Manufacturer Narrative

H3, h6: it was reported that, after a primary left bhr tha surgery performed, the plaintiff experienced ringing in his ears, tremor, severe pain, and evidence of osteolysis in the acetabulum, so so a left hip revision surgery was performed.The devices, used in treatment, were not returned for evaluation.A review of the complaint history for the head cup and sleeve was performed using batch numbers in search of similar recurring reports for the products during their lifetimes and using part numbers and the reported failure modes to evaluate patterns of repeated failures or defects in a timeframe prior 12 months as of the complaint reopen date.Similar complaints have been identified for the cup and failure mode and this will continue to be monitored through routine complaint trending.In the absence of the actual devices, the production records were reviewed for the devices reportedly involved in this incident.All the released devices involved met manufacturing specifications at the time of production.Review of the product ifu found adequate warnings and precautions in relation to the alleged failure modes.A risk management review was performed.No additional risks were identified as result of the reported event.The alleged failure modes and associated risks have been anticipated within the risk file and the anticipated risk level is still adequate.A review of historic capa/nc/pra/hhe/field 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.The available medical documents were reviewed.With the limited information provided the clinical root cause of the reported ringing in his ears, tremor, severe pain, and metallosis cannot be confirmed.It cannot be concluded the reported events / clinical reactions were associated with a mal performance of the implant or implant failure.The patient impact beyond the reported events cannot be determined based on the information provided we cannot further investigate the 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.If the products or additional information become available in the future, this case will be reopened.Based on this investigation the need for corrective and preventative action is not indicated.
