Analysis of stenosis application of micro minimally invasive technique for the treatment of lumbar spinal / 中国基层医药

ABSTRACT

Objective To explore the effects of minimally invasive technique in the treatment of lumbar spinal stenosis.Methods 80 lumbar spinal stenosis patients were divided into the observation group and control group,40 cases in each group,who were informed consent under the premise of the stochastic averaging grouping.The two groups were treated with microscopic invasive technology and traditional posterior bilateral fenestration decompression,and the therapeutic effect of two groups were compared.Results The average operation time of the observation group (36.2 ± 4.1) rain was obviously shorter than that of the control group (41.4 ± 5.7) min (t =2.719,P ＜ 0.05) ; the average amount of bleeding of the observation group (51.6 ± 7.3) ml was significantly lower than that of the control group(101 ± 11.7) ml(P ＜ 0.05) ; the two groups of patients before treatment JOA score had no significant difference after treatment,follow-up,JOA scores of the two groups increased significantly,the observation group increased significantly compared with the control group (P ＜ 0.05) ; the treatment group 19 cases of excellent,good in 17 cases,the excellent and good rate was 90％,control group 13 cases of excellent,good in 16 cases,the excellent and good rate was 72.5 ％,the treatment group was better than the control group (x2 =6.594,P ＜ 0.05) ; the observation group did not appear obvious postoperative complications occurred in 3 cases,the control group of nerve root injury,1 cases of intervertebral space infection,2 cases of incision leakage,the incidence of complications was 15％,observation complication rate was significantly lower than that of the control group (x2 =3.357,P ＜ 0.05).Conclusion The microscopic invasive technique for the treatment of lumbar spinal stenosis has a good curative effect,small trauma,high safety,which is conducive to improve the prognosis of patients,can gradually replace the traditional posterior bilateral fenestration decompression.
