Improved wound closure (mean difference -1.48 mm) did not reach statistical significance (d = 1.06). By day 28, magnesium-treated wounds showed improved collagen organization and normalized epidermal thickness. The increase in dermal appendages (247%), and vascular density (41%) did not reach statistical significance. Micro-CT confirmed progressive wire degradation. Modeling revealed that degrading wires dynamically altered strain gradients in healing tissue, thereby modulating the spatial mechanical cues that govern fibroblast migration and extracellular matrix (ECM) remodeling.<\/jats:p>\n                <\/jats:sec>\n                <jats:sec>\n                  <jats:title>Innovation<\/jats:title>\n                  <jats:p>Magnesium is an essential trace element involved in cellular processes critical to wound repair, including angiogenesis, nerve growth, inflammation modulation, and ECM remodeling.
