The diagnosis of scoliosis must be made after other causes of scoliosis have been ruled out. The diagnosis of scoliosis should be based on symptoms, physical examination, and imaging. Here are some simple methods to teach you: Symmetry of the body check: Check 1: the upper half of the body upright, the elbow flexion 90 degrees, and then from the back of the body to see whether the height of the elbow joint is the same, if not, the spine has a deviation. Of course, you can also look at both shoulders to determine whether the level. This method checks the degree of scoliosis of the spine in the front and back. Examination 2: Let the examinee’s arms hang down naturally, with the head slightly raised, the lower limbs standing straight with the shoulders shoulder-width apart, and the torso at a 90-degree angle to the body. This method checks the rotation of the spine, as shown in the figure. The larger the R-value, i.e., the greater the difference in height between the two sides, the more serious the spinal vertebral rotation is proved to be. Examination 3: If the above examinations 1 and 2 can detect a problem, then it is necessary to take a standing orthopedic X-ray of the entire spine at a nearby hospital. This check method is a simple tip to teach you how to measure the angle of scoliosis; this is the measurement of “S” type scoliosis, firstly, find a vertebra with the biggest tilt at the top of the curvature, then find a vertebra with the biggest tilt below the curvature, and then make a perpendicular line along the upper edge of the upper vertebra and a perpendicular line along the lower edge of the lower vertebra, with the angle between the two lines being the same as the angle of the lower edge. The acute angle between the two lines is commonly referred to as the angle of scoliosis.
