Implication

Review evaluates degradation mechanisms and mechanical integrity in biodegradable metal alloys, highlighting strategies to balance implant corrosion with tissue healing.

Key Points

To review recent advances, ongoing challenges, and design strategies in balancing mechanical strength, corrosion rates, and biocompatibility in biodegradable metallic implants.
Synthesized literature on iron-, magnesium-, and zinc-based biodegradable alloy systems.
Assessed the impacts of alloy formulation, thermomechanical processing, porous scaffold architectures, surface modifications, and additive manufacturing on degradation and mechanical integrity.
Iron, magnesium, and zinc alloys each exhibit distinct trade-offs between load-bearing strength, degradation velocity, and host tissue biocompatibility.
Implant survival depends heavily on managing the dynamic interplay between progressive mechanical loading and ongoing material loss from corrosion.
Future clinical translation requires standardized benchtop degradation testing, extended in vivo validation, and optimized manufacturing strategies.
