1. A spinal shield comprising:
a shield body forming a top side, a bottom side that collectively define a front side, a rear side, a first lateral side, and a second lateral side opposite the first lateral side, the shield body being configured for temporary placement over a bodily structure within an operative field for protection of the bodily structure;
a plurality of lateral extensions that extend outwardly from the shield body; wherein the plurality of lateral extensions are configured for temporary placement over tissues lateral to the bodily structure associated with the shield body when the shield body is placed within the operative field; and
a handle portion that extends outwardly in perpendicular relation to the shield body, wherein the shield body and each lateral extension of the plurality of lateral extensions are removeable from the operative field following installation of hardware between the plurality of lateral extensions, and
wherein each lateral extension of the plurality of lateral extensions includes a hinge positioned along the shield body that permits rotation of the plurality of lateral extensions below the first lateral side and the second lateral side of the shield body and prevents rotation of the plurality of lateral extensions above the first lateral side and the second lateral side of the shield body when the shield body is placed within the operative field to allow removal of the spinal shield from the operative field following installation of hardware between the plurality of lateral extensions within the operative field.
