摘要
目的观察改良腰椎管成形术联合椎弓根螺钉内固定融合治疗腰椎管狭窄的临床效果。方法随机选取腰椎管狭窄患者150例,均分为两组各75例。观察组患者接受改良腰椎管成形术联合椎弓根螺钉内固定治疗,对照组患者仅接受椎弓根螺钉内固定治疗。测量两组患者的椎管矢状径、角度、后椎体高度等指标。采用Denis和Frankel分级评价其神经功能。结果观察组Frankel分级平均提高1.5级,对照组仅提高0.9级,两组比较差异有统计学意义(P<0.05)。观察组患者椎体前缘高度由(44.9±11.4)%增加到(57.3±7.1)%,对照组仅由(45.1±11.5)%增加到(53.8±7.9)%,两组比较差异有统计学意义(P<0.05)。结论改良腰椎管成形术联合椎弓根螺钉内固定融合治疗腰椎管狭窄临床效果好,可有效减轻患者的疼痛程度,保存神经功能和椎骨完整性。
Objective To evaluate the clinical effect of improved lumbar vertebral laminoplasty combined with pedicle screw internal fixation fusion in the treatment of patients with lumbar spinal stenosis .Methods One hundred and fifty patients with lumbar spinal stenosis in our hospital were randomly divided into two groups.The ex-perimental group（n=75） was treated with improved lumbar vertebral combined with pedicle screw internal fixation fusion laminoplasty, while the control group（ n=75） was treated with pedicle screw internal fixation fusion.The ver-tebral canal sagittal diameter, angle and height of posterior vertebral body were recorded and compared between the two groups.Denis and Frankel grading standard were applied to evaluate the neurological function.Results The av-erage Frankel grading increased 1.5 grades in the experimental group, while it was only 0.9 grades in the control group.The average Denis grading decreased 1.1 grades in the experimental group, while it was only 1.5 grades in the control group.The height of anterior vertebral body increased from （44.9%±11.4%）%to （57.3%±7.1）%in the experimental group, while it increased from （45.1%±11.5）%to （53.8 ±7.9）%in the control group.Con-clusion Improved lumbar vertebral tube keratoplasty ally pedicle screw internal fixation fusion has good effects on patients with lumbar spinal stenosis.It can relieve degree of patients′pain and save their neurological function and integrity of vertebrae.
