223 medical device reports received by FDA name the brand "Viper2 Final Tightener Driver" (driver prosthesis); the manufacturer given most often on reports is Depuy Spine; received from January 2013 to July 2026. Brand names are as the reporter or manufacturer wrote them, so one product can appear under several spellings.

22 reports arrived in the 12 months to August 2026, down 49% from 43 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 (97.3%) and injury (2.7%); across all driver, prosthesis reports (product code HWR) death is recorded in 0% and malfunction in 97.5%. Event type is the reporter's classification of the report, not a verified outcome.

The patient problems coded most often are foreign body in patient, no patient involvement and injury. 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."
