Abstract:

BACKGROUND: Two-dimensional imaging of complex intra-articular fracture can not accurately reflect the injury characteristics, but three-dimensional imaging can observe displacement fracture from three-dimensional space clearly and accurately, and thereby it can effectively guide surgery implementation of the surgeon.
OBJECTIVE: To investigate the clinical efficacy of support plate for the treatment of tibial plateau fractures assisted with intra-operative three-dimensional imaging.
METHODS: From April 2009 to May 2010, 23 patients with tibial plateau fracture underwent open reduction and support plate fixation with intra-operative three-dimensional C-arm X-ray machine scanning to monitor fracture reduction and plate screw position as well as wound healing and complications. Rasmussen scale was used for evaluation of knee joint function.
RESULTS AND CONCLUSION: There were 17 cases in anatomic reduction one-timely, 6 cases in anatomic reduction secondly. There were 11 cases in satisfactory screw position, 12 cases in screw position adjusted. A mean follow-up of 6.2 months was performed in 18 cases. The knee function recovery according to Rasmussen scores: excellent in 9 cases, good in 8 cases, moderate in 1 case. The excellent rate was 94.4%. The results indicated that intra-operative three-dimensional imaging can monitor fracture reduction and internal fixation conditions real-timely and finely from coronal plane, sagittal plane, cross section, and three-dimensional reconstruction, and effectively improve the anatomic reduction and internal fixation location accuracy, and provides a good foundation condition for the knee function recovery.
