When diagnosing scoliosis, healthcare professionals rely on a measurement known as the Cobb angle. This standard measurement assesses the degree of spinal curvature by comparing the tilt of one vertebra to another. Cobb angles are expressed in degrees and play a crucial role in classifying the severity of scoliosis.

Classifying Scoliosis with the Cobb Angle

Accurate measurement of the Cobb angle is essential for proper classification and treatment planning. The reliability of the Cobb angle measurement can be influenced by the positioning of the patient during the X-ray.

Consistency in how X-rays are taken is vital for monitoring scoliosis over time. Reliable measurements help determine whether the curvature is worsening, improving, or remaining stable, guiding treatment decisions effectively. Variations in X-ray techniques can introduce a measurement error margin of about five degrees. For instance, a Cobb angle measured at 45° by one doctor might be recorded as 50° by another due to these inconsistencies.

To minimize errors and ensure accurate Cobb angle measurements the following should be done:

Accurate Cobb angle measurements are crucial for correctly classifying the severity of scoliosis and devising an effective treatment plan.
