OBJECTIVE: To discover the benefits of minimally invasive expandable in surgical procedure of lumbar discectomy and interbody fusion and inner fixation.
METHODS: The medical information of 48 sufferers who underwent lumbar discectomy and interbody fusion and inner fixation from January 2010 to March 2016 was retrospectively analyzed. In line with the admission queue, the sufferers had been randomly assigned into channel group (26 instances) or conventional group (22 instances). In channel group, surgical strategy of minimally invasive expandable channel was utilized, and in conventional group, open posterior operation strategy (together with posterior lumbar interbody fusion and transforaminal lumbar interbody fusion, and so on.) was utilized. In channel group, there have been 20 males and 6 females, aged from 43 to 74 years with a mean of(56.6±5.1) years; course of illness was ranged from four to 22 months with a mean of (6.7±1.eight) months; 1 case was difficult with diabetes, 6 instances had been difficult with hypertensive illness, and a pair of instances had been difficult with arrhythmia. In conventional group, there have been 15 males and seven females, aged from 43 to 73 years with a mean of(55.9±four.6) years; course of illness was ranged from four to 26 months with a mean of (6.2±2.1) months; 2 instances had been difficult with diabetes, 5 instances had been difficult with hypertensive illness, and 1 case was difficult with arrhythmia. Operation time, bleeding quantity, and hospitalization time had been in contrast between two teams and visible analogue scale(VAS), Oswestry Incapacity Index(ODI), bone fusion data, and issues correlated with incision had been noticed in two teams.
RESULTS: All 48 sufferers had been adopted up for greater than 6 months. Postoperative VAS and ODI had been considerably improved (P<zero.01), however three and 6 months after operation, there was no important distinction in VAS between two teams, and ODI rating of channel group was decrease than that of conventional group(P<zero.01). Operation time, bleeding quantity, hospitalization time in channel group respectively had been (167.three±30.2) min, (786.eight±147.eight) ml, (12.three±2.four) d, and in conventional group had been (197.5±48.7) min, (786.eight±147.eight) ml, (16.5±three.eight) d, there was important variations between two teams. There was no important distinction in fusion fee and fusion time between two teams. There have been four instances and seven instances developed incision associated issues in channel group and conventional group, respectively. The distinction between two teams was important(P<zero.01).
CONCLUSIONS: In contrast with standard surgical procedure minimally invasive lumbar discectomy and interbody fusion and inner fixation has benefits of much less trauma, shorter operative time and higher purposeful restoration.
