310 medical device reports received by FDA name the brand "Duraloc Curved Cup Impactor" (hip instruments impactors); the manufacturer given most often on reports is Depuy Orthopaedics US; received from January 2015 to March 2026. Brand names are as the reporter or manufacturer wrote them, so one product can appear under several spellings.

19 reports arrived in the 12 months to August 2026, up 73% from 11 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 impactor reports (product code HWA) death is recorded in 0% and malfunction in 98%.

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."
