Using just the angle of maximum kyphosis to diagnose hyperkyphosis is not enough. That single measure captures only the steepest point of the curve on a lateral radiograph, and it can be influenced by how the person is positioned, the projection of the image, or where the curve happens to peak. Hyperkyphosis, however, is about the overall amount of thoracic curvature and how it affects sagittal balance and function. Relying on one angle misses important parts of the picture, such as the total kyphotic span (the full Cobb angle from the upper to the lower end of the thoracic curve), the distribution of curvature across the spine, and whether the sagittal balance is preserved or displaced (for example, anterior translation of the head or trunk relative to the pelvis).

In practice, diagnosis involves comparing measured angles to age- and population-related norms, evaluating the full thoracic kyphosis, and considering clinical factors like symptoms, posture, and any vertebral changes (fractures, wedging, degenerative changes). So, while the angle of maximum kyphosis can contribute to the assessment, it should not be used in isolation to diagnose hyperkyphosis.
