Clinical Application of CT Scanning for Fracture of Acetabulum

This paper discusses the application value of CT and 3D reconstruction for acetabulum fracture by evaluating their manifestations. In this article, 25 cases of acetabulum fracture underwent both X-ray plain film examination and CT transverse scanning, 15 of them received 3D reconstruction with MPR. The CT transverse and 3D reconstruction manifestations of the 25 acetabulum fractures were analyzed and classified according to the Letournel Classification for further study of application value of 3D reconstruction. As a result, of the 25 fractures, 10 were simple fractures detected by CT including 3 anterior wall fractures, 2 anterior column fractures, 3 posterior wall fractures, 1 posterior column fracture, 1 transverse fracture,with only 8 detected by the X ray plain films; 15 were complicated fractures including 4 anterior and posterior column fractures, 3 T-shaped fractures, 4 posterior column and posterior wall fractures, 2 anterior column and posterior semi-transverse fractures, 2 transverse and posterior wall fractures. CT transverse scans revealed 18 fracture pieces dissociating in the articular cavity, while X ray plain films showed only 12. CT transverse scans could also clearly show the soft tissue injuries from the acetabulum fractures. 3D reconstruction images stood out the factures and malpositions from the different angles. In conclusion, CT scan can produce clear images for accurate classification of acetabulum fractures and 3D reconstruction can make up for the defects of transverse imaging, which provide objective basis for the selection of the therapeutic programs and for the prognosis.
