Manufacturer Narrative

(b)(4).Updated: b1, b4, b5, g3, h1, h2, h3, h6, h10.Complaint was confirmed by visual examination of the returned product which identified that there is extensive damage to the stem in terms of scratches and taper damage.The inserter is missing the spring that holds tension to the rod that holds the stem.The set screw that holds the spring into place in the inserter was loose and does not show any signs of the epoxy anymore.Inside the inserter where the set screw is installed does not show any signs of epoxy as well.The inserter was manufactured in may of 2018.The stem and the inserter do mate as intended but the trigger had to be pushed towards the stem since the spring is missing.Device history record was reviewed and no discrepancies relevant to the reported event were found.The root cause of the reported issue is attributed to user error as the spring was missing from the inserter causing it to not function.This should have been identified prior to the procedure and/or during reprocessing.If any further information is found which would change or alter any conclusions or information, a supplemental will be filed accordingly.Zimmer biomet will continue to monitor for trends.
