Abstract:
Objective To observe the effect of Cage interbody fusion on degenerative lumbar spondylolis thesis. Methods Totally 128 patients with degenerative lumbar spondylolisthesis were selected and divided into study group and control group according to the random number table. The patients in control group were treated with vertebral reduction and single posterolateral transverse interbody fusion and internal ?xation. The patients in study group were treated with vertebral reduction. The Cage interbody fusion and internal ?xation was used for treatment. The height of intervertebral space, complication rate and quality of life (QOL) scores were compared between the two groups. Results The height difference of the intervertebral space before and after treatment in the control group was ( 12. 3± 0. 41) mm one month after treatment, which was not significantly different from the study group ( 12. 1 ± 0 . 6 ) mm (P > 0 . 05). The height differences of the intervertebral space before and after treatment in the control group were ( 11. 3± 0. 3) mm after 4 months, ( 10. 3± 0. 2) mm after 6 months, ( 11 . 3± 0 . 2 ) mm after 12 months and ( 10. 1± 0 . 1 ) mm after 24 months, which were significantly higher than those in the study group [(12.3 ± 0.5) mm, (12.1 ± 0.6) mm, (12.3 ± 0.5) mm and (12.1 ± 0.3) mm, P<0.05]. After treatment, the QOL scores of study group were (89.3±3.5) for the physical condition, (85.3±5.8) for the behavioral score, (85.89±6.3) for the self-assessed quality of life score, and (89.3±4.9) for the social activity score, which were signi?cantly higher than the physical condition score of the control group ( 78 . 2 ± 2 . 4 ). The score was ( 71 . 6 ± 2.9), the self-assessed quality of life score was (70.5±3.2), and the social activity score was (65.4±3.7) (P<0.05). The complication rate in the control group was 23. 5%, which was higher than that in the study group ( 4. 7%, P <0.05). Conclusion Radial reduction and Cage interbody fusion and internal ?xation for the treatment of degenerative lumbar spondylolisthesis are effective, and can promote bone graft fusion, less complications and high patient satisfaction.
