Crestal scoliosis is a deformity in which one or several segments of the crest deviate from the midline of the body in the coronal plane and bend to the side, forming a crestal deformity with a curvature, which is usually accompanied by rotation of the crest and an increase or decrease in the posterior or anterior process in the sagittal plane, as well as inequality in the height of ribs on the left and right sides, rotational tilting deformity of the pelvis, and anomalies of paravertebral ligaments and muscles, which is a symptom or an X-ray sign and can be caused by many diseases. Causes. Crestal scoliosis usually occurs in the cervical, thoracic, or crestal vertebrae between the thorax and the lumbar region, or it can occur in the low back alone. The scoliosis appears on one side of the crus, in a “C” shape, or bilaterally, in an “S” shape. The incidence rate of scoliosis among adolescents in China is about 1-3%, which is quite high, and 0.25-0.27% of them need to be treated, while the number of those who really get treatment is very small. At present, the examination of the crural column is not included in the routine physical examination of students, so students and parents should pay extra attention to the possibility of crural deformity. Many people don’t even know about scoliosis, or even if they do know about it, they don’t know that it can be treated. If you find that your child has unequal shoulders, a tilted pelvis, or an abnormal bulge in the back of the chest and waist (hunchback), you should promptly go to a regular hospital specialist for an examination, get a clear diagnosis as early as possible, and get the correct and standardized treatment as early as possible, and don’t listen to ineffective or even erroneous propaganda such as hanging the bar by a charlatan, massaging the correct crest, or wearing jewelry, so as to avoid delaying the condition. It will reduce the volume of the thoracic, abdominal and pelvic cavities, and will also reduce the height. Four steps to determine whether the child’s scoliosis to determine whether the child’s scoliosis, parents should always do some simple checks on the child’s crest. Step 1: Look at the child’s shoulders to see if they are equal in height Step 2: Feel the child’s shoulder blades on the back to see if the two shoulder blades are equal in height at the lowest end, and if there is any side of the shoulder blades that bulges backward. Step 3: See if the pelvic bones on both sides of the child are equal in height. Step 4: Let the child bend over, and the parents use the middle and index fingers to draw down the crural protuberance to see if a normal straight line can be drawn; touch and compare the child’s waist and back bilaterally to see if there is a bulge. If the condition is serious, please consult a doctor promptly.
