The associated reflection 3 hole shell was not returned for evaluation.Therefore, a product analysis could not be conducted.However, our investigation indicated that this failure has been previously identified.A quality hold was placed in an attempt to quarantine and re-inspect additional products for this failure mode.During the investigation, it was found that screw hole was damaged during the manual deburr operation.Consequently, corrective actions have been implemented to prevent recurrence of this failure mode.Our clinical evaluation noted that with the limited clinical details, no medical assessment can be rendered at this time.The patient impact beyond the potential screw migration, expected revision procedure/post-op rehab, possible additional radiological exposure and possible continued migration cannot be concluded.Without the return of the actual product involved, our investigation of this report is inconclusive.No further investigation warranted for this complaint; however smith and nephew will continue to monitor for future complaints and investigate as necessary.Should the device or additional information be received, the complaint will be reopened.We consider this investigation closed.
