1. Conclusions The development of acetabular anteversion in children is a slow process.

2. Methods 30 volunteers were chosen anteversion angle of 40 femurs with CT.

3. Objective To discuss the femoral neck anteversion(FNA) of developmental dislocation of the hip(DDH) and guide operation with visual and digitalized picture in the dimensional(3D) CT.

4. Various methods measuring canine femoral neck anteversion have been proposed in literatures.

5. Results We found the degree of acetabular anteversion less in children than in adults.

6. The relation among the angles of femoral anteversion, neck-shaft and projection of femoral neck and shaft was researched by imitating. And its clinical significance was discussed.

7. Femoral neck anteversion ( FNA ) of present model was measured by 3 D CT method.

8. Objective To compare the acetabular anteversion difference between developmental dysplasia of hip and normal controls.

9. Simulate anteversion uterus, fallopian tubes, labium, vagina and transparent abdominal wall cover in the pelvic cavity.

10. Objective:To study the change of acetabular anteversion in developmental dysplasia of hip, in order to select operation type and suppose the prognosis.

11. Most such stems hae a few degrees of anteversion built into the neck to compensate for this, and separate right and left stems are required.

12. Conclusion Acetabular anteversion in the dysplasia hips resembled the normal side. Acetabular anteversion can be changed in the operation.

13. Objective: To study the serial changes of cervicofemoral angle (CA) and femoral neck anteversion (FNA) during the close reduction treatment of developmental dislocation of hips (DDH).

14. A common error is to inadvertently insert the cup in too much anteversion.

15. Objective To compare the accuracy of measuring femoral neck anteversion angle between a new method, single X-ray film,(sentencedict .com) and the conventional CT method.

16. Reporter the pay attention, contracts ear vigorous him, cannot hear clearly under the stage student's inquiry, then stands from the seat the anteversion body.

17. There is a tendency to hold the cup inserter too vertical, which imparts excessive anteversion to the component relative to the native pelvis.

18. Each day wakes, your clear shade in my eye anteversion.

19. Objective To probe a new approach the measurement of femoral anteversion.

20. The operation to correct hip dysplasia produced an abnormality in acetabular anteversion .
