# Electromagnetic navigation-guided posterior hemivertebra resection in adult congenital spinal deformity

## TL;DR

This paper presents a successful surgical technique using electromagnetic navigation to remove a spinal deformity in two adult patients.

## Contribution

The paper introduces the use of EMN-guided posterior total hemivertebra resection in adult congenital scoliosis.

## Key findings

- EMN-guided resection achieved safe and accurate correction in two adult cases.
- The technique minimized intraoperative radiation exposure.
- Precise resection was confirmed through the clinical outcomes of the cases.

## Abstract

Hemivertebra is a congenital spinal anomaly often associated with unpredictable progression of spinal deformity, for which early conservative or surgical intervention is generally recommended. While well-documented in pediatric populations, literature on the management of symptomatic adult congenital spinal deformity remains limited. We report two consecutive cases of adult congenital scoliosis caused by an L3 hemivertebra, both successfully treated with one-stage, electromagnetic navigation (EMN)-guided posterior total hemivertebra resection and instrumented spinal fusion. EMN-guided posterior total hemivertebra resection offers a safe and accurate solution for managing symptomatic adult congenital scoliosis, while also minimizing intraoperative radiation exposure. This technique highlights its clinical utility in achieving precise resection, as evidenced by the two presented cases.
