Abstract：Objective:To compare the clinical efficacy of AF internal system and USS internal system in thoracolumbar burst fracture. Methods:65 patients were randomly divided into 2 groups ,Group 1 was treated with AF internal system ,while Group 2 was treated with USS internal system. During the follow-up time the neurological function and fracture reduction fixation were observed.Results:After mean 16 months follow-up time, all cases treated with AF internal system or USS internal system got reliable reduction and fixation, and there was no significant difference in Frankel grading of the neurological function between the two groups (P＞0.05). The height of vertebral body was lost in AF internal system group during the follow-up time, and among which, 3 cases internal fixation were broken.Conclusions:USS internal system can get better clinical efficiency than AF internal system in thoracolumbar fracture burst.
