Wong YS, Lai KKL, Zheng YP, et al. - Through a prospective study that included 952 idiopathic scolioses (IS, complex three-dimensional spinal deformity in the coronal and sagittal planes with vertebral rotation in the transverse plane) patient, researchers assessed the reliability and efficacy of ultrasound for measuring coronal Cobb angle as predicted from automatic spinous process angle (SPA) measurement in IS patients in regards to various curve levels, curve severities, body mass indices, ages, genders and heights. For upper spinal curves (USCs) and lower spinal curves (LSCs), there was a good relationship between radiologic Cobb angles measured manually on EOS (E_Cobb) whole-spine radiographs and automatic ultrasound SPA measurement among 1,432 curves that were identified via ultrasound. Taller stature was related to a stronger association. About 66.6% USCs and 62.4% LSCs had absolute variations between E_Cobb and prognosticated Cobb angle measured from SPA ≤ 5° for E_Cobb < 30°. For measuring coronal curves, ultrasound could be a viable option in lieu of radiography with apices at T7 or lower and Cobb angle < 30°
