[The value of femoral anteversion angle measured clinically and on radiographs]

The purpose of the study was to analyze the value of clinical and radiological measurements of femoral anteversion. There were 49 patients (39 girls, 10 boys) with the mean age of 9.1 years (range from 4 to 15 years) at last follow-up. Among 98 analyzed hips 59 had IIb hip dysplasia according to Graf at childhood. Clinically femoral anteversion angle was measured using the trochanteric prominence angle test. On radiographs femoral anteversion angle was measured according to Strzyzewski method. Femoral anteversion wasn't significantly increased in joints type IIb. The correlation of clinical and radiographic determination of femoral anteversion was good (r=71) and it is recommended for routine examination. Hip rotation in flexion (r=59) better correlated with radiographic anteversion than in extension (r=46) and their combination increased correlation (r=62). Clinical examination in hips flexed 90 degrees allows for better assessment of femoral anteversion than examination done in hip extension.
