AI Article Synopsis

  • Direct surgical C2 pedicle screw fixation is presented as a treatment for acute complex C2 vertebral body fractures, avoiding complications associated with traditional methods.
  • Three patients underwent this procedure with successful outcomes, demonstrating immediate stability and no neurological injuries.
  • Follow-up revealed good screw placement, fracture alignment, and overall recovery with no significant disability reported at one year, suggesting this method might be preferable to external stabilization options.

Article Abstract

Background: Acute complex C2 vertebral body fracture specifically does not involve the odontoid process or C2 pars interarticularis. External stabilization can be effective but may prolong healing and increase morbidity. Many traditional surgical techniques can achieve internal stabilization at the expense of normal cervical motion. We describe direct surgical C2 pedicle screw fixation as an option for managing acute complex C2 vertebral body fracture.

Case Description: Three patients were treated with direct pedicle screw fixation of acute traumatic complex C2 vertebral body fractures. All fractures were coronally oriented Benzel type 1. None of the patients sustained neurological injury. Stereotactic navigation with intraoperative computed tomography scanning was used for each procedure. Surgery provided immediate internal orthosis and stability, as judged by intraoperative dynamic fluoroscopy. Rigid cervical collar bracing was used for 1 month after surgery when the patients were out of bed. Initial radiographs showed acceptable screw placement and fracture alignment. Dynamic radiographs at 3 months showed structural stability at the fracture site and adjacent levels, and complete bony union was confirmed with late computed tomography scanning (>1 year) in each case. Each patient reported resolution of trauma-related and postsurgical pain at 30-day follow-up. Postoperative Neck Disability Index questionnaires for each patient suggested no significant disability at 1 year.

Conclusions: Direct pedicle screw fixation of acute complex C2 vertebral body fracture appeared to be safe and effective in our 3 patients. It may provide a more-efficient and less-morbid treatment than halo brace or cervical collar immobilization in some patients.
