316 medical device reports received by FDA name the brand "Twinfix Ultra Ha 4 5 W/2 Ub Wh & Blue" (fastener fixation biodegradable soft tissue); the manufacturer given most often on reports is Smith & Nephew; received from March 2018 to August 2026. Brand names are as the reporter or manufacturer wrote them, so one product can appear under several spellings.

56 reports arrived in the 12 months to August 2026, up 60% from 35 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 (62.7%) and injury (37.3%); across all fastener, fixation, biodegradable, soft tissue reports (product code MAI) death is recorded in 0% and malfunction in 73.8%. Event type is the reporter's classification of the report, not a verified outcome.

The device problems coded most often are break (74.4%), fracture (12.3%) and material separation (6.3%). The patient problems coded most often are foreign body in patient, perforation and device embedded in tissue or plaque. 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."
