FDA's MAUDE database holds 182 reports that name the brand "Delta Cer Head 12/14 32mm +9" (articuleze head 12/14 taper hip ceramic femoral heads), received between January 2011 and December 2025; the manufacturer given most often on reports is Depuy Orthopaedics US. Spellings of one product vary from report to report.

6 reports arrived in the 12 months to August 2026, down 45% 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 injury (95.1%), malfunction (4.4%) and death (0.5%); across all prosthesis, hip, semi-constrained, metal/ceramic/polymer, cemented or non-porous, uncemented reports (product code LZO) death is recorded in 0.2% and malfunction in 9.1%. Event type is the reporter's classification of the report, not a verified outcome.

The device problems coded most often are device dislodged or dislocated (33.5%), insufficient device problem information (7.1%) and naturally worn (4.4%). The patient problems coded most often are joint dislocation, pain and joint laxity. 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."
