FDA's MAUDE database holds 345 reports that name the brand "Summit Por Taper Sz4 Hi Off" (summit hip stem hip femoral stem), received between January 2009 and September 2025; the manufacturer given most often on reports is Depuy Orthopaedics US. Spellings of one product vary from report to report.

1 reports arrived in the 12 months to August 2026, down 67% from 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 (98.3%) and malfunction (1.7%); across all prosthesis, hip, semi-constrained, metal/polymer, porous uncemented reports (product code LPH) death is recorded in 0.2% and malfunction in 7.5%. 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 (29%), corroded (8.7%) and biocompatibility (5.5%). The patient problems coded most often are pain, test result and discomfort. 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."
