40 patients (33 females, 7 males; age 11 to 22 yr.) operated for structural double-torsion scoliosis were followed for a minimum 2 years to compare the corrective effect of lumbar pedicle screws to lamina hooks. The lumbar curves anchored bilaterally with the screws were rotated directly in 23 patients (S group), while the curves were corrected with a 90° rod rotation maneuver using the hooks in 17 patients (H group). The S group represented significantly better coronal plane deformity correction and trended toward better transverse plane correction than the H group. Although sagittal plane regional curves were sometimes slightly, even significantly decreased, the global sagittal plane L1 and lower instrumented vertebra alignment was sometimes significantly improved in the S group. Lumbar pedicle screw anchors offered definite advantages to lamina hooks in the correction of double structural scoliosis.
