Manufacturer Narrative

Results of investigation: it was reported that during a total hip replacement procedure, a problem has been detected regarding packaging with loss of sterility.The last peel bag of a polarstem stem lat.Ti/ha 2 non-cem was opened in the distal part.The claimed article, which intent use is in treatment, including damaged packaging was not returned for investigation.On picture was provided.The picture shows the polarstem stem in the innermost bag.There are traces of blood on the label.Another bag is lying next to it.It appears that the innermost bag has been opened at the seams sealed for this purpose.According to the complaint description, the last plastic bag of this stem was opened in the distal part.According to the picture given this statement can not be confirmed.In order to be able to make a statement on the basis of pictures, these must show the problem in more detail.Ideally, the claimed packaging should be returned for detailed examination.A product history review reveal no deviations that could explain the occurred failure.Without the specific article including packaging or more detailed pictures the reported failure can not be confirmed and the root cause remains undetermined.Repeated stock manipulations may have contributed to the motion of the stem inside the packaging causing the observed sterility breach.According to our instructions for use (ifu lit.No.12.23 ed.05/16) implants may not be implanted under any circumstances if the packaging is damaged or not intact.Peel pouches showing scratches or significant migration of the stem towards the sealed seams as well as stems observed to move freely inside the peel pouches or should therefore be considered as unfit for use.If this scenario occurs, we kindly ask you to return the affected products (the peel pouches and the corresponding stems) to the appropriate smith & nephew representative or office for investigation.This complaint will be closed.Smith&nephew will however continue to monitor the corresponding products for similar issues.
