AF钉内固定治疗胸腰椎骨折的临床效果分析

目的研究AF钉内固定治疗胸腰椎骨折的的临床效果。方法选择2011年1月～2014年1月本院收治的56例胸腰椎骨折患者,按照随机数字表法分为试验组（31例）与对照组（25例）,试验组采用AF钉内固定方法治疗,对照组采用RF钉内固定方法治疗。治疗后,比较两组患者的伤椎各参数、手术时间、手术出血量、神经恢复情况及并发症发生情况。结果术后两组患者伤椎（前缘/后缘）高度、伤椎椎管面积、矢状面位移及Cobb角均较术前显著改善（P〈0.05）;试验组伤椎（前缘/后缘）高度及Cobb角较对照组改善显著（P〈0.05）。试验组手术时间短于对照组,手术出血量显著少于对照组（P〈0.05）。两组患者神经功能恢复情况及不良反应发生情况比较,差异无统计学意义（P〉0.05）。结论采用AF钉内固定治疗胸腰椎骨折效果良好,手术时间短,出血少,值得临床推广应用。

The clinical effect of AF nail fixation in treatment of thoracolumbar frac-tures

Objective To study the clinical effect of AF nail fixation in the treatment of thoracolumbar fractures.Methods 56 cases of patients with thoracolumbar fracture treated in our hospital from January 2011 to January 2014 were selected,and were randomly divided into experimental group（31 cases） and control group（25 cases） according to the random number table method,AF nail fixation method was given to the experimental group,RF nail fixation method was taken to the control group.After treatment,patients′ vertebral various parameters,operative time,blood loss,neurological recovery and adverse events was analyzed. Results After treatment,hurt vertebral（leading/trailing edge） height,vertebral canal area,sagittal displacement and Cobb angle of two groups was improved compared with before treatment,the difference was significant（P〈0.05）;hurt vertebral（leading/trailing edge） height and Cobb angle of experimental group improved more than that of control group,the difference was significant（P〈0.05）.The operative time of experimental group was shorter than that of control group,blood loss was less than that of the control group,the difference was significant（P〈0.05）.There was no significant difference about neurological functional recovery and the incidence of adverse reactions between the two groups（P〉0.05）. Conclusion AF nail fixation for treatment of thoracolumbar fractures makes good results,shorter operative time,less bleeding,and is worthy of clinical application.
