This study reviewed the results of the conservative treatment and operative treatment for lumbar canal stenosis.
161 patients with lumbar canal stenosis were inrestigated in this study. 101 cases were degenerative canal stenosis and 60 were degenerative spondylolisthesis.
The average age at admission was 66.9 years and the average follow-up period was 1 year and 9 months.
We evaluated their JOA score and findings of myelogram and CTM at the time of admission.
The JOA score and findings of myelogram of degenerative spondylolisthesis were severer than those of degenerative canal stenosis.
All cases undergoing conservative treatment showed only radicular symptoms. Operations were performed in all the patients with cauda equina syndrome.
Degenerative canal stenosis cases with radicular symptoms, showed correlation between the JOA score and prognosis. In the same cases, the distance of the bilateral articular prosess and the anteroposterior diameter of the lateral recess measured by CTM correlated with prognosis.
