FDA's MAUDE database holds 277 reports that name the brand "Open Implant Closure Top" (sequoia pedicle screw system including speedlink ii transverse connector system), received between November 2016 and September 2019; the manufacturer given most often on reports is Zimmer Biomet Spine. Spellings of one product vary from report to report.

0 reports arrived in the 12 months to August 2026, and none 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 (65.7%) and injury (34.3%); 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 fracture (44.8%), material deformation (43%) and break (5.4%). The patient problems coded most often are device embedded in tissue or plaque, foreign body in patient 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."
