Decompression and internal fixation combined with interbody fusion for degenerative lumbar spinal stenosis / 局解手术学杂志

ABSTRACT

Objective To study decompression and internal fixation combined with interbody fusion for degenerative lumbar spinal ste-nosis. Methods One hundred cases with degenerative lumbar spinal stenosis from January 2012 to June 2012 were researched. They were randomly divided into observation group and control group. Fifty patients in the control group,they were given treatment of interbody fusion. The observation group had 50 patients,using decompression and internal fixation on the basis of the control group. The back pain VAS score, leg pain VAS score,disc height,Cobb angle,ODI score of patients 3 months and 2 years after treatment were compared with each other. Re-sults After 3 months of treatment,back pain VAS score, leg pain VAS score,ODI scores of the observation group were lower than those of the control group,the difference was significant (P<0. 05). Intervertebral height of observation group was higher than that of control group, the difference was significant(t=4. 110 0,P=0. 000 1). After 2 years of treatment,back pain VAS score,leg pain VAS score and ODI score of the observation group was still lower than those of the control group, the difference was significant(P<0. 05). Intervertebral height of the observation group still higher(P<0. 05). The change of Cobb angle was not obvious. Conclusion Decompression and internal fixation com-bined with interbody fusion for degenerative lumbar spinal stenosis has a good effect,which is worthy of promotion in clinic.
