65岁以上老年人腰椎管狭窄症手术治疗的临床分析

目的 探讨老年人腰椎管狭窄症手术治疗的可靠性、手术方法及手术后效果。方法 回顾性分析1990年1月至2005年6月我院收治的65岁以上老年腰椎管狭窄症患者304例，其病程3~360个月，平均139．2个月，手术方法主要为单纯全椎板切除减压术、多节段椎板开窗减压术、全椎板及侧隐窝神经根管减压＋椎弓根螺钉固定术＋椎体间或（和）横突间植骨术。结果 术后264例恢复良好或优，优良率86．8％；34例感觉与术前比，变化不大；有6例较术前加重；无术中死亡患者。结论 老年患者多病程长、术前各种并存症多，掌握手术适应证应慎重，术前详细检查并积极地处理并存症、多科共同协作是手术成功的关键。手术应在充分的减压基础上尽量减少损伤，最短时间完成手术，根据实际合理的内固定促进植骨融合。术后积极的功能锻炼、早期的下床活动是保证手术效果、减少术后并发症的关键。

Clinical analysis on surgical treatment of lumbar spinal stenosis in elderly patients aged 65 years and over

Objective To evaluate the surgical results of spinal stenosis in the elderly and to investigate the indications , surgical technique and factors which may contribute to the outcome. Methods A retrospective study was held, 304 patients aged 65 and over who had different kinds of decompression laminectomy for lumbar spinal stenosis between Jan 1990 and Jun 2005 were recruited. The mean patient age at surgery was 70.4 years (65-86 years old). Results One hundred and seventy-five cases had co-existing illnesses, 62 had concomitant degenerative spondylolisthesis, 138 had spinal instrumentation. Functional results were graded as excellent, good, fair and poor: 86. 8% excellent or good, 11. 2% fair and 6 cases poor. Four patients had re-operations because of post operation hematomas. Multivariate analysis revealed that age, sex, co-morbidity score, number of levels decompressed, and degenerative spondylolisthesis did not predict bad outcomes. Conclusions The surgical results of spinal stenosis in the elderly are favourable and comparable to those reported for the general population . Carefully perioperative preparation is very important in the treatment of elderly patient with lumbar spinal stenosis.
