Fractures are a complication of distraction osteogenesis, occurring at 9.4% in lengthened segments. Treatment depends on fracture location and patient factors, with internal fixation often preferred for displaced fractures.

Area of Science:

  • Orthopedic Surgery
  • Regenerative Medicine

Background:

  • Distraction osteogenesis is a surgical technique to lengthen bone segments.
  • Fractures can occur as a complication during or after this procedure.

Purpose of the Study:

  • To determine the incidence, location, and timing of fractures during distraction osteogenesis.
  • To analyze the factors influencing fracture management in this context.

Main Methods:

  • Retrospective review of 173 patients undergoing distraction osteogenesis.
  • Analysis of fracture incidence, location (regenerate, junction, distant), and timing.

Main Results:

  • An overall fracture rate of 9.4% was observed in 180 lengthened segments.
  • Fractures varied in location: 6 in regenerate, 6 at regenerate-bone junction, 5 distant.

  • Five regenerate fractures were linked to compression and collapse; three cases showed gradual collapse post-frame removal.

    • Conclusions:

    • Fracture management in distraction osteogenesis requires specific considerations beyond acute trauma.
    • Internal fixation is suitable for displaced fractures; external fixation may be needed for specific cases (e.g., infection).
    • Intramedullary nailing carries an infection risk; plate fixation is safe for displaced, unstable pediatric fractures.
