Application of three-dimensional reconstruction of computed tomography in the diagnosis and treatment of tibial plateau fractures

Abstract

Objective To investigate the application of 16-slice spiral computed tomography (CT) three-dimensional reconstruction in the diagnosis and treatment of tibial plateau fractures. Methods A retrospective analysis was performed on the clinical data of 58 patients with tibial plateau fractures from January 2014 to October 2016 in Ningbo Yinzhou People's Hospital.All patients underwent locking plate internal fixation.All patients underwent radiographs of the tibial plateau before and after surgery with 16-slice spiral CT three-dimensional reconstruction, multiplanar reconstruction technology inspection.The detection rates of tibial plateau fractures and the 7-day fracture collapse surface between the two examination methods were compared, and the knee joint function before and after surgery was evaluated. Results The detection rate of tibial plateau fractures by CT three-dimensional reconstruction examination was 100.0%, which was higher than that by the X-ray examination (89.7%), the difference was statistically significant(χ2=4.39, P<0.05). The fracture collapse value of CT three-dimensional reconstruction examination after 7 days of operation was (3.42±0.86), which was significantly higher than that of X-ray examination (1.27±0.53)(t=16.21, P<0.05). The postoperative knee function score after surgery [(56.4±4.8)points] was significantly higher than that before surgery[(83.1±7.5)points] (t=22.84, P<0.05). Conclusion The detection rate of 16-slice spiral CT three-dimensional reconstruction and multi-planar reconstruction is higher than X-ray film in tibial plateau fractures, especially for invisible fractures of the tibial plateau.It is more comprehensive and intuitive, multi-faceted display of fracture types and local structural relationships, which is worthy of clinical application.
