To target this pathological cascade, trimetallic nanoparticles (TriNPs) are designed and developed to modulate the oxidative microenvironment of intervertebral discs and restore ECM homeostasis through reactive oxygen species (ROS) scavenging. In vitro studies demonstrate that TriNPs provide significant cytoprotection against H\n                    <jats:sub>2<\/jats:sub>\n                    O\n                    <jats:sub>2<\/jats:sub>\n                    \u2010induced oxidative damage in nucleus pulposus (NP) cells through efficient ROS elimination. For translational applications, TriNPs are encapsulated within an injectable hydrogel (termed TOH) to evaluate their therapeutic potential in a rat IVDD model. In vivo studies encompassing both radiographic and histomorphometric analyses reveal that TOH administration significantly improves the Disc Height Index (DHI) and T2\u2010weighted Magnetic Resonance Imaging (MRI) grading, while also reducing histological scores. Collectively, these results indicate that TOH may serve as an innovative therapeutic approach to modulate disc microenvironment and attenuate IVDD progression.\n
