1. An intradiscal shield configured to provide structural integrity to a spinal disc having a spinal defect, the intradiscal shield comprising:
an outer barrier defining an inner portion,
wherein the inner portion defines a bore,
wherein the bore is configured to transition between an open configuration and a closed configuration,
wherein, in the open configuration, the bore provides an opening for spraying a protein crosslinking reagent therethrough;
a first side configured to face a central cavity of the spinal disc;
a second side, opposite the first side, and configured to face outwardly from the central cavity,
wherein the second side comprises an instrument engagement member,
wherein the bore extends through the inner portion and the instrument engagement member,
wherein the instrument engagement member comprises one or more stabilizers configured to stabilize the intradiscal shield; and
one or more anchors extending from the outer barrier and angled acutely toward the second side,
wherein distal translation of the intradiscal shield into the spinal defect bends the one or more anchors inwardly toward the outer barrier during insertion of the intradiscal shield into the spinal defect,
wherein, when the intradiscal shield is inserted into the spinal defect, proximal biasing of the intradiscal shield inserts the one or more anchors into perimeter tissue of the spinal defect to maintain a position of the intradiscal shield within the spinal defect,
wherein the one or more stabilizers extend through the inner portion and connect to the one or more anchors.
