Abstract:
Objective To study the application of spiral CT three-dimensional reconstruction in diagnosing intra-articular and other bone fractures in the earthquake of Wenchuan.Methods 25 cases with joint and other bone fractures in Wenchuan earthquake underwent multi-slice spiral CT volume scanning,the images were dealed with three-dimensional reconstruction at workstation including multiplanar reconstruction (MPR) and surface shaded display(SSD) to observe the fractures.Results 36 fractures in 25 cases were found by three-dimensional reconstruction(MPR and SSD),which included knee joint bone fracture in 6,one case was avulsion fracture of the point attached to the tibia by posterior cruciate ligament and missed by X-ray;ankle fracture in 3,1 case was Pilon fracture;shoulder fracture in 5,one case with glenoid anterior labrum missed by radiography;elbow fracture in 3;spinal fractures including cervical vertebra in 2,thoracic vertebra in 4 and lumbar vertebra in 5,2 cases were burst fracture accompanied with the articular process fracture; pelvis bone fracture in 8,1 case was sacroiliac fracture accompanied with sacroiliac separation.There were open bone fractures in 4 cases,fractures with dislocation in 6 cases,soft tissue swelling in different degree around the fractures in 25 cases.Conclusion Spiral CT three-dimensional reconstruction of bone can directly and really show the fractures that will provide in-formations for the clinical diagnosis and treatment .
