Effect of intervertebral finite fenestration on lubar intervertebral disc protrusion complicated with spinal stenosis / 新乡医学院学报

ABSTRACT

Objective To investigate the effect of intervertebral finite fenestration on lubar intervertebral disc protrusion (LIDP) complicated with spinal stenosis.Methods Eighty patients with LIDP complicated with spinal stenosis were selected from May 2014 to May 2016 in the 159th Hospital of the Chinese People's Liberation Army.The patients were divided into observation group and control group according to the treatment method,40 cases in each group.The patients in the observation group were treated with intervertebral finite fenestration,lateral recess and nerve root canal decompression.The patients in the control group were treated with total laminectomy,lateral recess and nerve root canal decompression.The lumbar pain of patients was evaluated by the visual analogue scale (VAS),and the lumbar function was evaluated by using Japanese Orthopaedic Association(JOA) scoring system in the two groups before and after operation.The postoperative complications were observed in the two groups.Results There was no significant difference in VAS score of lumbar pain between the two groups before operation (t =1.638,P ＜ 0.05).The VAS score of lumbar pain after operation was significantly lower than that before operation in the two groups(t =3.182,4.303,P ＜ 0.05).The VAS score of lumbar pain in the observation group was significantly lower than that in the control group after operation(t =2.776,P ＜ 0.05).There was no significant difference in JOA score of lumbar function between the two groups before operation(t =5.170,P ＜ 0.05).The JOA score after operation was significantly higher than that before operation in the two groups (t =28.841,45.070;P ＜ 0.05).The JOA score of the lumbar function in the observation group was significantly higher than that in the control group after operation(t =52.952,P ＜ 0.05).The total effective rate in the control group and the observation group was 62.5 ％ (25/40) and 92.5 ％ (37/40),respectively;the total effective rate in the observation group was significantly higher than that in the control group(x2 =12.381,P ＜0.05).The incidence of postoperative complications in the control group and observation group was 25.0％ (10/40) and 10.0％ (4/40),respectively;the incidence of postoperative complications in the observation group was significantly lower than that in the control group(x2 =11.140,P ＜ 0.05).Conclusion Intervertebral finite fenestration can effectively reduce lumbar pain,improve the lumbar function of patients with LIDP complicated with spinal stenosis;and it has fewer postoperative complications.
