Manufacturer Narrative

By checking the sterilization charts of the involved products, no pre-existing anomalies were found thus we can state that all the components had been regularly sterilized before being placed on the market.Explants analysis: explanted component not available for further analysis.Complaint source reported that patient was biopsied and grew 2 different staphs on 2 different specimens.We received some pictures of the explants.X-rays analysis: we received some pre-op revision x-rays dated (b)(6) 2020.We asked for a clinical opinion about the case to our medical consultant.Following his statement: "we have no information on comorbidities so assume there are none.The 2 different staph species confound things and a definite diagnosis of infection cannot be made.We do not have any other data available that would assist us further.This patient has had pain from the outset and this feature has been recognised on our registry as "pain from no obvious cause" which we now suspect in most cases is "occult infection".I do not see any obvious features on the x rays that would be consistent with infection.The metal back baseplate is significantly "too high" and there is impingement as a consequence.There is no hard data that correlates impingement with infection but again we are suspicious of that possibility.The surgeon will have information available that would allow better judgement on the appropriateness or otherwise of the decision to bone graft, but if overt infection was present conventional wisdom would be not to do that.In summary a likely low grade infection has occurred from the time of the index procedure, ie this is an early surgery related (and not blood borne infection).The base plate is too high and while this is surgeon error there is no data that supports this being associated with infection" stating that: no pre-existing anomalies were found by checking the sterilization charts of the involved products; the medical consultant highlighted that ".The base plate is too high and while this is surgeon error there is no data that supports this being associated with infection" no specific root cause can be assigned to this case.Based on the investigation performed we cannot classify this event as product related.Pms data: revision rate related to infection of smr reverse prosthesis is 0.06%.No specific corrective actions for this case.Limacorporate will continue monitoring the market to promptly detect any further similar issue.Note: this is a final mdr.
