1,157 medical device reports received by FDA name the brand "Quickset Ace Grater Head 55mm" (hip instruments reamers); the manufacturer given most often on reports is Depuy Orthopaedics US; received from June 2015 to February 2026. Brand names are as the reporter or manufacturer wrote them, so one product can appear under several spellings.

10 reports arrived in the 12 months to August 2026, down 80% from 49 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 (100%); across all reamer reports (product code HTO) death is recorded in 0% and malfunction in 95.7%. Event type is the reporter's classification of the report, not a verified outcome.

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."
