Manufacturer Narrative
|
Additional narrative: a manufacturing evaluation was completed: the device was received with the tip of the screw broken off.The relevant dimension of the screw was checked and found to be in compliance with the technical drawings and ao/asif specification.The examination of the raw-material testing certificate and the manufacturing papers showed no deviations regarding material analysis, strength and structural stability.The values were in compliance with ao/asif specification and with the international standard iso 5832-1.The fracture face is homogenous, which indicates material conformity and has the typical view of a forced rupture.No product fault could be detected.This lot was manufactured in september 2013.We are not able to determine the exact cause of this occurrence.It is likely that a mechanical overload, par example by an exceptional hard bone, caused this breakage.Device was used for treatment, not diagnosis.If information is obtained that was not available for the initial medwatch, a follow-up medwatch will be filed as appropriate.
