AF系统与USS系统治疗胸腰段爆裂性骨折的临床疗效比较

目的：比较AF系统与USS系统治疗胸腰段爆裂性骨折的临床疗效。方法：2008年12月～2011年7月，分别采用AF系统与USS系统治疗胸腰段爆裂性骨折32例和33例，观察两组患者术后神经功能恢复、骨折复位、内固定及植骨融合等情况，比较两者的临床疗效。结果：经平均16个月的随访，AF和USS两种系统治疗胸腰段爆裂性骨折均有可靠的复位和固定作用，术后神经功能Frankel分级情况组间比较差异无统计学意义（P〉0．05）；但AF系统术后断钉3例，且随访期间椎体高度丢失。结论：采用USS系统复位内固定治疗胸腰段爆裂性骨折，其近期疗效优于AF系统。

Efficacy Comparison between AF Internal System and USS Internal System in Thoracolumgbar Burst Fracture

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 trea- ted 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 ef- ficiency than AF internal system in thoracolumbar fracture burst.
