Abstract

INTRODUCTION: The measurement of femoral anteversion has been a subject of interest and debate in the orthopaedic literature dating back at least to the middle of 19th century. Femoral anteversion is defined as the angle formed by the bicondylar plane and a plane passing through the center of the neck and femoral head. It can be measured by radiography, CT, MRI, Ultrasonography and clinical methods. Each with advantages and disadvantages. Hence I would like to I would like to investigate a new method using radiographic parallax – “THE PARALLAX METHOD” - to measure femoral anteversion. AIM OF THE STUDY: To evaluate the validity of a new method for measuring femoral anteversion based on radiographic parallax and comparison with biplanar radiography. MATERIALS AND METHODS: Anteversion of 50 bone specimens was measured anatomically (true value) and by parallax and biplanar radiography. RESULTS: The parallax method is comparable to biplanar radiography (P=0.253, paired t-test). Also it has high interobserver (R=0.996) and intraobserver reliability (R=0.998) and reproducible to within +/- 2 degrees. CONCLUSION: The “PARALLAX METHOD” seems to be a viable alternative to the biplanar method especially in complicated and difficult situations where positioning of the patient for taking lateral radiographs of the hip may not be possible.
