Early Clinical Effect of Minimally Invasive Wiltse Admission Passage MIS-TLIF in Treatment of Lumbar Vertebra Degenerative Disease

Abstract：Objective To discuss the short-term effects of minimally invasive Wiltse admission psssage MIS-TLIF in treatment of lumbar vertebra degenerative disease. Methods From July 2012 to January 2014,63 cases of patients with lum-bar vertebra degenerative diseases received by our hospital from July 2012 to January 2014 were analyzed and divided into two groups,the minimally invasive group and open group. After the surgery,the time of operation,bleeding volume in operation, post-operative drainage volume,walking time,hospitalization time,visual analogue scale( VAS)before and after the surgery,as well as the lumbago and backache of Japanese Orthopaedic Association( JOA)were compared for the patients in two groups. Results The minimally invasive Wiltse admission passage MIS-TLIF was obviously better than the open TLIF surgery in the operation time,bleeding volume in operation,post-operative drainage,length of cut,walking time,hospitalization time,VAS sco-ring in three days after the surgery and JOA score. Within the three to six follow-up visit,there were no statistical significance in the VAS and VOS score about three months after the surgery. Conclusion Wiltse admission passage MIS-TLIF operation is characterized by such advantages as small cut,short time,little bleeding,fast recovery,few complications,etc. Through the stud-y on early curative effects,this surgical method may receive the same curative effect as the traditional open surgery in treating the lumbar vertebra degenerative disease,and it is a safactory and effective surgical method.
