The waist slanting to one side mostly refers to scoliosis, and the correction methods are different according to the severity of scoliosis deformity. If the scoliosis is mild, observation is the main focus, and if the scoliosis is more severe, braces can be worn, surgical treatment and so on. If the scoliosis is mild and the curvature is less than 20°, usually no special treatment is needed, and you can choose the appropriate medical gymnastics according to the type of scoliosis, such as corrective gymnastics, postural training and so on. If the scoliosis is severe and the curvature is greater than 20°, corrective braces, such as Boston braces, can be worn; if the scoliosis is more than 50°, surgical treatment is usually taken to correct the deformity. Scoliosis is a common spinal deformity, mainly manifested by the spinal segments deviating from the midline, bending to the side, and cone rotation, which is mostly detected during X-ray examination. When scoliosis is detected, it is recommended to consult a doctor in time and choose the appropriate treatment under the doctor’s guidance.
