Routine Sectioning of the C2 Nerve Root and Ganglion for C1 Lateral Mass Screw Placement in Children: Surgical and Functional Outcomes, and Patient SatisfactionKeywords: spinal fusion, survey, outcome, technique, cervical spineInteractive Manuscript
Ask Questions of this Manuscript:
What is the background behind your study?
Transarticular screw fixation can successfully treat atlantoaxial and craniovertebral instability in children. Adult studies have shown that sectioning the C2 nerve root and ganglion, which facilitates placement of C1 lateral mass screws, can decrease operative time and blood loss (EBL).
What is the purpose of your study?
Functional outcomes and complications following sectioning of the C2 nerve root and ganglion have not been reported in children.
Describe your patient group.
Fifteen consecutive pediatric patients (mean age 12.6 years) underwent bilateral C2 nerve root and ganglion sectioning to facilitate C1 lateral mass screw insertion.
Describe what you did.
Clinical and radiographic assessments were performed at follow-up. Numbness in the C2 distribution and/or occipital neuralgia was assessed. Operative times, EBL, length of stay (LOS), and complications were recorded.
Describe your main findings.
Average follow-up time was 29.8 months (range 2-47 months). Mean operative time was 251.73 minutes (range 124-472 minutes), mean LOS was 8.46 days (range 5-17 days), and mean EBL was 343.6cc (range 20-1100 cc). There were no intraoperative complications, and no patient reported new onset occipital neuralgia or numbness in the C2 distribution. Fourteen of 15 patients achieved Lenke fusion grade A.
Describe the main limitation of this study.
This is a retrospective study.
Describe your main conclusion.
In our series of pediatric patients, sectioning of the C2 nerve root and ganglion enhanced surgical exposure of the C1 lateral mass and C1-1 facet joint, maximizing fusion rate and minimizing intraoperative complications.
Describe the importance of your findings and how they can be used by others.
This technique may improve operative times, EBL, and LOS in children undergoing C1 lateral mass screw insertion. Sectioning of the C2 nerve root and ganglion did not negatively affect functional outcome in these patients.
