Abstract：Objective To investigate the therapeutic effect of pedicle screw fixation via modified posterior ap-proach and conventional posterior median approach in the treatment of thoracolumbar vertebral fracture .Methods Nine-teen-eight cases of thoracolumbar vertebral fractures were selected in our hospital from Feb .2010 to Feb.2014,who were treated by pedicle screw fixation (PSF).Patients were divided into the control group(n=49 cases,using the traditional method) and the observation group(n=49 cases,using modified posterior approach).The differences of operation re-lated indexes , the height of the injured vertebral body and the correction of Cobb angle were compared between the two groups.Visual analog scale (VAS) and serum creatine kinase isoenzyme (CK-MB) were observed.Results The op-eration time,bleeding volume and drainage rate of the observation group were significantly lower than those in the con -trol group(P<0.05).In the two groups, the height of the injured vertebral body and the Cobb angle after operation were significantly better than those before operation (P<0.05),but there was no significant difference between the two groups after operation ( P>0.05 ) .The VAS score at 2 weeks and 1 month after operation in the observation group was significantly lower than that of the control group ,CK-MB at postoperative days 1 and 3 in the observation group was significantly lower than that of the control group (P<0.05).Conclusion Compared with the conven-tional posterior median approach , modified posterior vertebral approach for treating thoracolumbar vertebral fractures has advantages of short operation time ,rapid functional recovery ,less trauma,less surgical injury,and obvious pain relief,which is worth to be widely applied in clinical practice .
