By the check of the device history records, no pre-existing anomaly was detected on the cups released with lot number 1413046 and on the stems released with lot number 1407845.This is the first and only complaint registered on these lot numbers.The following x-rays were provided by the complaint source: - x-rays taken before initial surgery, dated (b)(6) 2014 - x-rays taken after the initial surgery, dated (b)(6) 2015, (b)(6) 2016, (b)(6) 2017, (b)(6) 2019, (b)(6) 2022 - x-rays taken after the revision surgery, dated (b)(6) 2023.The x-rays and available information were analyzed by a medical consultant, he commented: "loosening of the cemented components is evident.I do not see any sign of polyethylene wear but debris and osteolysis may be present due to high rate of cement particles ("cement-disease").Are you sure there has not been additional surgery in 2016? the amount of x-rays raises some doubt and on one i see a an element that might be identified as a palacos bead, indicating some revision (dair) because of infection? the last revision has been done appropriately, given no additional infection has been present." the complaint source reported that a surgery was performed on (b)(6) 2016, but it was not a revision surgery ("stem puncture").The involved devices were not returned, therefore no specific analysis could be performed on them.On the basis of the available information, we cannot determine the cause of the loosening reported.The check of the device history records confirmed the involved lot numbers were manufactured up to specifications and in line with the relevant checks and tests.This event is classified as not product related.Pms data according to limacorporate pms data, the revision rate of cemented cups (family codes 5615/16/18/19/20/22/26.50.Xxx) due to dislocation and/or loosening is about (b)(4).No other revision surgery due to loosening of cemented sl stems belonging to family codes 3515.05.Xxx is registered in our systems (specific revision rate lower than (b)(4)).No corrective actions required for this specific case.Limacorporate will continue monitoring the market to promptly detect any further similar event.
