Objective:To discuss the selection, experience and clinical curative effect of individual operation for degenerative lumbar spinal stenosis (DLSS) in aged people.Methods: A retrospective analysis was made on clinical data of 92 patients with DLSS from September 2010 to February 2014 who were treated with individual operation exclude those who suffered from lumbar isthmic spondylolisthesis. The average age was 70.3 years old(range from 65-84 years old), including 40 males and 52 females. All the patients were performed posterior approach operation with individual strategy according to the difference of physical condition, bone condition and the type of stenosis. In those people, 26 cases underwent hemilaminectomy(including submersible decompression if necessary), 43 cases underwent central laminectomy with decompression of lumbar root canal and 23 cases underwent total laminectomy combined with lumbar interbody fusion and internal fixation and internal fixation.According to the modified Japanese Orthopaedic Association Scores (JOA) of lumbar diseases, the outcome of the preoperation and postoperation were evaluated. Results: 92 cases were followed up for 4-41 months, the average follow up period was 18.6 months. No dead case, no paralytic case, one cerebrovascular complication, two infection and 4 cerebrospinal fluid leakage occur. The mean postoperative improvement rate was 78.4%, 81.3% and 80.6%, respectively. 24 cases were excellent, 59 cases were good and 9 cases were fair. Conclusion: Degenerative lumbar spinal stenosis in aged is complex, individual operation strategy according to the difference of physical condition, bone condition and the type of stenosis is necessary and the outcome of operation relatively good. Discectomy and fusion combined internal fixtion should be used reasonably.
