Manufacturer Narrative

(b)(4).Reported event was confirmed as review of the available records identified a orif distal humeral fracture complicated by proximal screw loosening and fracture non-union.Subsequent orif revision with subsequent plate retraction and extensive screw loosening with persistent non-union.Extensive screw loosening of both the original humeral orif and subsequent revision with fracture non-union and malalignment as described.Initial bone quality was mildly osteopenic with marked progression over time to severe osteopenia.Device history record (dhr) review was unable to be performed as the lot number of the device involved in the event is unknown.A definitive root cause could not be determined.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.
