FDA's MAUDE database holds 549 reports that name the brand "Biolox Delta Hip" (head femoral ceramic bilox delta 36mm neutral), received between May 2017 and November 2023; the manufacturer given most often on reports is Encore Medical L P. Spellings of one product vary from report to report.

0 reports arrived in the 12 months to August 2026, and none 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 (100%); 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 (32.4%), unstable (4.7%) and insufficient device problem information (1.5%). The patient problems coded most often are joint dislocation, failure of implant and fall. 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."
