Scoliosis does not necessarily mean that whichever shoulder is higher is which side is convex. Scoliosis, also known as scoliosis, is a three-dimensional deformity of the spine that includes sequential abnormalities in the coronal, sagittal, and axial positions. When only one type of curvature of the spine is present, the change in shoulder height can indicate the direction of scoliosis; if the curvature of the spine is more complex, the direction of scoliosis cannot be deduced from the change in shoulder height alone. If the spine curves to the right, the right shoulder will appear slightly higher, and if the spine curves to the left, the left shoulder will be slightly higher. If the thoracic and lumbar spine are also scoliotic, they may show 2 or even 3 curves. In this case, there is no particular pattern as to which shoulder is higher in scoliosis. It may happen that the left shoulder is high and the right shoulder is low, or the right shoulder is high and the left shoulder is low, or the 2 curves are at about the same angle, and the shoulders may appear to be in a state of equilibrium. As a common spinal deformity in clinical practice, each scoliosis patient is different and it is not possible to determine the direction of scoliosis by the height of the shoulders. It is recommended that patients visit a hospital and have their scoliosis analyzed after a careful examination by a medical professional.
