Manufacturer Narrative

By checking the sterilization charts of the involved lot #s, no pre-existing anomaly was found on the overall number.All the products placed on the market with these lot #s have been properly sterilized before being placed on the market.Explanted items were not available to be returned to limacorporate for further analysis.X-rays analysis: limacorporate received a total of two x-rays referring to pre-operative revision surgery.The x-rays received - dated (b)(6) 2021 - have been evaluated by a medical consultant.Following, the medical consultant comments: "the index surgery was for a fracture so we cannot criticize selection of the patient with serious co-morbidities (which i am assuming).The xray is terrible! it shows some fragments of bone which i assume are tuberosities because the humeral body has no adjacent bone.I am guessing that these tuberosities were not reattached which if so would be an error but would not prevent infection.The loosening may well be entirely due to infection but infection does not necessarily go onto macroscopic failure of the glenoid complex.In summary: in a patient with co-morbidities that might compromise immune status "patient factors" have to be a significant contributor to the early post operative infection.If the tuberosities were not reattached i would be critical of that but that would not prevent the failure of fixation of the glenoid".Considering that: · check of sterilization charts highlighted no anomalies on the total number of components manufactured with the involved lot #s; · according to the medical consultant, "in a patient with co-morbidities that might compromise immune status "patient factors" have to be a significant contributor to the early post operative infection"; we can state that the event was not product related.Pms data: according to limacorporate pms data, revision rate of smr reverse prosthesis due to infection is (b)(4).Based on the root cause analysis performed and according to the relevant pms data, no corrective actions required for this specific case.Limacorporate will continue monitoring the market to promptly detect any further similar issue.Note: this is a final mdr.
