Following the initial injury, glial scarring and extracellular matrix barriers prevent axonal regeneration, while secondary damage exacerbates inflammation and tissue loss. The gold standard treatment in the last decades is acute surgery and systemic drug administration. New technologies have been developed, such as stem cell therapies, or the combinatory use of biomaterials, nonetheless still offering limited recovery. Successful therapies must act directly on neurons, activating regenerative pathways, while simultaneously promoting a pro-regenerative environment. However, polymeric materials have, in recent years, shown a regenerative potential through a series of different processes, from promoting neural regeneration by supporting tissue repair and reducing inflammation, to local drug delivery mechanisms. In this work, we systematize the state-of-the-art, exploring recent advancements in polymer-based therapies for spinal cord injury, discussing their characteristics, limitations, and promising future applications.<\/jats:p>","DOI":"10.4103\/nrr.nrr-d-25-00460","type":"journal-article","created":{"date-parts":[[2025,10,31]],"date-time":"2025-10-31T08:00:13Z","timestamp":1761897613000},"page":"3943-3951","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":0,"title":["Repairing
