摘要 目的探讨微创棘突间内固定(Coflex)治疗腰椎管狭窄症及腰椎失稳症的疗效。方法将椎管狭窄症及腰椎失稳症患者60例分为3组,每组20例:融合组应用传统的脊柱融合术处理,Coflex组给予微创棘突间内固定治疗,保守组给予保守治疗。记录并比较3组VAS评分及X线的相应椎节活动度,同时对融合、Coflex组两组手术失血量、手术切口大小、手术时间及住院时间进行比较。结果 Coflex组住院时间、手术时间、手术失血量少于融合组,手术切口小于融合组(P<0.01);治疗后随访两手术组的腰、腿痛VAS评分均小于术前(P<0.01);3组间治疗前腰、腿痛VAS评分比较差异无统计学意义(P>0.05),3组治疗前后比较差异有统计学意义(P<0.05);治疗后Coflex组手术节段的节段活动度(ROM)与术前比较差异无统计学意义(P>0.05),3组治疗前相应椎节段ROM差异无统计学意义(P>0.05),Coflex组治疗后ROM明显大于融合组(P<0.01);治疗后Coflex组上邻节段ROM与术前比较差异无统计学意义(P>0.05),治疗后融合组ROM明显大于术前(P<0.05),术前两组上邻节段ROM差异无统计学意义(P>0.05),治疗后融合组ROM明显大于Coflex组(P<0.05),保守组治疗前后活动度无明显改变。结论微创棘突间Coflex内固定治疗腰椎管狭窄症及腰椎失稳症在改善临床症状方面与传统后路椎间融合术无明显差异,但患者住院时间、手术时间和术中失血量较少;微创棘突间Coflex内固定能保留可控制的手术节段椎间隙活动度,有效减少上邻节段腰椎间隙活动度。
