548 Korean high school girls and 565 high school boys were preliminarily screened for spinal deformities including scoliosis, thoracic kyphosis and lumbar lordosis by forward bending test and physical examinations and three dimensional skeletal analysis system. The subjects were confirmed for scoliosis by whole spine radiography, which was seen a Cobb's angle of more than 10 degrees. The difference of scoliosis prevalence rate, degree of curvature, pattern and direction of curvature between female and male high school students were evaluated. The overall scoliosis prevalence rate screened by three dimensional skeletal analysis system as angle of more than 10 degrees was 17.8% in female and 8.1% in male. 12.4% of the cases in female and 9.2% in male showed thoracic kyphosis of more than 45 degrees by three dimensional skeletal analysis system.
In addition, lumbar lordosis of more than 50 degrees was seen in 0.4% of female cases and 0.5% of male cases. 44 out of 96 female students and 29 out of 46 male students who revealed estimated scoliosis angle of more than 10 degrees by three dimensional skeletal analysis system took the confirmative radiographical study, which revealed the prevalence of scoliosis as a 33 out of 548(6.0%) cases in female and 19 out of 565(3.4%) cases in male with Cobb's angle of more than 10 degrees.
