Internal Morphometry of Thoracic Pedicles in the Immature Spine

Abstract

The isthmus endosteal width in >50% of the pedicles studied were less than 3.0 mm. We conclude that transpedicular fixation in the thoracic spine using pedicle screw of >3.0 mm diameter is not feasible in children and adolescents of <18 years old in our population.
