FDA's MAUDE database holds 181 reports that name the brand "Distraction" (distraction), received between February 2018 and June 2026; the manufacturer given most often on reports is Karl Leibinger Medizintechnik & Kg. Spellings of one product vary from report to report.

13 reports arrived in the 12 months to August 2026, up 117% from 6 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 injury (93.4%) and malfunction (6.6%); across all external mandibular fixator and/or distractor reports (product code MQN) death is recorded in 0.2% and malfunction in 22.9%. Event type is the reporter's classification of the report, not a verified outcome.

The device problems coded most often are break (44.8%), osseointegration problem (7.2%) and detachment of device or device component (3.9%). The patient problems coded most often are impaired healing, inadequate osseointegration and device embedded in tissue or plaque. 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.
