Summary
Measuring the true spine growth during growing rod (GR) lengthening is limited with 2D radiographs. With 3D imaging, this study demonstrates that during GR lengthening the spine lengthens and vertebra increase in size suggesting spinal growth that matches the relative increase in rod length during the distraction period.
