388 medical device reports received by FDA name the brand "Cd Horizon" (appliance fixation spinal interlaminal); the manufacturer given most often on reports is Mdt Sofamor Danek Puerto Rico Mfg; received from January 2011 to August 2026. Brand names are as the reporter or manufacturer wrote them, so one product can appear under several spellings.

38 reports arrived in the 12 months to August 2026, up 660% from 5 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 (50.5%), injury (49%) and death (0.3%); across all appliance, fixation, spinal interlaminal reports (product code KWP) death is recorded in 0.3% and malfunction in 46.2%. Event type is the reporter's classification of the report, not a verified outcome.

The device problems coded most often are break (24.5%), migration or expulsion of device (15.5%) and device slipped (13.1%). The patient problems coded most often are pain, device embedded in tissue or plaque 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."

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.
