Manufacturer Narrative

Investigation: by checking the dhr of the lot numbers 19aq1t4, 18aq1bm, 18aq13e, and 19aq1t5 no pre-existing anomalies were detected on all the components manufactured with these lot numbers.Instrument analysis: only the explants were available to be returned to hq for further analysis.According to the information received by the complaint source, the inability to break the taper between the baseplate and connector, causing the extractors to break and increase the case time was the only complaint that was made.The internal inspections of the explants highlighted that the most likely cause of the breakage is the presence of fretting between the parts connected that could have caused the difficulty in disengagement.Therefore, since: 1.No anomalies were found out by checking the manufacturing charts of the lot numbers involved, and.2.The internal analysis led to the identification of fretting as the as the most likely cause of the breakage of the instruments, we can suppose that the event could not be due to inherent problems of the products.Pms data: according to our pms data, we can estimate the breakage rate of the instrument smr - glenosphere extractor to be around 0,19% (ww).Please note that this occurrence rate is overestimated because it does not consider the reuse of the instruments but only the total number of pieces manufactured.Based on the 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.This is a final mdr.
