H3 device evaluation - both the screw and tulip were returned.Both parts were visually examined by eye prior to assembling.There are no signs of clamping on the bone screw sphere.The parts were able to be successfully assembled per the design intent and then the tulip and screw were simultaneously tugged on in an effort to disassemble.The parts do not exhibit any signs that they would be prone to disassembly.Review of device history records found (b)(4) pieces of this lot released for distribution on 3/7/2023 with no deviation or anomalies.Two-year complaint history review did not reveal a trend for reports of this nature for this part number.No corrective actions are being recommended since the parts appear to function per the design intent.However, it is unclear as to why the disassembly occurred.This report is number 1 of 2 mdrs filed for the same event (reference: 3005739886-2023-00036).
