| Summary: | Objective: To compare the accuracy of 2D and 3D CT measurements of femoral anteversion angle, in pediatric patients with developmental hip dysplasia. Materials and methods: Twenty patients (20 hips) with unilateral non syndromic DDH were studies. CT scans were performed using a 16 slice CT scanner to measure the femoral anteversion angle (FAVA) using 2D & 3D techniques. Findings were correlated with the intra operative measurements. Results: There was a significant difference between 2D & 3D methods. Results of clinical assessment were comparable to results of 3D CT assessment which range from 30 to 50° with a mean of 37.5°. Mean percent difference between 3D and intra operative measurement of FAVA was significantly lower than the corresponding value between 2D and intraoperative measurement of FAVA. Conclusion: 3D is more accurate than 2D in measuring the degree of FAVA in DDH patients. It is easily applied and rapid and doesn't require sophisticated software.
