What the Data Shows About Prosthesis, Hip, Semi-Constrained, Metal/Metal, Resurfacing

The FDA MAUDE database aggregates 6,864 adverse-event reports for Prosthesis, Hip, Semi-Constrained, Metal/Metal, Resurfacing spanning the period from 2004 through 2026. Of these, 18 are classified as death reports, 6,558 as injury reports, and 115 as malfunction reports under FDA adverse-event categorization rules. Report counts do not by themselves indicate a device is unsafe — widely used devices and longer market histories naturally generate larger raw counts, so proportional and comparative reads are more informative than totals alone.

The adverse-event profile breaks down across 5 distinct event types and 14 reported patient-outcome categories, giving a multi-dimensional view that goes beyond a single headline number. A total of 20 distinct product-problem codes appear in the reports, with Adverse Event Without Identified Device or Use Problem topping the list at 1,551 reports. Reports are associated with 10 different manufacturers in the MAUDE record, reflecting both OEMs and repackagers of this device category.

Annual reporting volume is tracked across 23 years of MAUDE data, with the peak single-year volume reaching 700 reports — trend shape often reflects changes in device adoption, reporting rules, or FDA enforcement focus rather than underlying device behavior alone. Events are documented across 7 reported care-setting categories (hospital, home, ambulatory surgery center, etc.). All figures reflect the openFDA MAUDE snapshot last refreshed on 2026-05-15.
