Manufacturer Narrative

The device, used in treatment, was not returned for evaluation and the reported event could not be confirmed.The clinical / medical investigation concluded that, reportedly the pain and revision were due to dislocation of the right hip while bending over donning the right shoe.The clinical root cause of the reported dislocation could not be definitively concluded; however, the mixed manufacturer right hip-construct, history of prior right hip dislocation/revision approximately 8 weeks ago, and the patient activity could not be ruled out as a possible contributing factors to the reported events.Of note, the patient does have a contralateral history of revisions x 3 due to dislocations, one notably in 10/2015 during an attempt to don socks.It could not be concluded that the reported clinical findings were associated with a mal-performance of the s+n implants used in the mixed-manufacturer-construct.Patient impact assessed was the dislocation, subsequent pain, ambulation difficulties, and revision which included exploration of the sciatic nerve due to continued foot-drop.Further patient impact could not be determined.A review of complaint history did not reveal additional complaints for the listed batch.A review of the manufacturing records did not reveal a manufacturing abnormality that could have caused or contributed to the reported incident.A review of the risk management file and instructions for use documents revealed this failure mode was previously identified.At this time, we have no reason to suspect that the product failed to meet any product specifications at the time of manufacture.Possible causes could include but not limited to traumatic injury, patient anatomy or abnormal loading of limb.Based on this investigation, the need for corrective action is not indicated.Should the device or 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.
