后路小切口开窗减压融合术联合经皮固定与传统开放椎弓根螺钉固定治疗胸腰椎骨折的临床研究

目的比较后路小切口开窗减压融合术联合经皮固定与传统开放椎弓根螺钉固定治疗胸腰椎骨折的临床效果。方法胸腰椎骨折患者102例,按随机数字表法分为观察组和对照组各51例,观察组进行后路小切口开窗减压融合术联合经皮固定术式,对照组进行传统开放椎弓根螺钉固定术式,比较两组手术指标、脊柱改良情况、疼痛视觉模拟(VAS)、Oswestry功能障碍指数(ODI)、日本骨科协会评估疗效(JOA)评分,并记录手术并发症发生情况。结果观察组手术时间长于对照组,切口长度、术中出血量、引流量、住院时间少于对照组,术后VAS、ODI、JOA评分优于对照组(P<0.05);两组术后矢状面Cobb角、椎体前缘高度、矢状位指数、伤椎楔变角均较术前改善(P<0.05),但组间比较差异无统计学意义(P>0.05);两组均未发现并发症情况。结论两种术式均能有效治疗胸腰椎骨折,但后路小切口开窗减压融合术联合经皮固定术式切口小、出血量小、术后疼痛轻、术后恢复快,且不会增加手术风险。
