Manufacturer Narrative

H3, h6: the associated device was returned and evaluated.The manufacturing process of the device did not contribute to the reported event.A visual inspection of the returned device could not confirm the stated failure mode.The device is severely worn from use.A review of complaint history did not reveal similar events for the listed device.The clinical/medical evaluation concluded that a review of the provided x-rays confirmed osteolysis behind the shell.Also, it was noted that the head isn¿t centered.So there may be poly wear.No further clinical documentation was provided.Therefore, based on the information provided, the clinical root cause of the reported osteolysis cannot be confirmed.The patient impact beyond the revision cannot be determined.Should any additional relevant clinical information be provided, this complaint would be re-assessed.A review of the manufacturing records did not reveal a manufacturing abnormality that could have caused or contributed to the reported incident.At this time, we do not have reason to suspect that the product failed to meet any product specifications at the time of manufacture.A review of the risk management file and instructions for use document revealed this failure mode was previously identified.The anticipated risk level is still adequate.Assessment of historical escalated cases concluded that there are no prior actions related to this device and failure mode.Wear potential causes could include but are not limited to friction, joint tightness or lifetime of device.Based on this investigation, the need for corrective action is not indicated.Should additional information be received, the complaint will be reopened.No further investigation is warranted for this complaint; however, we will continue to monitor future complaints and investigate as necessary.
