Abstract:
The acetabular angles were measured in 2 groups of selected 100 infants and children each, of whom one group aged 14 months and younger and the other group aged 15 months of 5 yrs. and who were proved to be normal by all the physical examination and whose acetabular angles were below 40 according to Coleman's diagnostic criteria. The measurements were broken down into right and left, and male and female because of the known difference in the incidence of CDH in 2 members of each of these paired categories and analysed statistically. The following statistic significances resulted: l. All the measured normal acetabular angles vary between 10 and 31 degrees. 2. The acetabular angles decrease after weight bearing by the statistical significant difference between 0-14 mo. group and 15 mo-5yr. group. The angles are 22,61±3,47 (M±S,D) and 18.68±3.64 (M±S.D) respectively. 3. The acetabular angles of female of 15mo.-5yr. group are higher than male by the statistical significant difference. The angles are 17.77±3.54 (M±S.D) and 20.18±3.29 (M±S.D) respectively. 4. Statistical significant differences were absent between right and left.
