Objective To compare the clinical effect of the two operating methods: screws through fractured pedical arch operating method versus traditional operating method in the treatment of thoracolumbar burst fractures, to confirm the clinical advantages of screws through fractured pedical arch operating method in the treatment of thoracolumbar fractures. Methods A total of 62 cases suffered from thoracolumbar burst fractures were divided into two groups:screws through fractured pedical arch operating method group (n=27) and traditional operating method group (n=35). Each group was undergone the corresponding operation. The clinical results were evaluated between two groups. Results Patients in the screws through fractured pedical arch group by contrast to traditional group, margin height, Cobb's angle, internal fixation failure rates and area of vertebral canal were different, there was significant differences (P<0.01). Conclusion Screws through fractured pedical arch operating method had many advantages, which had a promising clinical applica-tion in the treatment of thoracolumbar burst fractures.
