954 medical device reports received by FDA name the brand "Pinnacle Mtl Ins Neut40idx58od" (pinnacle hip system hip metal acetabular liners); the manufacturer given most often on reports is Depuy Orthopaedics US; received from January 2009 to December 2024. 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 (95.6%), malfunction (4.1%) and death (0.3%); across all prosthesis, hip, semi-constrained (metal uncemented acetabular component) reports (product code KWA) death is recorded in 0.3% and malfunction in 3.4%. 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 (64.3%), naturally worn (35.3%) and metal shedding debris (11.3%). 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."
