Manufacturer Narrative

Results of investigation: the associated device was returned and evaluated.The visual inspection revealed the screw holes are stripped.A dimensional evaluation performed on the device revealed compliance with the specified tolerances.It is evident that the damage to the star tab likely occurred during the insertion or extraction of the locking screw on several hole locations.The possibility exists that incorrect screw placement or excessive torque caused the damage, leading to the complete loss of star tabs.In conclusion, the damage to the star tab and hole did not originate during the part's machining process.A review of the production order did not reveal a manufacturing abnormality that could have caused or contributed to the reported incident.A review of complaint history revealed a similar event 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 instructions for use documents for evos¿ plating system revealed that it is extremely important to select the appropriate size and type components.Failure to use the largest possible components or improper positioning may result in loosening, bending, cracking, or fracture of the device or bone or both as a warning.A review of the risk management file revealed this failure mode was previously identified.The anticipated risk level is still adequate.A historical review concluded that there are no prior actions related to this product and event.At this time, we have no evidence to conclude that the product failed to meet specifications at the time of manufacture.Factors that could contribute to the reported event include surgical technique used or user/procedural variance.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 for future complaints and investigate as necessary.We consider this investigation closed.
