Operation Treatment Of Lumbar Disc Herniation Combined With Lumbar Instability

Objective: Comparative study of minimally invasive by the intervertebral foramenintervertebral fusion (MIS-TLIF) and traditional open posterior intervertebral fusion (PLIF)combined treatment of lumbar intervertebral disc protrusion clinical curative effect oflumbar instability.Methods:Were retrospectively analyzed from March2012to October2012inshandong province hospital of44cases with complete data merging of lumbarintervertebral disc protrusion patients with lumbar spinal instability, raw of minimallyinvasive intervertebral foramen intervertebral fusion (MIS-TLIF) patients21cases, andtraditional open posterior intervertebral fusion (PLIF) in patients with23cases, accordingto the different surgical methods are divided into two groups A and B. Comparison of twogroups of operation time, incision length, intraoperative blood loss, postoperative flow,preoperative and postoperative1week,3month, the last follow-up for visual analog pain(VAS) score and JOA scores. According to JOA (Japanese orthopedic association) scoresassessment of lumbar function before and after treatment, calculation period, follow-upbone graft fusion. Application of statistical software for statistical analysis the results.Results: All patients were followed up, follow-up time was10~18months, an averageof14.6months, has not been found during the follow-up period pedicle screw looseningand fracture, shift of the Cage or sink. Minimally invasive TLIF group of intraoperativeblood loss, length of incision, postoperative led traffic were better than the open group (P <0.01); Two groups of patients with postoperative JOA score, VAS score, both preoperativeobviously improved, the difference is statistically significant (P<0.01); Minimally invasiveTLIF group after1week,1month back pain VAS score and JOA score is better than theopen group (P<0.05); Postoperative follow-up of12months, two groups of patients withintervertebral fusion rate, the difference between the two groups had no statisticalsignificance (P>0.05);Conclusion: Merger of lumbar disc prolapse lumbar instability treated with surgery, no matter with minimally invasive intervertebral foramen intervertebral fusion ortraditional open posterior intervertebral fusion (PLIF) can obtain good clinical curativeeffect; Minimally invasive TILF group than traditional PLIF less intraoperative bleeding,less postoperative led traffic; Minimally invasive TLIF in the short-term curative effect issuperior to traditional PLIF group; Therefore, minimally invasive TILF technologycombined treatment of lumbar intervertebral disc protrusion of lumbar instability, smalltrauma, quick recovery, the characteristics of the short-term curative effect, is a kind ofsafe and reliable technique worthy of popularizing. Less number of cases of this research,follow-up time is not long enough, the need to further expand the sample and long-termfollow-up study.
