Abstract：Objective To compare the effect of anterior internal fixation and posterior pedicle screw fixa-tion in the treatment of lumbar burst fractures.Methods Thirty-three patients( the anterior group) with burst frac-ture of lumbar spine treated by anterior internal fixation system in our hospital from Feb.2012 to Dec.2013 were se-lected.Fifty-four patients ( the posterior group) treated by posterior pedicle screw rod system fixation were also ret-rospectively analyzed.The differences in operation time, intraoperative blood loss,loss of Cobb' s angle,Japanese Orthopaedic Association ( JOA) Scores,anterior height ratio of the vertebral body and score by American Spinal In-jury Association (ASIA) between the two groups were compared.Results The operation time of (178.8 ±55.2) min and the intraoperative blood loss of ( 750.9 ± 85.2 ) mL in the anterior group were both significantly higher than those of the posterior group[(149.3 ±38.6)min,(414.3 ±67.8)mL] and the difference was statistically sig-nificant(P<0.05).One year after surgery,Cobb's angle in the posterior group was (9.6 ±2.4)°and the loss of Cobb's angle was (6.1 ±1.9)°,significantly higher than those [(4.5 ±1.9) °,(0.8 ±0.3)°,P<0.05] in the anterior group.JOA scores before operation in the two groups had no statistical significance(P>0.05).After 1 year of operation,the JOA scores of the two groups were significantly improved and the difference was statistically significant(P<0.05).After 1 year of operation,the height ratio of anterior vertebral body height was significantly improved in the two groups(P<0.05).Difference in postoperative ASIA scores between the two groups had no sta-tistical significance( P>0.05) .Conclusion The results of the two methods in the treatment of lumbar burst frac-ture are both satisfactory.The disadvantage of the posterior group is the large loss of Cobb angle correction and the disadvantage of the anterior group is the surgical trauma.Individualized consideration should be given to the factors such as patients' surgical tolerance.
