Surgical Management of Old L5 Traumatic Fractures with Kyphotic Deformity: Outcomes from a Retrospective Case Series Utilizing Anterior Vertebrectomy and O-Arm Navigation
To evaluate the efficacy and safety of anterior vertebrectomy and reconstruction using O-arm navigation for old L5 traumatic fractures with kyphotic deformity.
Key Findings:
Mean operation duration was 182.5 minutes with an average blood loss of 570.5 mL.
Significant improvement in VAS scores and ODI at 3 months and final follow-up (P<0.05).
VAMHR improved from 35.9% preoperatively to 92.1% at final follow-up (P<0.001).
LCA decreased from 37.8° preoperatively to 14.4° at final follow-up.
ASIA grades improved significantly, with 74.4% of patients remaining unchanged and 25.6% improving by one grade.
34 patients achieved Bridwell grade I bone fusion with minimal complications.
Interpretation:
The study demonstrates that anterior vertebrectomy and reconstruction using O-arm navigation is effective for restoring spinal stability and correcting deformity in patients with old L5 fractures.
Limitations:
Retrospective design may introduce bias.
Medium-term follow-up may not capture long-term outcomes.
Conclusion:
This surgical approach offers significant pain relief, functional recovery, and sustained spinal alignment correction with low complication rates.
