【摘要】:目的 :评价退变性腰椎侧凸(degenerative lumbar scoliosis,DLS)减压截骨术中应用超声骨刀的安全性和有效性。方法:选择2008年2月~2016年12月在我院行后路减压、Ponte截骨、长节段(≥5个椎体)固定融合术且年龄不小于45岁的54例DLS患者,根据减压截骨操作主力工具的不同分为超声骨刀组(28例)和传统工具组(26例)。比较两组患者器械并发症例数、出院时神经功能恶化例数、手术时间、估算出血量、单个融合椎体出血量和自体血回收量等指标。结果:虽然超声骨刀组减压椎板数、Ponte截骨数和切除间盘数显著多于传统工具组(P0.05),但是两组的器械并发症例数和出院时神经功能恶化例数无统计学差异(P0.05)。两组手术时间无统计学差异(P0.05),且超声骨刀组估算出血量、单个融合椎体出血量和自体血回收量显著低于传统工具组(834.0±354.4ml vs 1467.3±804.9ml,P=0.002)(120.8±57.2ml vs 191.4±88.4ml,P=0.003)(342.3±179.9ml vs552.2±295.2ml,P=0.003)。结论 :应用超声骨刀完成DLS减压截骨手术安全、有效,超声骨刀能显著减少术中出血量,且在安全性方面至少不亚于传统工具。
