Computer-assisted Cobb measurement of scoliosis

Computer-assisted algorithms improve reliability of King classification and Cobb angle measurement of scoliosis.

STUDY DESIGN Interobserver and intraobserver reliability study of improved method to evaluate radiographs of patients with scoliosis. OBJECTIVE To determine the reliability of a computer-assisted measurement protocol for evaluating Cobb angle and King et al classification. SUMMARY OF BACKGROUND DATA Evaluation of scoliosis radiographs is inherently unreliable because of technical and human ...

Cobb Angle Measurement of Scoliosis Using Computer Measurement of Digitally Acquired Radiographs-Intraobserver and Interobserver Variability

STUDY DESIGN We evaluated computer assisted digital measurement of radiographic parameters in patients with idiopathic scoliosis. PURPOSE To assess the reliability of digital measurements. OVERVIEW OF LITERATURE Various authors analyzed scoliotic deformities by conventional radiographs, but very few studies have addressed the reliability of digital radiographic measurement using computer so...

Cobb Angle Measurement of Scoliosis with Reduced Variability

Cobb angle, which is a measure of spinal curvature, is the standard method for quantifying the magnitude of Scoliosis, related to spinal deformity in orthopedics. Determining the Cobb angle through manual process is subject to human errors. In this work, we propose a methodology to measure the magnitude of Cobb angle, which appreciably reduces the variability related to its measurement, compare...

Reliability and reproducibility analysis of the Cobb angle assessing by Computer-assisted and manual measurement tools

Computer-assisted Cobb angle measurement from posteroanterior radiographs by a curve fitting method

Incorrect determination of the top or end vertebrae of a scoliotic curve causes measurement errors when using the Cobb method. Such problems are due to subjectivity. This study was performed to minimize subjectivity by using a curve fitting method. A digitally scanned posteroanterior radiographic image was used for each patient. User-defined midpoints of the curvature, which indicate the midpoi...
