Abstract：Objective To explore the effect of transpedicular fixation combined with vertebral plasty in the treatment of senile thoracolumber burst fracture .Methods Sixty-five cases of senile thoracolumber burst fracture treated in our hospital from Jan.2012 to Jan.2015 were selected.There were 31 males and 34 females,aged from 55 to 76 years,with an average of (62.3 ±4.8) years.All fractures were caused by high energy shock and suffered from osteoporosis .They were treated with transpedicular fixation combined with vertebral plasty .The clinical data was analyzed . Results All operations were performed successfully .The average operation time was ( 83.6 ± 22.7)min;the average bleeding volume was (328.6 ±76.5)mL;and the average postoperative hospitalization time was (7.4 ±1.6)d.There was no serious complication during the follow-up period.The postoperative VAS scores were significantly lower than preoperatively (P<0.05);the postoperative SF-36 scores were significantly lower than preoperatively(P<0.05).The average Cobb angle after operations was (5.3 ±1.3)°,which was significantly lower than preoperatively[(23.4 ±4.7)°,P<0.05]; the Cobb angle at the end of follow-up was (6.1 ±2.4)°,which was (0.9 ±0.2)°higher than immediately after surgery .The vertebral height compression ratio after operation was (96.4 ±3.1)%,which was higher than preoperatively (57.5 ±6.9)%.The vertebral height compression ratio was (90.8 ±4.0)%at the end of follow-up and was decreased by (5.7 ±1.1)%when compared with the value at dis-charge .Conclusion The effect of transpedicular fixation combined with vertebral plasty in the treatment of senile thoracolumber burst fracture is excellent with low complication rate and can effectively restore vetebra height .It is worth clinical application .
