抗旋转复位内固定器、AF及Dick钉治疗胸腰椎骨折的临床观察

目的 比较自行设计的抗旋转复位内固定器(ARRIF)、AF及Dick钉治疗胸腰段脊柱骨折的疗效。方法 治疗90例胸腰段脊柱骨折患者，从复位效果、手术时间、术中出血量及并发症的发生率等方面进行观察，比较ARRIF与AF、Dick钉的临床差异。结果 ARRIF的手术时间较AF、Dick钉短，术中出血量也较少，没有出现断钉、断杆及拔钉等并发症。结论 ARRIF与AF、Dick钉虽都能对不同类型的胸腰段骨折进行复位和固定，但ARRIF的使用较为方便，是一种固定较为确实的经椎弓根内固定器；其他两种内固定器以AF的使用较为方便。

Clinical observation on treatment of thoracolumbar fractures using anti-rotation reduction internal fixators, atlas fixator and Dick screw

Objective To compare the treatment effects of self-designed anti-rotation reduction internal fixators (ARRIF), atlas fixator (AF) and Dick screw in reduction and fixation of different thoracolumbar spinal fractures. Methods Reduction effect, operation time, bleeding volume during operation and complications were observed and compared after ARRIF, AF and Dick screw were used to treat 90 cases of thoracolumbar spinal fractures. Results Compared with AF and Dick screw, the operation time of ARRIF was shorter with less bleeding volume during operation as well as less complications like broken or pulled-out screw or broken rod. Conclusions All three fixation methods can attain the reduction and fixation of various kinds of thoracolumbar spinal fractures. However, ARRIF is the most valuable transpedicular internal fixator and can more conveniently reduce and fixate the different spinal fractures and AF places the second.
