Comparative Analysis Of Anterior And Posterior Surgical Treatment Of Thoracolumbar Burst Fractures

Objective: To retrospectively analyzed the clinical effect of posterior spinaldecompression and anterior decompression in thoracolumbar burst fractures.Methods: Forty-four patients which had spinal decompression operation fromfebruary2009to february2012in our hospital were included in the study,and it divided into two groups, including the posterior group of23patients,21casesof anterior group. Observed the operation time,intraoperative and postoperative bleeding, postoperative complications; We evaluated postoperative recovery of neurological function by using the Frankel grade, and we observed the evaluation ofvertebral height, Cobb angle and spinal canal stenosis recovery through imaging studies.Results: The study compared:the posterior operative time was80±15min, the anterior group was150±30min, the difference was statistically significant (P<0.05); posterior amount of blood loss was215±25ml, the anterior group ofblood loss was535±150ml,difference statistically significant (P<0.05); posterior group of postoperative drainage was154±11ml, the anterior group was271±53ml, compare the difference was statistically significant (P<0.05). Compare the incidence of early postoperative complications and long-term residual low back painincidence between the posterior and the anterior group,we found that the posteriot were superior to the anterior group and had statistically significant (P<0.05).Posterior group were superior to the anterior group and had statistically significant (P <0.05) in the rate of vertebral height correction and the rate of Cobb angle correction.However, postoperative nerve injury in the degree of recovery was statistically significant (P>0.05) between the two groups.Conclusion: We chould found that both the posterior spinal decompression a nd anterior decompression surgery in the treatment of fresh thoracolumbar burst fracture were well promote the recovery of nerve damage,but posterior surgical procedure easier,shorter operative time,less bleeding.So the posterior decompressionand internal fixation were preferred by us in the fresh thoracolumbar burst fracture, but the long-term effects still need long-term follow-up of a large sample.
