Animal StudyEx VivoHighlightedDegradation products of magnesium implant synergistically enhance bone regeneration: Unraveling the roles of hydrogen gas and alkaline environmentMHID-4421003PMID: 398164752025Bioactive MaterialsYuanming An, Haozhi Zhang, Shi’an Zhang, Yuantao Zhang, Lizhen Zheng, Xin Chen, et al.Biodegradable magnesium (Mg) implant generally provides temporary fracture fixation and facilitates bone regeneration. However, the exact effects of generated Mg ions (Mg2+), hydrogen gas (H2), and hydroxide ions (OH-) by Mg degradation on enhancing fracture healing are not fully understood. Here we investigate the in vivo degradation of Mg intramedullary nail (Mg-IMN), revealing the generation of
