not the first arm along the third direction, the second tissue retractor defining a second concave inner surface that faces the first concave inner surface, and the second tissue retractor defining a second tissue retractor length that extends along the third direction from the second arm to a free end of the second tissue retractor,
wherein the first tissue retractor includes a first resiliently movable arm that is movable between an engaged position and a flexed position, such that a first tab that projects from the first resiliently movable arm in the second direction extends into the first recess when the first resiliently movable arm is in the engaged position so as to secure the first tissue retractor to the first arm of the bone anchor.
