Serial X-rays are needed during the follow-up of adolescent idiopathic scoliosis. They are done every 6 or 3 months in cases of high risk of progression. Thanks to the advances in ultrasound techniques, deformity measurement systems free from ionizing radiations have been validated, although spinal surgeons did not use them routinely due to the need of special software.
The aim of our work is to assess the reproducibility and correlation of an ultrasound measuring system based on the positioning of the transverse processes.
Prospective, single center, randomized, triple blinded.
Two independent researchers trained in ultrasound examined the spinal deformities of 31 children. The measurements were compared against those performed with an X-ray by three scoliosis expert surgeons. Statistics were performed by an independent researcher. Parametric methods were used.
We found a 95% [(0.91–0.97) p
An approximation of the Cobb angle measure is possible with ultrasound by using the transverse processes as reference. This is a very rapid and simple system for assessing the principal spinal deformity measure in young people, although it does not allow estimating the associated axial or sagittal rotation.
