Peri‐implant gas accumulation in response to magnesium‐based musculoskeletal biomaterials: Reframing current evidence for preclinical research and clinical evaluation J. Magnes. Alloys (IF 17.6) Pub Date : 2024-01-23 Yu Sun, Heike Helmholz, Regine Willumeit-Römer
Historically, the rapid degradation and massive gas release from magnesium (Mg) implants resulted in severe emphysema and mechanical failure. With the advent of new alloys and surface treatment methods, optimized Mg implants have re-entered clinics since last decade with reliable performance. However, the optimization aims at slowing down the degradation process, rather than exemption of the gas release
