Radiofrequency Induced Heating of Biodegradable Implants

Sargut Peter

In orthopaedic surgery, magnesium (Mg)-based implants have reemerged as an alternative to permanent implants. The degradation of biodegradable implants may have safety implications for medical imaging-based patient follow-up, but little is known about this. Post-surgery monitoring of the healing of the bone and the implantation sites is made easier with magnetic resonance imaging (MRI). Electromagnetic fields used in MRI were found to cause permanent implants to be heated by radiofrequency (RF). The degradation layer’s effect on RF-induced heating of biodegradable orthopaedic implants is first reported in our study
