13 de mar. de 2024 · The Cobb angle is the most widely used measurement to quantify the magnitude of spinal deformities, especially scoliosis, on plain radiographs. Scoliosis is a lateral spinal curvature with a Cobb angle of >10° 4. The Cobb angle technique can also assess the degree of kyphosis or lordosis in the sagittal plane 7.
The Cobb Angle is used as a standard measurement to determine and track the progression of scoliosis. Dr John Cobb invented this method in 1948.
Cobb angles of more than 50 degrees at skeletal maturity progress at about 1 to 2 degrees per year. History. The Cobb angle is named after the American orthopedic surgeon John Robert Cobb (1903–1967).
Here is a general outline of Cobb angle ranges and what they could indicate in idiopathic scoliosis found in children and adolescents: 1 to 9-degree curve. Curves that are less than 10 degrees are not considered to represent scoliosis, but rather a minor spinal asymmetry. 10- to 24-degree curve.
Ângulo de Cobb. No método de Cobb, traçam-se duas linhas em uma radiografia póstero-anterior da coluna vertebral, uma que se estende do topo da vértebra superior mais inclinada e a outra da base da vértebra inferior mais inclinada. O ângulo formado por essas linhas é o ângulo de Cobb.
19 de fev. de 2019 · A Cobb angle in the range of 10 to 20 degrees is considered as mild scoliosis. Scoliosis severity is moderate when the Cobb angle ranges from 20 to 40 degrees. A Cobb angle greater than 40 degrees denotes severe scoliosis.
For example, in the lumbar spine, the range of normality is found to vary from 26° to 58° Cobb-angle (Prospst-Proctor & Blac, 1983), or from 13° to 78° Cobb-angle (Bernhardt & Bridwell, 1989).
