FDA's MAUDE database holds 210 reports that name the brand "Trident Hemispherical Cluster Hole Shell" (implant), received between January 2005 and December 2023; the manufacturer given most often on reports is Stryker Orthopaedics-Mahwah. 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 (84.8%), malfunction (14.3%) and other (1%); across all prosthesis, hip, semi-constrained, uncemented, metal / polymer, non-porous, calcium phosphate reports (product code MEH) death is recorded in 0.1% and malfunction in 10.5%. 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 (23.3%), device dislodged or dislocated (9%) and device slipped (9%). The patient problems coded most often are injury, pain and inadequate osseointegration. 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."
