ABSTRACT
Objective To evaluate the clinical value of 16 slice spiral CT 3D imaging in bone and joint trauma. Methods 30 patients with bone and joint trauma were collected.The patients received the 16 slice CT three-dimensional imaging and X -ray examination .The detection rate of bone and joint trauma , bone fracture , the collapse of the diagnosis were compared between the two methods .Results The detection rate of tibial fracture of 16 slice CT was 26.20％,which was higher than 3.33％of X-ray (χ2 =5.19,P=0.02).The detection rate of spinal fractures of 16 slice CT was 28.50％,which was higher than 6.67％of X-ray (χ2 =5.45,P=0.02).The detection rate of rib fracture of 16 slice CT was 30.00％,which was higher than 10.00％of X-ray (χ2 =4.81,P=0.02).The detection rate of pelvic fracture of 16 slice CT was 14.50％,which was higher than the X -ray (χ2 =4.29,P=0.04).The detection rate of tibial broken bone of 16 slice CT was 20.00％,which was higher than 3.33％ of X-ray (χ2 =4.04,P=0.04).The detection rate of pelvis broken bone of of 16 slice CT was 13.33％,which was higher than X-ray (χ2 =4.29,P=0.04).Conclusion 16 slice spiral CT three -dimensional reconstruction can accurately display the three-dimensional shape of lesions ,but also display the anatomical structure of spatial relations ,it is an ideal method for the diagnosis of fracture fragments of traumatic fracture .
