A Reliable Semi-automatic Program to Measure the Vertebral Rotation Using the Center of Lamina for Adolescent Idiopathic Scoliosis

Validity Study of Vertebral Rotation Measurement Using 3-D Ultrasound in Adolescent Idiopathic Scoliosis

“…The intra-and inter-rater ICC values of this method ranged from 0.987 to 0.997 (Chen et al 2015, Vo et al 2015. In this clinical study, the results were consistent with the previous phantom study.…”

“…Prior to measurements, the level of apical vertebra was selected with reference to the MRI images. The center of laminae (COL) method was applied to measure the apical vertebral rotation (AVR) in the 3-D ultrasound images (Chen et al 2015, Vo et al 2015. The two raters identified the centers of laminae manually in the transverse plane of apical vertebral level.…”

“…Spinous processes, laminae and transverse processes can be visualized and used as landmarks to measure the lateral curvature and vertebral rotation in the coronal and transverse planes of the ultrasound images , Li et al 2012, Ungi et al 2014, Wang et al 2015. Recently, the center of laminae (COL) method has been proposed to measure the vertebral rotation in the transverse plane of 3-D ultrasound images (Chen et al 2015, Vo et al 2015. The reliability and validity of this proposed method have been demonstrated.…”

Assessment of Maximum Spinal Deformity in Scoliosis: A Literature Review

“…The ultrasound technique is characterized by radiation-free and user-friendly. It has been demonstrated to be reliable and accurate for the assessment of spinal lateral curvature [53][54][55][56][57] and AVR [58][59][60], and used for assessing the spinal flexibility [61][62][63][64] and curve progression [65] as well as the spinal orthosis casting [66] and fitting [67]. In a study of Trac et al [30], the PMC measurements obtained using the ultrasound technique were very reliable (ICC>0.92), and also strongly correlated to those obtained from the EOS system (R 2 =0.88).…”
