Clinical Application of Spiral CT 3D Reconstruction to Acetabular Fracture

Objective To evaluate clinical value of spiral CT three dimension reconstruction (3DCT) in diagnosis of acetabular fracture. Methods Thirty three cases of acetabular were underwent thin slice volume scan and then 3D reconstruction in ways of surface shaded display (SSD) and volume rendering (VR) by single slice (23 cases) or multi slice (10 cases)spiral CT;results of 2DCT and 3DCT were analyzed and compared. Results 3DCT could evaluate stereoscopically and accurately conformation,type,fracture displacement,hip dislocation and other space information,but was worse than 2DCT in detecting small and false fracture and false hole existed in 3DCT. Conclusion 3DCT takes advantages of displaying space relation of acetabular and has obvious clinical value.
