It was reported that, after a bhr surgery had been performed around 16 years ago, the resurfacing head loosened.A revision surgery was performed to address this event.Intraoperatively, some bone loss in the neck was noted.Both components were explanted to convert to a tha with an r3-anthology system.The devices, used in treatment, were not returned 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.Smith and nephew has not received the explanted device and/or adequate materials to fully evaluate the complaint from a clinical perspective.If additional clinically relevant materials are later received, then the case may be re-opened for further evaluation.Without additional information we cannot further investigate or confirm the reported complaint.The investigation remains inconclusive, and a definitive root cause cannot be determined.Additionally, specific factors known to contribute to the alleged fault cannot be provided due to the insufficient information.If the products or additional information become available in the future, this case will be reopened.Based on this investigation, the need for corrective or preventative action is not indicated.
