ABSTRACT:
In-Vitro Degradation of Fe-28Mn Absorbable Bone Plate
Magnesium, iron, and zinc base alloys have been investigated for absorbable implants which are designed to degrade in the body (in-vivo) as a result of controlled corrosion reactions. Degradation products should be transported and eliminated without local or systemic accumulation in the body. Implant degradation must be balanced against mechanical integrity to achieve functionality over a specified timeframe.
Absorbable alloys have been extensively researched over the years for cardiovascular implants. Absorbable stents appear to be a promising application due to their small size (<2 mm O.D.). However, other researchers have begun to investigate the degradation properties of larger implants. The present research was initiated to characterize the degradation rate of small Fe-28Mn bone plates after 3, 6, and 12 months immersion in phosphate buffered saline (PBS). Four-point bend testing was performed before and after PBS immersion and weight loss was recorded.
Test results and research observations will be presented. Various factors while be analyzed to explain the degradation reactions and the mechanical results that were obtained.
