Spellings of one product vary from report to report.

3 reports arrived in the 12 months to August 2026, down 88% from 25 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 (62.2%) and injury (37.8%); across all thoracolumbosacral pedicle screw system reports (product code NKB) death is recorded in 0.3% and malfunction in 41.2%. Event type is the reporter's classification of the report, not a verified outcome.

The device problems coded most often are material twisted/bent (27.1%), device-device incompatibility (13.9%) and break (10.1%). The patient problems coded most often are neurological deficit/dysfunction, paralysis and no patient involvement. 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."

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.
