Decompression fusion and internal fixation combined with intervertebral fusion device in treatment of degenerative lumbar spinal stenosis

Abstract

Objective To explore the clinical effect of decompression fusion and internal fixation combined with intervertebral fusion device in the treatment of degenerative lumbar spinal stenosis. Method 80 patients with degenerative lumbar spinal stenosis treated at our hospital from January, 2016 to January, 2017 selected as research objects. According to the even and odd admission date, the patients were divided into a control group and an observation group. The control group were treated wtih intervertebral fusion, and the observation group wtih decompression fusion and internal fixation in combination with intervertebral fusion. The effects 3 months after the treatment and 2 years’ follow-up were compared between these two groups. Results The scores of VAS and ODI were (2.3±1.0) and (4.1±2.1) in observation group and were (3.7±1.3) and (5.9±3.2) in the control group 3 months after the operation, and were (2.7±1.2) and (5.3±1.0) in the observation group and were (3.5±1.4) and (6.0±1.5). There was no statistical difference in the Cobb angle between these two groups 3 months after the operation (P>0.05); two years after the operation, the Cobb angle was significantly lower in the observation group than in the control group (P<0.01). The vertebral space height was significantly higher in the observation group than in the control group 3 months and 2 years after the surgery (both P<0.01). Conclusion Decompression fusion and internal fixation combined with intervertebral fusion device in the treatment of degenerative lumbar spinal stenosis is effective.
