The Comparison Of Clinical Efficacy Treatment Of Lumbar Spondylolisthesis Between Posterior Lumbar Interbody Fusionand Transforaminal Lumbar Interbody Fusion

Objective:A comparative analysis of posterior lumbar interbody fusion and by the transforaminal lumbar interbody fusion for the treatment of isthmic and degenerative spondylolisthesis clinical efficacy, in order to provide basis for further clinical applications.Methods:From July 2006 to July 2009 due to spondylolisthesis, in the Shandong Medical University 2nd Affiliated Hospital of Orthopedic surgery hospital patients.35 cases of spondylolisthesis patients receiving two different types of surgical treatment. According to the different treatment methods were divided into 2 groups:Posterior lumbar interbody fusion and pedicle screw system fixation (A group, a total of 19 patients),6 females and 13 males, aged 33 to 69 years; Posterior transforaminal lumbar interbody fusion and pedicle screw system fixation group (B group, a total of 16 patients),4 females and 12 males, aged 35 to 67 years. Two groups of patients for operative time, blood loss, postoperative drainage, the incidence of surgical complications and postoperative fusion rates compared; According to the preoperative, postoperative and follow-up when the JOA score, VAS pain score, Oswestry dysfunction, and Suk S fusion criteria were analyzed. Statistics SPSS13.0 major application software processing.Selective line t test, X2 test or analysis of variance for statistical analysis and processing, in order to observe and evaluate the efficacy of two kinds of fusion methods on postoperative effects.Results:35 cases of postoperative follow-up time of 3 to 12 months, an average of 10.5±1.4 months. Group B patients in the intraoperative blood loss, postoperative drainage flows were lower than group A patients, there is a significant difference (P< 0.05). B postoperative complications were significantly less than the A group, the difference was statistically significant. Through the JOA score, A, B groups, the average recovery rate was 78.6±4.6%,81.4±3.8%, between the two groups had significant differences. VAS pain score,ODI index assessment, intervertebral height and loss of a comparative analysis of fusion rates was no significant difference.Conclusion:Use of posterior foraminal interbody fusion with pedicle screw system for treatment of lumbar spondylolisthesis with conventional posterior lumbar interbody fusion-type compared to less bleeding, fewer complications and better recovery rate of low back pain. Long-term effects from the point of view, PLIF and TLIF in VAS pain score, ODI index, interbody fusion rates and high loss rates no significant difference, both of which are the effective treatment of lumbar spondylolisthesis surgical.
