Manufacturer Narrative

H3,h6: it was reported that the patient experienced unspecified symptoms that required a revision surgery.As of today, the implanted devices, all of which were used in treatment have not been returned for evaluation.As no device part and batch numbers were provided for the modular sleeve, a complaint history review could not be performed.Without a definitive batch number, a complete review of the historical complaints data cannot be performed for the hemi head.A review of historical complaints data was performed using the part number and the reported failure modes to evaluate patterns of repeated failures or defects.Similar complaints were identified for the hemi head, however, as the device is no longer sold, no action is to be taken.As no device batch numbers were provided for investigation for the devices concerned, a manufacturing record review, device labelling / ifu review could not be performed.If more information is received, this investigation will be reopened.Without details of the type of symptoms experienced by the patient, it is not possible to evaluate the risk file for the devices.Therefore, a risk management review was not performed.Should further details become available at a later date then the task will be reopened and completed.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 required.Smith and nephew has not received the explanted device and/or adequate materials to fully evaluate the complaint from a clinical perspective.Without additional information we cannot further investigate or confirm the reported complaint.The 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.
