The normal sagittal Cobb angle refers to the average values of the angle measurements in the sagittal plane of the spine. This angle is used to assess the curvature of the spine, specifically in the sagittal (front-to-back) plane. It is an important measurement in diagnosing and monitoring conditions such as scoliosis and kyphosis.
In this particular study, the researchers measured the normal sagittal Cobb angle in different segments of the spine. The average values were reported for each segment, including T12, L1, L2, and L3. It is important to note that the values reported are averages and may vary slightly among individuals.
The normal sagittal Cobb angle in the T12 segment was found to be -5.196 ± 3.318°. This means that, on average, the spine in this segment has a slight backward curve or kyphosis. However, the angle is within the normal range, indicating a normal curvature.
Moving down the spine, the average sagittal Cobb angle in the L1 segment was measured to be 2.279 ± 3.324°. This suggests a slight forward curve or lordosis in this segment, which is also within the normal range.
The L2 segment showed an average sagittal Cobb angle of 7.222 ± 2.798°. This indicates a more pronounced lordosis or forward curve compared to the previous segments. Again, the angle falls within the normal range.
In the L3 segment, the average sagittal Cobb angle was reported to be 12.417 ± 11.962°. This segment shows the greatest degree of lordosis among the measured segments, suggesting a more significant forward curve in this region.
It is important to remember that these average values represent a general range and may vary among individuals due to factors such as age, gender, and overall spinal health. Additionally, it is crucial to consider the specific context of each patient’s condition when interpreting sagittal Cobb angle measurements.
The normal sagittal Cobb angle varies along different segments of the spine. The average values reported in this study provide insights into the typical curvature found in the T12, L1, L2, and L3 segments. These measurements help clinicians assess and monitor spinal alignment and curvature abnormalities.
