Abstract Scope |
Measurement of in vivo degradation progression for biodegradable metals such as magnesium remains of utmost importance for customer satisfaction and regulatory purposes. Current methods base on CT/X-ray or MRI approaches that generally provide results with inappropriate validity. Approaches via MRI are heavily impacted by the exact position and orientation of the implant in the
magnetic field and final evaluation is affected by subjective assessment. CT scans expose the patients to radiation and based on their attenuation one cannot precisely distinguish between bone, the magnesium’s degradation products (e.g. MgOH2) and metal, which makes proper degradation tracking impossible.
Syntellix developed non invasive routines to overcome these adverse and often inaccurate methods by combining H2-measurement and metal detection. Both methods are suitable to detect the state of degradation of magnesium implants in vivo directly or indirectly by means of periodically recurring standardized measurements. |
