Determine the in vivo influence of hydrogen bubbles from magnesium corrosion

Determine the exact influence of hydrogen bubbles produced during the in vivo corrosion of magnesium-based implants on healing processes and tissue response.

Background

Hydrogen gas evolution is an intrinsic byproduct of magnesium corrosion and often manifests as bubbles around biodegradable Mg implants. While the present study characterizes corrosion morphologies and osteogenesis phenomena associated with Mg and Mg-Zn wires, the specific physiological and healing implications of hydrogen bubbles remain unsettled in the broader literature and are acknowledged by the authors as unresolved.

Clarifying the role of hydrogen bubbles is critical for assessing safety, optimizing implant design, and interpreting in vivo outcomes, including potential effects on bone formation and local tissue interactions.
