Abstract:

BACKGROUND: Significance of multiple helical CT posterior reconstruction technique for fracture diagnosis has been confirmed. The posterior processing software can be used for diagnosis of various injuries out of joint.
OBJECTIVE: To evaluate the value of reconstruction techniques posterior to 64-slice CT imaging in the diagnosis of joint fracture. 
METHODS: A total of 36 patients with joint fracture underwent plain X ray film and helical CT scanning. Osteoarticular injury was determined by X ray film, multi-planar reconstruction (MPR) and volumetric reconstruction (VR), and the results of different methods were analyzed.
RESULTS AND CONCLUSION: In all cases, 20 showed fracture by plain X ray obviously with the modality and direction. All cases showed modality and direction excellently by VR reconstructed images, but the details of the slightly cortical abruption were not distinct. All cases had fracture by MPR technique and the segment shift of the fracture was fairly displayed. 64-slice CT postprocessing images can clearly display osteoarticular injury, and it is of high value in clinical practice.
