Manufacturer Narrative

H3: product analysis part# g3002041 ; lot# 0834892w- visual and optical inspection revealed that the plate has extensive damage to the lower right hole, along with a screw whose damage matched up with that of the hole.Damage inside the star locks of the plate is consistent with tightening/untightening of the pieces, but no damage was found on the underside of the lock that was responsible for holding in the backed out screw.Thus, it seems as if the lock was in the process of being tightened, but never was.H6: updated eval.Code method and eval.Code result post analysis medtronic submits this report to comply with fda regulations 21 cfr parts 4 and 803.Medtronic has made reasonable efforts to provide as much relevant information as is available to the company as of the submission date of this report.This report does not constitute an admission or a conclusion by fda, medtronic, or its employees that the device, medtronic, or its employee caused or contributed to the event described in the report.Any required fields that are unpopulated are blank because the information is currently unknown or unavailable.Medtronic will submit a supplemental report if additional relevant information becomes known.
