Abstract
In Malmo, Sweden, 17,181 school children born from 1961-1965 were screened for scoliosis once a year between the ages of 7 and 16 yr, during 1971-1980. Children with clinical signs of scoliosis including a positive forward bending test were admitted to the Department of Orthopedic Surgery for reinvestigation and AP [anterior posterior] roentgenograms. There were 474 children with a scoliosis measuring 5.degree. or more (prevalence 2.8%). Among the girls this prevalence was 4.3% (n = 367) and among the boys 1.2% (n = 107). This combined screening test revealed in girls a higher percentage of scoliosis measuring 10-14.degree. than 5-9.degree., 1.3 and 1.1%, respectively. In boys, however, the number of curves measuring 5-9.degree. was almost equal to the number exceeding 9.degree.. The rotational component of the scoliosis seems to be less pronounced in girls and curves less than 10.degree. can easily be missed in them. Therefore, 10.degree. is recommended as the lower limit when using this screening technique. With 10.degree. as the lower limit, the scoliosis prevalence was 3.2% in girls and 0.5% in boys. Of the girls (96, 1.1%) that had a scoliosis exceeding 19.degree., 46 showed a progression of the scoliosis, which indicated brace treatment in 42 cases and surgical treatment in 4 cases. Among the boys 12 had curves measuring more than 19.degree. (0.14%). Four boys with curves exceeding 24.degree. were treated with a brace. The risk of progression was higher in girls as compared with boys; 0.5% of the girls and 0.05% of the boys were treated. Another 0.2% of the girls should also have been treated but, for various reasons, treatment was not carried out.
