Objective: To evaluate the posterior lumbar interbody fusion (PLIF) and transforaminal lumbar vertebral interbody fusion (TLIF) under the treatment of low back pain lumbar instability efficacy of the two surgical compare as the clinical application of reference. Methods: Fujian Medical University, Provincial Clinical Medical College of Orthopaedic January 2007 to February 2009 , the hospital received under lumbar instability or potential instability of the 66 cases of patients with low back pain , which application PLIF surgery in 36 cases , application TLIF surgery 30 cases . The two sets of operations performed by the same group of doctors , with an average follow - up of 27.3 months . Compared two surgical operative time , blood loss, postoperative drainage , postoperative hospital stay , intraoperative and postoperative complications , treatment improvement rate and excellent rate of postoperative interbody fusion rate , and analysis of two generate reasons for the differences . RESULTS : PLIF group operative time was 181.4 ± 32.9 minutes , blood loss was 476.4 ± 171.8 ml , postoperative drainage was 393. 9 ± 150.5 ml , postoperative hospital stay was 11.9 ± 7.4 days , intraoperative and postoperative complications and improve treatment was 66.8 ± 12.8 % , good rate of 91.7% interbody fusion rate of 100 % ; the TLIF group of operative time was 146.7 ± 28.5 minutes , blood loss 366. 7 ± 119.1 ml postoperative drainage was 405.2 ± 248.2 ml , postoperative hospital stay was 8.2 ± 3.4 days , and after surgery with no recent complications , treatment improvement rate was 68.3 ± 12.3 % , good rate of 90.0% , interbody fusion rate was 100 %. Statistical results show that : the the TLIF group in operative time , blood loss , postoperative hospital stay , intraoperative and postoperative complications less than PLIF in postoperative drainage , treatment to improve the rate and excellent rate , interbody fusion rate ( no significant differences after more than 12 months of follow-up ) . Conclusion : the PLIF and TLIF two surgical treatment of lumbar instability of low back pain treatment rate of improvement , excellent rate of interbody fusion rates are very good results ; TLIF surgery in operative time , blood loss , intraoperative after hospitalization time , intraoperative and postoperative complications compared with the PLIF group , has obvious advantages in the salient aspects of the far lateral lumbar disc recurrence and reoperation and intervertebral disc .
