430 medical device reports received by FDA name the brand "Ti Low Profile Neuro Screw Self-Drilling 4mm" (bone plate); the manufacturer given most often on reports is Oberdorf Synthes Produktions; received from September 2011 to October 2025. Brand names are as the reporter or manufacturer wrote them, so one product can appear under several spellings.

4 reports arrived in the 12 months to August 2026, down 89% from 37 in the 12 months before. FDA releases MAUDE data monthly; reports can arrive months after an event, so the newest months grow in later releases. The event types recorded are malfunction (71.9%) and injury (28.1%); across all plate, bone reports (product code JEY) death is recorded in 0.2% and malfunction in 48.8%. Event type is the reporter's classification of the report, not a verified outcome.

The device problems coded most often are break (56.7%), material deformation (10.7%) and material twisted/bent (7.4%). The patient problems coded most often are infiltration into tissue, rupture and confusion/ disorientation. FDA states that "MDR data alone cannot be used to establish rates of events, evaluate a change in event rates over time or compare event rates between devices. The number of reports cannot be interpreted or used in isolation to reach conclusions about the existence, severity, or frequency of problems associated with devices." It adds that the reporting system "has limitations, including the potential submission of incomplete, inaccurate, untimely, unverified, or biased data."
