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 < 2.2e] correlation between the degree of scoliosis measured with the proposed ultrasound system and the 30 cm × 90 cm X-rays in standing position. There was an intra-observer reliability of 97% [r-squared = 0.97; CI 95% (0.95-0.98) p < 2.2e] and an inter-observer reliability of 95% [r-squared = 0.95; CI 95% (0.90-0.97) p < 2.2e].
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.

青少年特发性脊柱侧弯随访期间需要进行系列X线检查。对于进展风险高的病例，每6个月或3个月进行一次。由于超声技术的进步，已验证了无需电离辐射的畸形测量系统，尽管脊柱外科医生因需要特殊软件而未常规使用。
我们研究的目的是评估基于横突定位的超声测量系统的可重复性和相关性。
前瞻性、单中心、随机、三盲。
两名接受过超声培训的独立研究人员检查了31名儿童的脊柱畸形。将测量结果与三位脊柱侧弯专家外科医生用X线进行的测量结果进行比较。由一名独立研究人员进行统计分析。使用参数方法。
我们发现，使用所提出的超声系统测量的脊柱侧弯程度与站立位30cm×90cm的X线测量结果之间的相关性为95%[（0.91-0.97）p<2.2e]。观察者内可靠性为97%[决定系数=0.97；95%置信区间（0.95-0.98）p<2.2e]，观察者间可靠性为95%[决定系数=0.95；95%置信区间（0.90-0.97）p<2.2e]。
以横突为参考，使用超声可以近似测量Cobb角。这是一种非常快速、简单的评估年轻人主要脊柱畸形测量的系统，尽管它无法估计相关的轴向或矢状面旋转。这些幻灯片可在电子补充材料中获取。
