H10: h3, h6: the reported device was received for evaluation.There was a relationship found between the device and the reported event.A complaint history review found similar reported events.A review of device records showed there were no indications to suggest that the product did not meet manufacturing specification upon release for distribution.The instructions for use was reviewed and found to include conditions of off label use and technique specifics, as well as precautions and warnings related to the use of the device.A risk management review found that the reported failure was documented appropriately, and there were no indications to suggest the anticipated risk is not adequate.A review of the polymer found that the storage requirements, material specifications, and applicable tests were appropriately specified.A material certificate of analysis was required for the raw material.A review of the customer provided image found labelling confirming the product identification information.The anchor is on the shaft of the device, but the condition of the device cannot be determined from the image.A visual inspection of the returned device found that it is not in its original packaging.The anchor is on the shaft of the device, and there is a fracture in the threads.When the anchor is removed from the device, the sutures had been cut, and the prongs on the distal end of the shaft was deformed.There is debris on the device.Based on the condition of the product material found during visual inspection, additional material testing is not required.A functional evaluation could not be performed due to the condition in which the device was received.The fracture in the anchor could affect the ability of the device to be secured properly within the insertion site.If any fractured pieces were retained the twinfix anchor is implantable, biocompatibility is not an issue.It is unknown if the possible retained fragments will migrate and there is potential risk for tissue inflammation and/or pain.No further clinical/medical assessment is warranted at this time.The complaint was confirmed, and the root cause was associated with unintended use of the device.Factors that could have contributed to the reported event include excessive force on the device, excessive torque on the device, attempted correction of a damaged device, off-axis insertion, improper preparation of the insertion site, or an inadvertent impact event inconsistent with normal use.Please refer to the instructions for use for recommendations on proper use of the device and potential troubleshooting methods to prevent future reoccurrence of the reported event.No containment or corrective actions are recommended at this time.
