Manufacturer Narrative

It was reported that on literature review "long-term blood metal ion levels and clinical outcome after birmingham hip arthroplasty, " five patients with bhr surgery had a revision surgery due to loosening of the femoral head.Further information is unknown and the devices, used in treatment, were not available for analysis.As no device part and batch numbers were provided for investigation, a complaint history review, manufacturing record review, device labelling / ifu review could not be performed.If more information is received, this investigation will be reopened.A review of historic escalation actions related to the products and similar complaint events was performed.Following the review, prior applicable escalation actions were identified and confirmed to reduce associated risks as far as possible.No further escalation actions are required.A risk management review was performed for the femoral head.The alleged failure modes and associated risks have been anticipated within the risk file and the anticipated risk level is still adequate.No further actions are required at this time.Without clinically relevant patient-specific supporting documentation, a thorough medical investigation could not be performed.The root cause and/or patient outcome beyond that which was documented in the article could not be confirmed nor concluded; therefore, no further medical assessment is warranted at this time.Without return of the actual devices or further information we cannot further investigate the details supplied in this complaint, our investigation remains inconclusive, and a definitive root cause cannot be determined.Based on the limited information provided we are unable to speculate on specific factors known to contribute to the alleged fault.If the products or additional information become available in the future, this case will be reopened.No preventative or corrective action has been initiated as a result of this investigation.Internal complaint reference number: (b)(4).
