154 medical device reports received by FDA name the brand "R3 Depth Gauge" (appliance fixation nail/blade/plate combination multiple component); the manufacturer given most often on reports is Smith & Nephew; received from February 2019 to August 2026. Brand names are as the reporter or manufacturer wrote them, so one product can appear under several spellings.

12 reports arrived in the 12 months to August 2026, down 37% from 19 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 malfunction (84.4%) and injury (15.6%); across all appliance, fixation, nail/blade/plate combination, multiple component reports (product code KTT) death is recorded in 0.3% and malfunction in 29.1%. Event type is the reporter's classification of the report, not a verified outcome.

The device problems coded most often are break (53.9%), fracture (35.7%) and material twisted/bent (3.9%). The patient problems coded most often are no patient involvement and failure of implant. 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."

Where this comes from. Counts are built from the openFDA Device Adverse Event (MAUDE) bulk export released 28 Sep 2026, which holds reports FDA received through 31 Aug 2026. Brand, generic and manufacturer names are as written on the reports; product code names come from FDA's device classification. A report counts here when any device it lists carries this brand name after punctuation and capitalisation are normalised. No report narrative, lot number, patient detail or reporter identity is published. See the methodology and sources; FDA's record is authoritative, and corrections are handled within five working days.
