Abstract:

BACKGROUND: The technology of three-dimensional (3-D) construction of spiral CT can offer intuitionistic 3-D images. These images can be rotated randomly to allow the displacement of pelvis fracture observed from any visual angles thus clear and direct impression of fracture can be acquired by doctor.
OBJECTIVE: To observe the clinical effectiveness of 3-D reconstruction images of spiral CT in the pelvic fractures.
METHODS: From November 2007 to March 2009, 42 patients with pelvic fractures from Department of Orthopedics, Affiliated Hospital of Zunyi Medical College were selected, including 30 males and 12 females. They underwent X-ray and spiral CT scanning respectively. 3-D reconstruction was performed with surface shaded display and multi-planar reconstruction with 3-D imaging software simultaneously. These images which displayed best results of fracture were selected to store and photographed. The observation effects were compared with two scanning methods.
RESULTS AND CONCLUSION: All patients had shown fractures with spiral CT 3-D imaging radiography. The bone fragments were shown more accurately with 3-D reconstruction images. The display effect of 3-D images was better than X-ray radiography (P < 0.05). The 3-D spiral CT imaging has a very important value in the diagnosis of pelvic fractures. It can show the fracture situation of pelvis more accurately and provide evidence for the choice of treatment.
