Abstract

Magnesium alloys have been in the focus of research in recent years as degradable biomaterial The purpose of this study was the biomechanical characterisation of MgCa08screws The maximum pull out force of screws was determined in a synthetic bone without corrosion and after fixed intervals of corrosion 24 48 72 and 96 h This in vitro study has been carried out with Hank’s solution with a flow rate corresponding to the blood flow in natural bone A maximum pull out force Fmax of 2015 ± 93 N was measured without corrosion The biomechanical parameter decreased by 30 after 96 h in corrosive medium compared to the noncorrosion group A maximum load capacity of 28 ± 76 N/h was determined Our biomechanical data suggests that this biodegradable screw provides a promising bonescrewfixation and has great potential for medical application
