Event Description

It was reported that, during thr surgery, the ref threaded hole cover went through to back of the shell, when it was inserted to the shell.The shell was retrieved to remove the hole cover, then, the shell was placed again with a back up hole cover.The surgeon used screws to assure the shell fixation and used the same screw holes to re-insert the shell in the acetabulum.Surgery was performed, after a a non significant delay, with a smith and nephew back up device.Patient was not harmed as consequence of this problem.

Manufacturer Narrative

H3, h6: the associated device was returned and evaluated.A visual inspection of the returned device did not confirm the stated failure mode.A dimensional inspection cannot be attempted, as the device is too damaged from the attempted insertion to obtain accurate measurements.A review of complaint history revealed similar events for the listed device over the previous 12 months, but no similar events for the batch based on the historical data, this failure mode will be monitored for future complaints for any necessary corrective actions.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 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.The contribution of the device to the reported event could not be corroborated.Possible probable cause could include but not limited to the user error during insertion.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.We consider this investigation closed.
