Comparing the Treatment of Congenital Spine Deformity Using Freehand Techniques In Vivo and 3D-Printed Templates In Vitro (Prospective-Retrospective Single-Center Analytical Single-Cohort Study).

Introduction: Hemivertebrae excision with local posterior instrumentation is the most common technique for treatment of patients with congenital spine deformity-it is performed at a very young age. We conducted a comparative analysis for accuracy of pedicle screw positioning in infants with congenital scoliosis of the thoracolumbar area inserted using freehand technique in vivo and 3D-printed guiding templates in vitro.

Methods: The study analyzes the results of 10 surgically treated patients with congenital deformity of the thoracolumbar spine due to vertebrae failure of formation.

Diagnosis and treatment of diastematomyelia in children: a perspective cohort study.

Study Design: Cohort study.
