Reexamination of the Cobb and Ferguson Angles
Journal of Spinal Disorders, 1993In scoliosis, the Cobb measure of curve severity has been recommended over the Ferguson method because it had greater magnitude and appeared more sensitive to changes during progression and after treatment. This study made comparisons between the Cobb and Ferguson measures in radiographs of patients with idiopathic scoliosis to test whether the methods

3D modeling of musculoskeletal Cobb's angles
2013 6th International Conference on Biomedical Engineering and Informatics, 2013The growth of industries has led to not only the improvement in quality of life but also increased musculoskeletal diseases due to accumulation of micro-sized damages in muscles or other tissues due to simple and repetitive lifestyle. Similarly, having curvature in the vertebrae is referred to as scoliosis, which is increasingly occurring mostly in ...

Analysis of Cobb angle measurements in scoliosis
Clinical Biomechanics, 1987The measurement of the magnitude of the deformity in idiopathic scoliosis is usually performed by either the Cobb method or the Ferguson method. In this study an error analysis of the Cobb method is given. The projection error is 3° and is more or less the same in moderate and severe scoliosis.

Prediction of Scoliotic Cobb Angle With the Use of the Scoliometer
Spine, 1996A prospective study was conducted in a young homogenous adolescent population, with the use of the scoliometer.To create a mathematic formula that provides the accurate Cobb angle of idiopathic scoliosis with the use of the scoliometer only.The scoliometer is an accepted method for detection and evaluation of scoliosis during screening programs. To the

A Keypoint Transformer to Discover Spine Structure for Cobb Angle Estimation
2021 IEEE International Conference on Multimedia and Expo (ICME), 2021Due to the ambiguity and variability of vertebrae in X-ray images, accurate measurement of Cobb angles becomes challenging. Current studies are mainly focused on direct transfer learning from semantic segmentation models or keypoint estimators. We argue that such methods ignore relationships between local vertebrae shapes and the global spine structure.

Can C2-6 Cobb Angle Replace C2-7 Cobb Angle?
Spine, 2019Study Design. Retrospective study of consecutive 113 cervical kinetic magnetic resonance images (kMRIs) and 57 radiographs. Objective. To elucidate the relationship between C2-6 or C2-7 Cobb angle and cervical sagittal alignment parameters using kMRI, and evaluate the visibility of ...

MPF-net: An effective framework for automated cobb angle estimation
Medical Image Analysis, 2022In clinical practice, the Cobb angle is the gold standard for idiopathic scoliosis assessment, which can provide an important reference for clinicians to make surgical plan and give medical care to patients. Currently, the Cobb angle is measured manually on both anterior-posterior(AP) view X-rays and lateral(LAT) view X-rays.

Surface Topography, Cobb Angles, and Cosmetic Change in Scoliosis
Spine, 2001Preliminary analysis of the clinical value of surface topography in a spinal deformity clinic.The Cobb angle is the gold standard for the monitoring of scoliosis. This study was designed to determine whether surface topography would reflect Cobb angle status with sufficient reliability to permit its safe use as an alternative means of documentation in ...

The life and legacy of John Robert Cobb: the man behind the angle
Journal of Neurosurgery: Spine, 2023In 1934, Dr. John Robert Cobb moved to New York to serve as the Gibney Orthopedic Fellow at the Hospital for the Ruptured and Crippled, now known as the Hospital for Special Surgery. In this role, Cobb was faced with a unique task that would shape not only his personal career but also the fields of scoliosis and spine care: to design the first ...

An integrative framework for 3D cobb angle measurement on CT images
Computers in Biology and Medicine, 2017Measuring the Cobb angle on computed tomography (CT) images remains a challenging but requisite task for clinical diagnoses of scoliosis. Traditionally, clinical practitioners resort to manual demarcation, but this approach is inefficient and subjective.
