Sung, Choi, Lee, Kim, Cho, and Shim: The Measurement of Femoral Ant eversion Using Ultrasound

Abstract

The measurement of the angle of anteversion of femoral neck by ultrasound is a method of non-invasive, accurate and easily applicable. We, Dept. of Orthopaedic Surgedic Surgery, Soon Chun Hyang Hospital, have been adopted this method since May 1984. The result in this paper was limited to 50 normal adult subjects above 20 years of age. We assessed the accuracy of measurement of the femoral anteversion and ascertained the normal range of the angle of anteversion in adult population by using ultrasound scanning. The results were as follows: 1. Of the 50 cases 25 persons were male and 25, female and they ranged from 21 to 59 years in age, average 33 years in age. 2. In general, the range of the angle of anteversion was from 4 to 31 and an average of that, 17.7±6.45° (M±SD) and 17.2±6.27° (M±SD) in right and left -espectively. 3. The angle of femoral anteversion in male was 16.6±7.26° and 16.0±6.89° in right and left. The range was from 4° to 30° and from 6° to 29° in right and left. 4. The angle of femorai anteversion in female was 18.8±4.90° and 18.4±5.16° in right and left. The range was from 12° to 31° and 9° to 27° in right and left. 5. The angle of femoral anteversion in female was greater than that in male, such as in right side, was greater and in left, 2.4° was greater also but no significance was noted statistically. 6. The angle of femoral anteversion in right side was greater than that ir, left side, such as in male, 0.6° was greater and in female, 0.4° was greater also but no significance was noted statistically. 7. The differen ce between right and left was 2.06±1.35° totally, in male 2.28±1.51° and in female, 1.84±1.12°. The difference in male was greater than that in female but no significance was noted statistically.
