Value of 64-row spiral CT three-dimensional reconstruction in the repair of tibial plateau fractures / 中国组织工程研究

ABSTRACT

BACKGROUND:Tibial plateau fracture wil inhibit the normal function of the knee joint, and severely damage lower extremity function. Early diagnostic measures play a key role in prognosis. Previous studies mainly focused on multislice spiral CT three-dimensional reconstruction for diagnosis of tibial plateau fractures, but it is rare to compare diagnostic results and X-ray inspection methods. OBJECTIVE:To analyze the application effect of 64-row spiral CT three-dimensional reconstruction in the repair, diagnosis and treatment of tibial plateau fractures, and compare with diagnostic outcomes of traditional X-ray. METHODS:A total of 30 patients with tibial plateau fractures were selected from Ninth People’s Hospital of Wuxi City from October 2012 to October 2013. Patients were subjected to 64-row spiral CT scanning, three-dimensional reconstruction and X-ray plain film inspection. The inspection results were analyzed and compared. CT scanning used GE64 row spiral CT. Scanning range was the proximal tibia. Spacing of reconstruction was 1 mm. After completing the scan, data were uploaded to a working platform, and image reconstruction was completed. RESULTS AND CONCLUSION:Through 64-row spiral CT three-dimensional reconstruction, the degree of tibial plateau fractures, colapse, broken bones and displacement were clearly shown. According to the HOHI classification method: eight cases were type I, seven cases were type II, four cases were type III, five cases were type IV, three cases were type V, and three cases were type VI. The diagnosis rate was 100%. X-ray results showed that 25 cases were diagnosed, 3 cases were suspected diagnosis, 2 cases could not be confirmed. The diagnosis rate was 83%. Significant differences in the diagnosis rate were detectable between the two methods (P < 0.05). After surgical treatment, good clinical effects were found in patients. The excelent and good rate was 93%. These data suggested that 64-row spiral CT three- dimensional reconstruction has important application value in the diagnosis and treatment of tibial plateau fractures, can clearly show the characteristics of the anatomical morphology of fracture of tibial plateau, and provide important evidence for elevating repair effect.
