FDA's MAUDE database holds 180 reports that name the brand "Unk - Nails" (rod fixation intramedullary and accessories), received between August 2019 and July 2026; the manufacturer given most often on reports is Synthes. Spellings of one product vary from report to report.

12 reports arrived in the 12 months to August 2026, down 14% from 14 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 (57.8%) and injury (42.2%); across all rod, fixation, intramedullary and accessories reports (product code HSB) death is recorded in 0.3% and malfunction in 33%.

The patient problems coded most often are nonunion/delayed-union bone fracture, failure of implant and pain. 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."
