BACKGROUND: @entity1514 ( @entity1514 ) is a progressively disabling disease. Isolated or continuous @entity1514 has been frequently reported in literature, however there are very few reports of multilevel or non-continuous @entity1514 . The purpose of the study was to discuss the surgical strategy of multilevel @entity1514 and evaluate safety and efficacy of a two-stage operation regimen. METHODS: From October 2007 to May 2014, eleven @entity1 (4 males, 7 females) that underwent two-stage surgery for multilevel spinal stenosis were retrospectively reviewed. The follow-up period lasted at least 12  months. Demographic data, radiological findings as well as operative data were collected. Postoperative functional outcomes evaluated by the modified Japanese Orthopedic Association score (mJOA) and complications were analyzed. RESULTS: The @entity1 ranged in age from 30 to 65  years (average, 50.2        11.8  years), and comprised 4 @entity1 and 7 @entity1 . All @entity1 exhibited significant improvements in @entity51 . The mJOA score improved from a mean of 3.5        2.2 preoperatively to 4.6        2.3 before second-stage surgery and to 7.5    2.2 at final follow-up. The improvement was statistically significant in the average mJOA improvement rate at final follow-up. No staging-related complications were noted in this study. CONCLUSIONS: Staged surgery can effectively achieve neurological functional recovery in @entity1 with multi-segment spinal stenosis in @entity1514 and lumbar regions, with favorable efficacy and safety. Yet, slight @entity16 was observed during the intervals of these two index surgeries.
