20 reports arrived in the 12 months to August 2026, down 51% from 41 in the 12 months before.

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 break (46.2%), device dislodged or dislocated (7.1%) and material deformation (7.1%). The patient problems coded most often are device embedded in tissue or plaque, pain and ambulation or postural difficulties. 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."
