764 medical device reports received by FDA name the brand "12/14 Articul 40mm M Spec+5" (articuleze head 12/14 taper hip metal femoral heads); the manufacturer given most often on reports is Depuy Orthopaedics US; received from January 2009 to August 2025. Brand names are as the reporter or manufacturer wrote them, so one product can appear under several spellings.
0 reports arrived in the 12 months to August 2026, against 3 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 (96.7%) and malfunction (3.3%); across all prosthesis, hip, semi-constrained, metal/polymer, cemented reports (product code JDI) death is recorded in 0.4% and malfunction in 7.8%. Event type is the reporter's classification of the report, not a verified outcome.
The device problems coded most often are insufficient device problem information (57.6%), naturally worn (30.5%) and device dislodged or dislocated (9.7%). The patient problems coded most often are pain, discomfort and foreign body reaction. 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."
