PDFAbstract
Objective To analyze the imaging effect and classificatory diagnostic value of 16-MSCT for elderly complex fractures of bone and joint. Methods 70 patients with complex fractures of bone and joint who were treated in the hospital during May 2013 to January 2015 were taken as the research objects. All of them received digital radiography (DR) and 16-MSCT scan. After MSCT scan, multiplanar reconstruction (MPR), three-dimensional surface reconstruction (SSD) and volume reconstruction (VR) were performed. The different image fracture line findings and fracture classificatory diagnosis were compared. Results There were 215 fracture lines in 70 cases of patients. The detection rate of DR was 77.2% which was significantly lower than 97.7%, 100% and 90.7% of MSCT axial images, MPR and VR (P<0.01). For fracture classification, there were 16 cases misdiagnosed (including missed diagnosis), including 6 cases of tibial plateau fractures, 3 cases of spinal fractures, 5 cases of acetabular fractures and 2 cases of ankle fractures. Conclusion Compared with DR, 16-MSCT and its multiple reconstruction techniques have obvious advantages in imaging effect and classificatory diagnosis of elderly complex fractures of bone and joint.
