A total of 8165 schoolchildren were screened for scoliosis by two teams
of orthopaedic surgeons using the same procedures and criteria. Of 790
children who had positive physical signs, 689 were examined
roentgenographically. Using 5 and 10 degrees as cut-off points, the
prevalence of scoliosis was 6.58 and 2.4 per cent, respectively. A
follow-up study of children who had been reported to have scoliosis at the
age of eleven months showed that only half of them actually had
scoliosis.
