Study Overview
Brief Summary
The purpose of this study was to
- investigate the degree of agreement between the ultrasound-measured depth (in the transverse median and paramedian sagittal oblique plane) and the actual depth to the epidural space in pediatric patients with scoliosis.
- investigate the quality of ultrasound view for detecting ligamentum flavum and dura mater.

Inclusion Criteria
- •pediatric patients (aged 3-14 years) with scoliosis (cobb angle >10 degree) scheduled for correctional osteotomy of the lower extremity and requesting epidural analgesia for postoperative pain control
Exclusion Criteria
- •Contraindications to epidural analgesia (local infection, blood clotting disorder, anatomical abnormality, sepsis, etc.)

Outcomes
Primary Outcomes
the degree of agreement between the ultrasound-measured depth and the actual depth to the epidural space
Time Frame: Ultrasound image, which is obtained before epidural Touhy needle insertion, will be evaluated within 1 week after epidural Touhy needle insertion
