Corrected information: the manufacturer was incorrectly listed on the original submission.This information has been corrected on this follow up report.Visual evaluation of the received devices show no abnormalities or damage.Under certain basic conditions a risk of rotational instability could be possible.Problematic bone situation.Rotation of the rasp during application.Meanwhile modified rasps are available for use.These rasps have additional cross teeth in the approximal area which support intra operative stability.The device quality and manufacturing history records were reviewed for the available lot numbers and were found to be according to specification valid at the time of production.Based on the information available as well as a result of the investigation, the root cause of the failure is not product or design related.So far there are (b)(4) complaints with this failure.These products have been sold since 2014 and are therefore quite new.The design was tested.If this device (old design) is applied properly, this failure should not occur.Corrective/preventive action is not required.
