The associated reflection liner and cobalt chrome femoral head were not returned for evaluation.Therefore a product analysis could not be performed.After repeated requests, smith and nephew has been unable to obtain device details.As device details were not made available, device history record cannot be completed.Complaint history review could not be performed with any accuracy due to lack of batch number.Our investigation including a clinical evaluation noted that the root cause of the peri-prosthetic fracture could not be determined based solely on the one x-ray image provided; however, the approximate 20.5 years in vivo, probable wear particles and impingement with the liner, and declining bone quality were likely contributing factors to the reported event as profound rim poly wear was demonstrated on the explant photos.The patient impact beyond the revision procedure and an expected brief post-operative rehab phase could not be concluded.There is no information that would suggest the implanted devices failed to meet specifications.A relationship, if any, between the devices and the reported incident or adverse event could not be corroborated.Without the return of the actual product involved and batch information available, our investigation of this report is inconclusive.No further investigation is warranted for this complaint; however, smith and nephew will continue to monitor for future complaints and investigate as necessary.Should the device or additional information be received, this complaint will be reopened and reevaluated.
