199 medical device reports received by FDA name the brand "Unknown T2 Alpha Tibia Nail" (rod fixation intramedullary and accessories); the manufacturer given most often on reports is Stryker; received from November 2020 to October 2025. Brand names are as the reporter or manufacturer wrote them, so one product can appear under several spellings.
175 reports arrived in the 12 months to August 2026, up 17400% from 1 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 injury (100%); across all rod, fixation, intramedullary and accessories reports (product code HSB) death is recorded in 0.3% and malfunction in 33%. Event type is the reporter's classification of the report, not a verified outcome.
The device problems coded most often are migration (3%), fracture (2%) and structural problem (2%). The patient problems coded most often are pain, nonunion/delayed-union bone fracture and wound infection. 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."
