Abstract: 【Abstract】 Objective To compare the clinical effects between simple spinal canal decompression and decompression with fusion in the treatment of simple degenerative lumbar spinal stenosis. Methods From March 2006 to May 2011, 63 cases with degenerative lumbar spinal stenosis undergoing surgical operation were analyzed retrospectively..And the patients were followed up one year after operation. Among them,.28 cases underwent simple lumbar spinal canal decompression and 35 cases underwent spinal canal decompression with fusion..The clinical effects of two surgical procedures were evaluated by JOA (Japanese Orthopedic Association) score, ODI (Oswestry Disability Index) score and SF-36 (Short Form-36) score before and after operation. Results Better results were got in both two groups in one year follow-up period after operation..In the spinal canal decompression plus fusion group, postoperative ODI score was improved in 31.2 scores (P<0.001) and the patients- dysfunction was improved from severe to mild. In the spinal canal decompression group,.the postoperative ODI score was improved in 14.9 scores (P=0.004) and the patients- dysfunction was improved from severe to middle. Decompression plus fusion group was significantly better than that simple decompression group (P<0.01)..Postoperative SF-36 score was similar between two groups. Conclusion Surgery was effective on the patients with lumbar spinal stenosis..Compared with decompression plus fusion and simple decompression, the former-s superior to the latter in the improvement of clinical symptoms.
