【摘要】 目的：探讨有限减压植骨融合术和椎板切除减压融合内固定术治疗老年退变性腰椎管狭窄症的效果。方法：选取2017年1月-2018年1月笔者所在科室收治的老年退变性腰椎管狭窄症患者60例，按照随机数字表法分为A、B组，各30例。A组采取有限减压植骨融合术治疗，B组采取椎板切除减压融合内固定术治疗。对两组术中出血量、手术持续时间及下肢疼痛评分(JOA)优良率进行比较。结果：A组术中出血量少于B组，手术持续时间短于B组，差异均有统计学意义(P<0.05);A组JOA评分优良率为83.33%，B组JOA评分优良率为86.67%，两组JOA评分优良率比较，差异无统计学意义(P>0.05)。结论：有限减压植骨融合术和椎板切除减压融合内固定术治疗老年退变性腰椎管狭窄症均具有良好的效果，但前者术中出血量更少，手术持续时间更短，值得临床应用。
