Abstract
Pelvic radiographs of 25 children aged 6 months to 2 years had the acetabular index measured 3 times by each of five pediatric orthopaedists. Interobserver measurements were found to vary +/-3.0 degrees, whereas the intraobserver variation was +/-3.6 degrees. This error reflects only measurement error and does not consider error introduced with different positioning of the pelvis.
