Abstract：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.
