H3, h6: it was reported that a hip revision surgery was performed due to metallosis with a big pseudotumor.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 investigation, a complaint history review, manufacturing record review, device labelling / ifu, or escalation actions review could not be performed.If more information is received, this investigation will be reopened.A risk management review was performed for the acetabular cup.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.No relevant supporting clinical information has been provided to assist with a clinical investigation.Without the requested clinical information, a thorough medical investigation cannot be rendered.It should be noted that the implant remained in situ for 12 years.It cannot be concluded that the reported issue was caused by a mal function of the components.The patient's current condition is unknown.With the information provided, the impact to the patient beyond the surgery and recovery cannot be determined.Should any additional clinical information be provided, this complaint will be re-evaluated.Based on the information provided we cannot confirm or further investigate the reported complaint, our investigation remains inconclusive, and a definitive root cause cannot be determined.Specific factors known to contribute to the alleged fault are excessive physical activity levels, unreasonable stress on replacement system, excessive patient weight, trauma to the joint replacement, loosening of components may increase production of wear particles and accelerate damage to the bone.Should the devices or additional information be received, the complaint will be reopened.Based on this investigation, the need for corrective and preventative actions is not indicated.Internal complaint reference number: (b)(4).
