Purpose The purpose of this study is to decrease the frequency of the perioperative complication and improve the clinical outcomes of multilevel lumbar degenerative disease by multilevel minimally invasive transforaminal lumbar interbody fusion.
Materials and Methods 317 patients(Minimally invasive transforaminal lumbar interbody fusion : 161, Conventional open surgery : 156) were followed up for more than 1 year. The age of each patient, the amount of intraoperative blood loss, the postoperative drainage, the transfusion requirement, surgery time, using of Intensive care unit, ambulation day, admission day and perioperative complications were investigated and analyzed.
Results Minimally invasive transforaminal lumbar interbody fusion was found to have a less blood loss, less using of Intensive care unit. And as the levels of union increase, disparities were increased(p<0.05).
But, surgery time of Minimally invasive transforaminal lumbar interbody fusion was longer, and as the levels of union increase, disparities were increased(p<0.05).
Conclusions Multilevel Minimally invasive transforaminal lumbar interbody fusion can be the better way, If surgery time of Multilevel Minimally invasive transforaminal lumbar interbody fusion can be reduced.
