The device was returned for review and a hair was found sitting in the concave surface of the liner.The device history record was reviewed and the documentation indicated that all devices of that lot were manufactured and packaged to specifications.There were no deviations to the standard manufacturing process associated with this review.No additional complaints have been received against this manufacturing lot.Although foreign material could be introduced during the packaging process, zimmer takes several measures to prevent this from occurring.This device was packaged in a class 10,000 clean room, under a specially designed hooded packaging station that creates a class 1000 clean room environment that significantly reduces the presence of foreign contaminants.Personnel in the clean room are required to wear items such as hair nets, protective clothing and booties, to reduce the likelihood of foreign materials from being introduced during the packaging process.In addition, single-use, sterilized devices manufactured or distributed by zimmer are sterilized in accordance with fda regulations and iso standards to a sterility assurance level of 1.0 x 10-6 or better.Therefore, it is highly unlikely that the presence of the hair found in the packaging would have led to any infections or other bio-incompatibility if it had been used.With the information provided, the origin of the hair cannot be determined and thus a root cause cannot be stated.
