It was reported that during an acl, after a twinfix was implanted into the bone and the surgeon pulled the shaft out of the body, the suture of the twinfix came off.The anchor remained in the bone.Surgery resumed after a non-significant delay of 5 minutes with a back-up device used in an additional bone hole.No further complications were reported.No further details available.

The reported device was received for evaluation.A visual inspection revealed that it is not in its original packaging.The insertion device was returned with the ultrabraid suture string off the device.No anchor was returned.There is biological debris on the returned items.A review of device records showed there were no indications to suggest that the product did not meet manufacturing specifications upon release for distribution.A complaint history review found similar reported events.The instructions for use were 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 and/or harm was documented appropriately, and there were no indications to suggest the anticipated risk is not adequate.A review of the blueprints found that no burrs, cracks or contamination is allowed.Also a statement (c of c) or evidence of conformance to material and processing specifications must be provided.A clinical review states that based on the limited information provided, the definitive clinical root cause of the reported adverse event could not be determined.The implantable anchor was retained in the patient¿s bone, therefore, micro-motion and/or migration of the retained anchor is unlikely.The patient's impact was the retained anchor, the additional bone hole, and the 5-minute surgical delay.Since no other complications were reported, no further clinical/medical assessment is warranted at this time.The root cause of the reported event could not be determined since findings cannot lead to a clear cause of the reported event.Factors that could have contributed to the failure 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.No containment or corrective actions are recommended at this time.
