Area of Science:

  • Orthopedics
  • Neurosurgery
  • Trauma Surgery

Background:

  • The halo fixator is a medical device used for immobilizing the cervical spine.
  • It is employed in various clinical scenarios including trauma, deformity correction, and post-surgical stabilization.

Purpose of the Study:

  • To review the applications, efficacy, and safety of halo fixation in managing cervical spine conditions.
  • To highlight contraindications and potential complications associated with halo device usage.

Main Methods:

  • Review of existing literature on halo fixator applications and outcomes.
  • Analysis of reported efficacy in reducing cervical spine motion.
  • Identification of absolute and relative contraindications.
  • Summary of common and severe complications.

Main Results:

  • Halo fixation effectively reduces cervical motion (30%-96%).
  • Contraindications include cranial fractures, infections, severe soft-tissue injury, and relative concerns in elderly patients or those with specific chest morphologies.
  • Complications include pin loosening, infection, skin breakdown, and potentially life-threatening issues like respiratory distress in the elderly.
  • Pediatric use requires pre-placement CT scans to assess bone thickness.

Conclusions:

  • Halo fixation is a valuable treatment modality for specific cervical spine injuries and conditions.
  • Careful patient selection is crucial due to potential complications, particularly in vulnerable populations like the elderly.
  • Despite limitations, halo fixation demonstrates acceptable outcomes in managing certain upper and lower cervical spine injuries.
